I'm new to this list and to Boost. I'm interested in using Boost to wrap C++ objects in Python. The environment is Solaris 10, x86. I did the following:

...

Caleb and Dave, Thanks so much for your replies! I didn't see them until this weekend, so I hadn't responded sooner. Being unable to get Boost to compile, and needing to get some Python extensions working right away, I started using SWIG, which so far has met my basic needs. What version of Solaris and gcc are you using? Solaris 10/x86 gcc 3.4.3 Can you include

*actual* error messages with actual filenames and line numbers to help diagnose the problem?

I attached the full output from bjam. I'm not sure when I will be able to get back to Boost. It may depend on whether I run into SWIG limitations. Regards, Chris

Not sure if it helps, but the compiler seems to be complaining about this line:

BOOST_STATIC_ASSERT(BOOST_PYTHON_OFFSETOF(rvalue_from_python_storage<T>,stage1) == 0);

Where Solaris appears to define offsetof() in /usr/include/iso/stddef_iso.h as:

#if __cplusplus >= 199711L #define offsetof(s, m) (std::size_t)(&(((s *)0)->m)) #else #define offsetof(s, m) (size_t)(&(((s *)0)->m)) #endif

Not sure if there is much that I can do to help aside from saying "it works for me" using gcc 4.1.1.

Thanks for looking at this and the info, Caleb. I'll see about about upgrading gcc and giving it another try. - Chris
