Re: [Boost-users] [extension] conflict with boost::optional

Thanks! That looks like it ought to fix it. I updated the Sandbox with the proposed fix, and was able to successfully build and run the tests and examples on MSVC 9 and GCC 4. Please let me know if that fixes the issue for MSVC 7.1. Jeremy On Sat, Apr 19, 2008 at 9:20 AM, Niels Dekker - mail address until 2008-12-31 wrote:

Please add the command line option /P to your build - this will output the preprocessed version of your file test_extension_and_optional.cpp. Then send this to me - I might be able to figure out what is going on. It looks like one of the preprocessor macros used by Boost.PreProcessor isn't working

It seems to me that the compile error isn't caused by Boost.PreProcessor. Actually I think I've found a workaround: Explicitly qualify the shared_library::get member function call in extension/convenience.hpp (line 29), (by adding the class name, "shared_library::") and the MSVC 7.1 error message disappears!

HTH, Niels
