FizzCommandCommon.cpp: error: no matching function for call to 'std::basic_string<char>::erase(__gnu_cxx::__normal_iterator<char*, std::basic_string<char> >, std::basic_string<char>::const_iterator)'

[barracuda156]

Could someone say why this may fail?
(To be clear, this is not necessarily a bug in fizz code, since we have to patch folly in a few places to fix it for Big-endian platforms, but it could be a fizz bug.)

[barracuda156]

To be honest it looks like there is something wrong with types in fizz; it is unlikely to have anything to do with what we patch in folly.

[barracuda156]

Also fails with C++20 same way:

These two commits have broken it: 6efc106 and 235358c

[NickR23]

Hey @barracuda156,
I'm having trouble reproducing this build error on my MacOS 14.2.1 environment. Could you give more details on how you're building this?

Thanks

[barracuda156]

@NickR23 This is likely specific to libstdc++. While I have 14.2.1, I do not have a functional setup with libstdc++ on it at the moment.

My log is from 10.6 on PowerPC with gcc 13.2.0, but I suspect it should be reproducible on Intel as long as gcc with libstdc++ is used.

[barracuda156]

@NickR23 Still fails with v2024.01.22.00. Could I assist somehow with debugging beyond the log? If you suggest what I could try, I will do it.
It would be really nice to fix this properly instead of having to revert two commits.
