Compilation error - GCC 7.4.0

[m-chichikalov]

Hi Дмитрий,

Thank you for such tool and your efforts, really nice... However I'm not able to compile any of the examples.

The invoking make all or g++ -I. test1.cpp leads to

Not sure what to do. Could you mind to help, thank you in advance...

I can reproduce with gcc version 7.4.0 (Debian 7.4.0-1). Running with -M gives me the following output. Something pulls in now, whereas it did not before. Is it ? Not sure what we can do about this. Long term we need to switch to ThreadSanitizer compiler instrumentation. Or extend ThreadSanitizer itself to do what Relacy can do. I won't have time for either of these options.

Thanks for reply. Will think about it.

[JonChesterfield]

This error does not arise with libc++, so stdlib=libc++ may be a workaround.

Hello
Has the problem been solved now？
Can you share the solution?

Has the problem been solved now？

I don't see any PRs referencing this issue. If this still happens on HEAD, it's not solved.

[Kamayuq]

This happens on all compilers now, because some/most header pulls in the atomic header
The solution is simple just abandon your hack of overriding std:: and just have the users change their code to use rl:: or using namespace rl; or some thing like that. It's too slow to use relacy on a large scale anyways, but it is very useful to vet a small data structure.

#18 should have addressed this issue. I'm able to build the main branch with the test/main.cpp test suite using GCC-11/Clang-18 on a Linux based x86_64 system. #19 should address Apple Clang. Both PRs contain fixes to allow "faking" a minimum of the standard library headers (<atomic> in particular).

[...] That is what I do now. Seems to work like a charm.
