Issue while compiling: "/usr/bin/cc - broken"

[SimoneTomasella]

I followed the INSTALL.md instructions for Linux (export CC=clang and export CXX=clang++, and the cmake instructions).
But it keeps giving me this error and I wasn't able to fix it :c
I need some help

-- The C compiler identification is GNU 13.2.1

CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:67 (message):
The C compiler

"/usr/bin/cc"

is not able to compile a simple test program.

It fails with the following output:

I'm using Manjaro Linux

Are you sure you did the export correctly? Your output says

-- The C compiler identification is GNU 13.2.1
-- The CXX compiler identification is GNU 13.2.1

Which is wrong. libc++ is standard library for clang.

Maybe it's possible you don't have clang installed? Make sure you have clang installed with sudo pacman -Sy clang and try again.
