On my wiki implemented by the MediaWiki interface, I am receiving a Failed to Parse (Unknown Error) for the LaTeX in the page. I checked the LocalSettings.php file, and I have set the proper variable($wgUseTeX) to true.
If it helps, the error message before this was a Failed to Parse(Missing texvc executable), but I "fixed" it to the best of my knowledge by running "make" inside the math directory and installing the texvc executable there. I tested texvc and it works on the commandline.
Could there be anything that I am missing?
aptitude install ocaml
cd /math
make clean
make
Found the answer here: MediaWiki Forums LaTeX Error
It seems that I had to clear the math directory except for the original files, rebuild ocaml, and finally rebuild texvc.
Adding this to LocalSettings solved it for me. Just needed to make the directory calls accurate. Tedious.
$wgUseTeX = true;
$wgUploadDirectory = "{$IP}/images";
$wgUploadPath = "{$wgScriptPath}/images";
$wgMathPath = "{$wgUploadPath}/math";
$wgMathDirectory = "{$wgUploadDirectory}/math";
$wgTmpDirectory = "{$wgUploadDirectory}/tmp";
$wgTexvc = "{$IP}/math/texvc";
Have a look at the README file, paying particular attention to "Ensure that the temporary and math directories exist and can be written to by the user account the web server runs under; if you don't control the server, you may have to make them world-writable."
If that does not help, edit render.ml, comment out the block that says "Commenting this block out will aid in debugging", and re-run make. This will leave all temporary files (including the TeX log) so that you can hopefully see what went wrong.

I'm using powerline, bash, and iterm2 on mac. I also installed gitstatus, but that didn't work when I installed it two days ago, and powerline worked just fine yesterday without gistatus functioning. Today, when I booted up the terminal, this error showed instead of the prompt.
Any advice? Where can I find the full log of the errors/interpret this message? Alternatively, how can I pinpoint which file has an error on line 55?
There error was in a color config file for the github integration. I was missing a comma at between lines. I believe it was in this file .config/powerline/colorschemes/default.json or another json related to it; see here.
Ultimately, I recommend moving to powerlevel10k. You can configure it to look exactly like powerline, but it a) updates cleanly (compared to powerline where if you update your python it breaks horribly) and b) comes with a really good customization setup and c) lets you use zsh + oh-my-zsh which gives so much additional functionality
I'm trying to learn Yeoman, but find the official documentation severely lacking. I've found the remote() function which appears to download a GIT repository but whatever I do I can't get it to work without throwing errors.
Here's what I have:
this.remote('powerbuoy', 'SleekWP', 'master', function (err, remote) {
if (err) {
this.log(err);
return err;
}
remote.copy('.', this.destinationPath('wp-content/themes/sleek/'));
}.bind(this));
What I'm hoping would happen here is that the https://github.com/powerbuoy/SleekWP/ repo is downloaded and moved to wp-content/themes/sleek/. What happens instead is I get:
fs.js:603
var r = binding.read(fd, buffer, offset, length, position);
^
Error: EISDIR: illegal operation on a directory, read
Is there a better documentation or a tutorial explaining all these basics somewhere? I'd love to know how to copy files without each copy being printed to the console too for example. This all seems pretty basic but http://yeoman.io/authoring/ is very sparse.
Ok, so apparently the solution was to use remote.bulkDirectory() instead of remote.copy().
Edit: However, reading the "documentation" (can barely be called that) it says that "You should never use this method, unless there's no other solution." (http://yeoman.io/generator/actions_actions.html)
So if anyone knows of the proper way to do this I'd love to know.
I switched to the fs-extra package and used cacheRoot() and destinationRoot() to copy the directory instead:
fs.copy(this.cacheRoot() + '/username/Project/branch/', this.destinationPath('destination/path/')
In a mozille extension I run:
SecSess.Logger.info("ctypes test");
Components.utils.import("resource://gre/modules/ctypes.jsm");
SecSess.Logger.info("1");
this.lib = ctypes.open("libcrypto.so");
SecSess.Logger.info("2");
var a = new Uint8Array(1<<10);
SecSess.Logger.info("3");
var ptr = new ctypes.uint8_t.ptr(a.buffer);
SecSess.Logger.info("4");
Why this ugly logging after each step you might ask? Well this code fails without showing me an error. (or at least I can't find the error message)
This is printed:
ctypes test
1
2
3
So the 5th log message is never printed which means the following statement never completes:
var ptr = new ctypes.uint8_t.ptr(a.buffer);
This is a simplified version of some old code I have to work with and which I also found online as being valid. However it doesn't work. This add-on wasn't developped using the new SDK with jpm. Quite frankly I don't know how and when it was developped but I need to run some tests on it. It comes with a few source files ordered in a components and a modules directory and a chrome.manifest and install.rdf in the root. I copied these files to the extension directory of Mozilla in order for it to work. The extension executes but there seems to be a problem with ctypes. Aren't ctypes fully supported anymore or are these old style add-on no longer valid for the modern Firefox?

