[CMake] No CMAKE_CXX_COMPILER could be found

[Parag Chandra]

Hi Jon,

I can't really explain why, but I've seen the same problem on a colleague's Mac as well. On my machine, it works just fine, but to get it working across all of our Macs, I find I need to explicitly define the compilers by passing these arguments to CMake on the command line:

-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++

Hope this works for you too.

HI,

Running OSX Snow Leopard, XCode 5.1.1

Command line tools installed.

If I type
clang --version
at the command line I get version 5.1


CMake 3.2.2

The first lines of outpuit I get are

The CXX compiler identification is AppleClang 5.1.0.5030040
The C compiler identification is AppleClang 5.1.0.5030040

But then it bombs out at the line

PROJECT(${PROJECT_NAME} CXX C)

with the error

No CMAKE_CXX_COMPILER could be found

CMake 2.8.11 doesn't bomb out at that point (but does later due to the fact hat this CMakelist.txt file uses functionality that has changed).

Anybody got any idea what is going on?

cheers

Jon
