[Mingw-w64-public] clang and mingw-w64
Can someone who knows more about clang than I do help me out here? snow_xmas posted a problem report to the SF forum regarding using clang with mingw-W64. After a brief investigation, it became clear that the problem was that clang doesn't support one of the features of inline asm that gcc does. The hope was that the llvm people would choose to fix this, however it doesn't appear that's going to happen any time soon. The checkins that introduced this problem were done over a year ago and since then, it has not been possible to build mingw-w64 with clang. Because kai wants to continue to support clang, I have updated the code. However, I am no clang expert, so I don't feel like I have tested this sufficiently. And unfortunately, snow_xmas is no longer responding. The code is at http://www.LimeGreenSocks.com/intrin-impl.h (full file, not a patch). I realize that not everyone is an inline-asm expert, but in this case you really don't need to be. Building mingw-w64 with clang would be a good test, but I also have some test code for the various functions in intrin-impl.h if you want it. Without a clang expert to verify, I'm not going to be comfortable checking this in. dw -- Comprehensive Server Monitoring with Site24x7. Monitor 10 servers for $9/Month.

Hi Kai - A minor question about error numbers...

I found most (if not all) of them in include\c++\4.4.5\x86_64-w64-mingw32\bits\error_constants.h, but they are cmmented out... How should I proceed? Thanks, Ruben ... Well, those symbols you are seeing are in fact POSIX error numbers, which aren't present for native win32. So you have two chances here. First define those error-numbers (see here errno.h). The other variant is to modify Clang/LLVM in a way not to use those error-numbers. The latter is the correct way to solve it, the first is more a hack and can lead to other issues. I had one instance of a similar issuer with std::thread. mutex (the mutex header file) uses the value operation_not_permitted. Because this has a definition in error_constants.h that is commented out: //operation_not_permitted = EPERM, I assumed that it was perfectly appropriate and safe to fix the problem by uncommenting the line in question, thus defining operation_not_permitted. (Note, my problem is not fully analogous to Ruben's: for me, EPERM is defined, just not operation_not_permitted.) I hadn't realized that defining these error constants could cause issues. Is my current solution good and safe, or should I do something else? (In my case, it's just two lines in mutex that use just one constant, so just about any solution could be easily implemented.)
