Gentle ping.
Gentle reminder that I strongly suspect that your buildroot is corrupt.
There *should* be a <fenv.h> present.

The fp-bench test (i. e. tests/fp/fp-bench.c) use fenv.h that is not

Since uclibc has had fenv.h since 2008, are you sure this isn't simply a case
of a corrupt
installation?

It's not an issue of corrupted installation but rather of compilation:
Installation of your cross-compiler or buildroot, I mean.
../tests/fp/fp-bench.c:15:10: fatal error: fenv.h: No such file or directory
15 | #include <fenv.h>
| ^~~~~~~~
compilation terminated.
Yes, yes. However, <fenv.h> is present in uclibc-ng, and has been since 2008.
So *why* is fenv.h not present?
I found the fenv.h files here:
out/emulator/host/opt/ext-toolchain/i686-buildroot-linux-uclibc/include/c++/11.3.0/tr1/fenv.h
out/emulator/host/opt/ext-toolchain/i686-buildroot-linux-uclibc/include/c++/11.3.0/fenv.h
But the compiler expects them in:
out/emulator/host/i686-buildroot-linux-uclibc/sysroot/usr/include/
So, I think that the fenv support has not been enabled in uClibc
configuration of Buildroot.
Thanks and regards,
Dario
