Several static libraries are leaking symbols #215

Open tmpsantos opened 8 years ago

Several of our static libraries are leaking symbols because we don't set the default visibility to hidden when building them. This is a problem because it can clash with system symbols when building Mapbox GL Native as a shared library. To some that I identified:

OpenSSL
libpng
sqlite
libuv
boost
geojson

Alternatively we could maintain an export symbol list on Mapbox GL Native.

Seems like this is the most failsafe and easily maintainable solution. But I'm certainly interested in trying to hide symbols in these packages at build time. The work needed would be to ensure that all packages support -fvisibility=hidden. Our geojson package does not yet, but the others should.
