this is a "bug" in gcc 4.2 (and 4.3 I think). since gcc 4.4 unknown options such as "-Wno-unused-but-set-variable" give only a warning (and only if any other warning/error was found during compilation) see : http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28322 http://gcc.gnu.org/gcc-4.4/changes.html Specifically: > Unknown -Wno-* options are now silently ignored by GCC if no other > diagnostics are issued.

NB: I have the warning with gcc 4.4, triggered by another warning, namely: > FreeRDP-1.0/server/test/freerdp_server.c: In function ‘test_peer_load_icon’: > FreeRDP-1.0/server/test/freerdp_server.c:151: warning: ignoring return value > of ‘fgets’, declared with attribute warn_unused_result > FreeRDP-1.0/server/test/freerdp_server.c:153: warning: ignoring return value > of ‘fgets’, declared with attribute warn_unused_result > FreeRDP-1.0/server/test/freerdp_server.c:155: warning: ignoring return value > of ‘fgets’, declared with attribute warn_unused_result > FreeRDP-1.0/server/test/freerdp_server.c:158: warning: ignoring return value > of ‘fgets’, declared with attribute warn_unused_result I think it would be useful to have cmake add this option only if supported or if gcc > 4.3 Hope it helps Alexis ------------------------------------------------------------------------------ EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.
