Hello autoconf gurus! I am trying to write some autotools support for installing a latex package. On CTAN I found some autoconf macros (which I had to modify a bit) which I use to find for example latex(1) and pdflatex(1). So far so good. This CTAN package also has a macro to find the path to the tex installation, AC_TEXMF_PATH. This finds the correct path for me at /usr/share/texmf-dist. Now I want to put this as the default prefix so that configure will "do the right thing" by default, but this is where I fail.
This is my configure.ac: ---------------------------------------- AC_INIT([package], [0.1], [blah]) AC_PREREQ([2.60]) AC_CONFIG_MACRO_DIR([m4]) AM_INIT_AUTOMAKE([foreign]) AC_PROG_INSTALL AC_PROG_LATEX AC_PROG_KPSEWHICH AC_PROG_PDFLATEX AC_TEXMF_PATH AC_PREFIX_DEFAULT([$texmfpath]) AC_MSG_NOTICE([$texmfpath]) AC_CONFIG_FILES(Makefile) AC_OUTPUT ---------------------------------------- AC_TEXMF_PATH exports `texmfpath' and does AC_SUBST on it. (You can find all the macros here: https://www.ctan.org/tex-archive/support/autoconf) The problem is with the AC_PREFIX_DEFAULT. It sets the default prefix to empty. But the AC_MSG_NOTICE macro on the line below prints the correct path! So somehow $texmfpath is expanded to the correct value by AC_MSG_NOTICE, but it is expanded to nothing on the line above. If I do AC_PREFIX_DEFAULT(["some_path"]) then the default prefix is correctly set to "some_path". Is it not possible to set the default prefix in this way? What other good ways are there to set the default prefix to something discovered at configure time? I'm not subscribed to the list so if somebody answers, please keep me on cc :) Regards, Joakim _______________________________________________ Autoconf mailing list Autoconf@gnu.org https://lists.gnu.org/mailman/listinfo/autoconf
