Hi, I have a problem when using the boost::program::options library under cygwin in conjunction with building a application which I compile with the "-mno-cygwin -mwindows" options.
I get a "undefined reference error to _environ" at link time. I guess the problem arised because boost libraries (version 1.33) was built as an cygwin application and I want build a pure windows application with this library. On the other hand I already linked another boost library (boost::filesystem) against my application and got no error ?! I now built the boost libraries under mingw by myself and got a boost_program_options-gcc-1_33.dll and boost_program_options-gcc-mt-1_33.lib. I replaced the cygwin libboost_program_options-gcc-mt-s.a with my boost_program_options-gcc-mt-1_33.lib (renamed boost_program_options-gcc-mt-1_33.lib to libboost_program_options-gcc-mt-s.a), copied the dll to C:\WINDOWS\system32 and it worked ! This is of course nice but can someone give an explanation ?
