yaws failed to start yet erlang works very well - erlang

I downloaded and installed win32 yaws-1.98 installer for my win7 and tried to start it from windows command prompt with: yaws -i. the result I got is just as right below. where I have placed # was a simicolon.
Failed to create the process entirely.
Tried to invoke: erl.exe -pa "C:/Program Files/Yaws-1.98/ebin" -conf "C:\Program Files\Yaws-1.98\yaws.conf" -run yaws -yaws id default #
Make sure you have erl in your environment PATH
after some research, I placed the following paths in the O.S environment variables list separated by semicolon, first under the name ERL_LIBS and then PATH all with no change :
C:\Program Files\erl5.10.3\erts-5.10.3\bin
C:\Program Files\erl5.10.3\bin
what could I be missing
...s.b help.

Aldec Active-HDL VSimSA Converting BDE files into VHDL files

I'm trying to automate compiling my Aldec block designs using the VSimSA shell instead of using the Aldec GUI. Currently, I am able to get the following command to work in the GUI console with the desired results (producing a converting a .bde file to a .vhd file in the compile directory as well as using the VHDL compiler on the .vhd file).
'''
acom -w -O3 -e 100 -work gen8_ieee -2008 -d <path to compile directory> -s <path to library.cfg> -j <path to projlib.cfg> <BDE file path>
'''
When issuing the same command in the VSimSA shell, I receive the following error. This error occurs for multiple lines in the bde file. If I run the same command in VSimSA on a .vhd file, it compiles with no issues.
*Error: COMP96_0010: <BDE file path> : (12, 36) : Invalid literal.*
Line 12 in the BDE file :
#DEFAULT_RANGE0="<range<index=\"0\"><name=\"bist_cctrl\"><left=\"bcw-1\"><direction=\"downto\"><right=\"0\"><initial_value=\"\"><delay=\"\">>"
Is there another command that needs to be issued first to convert the BDE file to a VHDL file prior to running the 'acom' command? The help documentation states the 'acom' command works with BDE files.

How can I compile an Erlang file with includes from the erl shell?

erlc -I <abspath-to-include-dir> <module>.erl on the command line correctly compiles <module>
But in the Erlang shell (erl), the following produces errors with "cannot find include file":
c(<module>, [{i, <abspath-to-include-dir>}]).
Why? Shouldn't the behavior of these two ways of compiling files be the same?
Try writing the path as a list of directories, as in {i, [".../here/", ".../there/"]}, even if it's just a single directory.

