Manual talk:Enable TeX/problems


 * I have MediaWiki 1.6.1 running on one computer with full math support. One of the necessary steps was installing latex, etc. and creating two temporary files, images/math and images/tmp, with write permission.  That was once explained by a SuSE tutorial web page, which appears to have vanished.  I am now trying to install 1.10.1, had no problem compiling OCaml and texvc, and the command line tests run fine, both with vanilla equations and with \implies.


 * However, texvc generates the error Failed to parse (Can't write to or create math temp directory): I am certain I have the correct permissions on images/math and images/tmp, which are the two required folders for 1.6.1, but the problem remains.  I am doubtful that those are actually the paths texvc is trying to use.


 * There are two things that are inconsistent between the main page here and the version of texvc that came with 1.10.1.
 * The text mentions checking $wgTexvc. The command "grep -r wgTexvc *.php" executed in the root wiki folder gets zero hits.
 * The distributed files contain texvc_cgi.ml which contains hard-coded "tmppath" and "finalpath" values relating to someone's personal computer.
 * I tried changing those values to match my file structure and recompiling texvc, but the "make" file didn't recompile texvc_cgi.


 * I am willing to try variations on the texvc software, but I know nothing about OCaml, so I'm not even confident that I can comment out the intermediate file deletions without breaking something.


 * My guess, based on what I have seen here, is that texvc has been changed since this "problems" page was composed, and the linkage to the temporary and output folders has been broken.
