Subject: problems with dynamic linking since 0.9.1
Hello!
Dynamic linking with musl has stopped working for me since musl 0.9.1.
I havent tested all versions but 0.9.6 and 0.9.12 does not work.
Im still using that strange uclibc environment where gcc is itself a
wrapper that calls rawgcc.
Info for 0.9.1 and 0.9.12 below.
Any ideas or pointers welcome.
Regards,
Jens
0.9.1 (working):
bash-4.1# musl-gcc -v t.o
Using built-in specs.
Reading specs from /opt/musl/lib/musl-gcc.specs
rename spec cpp_options to old_cpp_options
rename spec link to old_link
