[cmake-developers] [CMake][BUG] C++11 support broken for SolarisStudio 12.4

[CHEVRIER, Marc]

Hi,

Currently, it is not possible to use C++11 mode on Solaris with SolarisStudio 12.4 (test done on Solaris 11.2 sparc).
If I try a simple executable (see attached file), compilation is OK (option –std=c++11 is correctly passed to compiler) but link failed because, with SolarisStudio compiler, option –std=c++11 is also required at link time and is currently missed.
And unfortunately, it seems there is no equivalent to compile configuration variable CMAKE_CXX11_STANDARD_COMPILE_OPTION for the linker so no so easy to fix this problem…

Here is the log (see red lines):
/opt/solarisstudio12.4/bin/CC    -std=c++11 -o CMakeFiles/Test.dir/test.cpp.o -c /usr/u/i051466/tests/cmake/build/test.cpp

FYI:
* If I add option –std=c++11 in the file …/Test.dir/link.txt, link is successful
* I built CMake using version 12.2 of SolarisStudio because if I use SolarisStudio 12.4, cmake tool is unsuable (I will sent another mail describing this problem).
