[Mingw-cross-env-list] sdl_ttf not detected by configure.ac because needs freetype

[David Bruce]

Hi Volker,

If I build tuxtype using sdl_ttf rather than sdl_pango (i.e.
"./configure --without-sdlpango"), the build fails to detect sdl_ttf.
Upon looking in config.log, the problem is that the test program
generated by configure does not link to freetype.  As a test, I put
"LIBS=-lfreetype $LIBS" into tuxtype's configure.ac just before the
check for sdl_ttf and the build succeeds. I don't have a Windows
machine handy to see if the resultant program works right now.

So, basically, when I link tuxtype to sdl_ttf, tuxtype doesn't get
also linked to freetype.  At first glance, I don't see how this needs
to be specified within mingw-cross-env or I would try to create a
patch.

Thanks for any help,

David

Below are some details of the failed build:

>From configure.ac:

dnl We only use SDL_ttf if SDL_Pango not available:
--------------------------------------

if [test "x$with_sdlpango" = xno]; then
AC_CHECK_LIB([SDL_ttf],
             [TTF_Init],
             ,
             [AC_MSG_ERROR([SDL_ttf not found!
http://www.libsdl.org/projects/SDL_ttf])])
