Errors when compiling with g++ 4.6

[Stuart A.]

I've encountered an error compiling STAF on Ubuntu 12.04 which comes with g++ version 4.6.3. When trying to compile STAF from source I got huge numbers of linker errors, along the lines of:

STAFSemService.cpp:(.text+0xf904): undefined reference to STAFEventSem::post()' STAFSemService.cpp:(.text+0xf91f): undefined reference toSTAFString::STAFString(char const*, unsigned int, STAFString::CodePageType)'
STAFSemService.cpp:(.text+0xf934): undefined reference to STAFCommandParseResult::optionTimes(STAFString const&)' STAFSemService.cpp:(.text+0xf943): undefined reference toSTAFString::~STAFString()'
STAFSemService.cpp:(.text+0xf9d2): undefined reference to STAFMutexSem::release()' STAFSemService.cpp:(.text+0xf9e8): undefined reference toSTAFThreadSafeDecrement'

The strange thing was that my cross-compilers didn't exhibit the error, only my native compiler. I discovered that my cross compilers were based on g++ 4.4, and when I reverted to the most recent g++ 4.4 build in the Ubuntu repository (as of writing, 4.4.7) the linker errors vanished.

I'm not certain what causes this issue, but I figgured you should be made aware that it's happening. This will hopefully also help others work out what's wrong with their STAF compilation in future.

Cheers,
Stuart

Thanks for reporting this. Some of the STAF code was written a long time ago and may need to be updated to avoid this error using the latest g++ version. I'll look into this.
