I do not believe your diagnosis is correct (but I am not at keyboard to check). The configure visibility stuff turns on 2 different things:
- visibility compiler attributes - compiler cli flags (fvisibility) With your sed, u only disabled the cli options, whichight be redundant anyway. But the vis attrs were left on, and therefore the lib symbols might not have been visible properly...? That's a guess. The fact that u did disable vis and it works means that when all vis stuff is properly disabled, it works fine. So I think the real issue is why configure might be getting your visibility tests wrong...? Please send your configure stdout/stderr and config.log - we can have a look. Sent from my phone.