Roel
I think they landed a a patch to disallow making a pointer from buffers. I'll double check.
Edit:
Ah per this: https://developer.mozilla.org/en-US/docs/Mozilla/js-ctypes/Using_js-ctypes/Working_with_ArrayBuffers, you don't have to wrap it with a ctypes.uint8_t.ptr just pass it like a.buffer to wherever you need it. :)
For some specific purpose, I need to install some fonts on the instances. It comes as no surprise when I choose StartUp Task to accomplish that goal. I've configured the Service Definitions as below:
<Startup>
<Task commandLine="Fonts\InstallFonts.vbs" executionContext="elevated" taskType="simple" />
</Startup>
Nothing special here. Click and run, it failed. However, if I changed the commandLine into a cmd file including just nonsense, namely "echo test", the instance would run without ado. So there must be some issue with my scripting:
Const FONTS = &H14&
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace(CreateObject("Scripting.FileSystemObject").GetAbsolutePathName("."))
Set fontFolder = objShell.Namespace(FONTS)
Set rxTTF = New RegExp
rxTTF.IgnoreCase = True
rxTTF.Pattern = "\.ttf$"
Set fso = CreateObject("Scripting.FileSystemObject")
FOR EACH FontFile IN objFolder.Items()
IF rxTTF.Test(FontFile.Path) THEN
IF NOT fso.FileExists(fontFolder.Self.Path+"\\"+FontFile.Name) THEN
FontFile.InvokeVerb("Install")
END IF
END IF
NEXT
The script should come with no error because I've tested it either locally or on Azure via RDP.
Weirdly, when I put it in the startup, the role just won't start. The instance just keeps recycling and at last says "I'm unhealthy". Even if I deprecate the vbs into just one line of code - the first line Const FONTS = &H14&, it just won't start. Even if I wrap the invocation of the vbs into a cmd file, namely to put something like "cscript /B file.vbs", it won't run either.
So I'm concluding that there must be some issue regarding the communication between the script and the Windows Azure monitor. I'm not sure but I think the monitor might take the running script as a failed task. Besides, I'm wondering if there is any timeout for the startup task, which should be the problem though, because the script can guarantee that no UI interaction block the process.
Any idea would be greatly appreciated.
I am sure you must have but just for the sake of confirmation, have you checked that the InstallFonts.vbs file is exported with the package? I mean is the "Copy To Output Directory" is set to "Copy Always/Copy if newer"?
This is pretty much possible that it is not able to locate your file.
You need to write a cmd file as a start up task. In your cmd file, you can call the vbs file using the command line tool cscript.
Azure start up can compile only command line tools.
Oh god, I finally solved the problem.
Although the compiler does quite a good job usually, it allows to use subfolder as a source of command, I mean something like "Subfolder\command.cmd", which will not work always. I've seen examples in which people put whatever we do in cmd in commandLine property, such as "copy fileA fileB" and it really works. But as for vbs, you need to be cautious. Until now I still don't know what's under the cover, but there should be some problem with the path. And the solution is definitely simple, instead of doing the subfolder work for tidiness, just leave the command file in the root folder like most people do:
<Startup>
<Task commandLine="InstallFonts.vbs" executionContext="elevated" taskType="simple" />
</Startup>
And thank you all the same, Kunal. :)
I am extremely new to Informix and am having some trouble trying to get sqldemo installed.
Set up so far:
openSuse 12.1 (32 bit)
Informix Growth Edition 11.70 UC6
Informix SQL Developer 7.50 UC6
Informix RDS 7.50 UC6
Informix ID 7.50 UC6
After struggling a few days and a lot of reading of http://publib.boulder.ibm.com/infocenter/idshelp/v117/index.jsp, I managed to get Informix installed and On-line.
I also opted to install the demo database instance that comes with the installation.
I now and attempting to get started with Informix 4GL by Example.
I am trying to get the sqldemo database up. I don't know if it will replace the previous instance installed with Informix, but that is a different problem.
Right now as per the document, running the following should set up the DB:
sqldemo stores2t -log
I however get an error: "Invalid Locales set !!".
I have tried looking up this error and also in the documentation.
I have tried setting the CLIENT_LOCALE and DB_LOCALE in my .profile file.
For example:
export CLIENT_LOCALE=en_US.CP1252 and
export DB_LOCALE=en_US.819
This has not helped.
