Error 32512 (driver return code)

Question

I'm using XeTeX, Version 3.1415926-2.4-0.9998

I'm creating .tex file using PHP and storing it on linux server. [ex: abc.tex] Then creating .sh file with command to execute *.tex file using XeLaTeX [ex: abc.sh]

sample content of abc.sh

/usr/local/texlive/2012/bin/x86_64-linux/xelatex abc.tex

If i execute abc.sh on linux command prompt, required PDF is getting generated. But, If i execute abc.sh from apache webserver via php, it's giving error as :

Error 32512 (driver return code) generating output;
file abc.pdf may not be valid.

Note: There is NO PDF File generated.

Can you please suggest any pointers to solve this?

Answer 1

Finally it got executed. DANGER part is that, still I don't know reason. I suspect it may be due to some path issue.

Instead of executing tex file using xelatex, i complied it with latex & then with dvips and finally converted PDF using ps2pdf

NOTE: it's getting executed via webserver using PHP

Answer 2

Here is a working way to execute latex from PHP. The point is that functions as exec, shell_exec, passthru, etc. get no or a vary limited PATH variable. However, latex, pdflatex and others use the path variable to call other programs. We therefore need to set the path appropriately, for example as follows:

passthru('PATH=/usr/bin:$PATH pdflatex file.tex');

Also note that your webserver user (typically www-data or apache) should have the necessary packages installed; this may not be the case if you're using local tlmgr stores.
