Backport #6080

fails to define RUBY_FUNC_EXPORTED when compiled with clang

Added by john_firebaugh (John Firebaugh) almost 9 years ago. Updated almost 9 years ago.



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.
