Can't help with the prebuilt versions -- they are mostly provided to test
new versions and not used for anything else.
But I will try to help you build it, so please run the following commands
(and never run sudo or login as root unless you absolutely have to).
Please provide both the command and the output -- just cut-n-paste both
from your terminal:
$ uname -a
$ cmake --version
$ gcc -v
$ python -V
This should tell you the defaults that cmake will use. Also, as Serge
noted above, the cmake_error.txt file you provided showed that you were
using the wrong versions of both gcc and python.
If you have newer versions for gcc and python installed on your box, you
can always use the CC and CXX environment variables to select a different
compiler or different version, e.g.,
$ CC=gcc-6.2 CXX=g++-6.2 cmake ../llvm ........
Not sure the best way to set your python version, other than symlink or
alias, but a google search should provide plenty of alternatives.
Once you have fixed those 2 problems, we can try running cmake.
