Cannot compile with Profile build type

[danbone]

I'm trying to compile with CMAKE_BUILD_TYPE=Profile but I'm getting the following error:

/home/dan/anaconda3/envs/sparta/bin/../lib/gcc/x86_64-conda-linux-gnu/12.3.0/../../../../x86_64-conda-linux-gnu/bin/ld: /home/dan/anaconda3/envs/sparta/bin/../x86_64-conda-linux-gnu/sysroot/usr/lib/../lib/gcrt1.o: relocation R_X86_64_32S against symbol `__libc_csu_fini' can not be used when making a PIE object; recompile with -fPIE
/home/dan/anaconda3/envs/sparta/bin/../lib/gcc/x86_64-conda-linux-gnu/12.3.0/../../../../x86_64-conda-linux-gnu/bin/ld: failed to set dynamic section sizes: bad value

Has anyone else encountered this?

I don't have that issue, but a different one. Specifically stf is built with LTO while the linking stage doesn't accept it. Got a flag mismatch.

Have you tried with clang?

[danbone]

Same error as this?

Managed to fix it by moving the setup_stf_linker out of the Release build only

Yep. That’s the one.

@danbone Can I take up this issue?

[klingaard]

Unless Dan disagrees, feel free to take it. I just reproduced the original issue.

[danbone]

@klingaard didn't this get fixed by https://github.com/riscv-software-src/riscv-perf-model/commit/9d9a345060039594b2782520e743ab5ec2a613d3

@danbone Can I take up this issue? If you allow me to do so.. I think in this issue we are supposed to work on "-fPIE" error during compilation, with "CMAKE_BUILD_TYPE=Profile" in conda environment. It will be solved by adjusting compiler flags for PIE compatiability. I am interested to work on this

[danbone]

Yes, absolutely fine by me
