[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

Erik Bray added the comment: I'm also inclined to agree that the buggy code (and it *is* buggy even if it was meant to fix something originally) should be removed outright. Nobody can point to a real world issue that it fixes anymore, yet we can point to real world consequences caused by

[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

Dan Mick added the comment: So the original author of the code says it's "likely no longer relevant", and it's clearly wrong, but no one has touched this in six years? Even moving the "linker[i] = self.compiler_cxx[i]" inside the if that checks for "env" would *still* limit the exposure of

[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

Ronald Oussoren added the comment: I don't recall exactly why the universal build support is done the way it is, adding it is too long ago. The reason is likely no longer relevant with any reasonably up-to-date toolset. The patch was created around the time x86 support was added to OSX and

[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

Joshua J Cogliati added the comment: I looked and the autoconf variable for the c++ linker is CXXLINK, so I think the proper way to fix this would be to change sysconfig.py to look at both CXXFLAGS and CXXLINK, and create those and use it to define a cxxlink variable, and only if they are

Joshua J Cogliati added the comment: Let me try and explain what is trying to be done in the original code, what the fix was, and then discuss some possible better solutions. Original code: if target_lang == c++ and self.compiler_cxx: linker[0] = self.compiler_cxx[0] Current code: if

[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

Joshua J Cogliati added the comment: Looking at the patch (3078fdb7cf3d for Issue1488098) it has: if target_lang == c++ and self.compiler_cxx: -linker[0] = self.compiler_cxx[0] One possibility is that that the problem was: linker[0] = self.compiler_cxx[0]

[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

Joshua J Cogliati added the comment: Does the patch fix things on Mac OS X and Linux? So far as I can tell, the code in question is to do something so that CXX variables like: export CXX=env BAR=FOO g++ work better. However, it is broken for that case, and since it has been broken since at

Ned Deily added the comment: The code in question was added a long time ago by Ronald as part of the initial OS X universal build support (3078fdb7cf3d for Issue1488098). I'm not exactly sure what problem it was trying to solve ao I'm not sure that it's 100% safe to totally remove rather
