have a cgi-script which generates a *.tex file based on inputs from the browser. i would like to generate a pdf and download it.

however the command doesnt execute and i get a fail message

if lualatex -interaction batchmode 3.tex                                                                                                                                 
          echo "fail"
          exit 2

the 3.tex file is perfect and lualtex executes when directly executed from terminal.

i have used this also but could get it too work

kindly help

  • is luatex in the PATH available in your cgi-bin environment? – David Carlisle Oct 22 '16 at 19:02

    stick echo $PATH and type luaflatex into the script and see what comes out, or simply use luatex by its full path /usr/local/texlive/20..../bin/lualatex or whatever is allowed in your cgi environment, if the web server runs off a virtual root is tex even installed? – David Carlisle Oct 22 '16 at 19:10
  • thank you sir, it started working after adding the full path. could you please guide as to how to add it to the PATH available in your cgi-bin environment – user1869714 Oct 22 '16 at 19:18

    just put export PATH=/usr/local./txliv/whevere/it/is:$PATH as teh first line to add the texlive bin to the path – David Carlisle Oct 22 '16 at 20:44

cgi-bin jobs do not run in your usual user enviromment so you may need to access luatex by full path

/usr/local/texlive/2016/bin/whatever/lualatex 3.tex

or add the bin directory to your path

export PATH=/usr/local/texlive/2016/bin/whatever:$PATH

lualatex 3.tex