A push in the right direction, or perhaps some other documentation I could read that would explain things better would really be appreciated.
If any other information is required from me, please do not hesitate to ask.
Update 1
Thanks so much for the response.
A couple of things firstly that I have tried since your post.
Changed the the CLIENT_LOCALE and DB_LOCALE as you specified - Same error - So i removed it as you said it should not be set.
Fixed a problem in my PATH and made sure it has /usr/informix/bin - Same Error
INFORMIXDIR is /usr/informix
INFORMIXSERVER is ol_informix1170 (This is from the database that was installed with the informix install, don't know if this must be changed? and if so to what?)
Ran the script you mentioned, result :
INFORMIXDIR=/usr/informix
INFORMIXSERVER=ol_informix1170
INFORMIXSQLHOSTS=/usr/informix/etc/sqlhosts
LANG=en_US.UTF-8
ONCONFIG=onconfig
I noticed I had set the language to UK, which made the Locales en_gb instead if en_us, so tried changing that in my .profile, which did not help, so also tried changing the language to US and the locales to en_us, but this made no difference.
As for what you said about the sqldemo script and the already installed db, It is fine if that db is removed as this is just a test VB box for me to learn on.
Could the $INFORMIXSERVER set as ol_informix1170 be the problem?
Thank you once again for the help.
Neill
Update 2
Thanks again for the response.
A few things to note.
The dbenv results I posted is all that shows which i assume/presume (uh-oh) means that the other environment variables are not set. Which of the environment variables you posted are absolutely necessary for it to work?
As above, Where would I find the terminfo file, or does this need to be created?
As above, the SQLEXEC variable... where would I find sqlrm? I can somewhat remember from the documents I have read I think it should be $INFORMIXDIR/lib? but I only have an esql directory. Is this correct.
Barring that something in the first 3 above is not causing more problems, when trying your suggestion of DEMOPATH=en_us/0333 sqldemo stores2t -log I receive the following error:
Sorry, cannot read the mkstores3 program required to build the demonstration database. Check the /etc subdirectory of INFORMIXDIR (/usr/informix).
Checking /usr/informix/etc shows indeed that there is no mkstores3 file.
Attempting your further note of isqldemo, I get the following error:
/usr/informix/bin/isqldemo: line 58: /usr/informix/demo/sql/en_us/e01c/isqldemo: No such file or directory.
I guess this makes perfect sense as there is no e01c directory, just the 0333 directory.
Right now anything you can tell me would indeed be a consolation because my newb-ness to generally Linux and definately Informix is a big factor. Interesting that this bug has been around for so long. I guess way more experienced folk than I figured out how solve it on their own, or just never bothered with the sqldemo.
I guess that will teach me to read this:
INFORMIX-4GL by Example
Version 4.1
July 1991
Going to check now if any updated text exists, but would still appreciated more help in solving this problem. Do you think reverting to a previous snapshot before Informix was installed and not opting for the ol_informix1170 database to be included could be a possible solution? I wouldn't really see that it would be, but what do I know.
Many many thanks for your continued time and effort.
Regards,
Neill
Update 3
So I see indeed the document I was reading is ancient. I have found an updated one (2002) which uses a different script (dbaccessdemo7).
I tried running that, have run into an error, but tomorrow is another day.
For now I am going to mark this as solved because of the bug detected and resolved. I am not going to put more time and effort into sqldemo.
Thank you so much, and if I struggle with dbaccessdemo 7, I will post a new question.
Regards,
Neill
The sqldemo script won't create a new server; it may clobber your existing database (a single server may house multiple databases; indeed, there are 4 sys* databases created when a server is initialized) but it won't harm your server otherwise.
Probable cause of the error
The normal problem with invalid locales is that you've not set $INFORMIXDIR. You need $INFORMIXDIR set unless /usr/informix is (a symlink to) the correct location. You also need $INFORMIXSERVER set, and you usually need $INFORMIXDIR/bin on $PATH. Strictly, $INFORMIXSERVER is the only mandatory variable; in practice, you worry about the other two too.
The $INFORMIXDIR setting is used to locate the locale information (which is found in $INFORMIXDIR/gls) and the message files (which are found in $INFORMIXDIR/msg).
Note that CP1252 is a Windows code page. Normally on Unix, you'd either not set CLIENT_LOCALE or DB_LOCALE, or you could set them to:
export CLIENT_LOCALE=en_us.8859-1
export DB_LOCALE=en_us.8859-1
or you can choose another more appropriate (to you) locale. The 8859-15 locale includes the Euro symbol, for example, or the utf-8 locale dictates UTF-8 in the database. But, for initial debugging, stick with the 8859-1 locale, aka 819 or 0333 (all based on the IBM CCSID). If it doesn't work with 8859-1, then we have one set of problems; if it works with 8859-1 but not some other codeset or locale, then we have a different set of problems.
