--- Comment #1 from Alastair Hughes <hobbitalastair at yandex dot com> ---
I believe I have encountered the same issue while attempting to build a MIPS
cross compiler, statically linking against musl libc (2.28.51.20170331 and
2.28). I will attach the objects used during the link.
Here is the collect2 invocation:
$ /pkg/src/gcc-build/gcc/collect2 -plugin
/pkg/src/gcc-build/gcc/liblto_plugin.so
-plugin-opt=/pkg/src/gcc-build/gcc/lto-wrapper
-plugin-opt=-fresolution=/tmp/ccRJho5Z.res -plugin-opt=-pass-through=-lgcc
-plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc
--sysroot=/sysroot --eh-frame-hdr -EB -dynamic-linker /lib/ld-musl-mips.so.1
-melf32btsmip /sysroot/usr/lib/crt1.o /sysroot/usr/lib/crti.o
/pkg/src/gcc-build/gcc/crtbegin.o -L/pkg/src/gcc-build/gcc
-L/opt/mips-linux-musl/mips-linux-musl/bin
-L/opt/mips-linux-musl/mips-linux-musl/lib -L/sysroot/usr/lib /tmp/cc64Bubr.o
-lgcc -lc -lgcc /pkg/src/gcc-build/gcc/crtend.o /sysroot/usr/lib/crtn.o
Linking succeeds without the crt1.o object, albeit complaining about being
unable to find __start - I'm not sure whether this is significant or not, but
presumably you will be able to tell :)
I played around with the file that the configure script was attempting to
build:
$ cat config.c
int
main ()
{
;
return 0;
}
$ /pkg/src/gcc-build/gcc/xgcc -B/pkg/src/gcc-build/gcc
-B/opt/mips-linux-musl/mips-linux-musl/bin/
-B/opt/mips-linux-musl/mips-linux-musl/lib/ -isystem
/opt/mips-linux-musl/mips-linux-musl/include -isystem
/opt/mips-linux-musl/mips-linux-musl-sys-include -g -O2 -minterlink-mips16
config.c -v
$ /opt/mips-linux-musl/mips-linux-musl/bin/ld -melf32btsmip
