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

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).