Follow-up info if the solution above fails
If that isn't the trouble, then I'll ask for some more details — notably, your Informix environment as reported by the dbenv script below:
: "#(#)$Id: dbenv.sh,v 2.11 2007/09/02 00:18:58 jleffler Exp $"
#
# Printout INFORMIX database environment
informix1="DB[^=]|DELIMIDENT=|SQL|ONCONFIG|TBCONFIG|INFOR"
informix2="ARC_|CLIENT_LOCALE=|GL_|GLS8BITSYS|CC8BITLEVEL|ESQL|FET_BUF_SIZE="
informix3="INF_ROLE_SEP=|NODEFDAC=|ONCONFIG|OPTCOMPIND|PDQ|PSORT"
informix4="PLCONFIG|SERVER_LOCALE|FGL|C4GL|NE_"
informix5="TCL_LIBRARY|TK_LIBRARY"
informix="$informix1|$informix2|$informix3|$informix4|$informix5"
system="COLLCHAR=|LANG=|LC_|LD_LIBRARY_PATH(_64)?=|PATH=|SHLIB_PATH="
jlss="IXD(32|64)?="
env |
egrep "^($informix|$system|$jlss)" |
sort
It's an old script; that's why the shebang is missing.
Second set of diagnosis
I was hoping for the complete output of the dbenv script; it is surprising how often something shows up. However, given what you've said, it is likely to be OK.
The INFORMIXSERVER setting sounds fine.
I'm struck by the LANG=en_US.UTF-8 setting; Informix does pay attention to $LANG and the $LC_* variables (that's why dbenv prints those out). That may be a factor in the problem. However, I would have expected CLIENT_LOCALE and SERVER_LOCALE to deal with that if it was the problem. Also, on my Mac, I have LANG=en_US.UTF-8 and yet I can connect to (8859-1) databases OK.
This is beginning to look like an install problem...or sqldemo problem...
I transitioned from a Mac to a RHEL 5 (archaic) x86/64 machine, and tried running sqldemo over there:
$ dbenv

$
Oh yeah? No; my locales are fine, thank you!
Well, so be it...I can reproduce your problem! That's step 1. Step 2 is to look at the expletive deleted script.
PRODUCT=sql
DEMOFILE=sqldemo
DEFLANG=en_US.8859-1
INFORMIXDIR=${INFORMIXDIR:=/usr/informix}
INFENV=$INFORMIXDIR/bin/infenv
CONVLOC=$INFORMIXDIR/bin/convloc
if [ $# -gt 0 -a "X$1" = "X-e" ] ; then
LOCALE=$DEFLANG # -e means en_US.8859-1 required
shift
else
LOCALE=`$INFENV DBLANG` # get DBLANG value
if [ "x${LOCALE}" = "x" ]; then
LOCALE=`$INFENV CLIENT_LOCALE` # try CLIENT_LOCALE instead
if [ "x${LOCALE}" = "x" ]; then
LOCALE=`$INFENV DB_LOCALE` # finally default to DB_LOCALE
fi
fi
fi
if [ "x${LOCALE}" = "x" ]; then
LOCALE=$DEFLANG # finally default to DB_LOCALE
fi
export LOCALE
if [ "x${DEMOPATH}" = "x" ]; then
echo "Invalid Locales set !!"
else
exec $INFORMIXDIR/demo/$PRODUCT/$DEMOPATH/$DEMOFILE $*
fi
exit $?
Note that test for ${DEMOPATH}; note that DEMOPATH is not set in the script. So, we've got to get it set. What to? Well, ls $INFORMIXDIR/demo/sql shows that there are various locale-specific sub-directories (en_us,
ja_jp,
ko_kr,
th_th,
zh_cn,
zh_tw) and under the en_us directory there's 0333 (only).
Please run:
DEMOPATH=en_us/0333 sqldemo stores2t -log
This more or less worked for me — I believe it would work for you. I have a slightly unusual setup in that I have just I4GL (p-code and c-code) and ISQL in the $INFORMIXDIR; the server is run out of a different directory. This means I don't have server utility programs like dbload (specifically) in $INFORMIXDIR/bin. When the sqldemo script tried to load the data with dbload, therefore, it failed for me. It would work for you because you have all the Informix software in a single directory. To add insult to injury, it runs the dbload program by explicit path, so I can't futz my PATH to make it available.
This should get you going. I have a bug to report...it is CQ idsdb00244894.
I'm sorry that you ran into so much trouble. You shouldn't have done so.
