Re: [Tuxmath-devel] tuxmath fails to compile without sdlttf

Hi Volker, Tasos,

I removed the unneeded T4K_COMMON prefix from the vars as suggested.
For the moment I still have separate DEP_LIBS and DEP_LIBS_PRIVATE,
but I can simplify that later.

The update is in t4k_common's git repo:

git clone git://git.debian.org/git/tux4kids/t4kcommon.git

Thanks - I've attached those files.  I can think of a few things I
haven't yet addressed:
1. DEP_LIBS_PRIVATE as of yet is just contains all the secondary
dependencies for all the non- *.pc libs.  It was not created very
carefully, basically grabbed from the args passed to gcc at the end of
the regular linux non-static build process, after which I eliminated
duplicates and the primary dependencies.  So it might possibly have
some things in there that wouldn't be needed if some of the optional
libs are deselected.  I think I should make the lib checks in
configure.ac mimic the pkg-config process more closely, adding to this
var as each library is located.
2. As you suggested, the lib checks use a two stage procedure, first
trying PKG_CHECK_MODULES, then AC_CHECK_LIB if needed.  Once the lib
is detected, by either method, I add the library name to DEP_LIBS (for
the ones I know have *.pc files).  But this might result in an error
if the fall-back to AC_CHECK_LIB was required.  So I think perhaps
DEP_LIBS should be updated in the "action_if_found" part of
PKG_CHECK_MODULES.

I will look at some *.pc.in files from other projects, as you
suggested, for working examples I can follow.

Thanks,

David
