Hello,

After generating a tex file through Matlab, I want to compile the tex to PDF (still within Matlab). For this purpose I have the line below :

system( [ 'latex2pdf ', texPath ] ); % texPath is the full path to my tex file.

The actual command line works when I copy it to my terminal (bash on Ubuntu), but in Matlab it gives me the following error(s) :

xelatex: /usr/local/MATLAB/R2014a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by xelatex)

xelatex exited with errors:

LaTeX::Driver::FilterProgram::execute('LaTeX::Driver::FilterProgram', 'format', 'pdf') called at /usr/bin/latex2pdf line 33

I've read somewhere on this forum that the Matlab "environment" can be different than the shell's because my profile is not sourced (I don't really understand what that means to be frank), so I followed advice givien in the link below and added the following line to MATLABROOT/bin/matlab :

source $HOME/.profile

http://www.mathworks.com/matlabcentral/newsreader/view_thread/255609#931372

I then restarted Matlab, hoping to give it the same "environment" as my shell, but I still get the same error.

FYI, I also get errors using the command pdflatex :

pdflatex: /usr/local/MATLAB/R2014a/bin/glnxa64/libtiff.so.5: no version information available (required by /usr/lib/x86_64-linux-gnu/libpoppler.so.52)
pdflatex: /usr/local/MATLAB/R2014a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /usr/lib/x86_64-linux-gnu/libpoppler.so.52)

However, other basic commands (ls, dir, ...) work fine.

Finally, I created a shell script that launched latex2pdf and called my script from Matlab, but got the same error.

I've spent hours on this super frustrating problem (such a small step away from my result it seems silly to give up and launch the command in a separate terminal), any help will be much appreciated !

Thanks,

Tepp

PS : sorry for the double post as I started a thread in Newsgroup before noticing that it was probably best to post in Answers (much better interface for formatting code, etc.). I will update both posts with crossreferences as soon as it becomes relevant.

tepp yogi's "Answer" moved here:

Perhaps, if no one is familiar with using latex2pdf or pdflatex from Matlab, someone can suggest to me an alternative solution ?

Thanks,

Tepp.

Hello,

I finally got a workaround sort of working (don't like it but it's the best I've got to so far) : I created a script to launch Matlab.

Here's what it looks like :

#!/bin/sh
cd ~
LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libstdc++.so.6" matlab

If anyone has a better suggestion feel free to post :)

Thanks,

Tepp

Actually, for this script to be launchable through Unity Launcher on ubuntu I adapted the script to the following so that the window would stay open after the command executes in terminal :

#!/bin/sh
cd ~
export LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libstdc++.so.6"
matlab -desktop &

Remove that "source" that you added.

Go to a Terminal window (Terminal is in /Applications/Utilities). When you are there give the command

otool -L latex2pdf

and look to see which directory it finds libstdc++* in.

And then have a look at http://uk.mathworks.com/matlabcentral/answers/230535-wrong-java-version-when-calling-via-system#answer_186650

Dear Walter,

Thanks so much for your help. You are right, when I run the command from my terminal it gives different information than when I run it from Matlab :

terminal :

>> ldd /usr/bin/pdflatex | cat | grep libstdc++
   libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9292172000)

matlab :

system( 'ldd /usr/bin/pdflatex | cat | grep libstdc++' )
   libstdc++.so.6 => /usr/local/MATLAB/R2014a/sys/os/glnxa64/libstdc++.so.6 (0x00007fc0d3ad0000)

Before calling this command I undid the "source" as you suggested and restarted Matlab. My PATH, DYLD_FRAMEWORK_PATH and DYLD_LIBRARY_PATH environment variables had their expected values in Matlab (i.e. essentially similar to their terminal counterparts, except for unrelated tools I installed in my path). I also used ldd instead of otool since otool seems to be Mac only and I am using Ubuntu.

NEXT STEPS : To get pdflatex to work, I believe I now would need to understand how to make pdflatex use the "original" libstdc++ library (the one in /usr/lib/x86_64-linux-gnu) instead of Matlab's ? I will go on searching but if you have any more pointers for me they will be much appreciated :)

Thanks,

Tepp.

I also tried modifying the matlab command by including the export before launch, that didn't work either.

Hello!

I was reading the post because i had the same problem. The workarround that i did was to rename the file sys/os/glnxa64/libstdc++.so.6 to sys/os/glnxa64/libstdc++.so.6.resp and make a symbolic link to the file of the host operating system:

user@host:/my/MATLABDIR/sys/os/glnxa64$ sudo mv libstdc++.so.6 libstdc++.so.6.res
user@host:/my/MATLABDIR/sys/os/glnxa64$ sudo ln -s /usr/lib/libstdc++.so.6

After that just do:

system('pdflatex test.tex')

And remember to erase the link and rollback the name of the file. It's not an elegant solution but at least it works.

I just ran into this problem as well. I wanted a solution that does not require any changes to matlab startup and would work across linux machines without modifying anything outside of the script.

For the bash syntax on linux, the following works for me by adding the system library path to the environment just for the call to the pdflatex command:

system('LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:LD_LIBRARY_PATH; export LD_LIBRARY_PATH; pdflatex filename.tex')

You may need to change the /usr/lib/x86_64-linux-gnu/ part to match your system, and you can determine the correct path using the ldd command posted above. Also, the matlab docs on setenv show how to set the path if your system uses sh instead of bash.

Actually setenv is for csh rather than sh. But sh did not support the "export" command. Also you missed substituting in the current value.

The sh version should be:

system('LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH export LD_LIBRARY_PATH; pdflatex filename.tex')

That will also work for ksh and bash, but for ksh and bash you can also use

system('export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH; pdflatex filename.tex')
