[Message part 3 (text/plain, inline)]

Hello,

I have been attempting to crosscompile gzip for a linux system that uses
the musl libc using clang, and I have come across an issue while
attempting to configure gzip.

I set CC="cross-clang", and run ./configure --prefix=/usr --host=x86_64.
cross-clang is just a wrapper script that sets the sysroot for
crosscompiling.  The configuration fails, and I get the following error:

checking how cross-clang reports undeclared, standard C functions...
configure: error: in `/home/user/Desktop/cross-compiling/build/gzip/gzip':
configure: error: cannot detect from compiler exit status or warnings

I have used a similar setup to successfully crosscompile many other pieces
of software, so I am not entirely sure why gzip is not configuring.  Any
suggestions for getting around the issue or suggested software changes
would be greatly appreciated.

Thanks,

Caleb Heydon

No further comment on this old bug report, so I'm taking the liberty of
