No, imlib doesn't really need to leave a text file around.. Just duplicate the
checks Imlib performs in your configure.in, and your program will magically link
against the same libs imlib used...
Example, from eMusic's configure.in, only relevant parts included:
AC_PATH_X
AC_PATH_XTRA
LIBS="$LIBS $X_LIBS -lX11 -lXext $X_EXTRA_LIBS"
GRLIBS="-L/usr/X11R6/lib -L/usr/local/lib -L/usr/X11/lib -L/usr/lib/
-L/usr/local/X11R6/lib -L/usr/local/X11/lib -L/usr/openwin/lib -L/lib -lc"
AC_CHECK_LIB(m, sin, GRLIBS="$GRLIBS -lm",
echo "ERROR: You NEED to fix your system 'cuz -lm wasn't found"; \
exit, $GRLIBS)
AC_CHECK_LIB(png, png_get_valid, GRLIBS="$GRLIBS -lpng -lz", ,
-L/usr/lib -L/lib -L/usr/X11R6/lib -L/usr/X11/lib \
-L/usr/local/lib -L/usr/local/X11R6/lib -L/usr/local/X11/lib \
-L/usr/openwin/lib -lc -lm -lz)
AC_CHECK_LIB(jpeg, jpeg_read_scanlines, GRLIBS="$GRLIBS -ljpeg", ,
-L/usr/lib -L/lib -L/usr/X11R6/lib -L/usr/X11/lib \
-L/usr/local/lib -L/usr/local/X11R6/lib -L/usr/local/X11/lib \
-L/usr/openwin/lib -lc -lm)
AC_CHECK_LIB(tiff, TIFFOpen, GRLIBS="$GRLIBS -ltiff", ,
-L/usr/lib -L/lib -L/usr/X11R6/lib -L/usr/X11/lib \
-L/usr/local/lib -L/usr/local/X11R6/lib -L/usr/local/X11/lib \
-L/usr/openwin/lib -lc -lm)
AC_CHECK_LIB(gif, DGifOpenFileName, GRLIBS="$GRLIBS -lgif", ,
-L/usr/lib -L/lib -L/usr/X11R6/lib -L/usr/X11/lib \
-L/usr/local/lib -L/usr/local/X11R6/lib -L/usr/local/X11/lib \
-L/usr/openwin/lib -lc -lm)
AC_CHECK_LIB(Imlib, Imlib_init, GRLIBS="$GRLIBS -lImlib", echo "ERROR: you need
Imlib to use eMusic"; exit, $GRLIBS)
AC_CHECK_LIB(Fnlib, Fnlib_init, GRLIBS="$GRLIBS -lFnlib", echo "ERROR: you need
Fnlib to use eMusic"; exit, $GRLIBS)
AC_CHECK_LIB(esd, esd_play_stream, GRLIBS="$GRLIBS -lesd", echo "ERROR: you
need EsounD to use eMusic"; exit, $GRLIBS)
LIBS="$LIBS $GRLIBS"
The only thing this doesn't check for is zlib.. guess I should make it do
that... but the above SHOULD work for almost any system..
