Currently I have the following code to build wxWidgets program with autotools: configure.ac: WX_CPP="`wx-config --cppflags`" AC_SUBST(WX_CPP) WX_LIBS="`wx-config --libs`" AC_SUBST(WX_LIBS) Makefile.am: AM_CXXFLAGS = $(WX_CPP) program_LDADD = $(WX_LIBS) This works fine. Now I want to use WX_CPP and WX_LIBS as configure script parameters, allowing to change default values. I need to run the configure script by the following way: ./configure WX_CPP="`cpp-flags-program`" WX_LIBS="`lib-flags-program`" or: ./configure WX_CPP="compiler flags..." WX_LIBS="linker flags..." This doesn't work, because AC_SUBST is done when configure script is generated, and not when it is executed. Is there some way to get it working? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
