Re: GCC Installation breaks older header files

This mailing list is for automated mail from our bugzilla database,
not for reporting bugs. It looks like you should be using the gcc-help
mailing list anyway, not reporting a bug. I've CC'd that list. Please
remove the gcc-bugs mailing list from the CC list when replying.

The system information is not very relevant, but you haven't even said
what version of GCC you're using.

I have continuously attempted to compile newer versions of GCC from source but my system continuously fails to compile the code. I am not sure if there is any recovery path to restore success for applications that had depended on these headers. Sorry for the interruption.

Nobody can help you with such a vague description of the problem.

What do you mean "broken"? Which header files? What happens?

What command are you running, and what errors do you get?

Where did you install the new GCC? Did you overwrite an old version,
or install to a different location? How did you configure and build
GCC?

Maybe you just need to run the mkheaders script as documented at
https://gcc.gnu.org/onlinedocs/gcc-14.1.0/gcc/Fixed-Headers.html
