that were causing this have been resolved with some updates so allow the
uclibc+gcc13 combination again.

fenv.h provides functions to control the floating point environment,

For some architectures, fenv.h is incomplete, so is not installed

by default. x86 is known to have a rather complete fenv.h, so it is
|
|
installed by default only for x86.

If you need fenv.h on other architectures, say 'y' here, but you may

encounter some issues.

Depending on where the resulting toolchain will be used, you may need

to tweak the "system" part of the target tuple. Buildroot prefers
|
|
to have arm-*-linux-uclibcgnueabi; OpenEmbedded prefers
|
|
arm-*-linux-uclibceabi. Other tools seem to either accept both, or
|
|
don't care about the suffix.
