Salutations. I right now use CXX_STANDARD and CXX_STANDARD_LIBRARY for some test projects since I want to utilize smart pointers. As I am on a Mac, my preferred IDE is Xcode (sometimes called XCode), so I generate Xcode targets by default. I've noticed, however, that whenever I use CXX_STANDARD and its companions, it places the -std=gnu++11 (or equivalent) calls in the OTHER_CPLUSPLUSFLAGS attribute instead of the CLANG_CXX_LANGUAGE_STANDARD attribute.
Here's my current knowledge of this code base to see what currently happens and what needs to be done. - The source file Source/cmGlobalXCodeGenerator.cxx is what generates the Xcode file. - Lines 2272 to 2277 (assuming master branch) are where the OTHER_CPLUSPLUSFLAGS are written. - The flags are coming from either one of cflags[*li] or defFlags. defFlags is filled in via GetDefineFlags() within Source/cmMakefile.h, whereas cflags is filled in with the contents of gflags. - Doing a grep for `gnu++11` gives me either .rst files or .cmake files, but no .h or .cxx files. I guess I'm still a little confused as to where I need to modify the Xcode generator. My questions are thus the following: - Is there a proper source location where the standard is defined? - Which variable does it get set to: cflags or defFlags? - Is there a clean way to remove the std flag and place it in a more Apple friendly location, or would I have to do so? Sincerely, Jason Felds
