Re: [sigc] Build failed

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

If libsigc++ can't be built on Mac OS X I'd like to know why, and what can be done about it.
The error messages says that no definition is available for
std::basic_ostream<>& std::operator<<(std::basic_ostream<>&, const std::basic_string<>&).
I thought #include <iostream> should fix that. Is any other include file necessary in OS X?
You can try with removing the SIGC_USING_STD macros. They are unnecessary since many years. But I'd be surprised if it fixes your problem.

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:

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!
