Why doesn't PTS system-info see GCC?

[blueweb]

With phoronix test suite v7.8.0 and v8.0.1, system-info shows:

OPERATING SYSTEM:   Fedora 28
    Kernel:           4.17.18-200.fc28.x86_64 (x86_64)
    Desktop:          MATE 1.20.2
    Display Server:   X Server 1.19.6
    Compiler:         Clang 6.0.1 + LLVM 6.0.1 + CUDA 9.1
    Security:         SELinux + __user pointer sanitization + Full AMD retpoline IBPB + SSB disabled via prctl and seccomp Protection

But GCC is installed:

$ gcc --version
gcc (GCC) 8.1.1 20180712 (Red Hat 8.1.1-5)

No issues here on Fedora 28 with the same GCC build... Did you change your PATH with anything odd or anything of that like?

[blueweb]

Not to my knowledge.

$ $PATH
bash: /usr/lib64/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/[USER]/.local/bin:/home/[USER]/bin: No such file or directory

I noticed the lack of GCC when I ran a benchmark from an article and noticed the difference in compiler info between my system and the reference.

I uninstalled Clang to see if that would remove some conflict. Still no GCC:

  OPERATING SYSTEM:   Fedora 28
    Kernel:           4.17.18-200.fc28.x86_64 (x86_64)
    Desktop:          MATE 1.20.2
    Compiler:         LLVM 6.0.1 + CUDA 9.1
    Security:         SELinux + __user pointer sanitization + Full AMD retpoline IBPB Protection

If you drop the ccache dir from the path does it work?

[blueweb]

Removing ccache from the PATH works! Isn't ccache installed by default? What could be messing up my system?

Maybe unrelated, but I also noticed that some benchmarks are way off from the reference results for the same CPU. Eg. on my 2700X smallpt takes ~45 seconds while the reference is ~12s. But if I run PTS in docker it's 13s.

Michael Could you perhaps test installing ccache on Fedora 28 to confirm the compiler reporting behavior with PTS?

I believe ccache was installed when I installed the "C Development Tools and Libraries" group of packages. (dnf group install "C Development Tools and Libraries")
