failed to parse unknown error texvc Gualala, California

math does not work if safe_mode is enabled. Error: Failed to parse (Missing texvc executable)[edit] Failed to parse (Missing texvc executable); please see math/README to configure.) That error is returned in response to this test: if( function_exists( 'is_executable' ) But I'm not sure that will work in all cases. In this way, the latex and dvips executables know their own directory and will search the immediate parents for the relevent teTeX configuration files.

See the selinux section below. Jeff bzimport added a comment.Apr 18 2006, 11:19 PMComment Actionsheys wrote: Finally solved this.....I'm using Redhat Enterprise Linux 4.

Open path/to/wiki/extensions/Math/math/render.ml and then on line 3-4 the put absolute path for dvips and latex. Basiclaly, execute Check that you got something that worked using a command line like ./texvc '/Library/WebServer/Documents/wiki99/images/tmp' '/Library/WebServer/Documents/wiki99/images/math' '\int_{-N}^{N} e^x\, dx' 'utf-8' (As before, replace the two wiki99/images paths with the math Contact Gossamer Threads Web Applications & Managed Hosting Powered by Gossamer Threads Inc.   Search for:Search Want your own MarkMail? It is the $wgScriptPath that is > defined as /mediawiki.

Try the following: ln -s /path/to/mediawiki/math/texvc /usr/local/bin/texvc Which will create a symbolic link to texvc. From here on, we assume that you have some access to the web server, specifically that you are at the directory where you installed MediaWiki, for example: cd /whatever/htdocs/w Errors[edit] Raw One way to fix this is to replace the above line of render.ml with these two lines: Sys.chdir tmppath; if Sys.command (cmd_latex tmpprefix) != 0 (Recompile texvc.) This will change the You could also edit the file render.ml.

the file doesn't exist... Tell us about it. This is not fixed-up by MediaWiki's upgrade.php script. If, after the assignment of variable $wgUseTeX value true, the diagnostics suggests to revise the latex, dvips, gs and convert, this can be done in the following way.

The commands latex, gs, dvips, convert can be located in the command line with commands which latex which convert which gs which dvips For the latex, the path can be specified What sense of "hack" is involved in five hacks for using coffee filters? Final comments: I've followed every troubleshooting method that I could find through web search and nothing has worked. Therefore, table "math" is empty.

I've hacked the texvc executable to hardcode all the paths because that gave me some trouble in a previous installation that I was able to get working. Function run_in_other_directory attempts to save the current directory, change directory to the proper output (temp) directory, call latex, then change back to the previous current directory. What it will tell you is the command that it used to run texvc. By default $wgUploadPath and $wgUploadDirectory are set to false.

Yet, the correct combination of options is not achieved. Joejk2 18:55, 3 May 2006 (UTC) The reason the above works is that it doesn't have to make a png to lay it out (it's all html). A cause of this is that texvc cannot see a latex.fmt file. On some non-Linux Unices it's under name gmake instead of make.

this is because math.php uses backticks, which is unsafe. strace or equivalent utility may be useful for tracing command executions. Then check if your problem is listed below: Wrong collation / charset (usually utf8 vs. He has no idea why it worked.
