While trying to install a build server I've run into a funny problem where all cygwin commands can be run from a DOS box but sometimes do not work when called from make. What's even more weird is some make targets, like 'clean', work and others, like 'all', do not.
Here's a representative makefile extract. The quoting has hosed the formatting but tabs are where they should be, trust me:
.PHONY: all
all: update_autoconstants
/usr/bin/rm -f $(OBJ_DIR)/myfile1.txt
rm -f $(OBJ_DIR)/myfile2.txt
.PHONY: clean
clean:
rm -f $(OBJ_DIR)/*.*
Notice that in 'all' one rm call has a full path and one has no path. Also notice that clean's rm call has no path.
To this the response to a 'make -C makefile all' is:
/usr/bin/rm -f ../../obj/myfile1.txt
rm -f ../../obj/myfile2.txt
make: rm: Command not found
make: *** [all] Error 127
ie. the full path works, the no-path does not. What then starts my head spinning is the 'clean' target in make with no path works fine. it's not just cygwin commands, make can't find the compiler either. It seems pretty clear that somewhere the path has been hosed, although the environment variable PATH is set, but only in make - this works fine from a DOS prompt.
C:\>cygpath --unix c:\programme\cygwin\bin\rm
/usr/bin/rm
The machine is running Windows Server 2003 German language in a virtual machine on VMWare ESX, the cygwin install was done yesterday, installed in c:\programme\cygwin\ and everything else is clean vanilla Windows installation.
Any ideas? Thanks in advance.
Not really so much of a solution as a workaround - we made all the makefiles use absolute paths to the exe files they need which is in any case a bit nicer than searching a path and taking what you find.
To perhaps save someone some Googling commands in cygwin's bin directory can best be called:
CYGWIN_EXE_PATH = /usr/bin
RM = $(CYGWIN_EXE_PATH)/rm.exe
.PHONY: clean
clean:
$(RM) -f $(OBJ_DIR)/*.*
And similarly files in the program files directory like this:
COMPILER_DIR = "$(PROGRAMFILES)/TASKING/c563 v3.6r1"
Hope that helps.
I've had the exact same thing.
rm not being found by make from within a makefile.
My workaround was to run the makefile from within bash. Previously I was just running make from a windows cmd box. This cured the problem for me, but created new issues. The permissions of some files that were created during the make had very odd permissions being set.

I'm trying to write (what I thought would be) a simple bash script that will:
run virtualenv to create a new environment at $1
activate the virtual environment
do some more stuff (install django, add django-admin.py to the virtualenv's path, etc.)
Step 1 works quite well, but I can't seem to activate the virtualenv. For those not familiar with virtualenv, it creates an activate file that activates the virtual environment. From the CLI, you run it using source
source $env_name/bin/activate
Where $env_name, obviously, is the name of the dir that the virtual env is installed in.
In my script, after creating the virtual environment, I store the path to the activate script like this:
activate="`pwd`/$ENV_NAME/bin/activate"
But when I call source "$activate", I get this:
/home/clawlor/bin/scripts/djangoenv: 20: source: not found
I know that $activate contains the correct path to the activate script, in fact I even test that a file is there before I call source. But source itself can't seem to find it. I've also tried running all of the steps manually in the CLI, where everything works fine.
In my research I found this script, which is similar to what I want but is also doing a lot of other things that I don't need, like storing all of the virtual environments in a ~/.virtualenv directory (or whatever is in $WORKON_HOME). But it seems to me that he is creating the path to activate, and calling source "$activate" in basically the same way I am.
Here is the script in its entirety:
#!/bin/sh
PYTHON_PATH=~/bin/python-2.6.1/bin/python
if [ $# = 1 ]
then
ENV_NAME="$1"
virtualenv -p $PYTHON_PATH --no-site-packages $ENV_NAME
activate="`pwd`/$ENV_NAME/bin/activate"
if [ ! -f "$activate" ]
then
echo "ERROR: activate not found at $activate"
return 1
fi
source "$activate"
else
echo 'Usage: djangoenv ENV_NAME'
fi
DISCLAIMER: My bash script-fu is pretty weak. I'm fairly comfortable at the CLI, but there may well be some extremely stupid reason this isn't working.
If you're writing a bash script, call it by name:
#!/bin/bash
/bin/sh is not guaranteed to be bash. This caused a ton of broken scripts in Ubuntu some years ago (IIRC).
