[CMake] cmake 3.7.2 centos 7 :: kwsys.testSystemTools (Failed)

[Chuck Atkins]

Hi Adrian,

So, would this imply that cmake is not supported on EL7 because gcc does

That's not really what's happening.  CMake is testing the C compiler to
determine whether or not it supports C11 features and the C++ compiler to
see if it supports C++11.  The error messages are expected in many of the
test cases.  Here it's jsut checking to see if what it knows about the
features supported by the specific version of GCC line up correctly with
reality.  i.e. CMake thinks that gcc 4.8.2 supports certain features so it
tests them to make sure.  So it's not saying that CMake isn't supported,
just that the 1 specific test failed for some reason.

All that being said, I wasn't able to reproduce the error with the current
3.7.2 release:

[chuck.atkins at deepthought v3.7.2]$ lsb_release -d
Description:    CentOS Linux release 7.3.1611 (Core)
[chuck.atkins at deepthought v3.7.2]$ gcc --version

...
[chuck.atkins at deepthought v3.7.2]$ ../../source/v3.7.2/bootstrap
--parallel=28

CMake has bootstrapped.  Now run gmake.
[chuck.atkins at deepthought v3.7.2]$ make -j28

[chuck.atkins at deepthought v3.7.2]$

What specific versionof EL7 are you running and which version of GCC?
