Meson is new to me, but here is what I do in my configure.ac. The fragment below checks for various versions of GTK+ and glib and sets appropriate variables. You can also force gtk+ 2.x by passing --disable-gtk3 as a configure flag.
HAVE_GTK_VERSION3=false AC_ARG_ENABLE( gtk3, [ --disable-gtk3 Disable gtk+ 3.x and compile with gtk+ 2.x] , disable_gtk3=yes) if test "x$disable_gtk3" != "xyes" ; then echo -n "checking for GTK+ >= 3.0.0... " PKG_CHECK_EXISTS([gtk+-3.0 >= 3.0.0],[HAVE_GTK_VERSION3=true],[HAVE_GTK_VERSION3=false]) if test "x$HAVE_GTK_VERSION3" = "xfalse"; then echo "no" else PKG_CHECK_MODULES(GTK, gtk+-3.0 >= 3.0.0) fi else echo "Not checking for gtk+ 3.x" fi if test "x$HAVE_GTK_VERSION3" = "xfalse"; then echo -n "checking for GTK+ >= 2.4.0... " PKG_CHECK_MODULES(GTK, gtk+-2.0 >= 2.4.0) PKG_CHECK_EXISTS([gtk+-2.0 >= 2.16.0],[HAVE_GTK_VERSION216=true],[HAVE_GTK_VERSION216=false]) PKG_CHECK_EXISTS([gtk+-2.0 >= 2.6.0],[HAVE_GTK_VERSION206=true],[HAVE_GTK_VERSION206=false]) echo "- Compiling with gtk+ 2.x -" else GTK3_VERSION=`$PKG_CONFIG --modversion gtk+-3.0` echo "- Compiling with gtk+ version " $GTK3_VERSION " -" PKG_CHECK_EXISTS([gtk+-3.0 >= 3.10.0],[HAVE_GTK_VERSION310=true],[HAVE_GTK_VERSION310=false]) PKG_CHECK_EXISTS([gtk+-3.0 >= 3.11.0],[HAVE_GTK_VERSION311=true],[HAVE_GTK_VERSION311=false]) HAVE_GTK_VERSION216=true HAVE_GTK_VERSION206=true if test "$HAVE_GTK_VERSION310" = "true"; then if test "$HAVE_GTK_VERSION311" = "false"; then GTK310_WARN=true fi fi fi AC_SUBST(GTK_CFLAGS) AC_SUBST(GTK_LIBS) PKG_CHECK_EXISTS([glib-2.0 >= 2.14.0],[HAVE_GLIB_VERSION214=true],[HAVE_GLIB_VERSION214=false]) PKG_CHECK_EXISTS([glib-2.0 >= 2.4.0],[HAVE_GLIB_VERSION24=true],[HAVE_GLIB_VERSION24=false]) Regards, Gabriel. http://lives-video.com https://www.openhub.net/accounts/salsaman On Tue, Aug 22, 2017 at 5:07 PM, Link Dupont <l...@sub-pop.net> wrote: > Hi Igor, > > On Tue, 2017-08-22 at 15:48 -0400, Igor Korot wrote: > > Hi, ALL, > > I have setup to do my development for GTK+2 and GTK+3 on 2 different > > machines. > > My project is on GitHub and there is one codebase. > > > > What's the best way to set up Makefiles? > > You're going to find this is a matter of opinion.
