I'm trying to build a musl version of xclock. If I can build xclock then I hope to be able to build my app which is more complicated. I'm getting the following error.

/usr/bin/ld: h_errno: TLS definition in //lib/i386-linux-gnu/libc.so.6 section .tbss mismatches non-TLS definition in /home/mudd/musl/musl-1.1.8.install/lib/libc.so section .bss

"Yes, you're linking to glibc, or to something that was linked with

looks like you're using the host system's gcc and passing the

musl-gcc.specs file to it manually rather than using the musl-gcc

script or a real musl-targetted compiler toolchain, so it might be

something to do with that too. Adding -v to the command line and

seeing what gets passed to the linker command could be helpful."

It doesn't look like any of my musl compiled libs point to libc.so.6.

$ readelf -a ./*.install/lib/lib*.so | grep libc.so.6

Here's what the X11 libs point to. I've built and referenced all of these dependencies using musl.

$ readelf -a ./*.install/lib/libX*.so | grep NEED | sort -u
