Backport #6080

fails to define RUBY_FUNC_EXPORTED when compiled with clang

Added by john_firebaugh (John Firebaugh) over 12 years ago. Updated over 12 years ago.


Description

When compiling with clang, configure fails the checking for exported function attribute step and therefore does not generate a define for RUBY_FUNC_EXPORTED. This causes 3rd party gems such as ruby-debug-base to fail due to missing symbols.

Here is the relevant configure.log output:

I am not sure why configure decided that the first program, using __attribute__ ((visibility("default"))), failed. It successfully compiled and is correct.
