As far as I know the code should be something like https://cgit.freedesktop.org/spice/spice-gtk/commit/?id=f697933524b19186cb078b5fca43f748fd68cf9f replacing LIBS and CFLAGS temporarily before doing the function check but it's quite ugly (well, lot of configure code looks ugly to me...) > > > > > if test "x$have_lz4" = "xyes"; then > > > AC_DEFINE(USE_LZ4, [1], [Define to build with lz4 > > > support]) > > > elif test "x$enable_lz4" = "xyes"; then > > > - AC_MSG_ERROR([lz4 support requested but liblz4 could not > > > be found]) > > > + AC_MSG_ERROR([lz4 support requested but liblz4 >= 129 > > > could not be > > > found]) > > > fi > > > fi > > > AM_CONDITIONAL(HAVE_LZ4, test "x$have_lz4" = "xyes") > > > > Beside the cross compilation issue patch works for me. > > Frediano _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/spice-devel
