Boost spews excessive warnings

[jdm]

It can be frustrating to find actual errors among all of the boost output. I don't know if this is just an OSX 10.6.8, gcc 4.2.1 thing (since I see mentions of CLANG in the warnings), but it would be nice to get this cleaned up.

I get a few Boost warnings even on Linux with modern GCC, though not as many. The way to find errors is to run make again if it fails before linking everything, it will resume with the last step before the error :)

[historic_bruno]

Compiling with -isystem/path/to/boost instead of -I/path/to/boost suppresses the warnings. I'm not sure there's any better solution for GCC 4.2. Let's see if premake can do that, assuming there are no negative consequences.

Some of the warnings are already reported on Boost Trac, where they seem to linger for months/years :( I'll try to report the others, so there's a chance Boost devs will fix them, eventually.

Edit: Reported to Boost devs: ​#6140, ​#6142, ​#6522, not sure about the BOOST_CLANG warning, it might have been fixed recently.

Replying to historic_bruno:

​#6522

Should be fixed in Boost 1.49.

In 13172:

Suppresses noisy Boost header warnings on OS X by including them as system headers, refs #1076.
Bumps default SDK in build-osx-bundle.sh to 10.7 (newer Xcode doesn't include 10.6).
Fixes using xml2-config from SDK when needed.
Fixes more linker warnings about symbol visibility by compiling libs with fvisibility=hidden.
Updates some comments in the build scripts.
