Re: [sigc] Build failed

The failure was in one of the examples, so you could just comment it out in the makefile.  If you want to try to fix the example, I'd start by removing the USING macros.

Hi,

I'm trying to compile libsigc++ on a mac os x 10.8 (Mountain Lion). I have the error below I can't find an issue to. Here is the trace:

libsigcpp build failed

I'm using i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00).

You could take a look a this page for more information: http://stackoverflow.com/questions/15233978/building-libsigc-fails-stdbasic-ostream-explicit-instantiation .

Many thanks!
