Bug #10656

mkmf have_func fails if Ruby is compiled with static libruby

Third Party's Issue
Target version:


If Ruby is compiled with static libruby, then mkmf have_func calls will fail. This is because have_func tries to compile a binary, passing -lruby-static to the compiler. However this fails because binary also needs to be linked to a bunch of libraries that ruby-static.a depends on, such as -lm, -lrt, -ldl etc.

See Phusion Passenger bug 1314 comment 68140592 for details and for an mkmf.log. Users who have a static libruby are unable to use the Phusion Passenger native extension, because a have_func('rb_thread_call_without_gvl') failed where it should have succeeded.

Hm, I see. We clear $LIBS in order to fix, but that may be interfering. Let me investigate this further.

You were right. I've fixed this in Passenger 4.0.57. Thanks Nobuyoshi.
