Hi all, I am trying to cross-compile xmobar for ARM and unfortunately my C cross-compiler uses a different libc version; I figured static linking would give me a usable binary. Unfortunately, trying to cross-compile yields:

collect2: error: ld returned 1 exit status `aarch64-linux-gnu-gcc' failed in phase `Linker'. (Exit code: 1) I've had a look at libX11.a with nm /usr/aarch64-linux-gnu/lib/libX11.a | grep 'xcb_take_socket' which returns U xcb_take_socket As far as I can tell, the initial failure is expected given that result. But I still don't know how to build libX11.a "properly" to get rid of the Us. Thanks! Vanessa McHale
