Subject: Unable to build with --enable-shared

Message-ID: <CAJ4e7SU19GkpcqWgwQeDkHmWg4mwHp5YU6VD3xZLEJq2KqXQLQ@mail.gmail.com> (raw)
Hi!
I am unable to build musl with --enable-shared. Multiple issues in
unrelated projects (e.g. here: https://bugs.swift.org/browse/SR-1023)
suggest that the culprit is a change in behaviour between binutils
2.25 and 2.26.
This is what I did:
$ make clean
$ ./configure --prefix=/usr/packages/musl --target=x86_64-pc-linux-gnu
CFLAGS='-B/usr/local/bin/x86_64-pc-linux-gnu-' --enable-static
--enable-shared --disable-gcc-wrapper
$ make

-I./include -include vis.h -B/usr/local/bin/x86_64-pc-linux-gnu-

/usr/local/bin/x86_64-pc-linux-gnu-ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
make: *** [lib/libc.so] Error 1
This is the toolchain I am using:
$ /usr/local/bin/x86_64-pc-linux-gnu-ld -v
GNU ld (GNU Binutils) 2.27
$ x86_64-pc-linux-gnu-gcc -v
Using built-in specs.

Thread model: posix
gcc version 6.1.0 (GCC)
Can anyone confirm this issue with binutils >= 2.26? It seems strange
to me that this would not have come up yet, so maybe someone has an
idea what else might be the problem?
