The problem is that static archives can't declare implicit dependencies: if
you link dynamically, libX11.so will implicitly depend on libxcb.so, but if
you link statically you must also explicitly link against -lxcb.

Hi all,
I'm trying to cross-compile xmobar for aarch64-linux-gnu. The cross compiler that comes with my version of Ubuntu works with a later GLIBC than the host platform, so I figured I'd make a static executable instead - this approach had worked with e.g. cabal-install.
Unfortunately, I get the following:
Resolving dependencies... Build profile: -w ghc-8.6.4 -O1 In order, the following will be built (use -v for more details): - xmobar-vanessa-0.1.0.0 (exe:xmobar) (first run) Preprocessing executable 'xmobar' for xmobar-vanessa-0.1.0.0..

I looked in libX11.a with
nm /usr/aarch64-linux-gnu/lib/libX11.a | rg 'xcb_take_socket'
which yields
U xcb_take_socket
which, as I understand, means that something is screwed up in the X11 static linking (but I know less about systems programming and linkers than Haskell).
Does anyone know how to fix such a problem?