The source builtin works just fine in bash; but you might as well just use dot like Norman suggested.
In the POSIX standard, which /bin/sh is supposed to respect, the command is . (a single dot), not source. The source command is a csh-ism that has been pulled into bash.
Try
. $env_name/bin/activate
Or if you must have non-POSIX bash-isms in your code, use #!/bin/bash.
In Ubuntu if you execute the script with sh scriptname.sh you get this problem.
Try executing the script with ./scriptname.sh instead.
best to add the full path of the file you intend to source.
eg
source ./.env instead of source .env
or source /var/www/html/site1/.env
I am trying to run a tool that uses Clang and LLVM. The tool name is cppgrep that is available with the docker. Please find it from the github repository - https://github.com/peter-can-talk/cppnow-2017. I have tried using Ubuntu 16.04 and 17.10, I got the same error as below:
root#522051d201d2:/home# ./cppgrep -help
./cppgrep: /usr/lib/x86_64-linux-gnu/libLLVM-4.0.so.1: version `LLVM_4.0' not found (required by ./cppgrep)
./cppgrep: /usr/lib/x86_64-linux-gnu/libclang-4.0.so.1: version `LLVM_4.0' not found (required by ./cppgrep)
root#522051d201d2:/home#
After some online search, I found that I had to setup the environment variable LD_LIBRARY_PATH. So as a first step I found the library files location in the docker, please find the output below:
root#522051d201d2:/home# find / -iname *libclang*.so*
/usr/lib/x86_64-linux-gnu/libclang-4.0.so
/usr/lib/x86_64-linux-gnu/libclang-4.0.so.1
/usr/lib/llvm-4.0/lib/libclang.so.1
/usr/lib/llvm-4.0/lib/libclang-4.0.so
/usr/lib/llvm-4.0/lib/libclang-4.0.0.so
/usr/lib/llvm-4.0/lib/libclang.so
/usr/lib/llvm-4.0/lib/libclang-4.0.so.1
/usr/lib/llvm-4.0/lib/clang/4.0.0/lib/linux/libclang_rt.dyndd-x86_64.so
/usr/lib/llvm-4.0/lib/clang/4.0.0/lib/linux/libclang_rt.asan-i686.so
/usr/lib/llvm-4.0/lib/clang/4.0.0/lib/linux/libclang_rt.asan-x86_64.so
/usr/lib/llvm-4.0/lib/clang/4.0.0/lib/linux/libclang_rt.asan-i386.so
After this step, I setup the LD_LIBRARY_PATH as follows:
root#522051d201d2:/home# echo $LD_LIBRARY_PATH
/usr/lib:/usr/lib/llvm-4.0/lib/:/usr/lib/x86_64-linux-gnu/
And lastly, I have exported it using the command export LD_LIBRARY_PATH. Now, if I try to run the cppgrep tool, I am still getting the same error. The command to test the tool after building the docker is as follows:
(1) cd into the cppgrep directory, like code/cppgrep,
(2) enter the docker container and mount the folder under /home:
$ docker run -it -v $PWD:/home clang
(3) run cppgrep using ./cppgrep 'x' test.cpp command.
It is suppossed to return functions and variables that has name x.
To replicate the error, after downloading and unzipping the file from github repository, build the docker container using $ docker build -t clang . command. Then follow 1,2,3 steps in the above paragraph.
After couple of days struggle, solved it!!
My initial assumption about the reason for the error is correct. The clang-llvm environment was not available to the cppgrep tool, but I made the mistake in the way of providing the environment information to the cppgrep tool.
The answer has two steps: (1) change the Makefile to point the correct location where you have installed the llvm, in my case, I change the following line in Makefile from HEADERS := -isystem /llvm/include/ to HEADERS := -isystem /usr/lib/llvm-4.0/include/. (2) You have to compile the file again by using the make command, just enter an empty space and save the cppgrep.cpp file before giving the command, otherwise, you will get a message as make: Nothing to be done for 'all'..
That is it, now you should be able to run the cppgrep tool by running ./cppgrep 'x' test.cpp or ./cppgrep -help. For using the other tools in this docker such as ast-dump, mccabe, etc. you have to follow the same above two steps before using them.
I am running make script(Execute Shell command option) inside a jenkins job.
The make script has rm -rf <directory name> shell command.
This command fails with error saying the Directory is not empty. Since script uses rm -rf it should work even if directory is not empty.
