My project requires using gcc 4.0 when compiling on Mac OS X, as it has to
support 10.4. This works fine for the makefile generator, but it breaks with
the XCode generator for Xcode 3.2 as the default gcc is v4.2.
Other posts on this list indicates that it's a bug in the Xcode generator. I
would like to workaround this issue somehow until a new version of cmake is
released.
One poster suggested using gcc's -V option, which allows forcing the gcc
version. I've tried injecting this into the CMAKE_CXX_FLAGS like this:
if (${CMAKE_GENERATOR} MATCHES "Xcode")
set(CMAKE_CXX_FLAGS "-V 4.0 ${CMAKE_CXX_FLAGS}")
endif(${CMAKE_GENERATOR} MATCHES "Xcode")
However, this creates a new error:
'-V' must come at the start of the command line
It seems that the CMAKE_CXX_FLAGS are always appended to the constructed gcc
command. Is there some way that I can prepend flags (that is, put them at the
very beginning of the command-line)?
Thanks,
aaron