Unit not found: 'System.pas' or binary equivalents (.dcu) : Compiling on jenkins

I'm using Jenkins to generate automatic build every 15 minutes for a test project.
When compiling for Delphi itself does not give a problem, now when I run by jenkins it gives the following problem ...
C:\Program Files (x86)\Embarcadero\RAD
Studio\7.0\Bin\CodeGear.Delphi.Targets(136,3): error : Project1.dpr(1)
Fatal: F1027 Unit not found: 'System.pas' or binary equivalents (.dcu)
I have already tried to run by windows command this way.
cd "C:\Users\carlos.santos\Desktop\teste"
call build.bat
And Build.bat in this way.
call "C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\bin\rsvars.bat"
msbuild "Project1.dproj" /p:config=Release /p:Warn=0
I have already tried to run by the Rad Studio plugin itself for Jenkins this way and it also did not work.
I have already seen in some forums that if I have many paths or do not have the default paths of Delphi in Library path can be a problem, but I have tested this too and nothing ..
Here are the paths I have.
$ (BDS) \ lib; $ (BDS) \ Imports; $ (BDS) \ Lib \ Indy10; $
(BDSCOMMONDIR) \ Dcp; $ (BDS) \ include; $ (BDS) \ RaveReports \ Lib;
$ (BDSCOMMONDIR) \ Bpl; $(BDS)\lib\debug; $(BDS)\bin; $(DELPHI)\Bin;
The Content of rsvars.bat are there:
#SET BDS=C:\Program Files (x86)\Embarcadero\RAD Studio\7.0
#SET BDSCOMMONDIR=C:\Users\Public\Documents\RAD Studio\7.0
#SET FrameworkDir=C:\Windows\Microsoft.NET\Framework\v2.0.50727
#SET FrameworkVersion=v2.0.50727
#SET FrameworkSDKDir=
#SET PATH=%FrameworkDir%;%FrameworkSDKDir%;%PATH%
#SET LANGDIR=EN
I have third party component installed in my Delphi, but I do not know if it influences anything. Anyone who can help me will be grateful.
the difference between the properties executed by jenkins and cmd are these:
it was resolved putting the paramether _EnvLibraryPath with my Delphi
LibraryPath parameter on msbuild call, example:
call "C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\bin\rsvars.bat"
msbuild "C:\Users\carlos.santos\Desktop\teste\Project1.dproj" /p:_EnvLibraryPath="C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\lib\EN;C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\lib"
There may be another cause for that same problem.
I have just experienced it and solved it.
In my case, it was related to the fact that I had another configuration besides Release and Debug, i.e. ReleaseConsumer.
My build command included specifying the configuration:
DoJenkinsTasks "US2D_GUI" "Config=ReleaseConsumer;Platform=Win64"
Now, I got that same error as mentioned above.
The cause is that it can't find the ReleaseConsumer folder with dcu files.
I solved it by creating, under c:\Program Files (x86)\Embarcadero\Studio\19.0\lib\win64\, a new folder releaseConsumer and copying all dcu files from release to it.
Run msbuild with the /v:diagnostic option, and you will see that none of the default environment paths are set:
Initial Properties:
___ResourcePath =
__ObjectPath =
__ResourcePath =
_EnvDCPOutput =
_EnvLibraryPath =
_EnvNamespace =
_EnvPackageOutput =
_ObjectPath =
_OutputDRCFiles = false
_ProjectFiles = #(DelphiCompile)
_ResolveGENTLBBindingsTarget =
This is because you are missing the %APPDATA%\CodeGear directory on your build server (under the user that is running the builds).
Particularly, you need the CodeGear\BDS\7.0\EnvOptions.proj settings file, which contains all the environment variables.
Put that in place and you'll see msbuild's diagnostics shows properties like this one:
Initial Properties:
___ResourcePath = C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\lib;\Imports;C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\Imports;C:\Users\Public\Documents\RAD Studio\7.0\Dcp;C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\include;C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\lib;C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\Lib\Indy10;

Windows Server 2003 call to secedit within a batch script generates "C:\Program" on system reboot

In executing
secedit /configure /db %~1\tomcat.sdb" /cfg %~1\2003.inf" /log %~1\dtomcat.log" /quiet
where
%~1 == C:\Program Files\myDirectory\mySubDirectory\mySuperSubDirectory
a file titled "C:\Program" is generated and within the file is the output for calling
secedit /?
I am curious as to why this is occuring because it makes it quite difficult to start certain services after an installation of a new product, for instance a PostGres windows service.
You appear to be missing quotes in a couple of places:
secedit /configure /db "%~1\tomcat.sdb" /cfg "%~1\2003.inf" /log "%~1\dtomcat.log" /quiet
^ ^ ^
You need to enclose the pathname in quotes:
"C:\Program Files\myDirectory\mySubDirectory\mySuperSubDirectory"
The space in "Program Files" is treated as a delimiter.

Erlang emakefile explain

I have an Emakefile that looks like:
%% --
%%
%% --
{'/Users/user/projects/custom_test/trunk/*',
[debug_info,
{outdir, "/Users/user/projects/custom_test/trunk/ebin"},
{i, "/Users/user/projects/custom_test/trunk/include/."}
]
}.
What is an explanation in layman's terms for what each item does in the list?
How do I run the emakefile so that I am able to compile it?
After compilation, how do I run that generated BEAM file?
1/ {"source files globbed", Options}
Here the options are :
debug_info add debug info for the debugger
{outdir, "/Users/user/projects/custom_test/trunk/ebin"} where should the output be written (the .beam files)
{i, "/Users/user/projects/custom_test/trunk/include/."} where to find the .hrl header files.
2/ erl -make
3/ erl -pa /Users/user/projects/custom_test/trunk/ebin starts a shell.
Find the module serving as an entry point in your application and call the functions :
module:start().
You can also run the code non interactively :
erl -noinput -noshell -pa /Users/user/projects/custom_test/trunk/ebin -s module start
For the Emakefile synax visit the man page
In the directory where the Emakefile is run erl -make to compile using the Emakefile
Simplest way to run would be to simply start an erlang shell in the same directory as the beam files with the command erl. Then run the code with module_name:function_name(). (including the dot).
