Instructions to create tex4ht binaries on KUbuntu/Ubuntu/Debian 64-bit (aka amd64) systems Rob Beezer, firstname.lastname@example.org, http://buzzard.ups.edu 2009/01/31 Tested on a Kubuntu 8.10 amd64 stock installation (presumably Debian is similar and Ubuntu identical) 2010/08/23 libpathsea upgraded in 10.04, forced recompile 2010/12/07 verified with a rebuild of SVN 66 source a. There are three Ubuntu/Debian packages you may need and not have installed. If you are unsure if you have them, just try installing them. If you do have any of them, then you will get a warning and a chance to retry after omitting the request for the installed package. gcc: the standard C compiler libkpathsea4: library for TeX path searching, part of the texlive distribution provides files like /usr/lib/libkpathsea.so.4.0.0 libkpathsea-dev: development files for libkpathsea provides numerous header files (*.h) in /usr/include/kpathsea To install, execute (as root): apt-get install gcc libkpathsea4 libkpathsea-dev b. Install tex4ht, or unpack the latest distribution into a scratch directory (/tmp, say) c. Move/copy src/t4ht.c, src/tex4ht.c into a working directory (/tmp/tex4ht, say) (htcmd.c is not necessary or needed and can be ignored) d. Within your working directory, issue the following two commands gcc -O2 -DKPATHSEA -I/usr/include -L/usr/lib -o t4ht t4ht.c -DHAVE_DIRENT_H -lkpathsea gcc -O2 -DKPATHSEA -I/usr/include -L/usr/lib -o tex4ht tex4ht.c -DHAVE_DIRENT_H -lkpathsea (2010/08/23 Question: Is there a way to link dynamically to libkpathsea, so upgrades of kpathsea do not require recompiling?) e. Determine where you need/want to place these executables. If your setup is otherwise complete, then the command which t4ht might provide the answer. The locate database is typically regenerated automatically overnight, and so locate t4ht might also indicate the location sometime after installation. The find command is another possibility. From your working directory, move/copy the files t4ht, tex4ht to the place you want them to be. If you end up with several versions of these executables, a command like file t4ht will tell you if one is 32-bit or 64-bit.
