Severity: normal
User: [email protected]
Usertags: powerpcspe
Hello!
dietlibc currently fails to build from source on powerpcspe because the code
is missing FPU emulation:
test/select.c:12:5: warning: implicit declaration of function 'perror'
[-Wimplicit-function-declaration]
perror("select");

debian/rules:54: recipe for target 'build-stamp' failed
"__unorddf2" is a function in the FPU emulation library present in glibc. In
the past, the FPU emulation code was present in libgcc which is why dietlibc
used to build find on powerpcspe. However, the FPU emulation code in gcc
has been deprecated in favour of the code present in glibc 2.19 or newer [1]
and any recent version of gcc built on a system with glibc 2.19 or newer
will automatically deactivate its built-in FPU emulation code.
I don't know if any FPU emulation code is actually present in dietlibc, but
if there is, it should be enabled similar to what was done in glibc [2].
Cheers,
Adrian
