Hi,
There appears to be a difference in what C++ compiler is detected on OS X,
depending on what generator is selected.
Xcode generator:
-- The C compiler identification is GNU 4.2.1
-- The CXX compiler identification is GNU 4.2.1
Makefiles generator:
-- The C compiler identification is GNU 4.2.1
-- The CXX compiler identification is Clang 3.1.0
This 'breaks' a number of open source projects (BZip2 and Assimp are two
examples I have encountered), as this piece of code seems to be common:
if (CMAKE_COMPILER_IS_GNUCXX)
set ( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fpic")
set ( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fpic")
endif (CMAKE_COMPILER_IS_GNUCXX)
For now, i've been adding "OR APPLE" to the if condition, although I'm not sure
if that's the right approach.
Is Clang still considered to be "gcc compatible"?
-Matt.