Not sure what is wrong here.
Any help around this will be much appreciated.
If your Jenkins job is executed on a Linux machine, this could b:
a permission issue.
a race condition issue (which is why deleting files first is a good idea. Then your rm -Rf will delete all the empty folders)
On Windows, check the full error message: there could be a resource preempted by the OS (used by another process).
You can first try and empty the directory and then delete the directory.
Try running the following command:
rm mydir/* mydir/.*
rmdir mydir
My vagrant VM box is super slow when I try to run my Rails app on it, and I'm guessing it's due to the shared folder problem.
I am trying to use rsync to circumvent the problem.
I installed Cygwin and necessary packages, put C:\cygwin64\bin; as PATH environment variable
and then changed my Vagrantfile to
config.vm.synced_folder ".", "/vagrant", type: "rsync"
When I run vagrant up, I Get this error message
$ vagrant up Bringing machine 'default' up with 'virtualbox'
provider... "rsync" could not be found on your PATH. Make sure that
rsync is properly installed on your system and available on the PATH.
What's going wrong here?
Thank you so much ... if there's any other way to run Vagrant VM box smoothly and faster on Windows 7, I would love to hear it too.
This turned out to be a bunch of brick-walls you have to circumvent when installing Rsync and setting it up correctly for Vagrant on Windows 7.
First of all, the error "rsync" could not be found on your PATH. Make sure that rsync is properly installed on your system and available on the PATH. was due to the fact that
1) Environment variable for Cygwin was placed in the latest order in the PATH, I changed it to the beginning of the path
2) During installation of Cygwin and Rsync, I installed individual "subpackages" instead of installing everything, thinking that it would be okay. Turns out I was wrong. I installed everything in the Admin package and Net package (not the SRC but just the bins), and then it started working. I suggest you set-up Cygwin again and really try to download everything if you see that error.
(I found these solutions through this post on SO cygwin + rsync)
Now, I could go into CMD and type rsync, and it would show up correctly. But then when I ran vagrant up it gave me another error saying
There was an error when attempting to rsync a synced folder. Please inspect the error message below for more info.

[sender=3.0.9]
I googled solution to this error and found this site. https://github.com/mitchellh/vagrant/issues/3230
Then there's a bug with Vagrant and cwrsync that I mentioned in #3086.
For now, just edit
C:\HashiCorp\Vagrant\embedded\gems\gems\vagrant-1.5.1\plugins\synced_folders\rsync\helper.rb
and add hostpath = "/cygdrive" + hostpath to line 74. It's a terrible
solution but quick and simple.
Editing that helper.rb file and adding hostpath at line 74 (just made some blank lines right there and pasted it in) and now it works perfectly!!!!
Rsync makes the shared folder soooooo much faster on Rails!!!! I think it is worth the pain of setting it up correctly. Try it!!
It's not clear from your message, but I think you installed rsync on your machine (the host), while it needs to be installed on the virtual machine you bringing up (the guest).
I was trying to set up a bash command in Terminal on a Mac.
The scripts run correctly when I execute them directly.
I set up symlinks in /usr/local/bin/ to the current location of the scripts. When I try to run it off the symlink, it doesn't work. I don't believe the issue is the $PATH, because pip, git, ipython all exist in this location. When I edit the $PATH setting, these fail.
Suggestions?
ls -l /usr/local/bin/foo and see where your symlink is actually pointing. Betcha it's broken.
If not, try running /usr/local/bin/foo. If that works, it was your PATH that's wrong, despite what you said in the OP.
The only other thing that would cause this behavior is if the script is reading $0 (its own name as executed). With a symlink, that will have a different value.
I found my own answer... The symlinks were created by an automated file which was gabbing my pwd. I was also using virtualenv, so to get it to work, I had to activate the virtualenv and be inside the folder that had the script that created the symlinks.
I install my commands in $HOME/bin instead of /usr/local/bin, but it does not matter much. As hinted in the comments, one question is whether the symlinks are set correctly.
Check which command the shell thinks you should execute: which command
Check that the link in /usr/local/bin points to the correct file (and has execute permission, etc):
ls -l /usr/local/bin/command
ls -lL /usr/local/bin/command
Check that the interpreter path in the shebang is correct:
file /usr/local/bin/command
Check that /usr/local/bin is actually on your PATH: echo $PATH
If none of that shows up a problem, show us the results of the commands above.
