Build fails with libpng 1.4.x
|Reported by:||vog||Owned by:|
On a system with libpng 1.4.x, a "configure --with-libpng=sys" fails with:
checking for png.h > 0.90...
checking for png.h... yes
checking for png_check_sig in -lpng... no
configure: error: system png library not found or too old! Use --with-libpng=builtin to use built-in version
It checks for the deprecated function png_check_sig(). Since that function isn't used by wxWidgets anyway, checking instead for png_sig_cmp() solves the problem.
The attached patch does exactly that. Note that it changes just configure.ac, so the configure script needs to be recreated after applying the patch.
