If you really followed the README, you should have made a second tree
for the libc build. I don't know if that's really important, though.

In fact, the compiler does not look for the headers of L4 you just
built in the version without libc. There is a reason for that (we
build a cross-compiler for the libc, so he only looks in the standard
include path (quoting Matthieu Lemerre)).
You should simply make a symlink (or a copy if you make everything on
the same tree) of every file you have in hurd-l4/include/ to
/usr/local.

Anyway, I just tried to build it without the symlinks. It failed on
the same line than you, but asking for l4/arch.h and not
l4/ia32/arch.h. It built fine with the symlinks.


Btw, have you used http://hurd.gnufans.org/bin/view/Hurd/QemuImageForL4 ?
