Why aren't the soil2 flags showing up in my g++ > invocation? You do AM_CXXFLAGS = @gllibs_CFLAGS@ -Wall -v AM_LDFLAGS = @gllibs_LIBS@ -lm and PKG_CHECK_MODULES([gllibs], [gl glew glfw3 >= 3.0]) PKG_CHECK_MODULES([soil2], [soil2]) i.e. you use the result of the gllibs check but not the result of the soil2 check. It should rather be AM_CXXFLAGS = @gllibs_CFLAGS@ @soil2_CFLAGS@ -Wall -v AM_LDFLAGS = @gllibs_LIBS@ @soil2_CFLAGS@ -lm _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
