I want to install llvm-clang but have no root access at work. many of our packages are outdated so I am installing everything locally under my home directory.
I installed cmake and gcc but now having errors when installing llvm.
I have my home directory structured this way:
~/gcc_build -> has the /bin directory which includes gcc, g++...etc (result of make install).
~/gcc-7.1.0 -> which has the main gcc build directory (where make was run)
~/llvm-4.0.0.src -> the main llvm directory
~/llvm_make -> where I am trying to make llvm in (empty)
This is my command:
[server-01:llvm_make]% ../cmake-3.8.2/bin/cmake ../llvm-4.0.0.src -DCMAKE_CXX_COMPILER=/home/sbay/gcc_build/bin/g++ -DCMAKE_C_COMPILER=/home/sbay/gcc_build/bin/gcc
But I am getting this error:
[server-01:llvm_make]% ../cmake-3.8.2/bin/cmake ../llvm-4.0.0.src -DCMAKE_CXX_COMPILER=/home/sbay/gcc_build/bin/g++ -DCMAKE_C_COMPILER=/home/sbay/gcc_build/bin/gcc

CMake Error at /home/sbay/cmake-3.8.2/Modules/CMakeTestCCompiler.cmake:51 (message):
The C compiler "/home/sbay/gcc_build/bin/gcc" is not able to

It fails with the following output:

I would highly appreciate any input.
You can try adding --sysroot= option e.g.--sysroot=/home/lz/olimex/gcc-4.3.3/
