Possibly similar to rust-lang/rust#76984

libgcc_eh is the exeption handling library by gcc

It may not be the same as this question. I am using gnu gcc, not TDM-GCC and MinGW. You can take a look at the .config file I uploaded. And when I use gcc 7.5.0, this error will be reported, but gcc 13.2.0 will not report an error.

[QBos07]

TDM-GCC and MinGW both use gcc. gcc in itself sands for gnu compiler collection or gnu c compiler.

[iGwkang]

So is there a solution to this?

[cpackham]

The best solution would be to use a newer version of GCC.

The best solution would be to use a newer version of GCC.

However, other dependencies in my project are compiled using gcc7. If compiled with a newer version of gcc, it will not be compatible with the previous library. Recompiling all dependencies is very labor intensive.

[QBos07]

AFAIK the only library (libgcc) that comes with gcc is staticly linked and abi compatible to never versions.
There shoudn't be a problem with using a newer compiler. Have you tried it?

I've experimented with compiling using GCC 13. In my project, I'm using static libraries. When attempting to compile with a higher version of GCC, I encounter LTO (Link Time Optimization) linking errors. Even when disabling LTO optimization, other errors persist. Therefore, it's crucial to maintain consistency in the GCC version throughout the project.

[QBos07]

IMO recompiling everything using gcc 13 is more future proof. I know something like this can take a while but it schoudn't be more than 3-2 days. Build servers can minimize the downtime of not compiling in the night or similar.
