Not sure this is the right place, so please redirect me if there exists
someplace more appropriate.
I'm building a cross-toolchain for hurd following [1], and here's a few bugs
I've found along the way:
* Using the tarball from [2], I had to remove an option from GCC's
configure line. The error is also discussed in [3], and followed the advice on
its first response:
diff --git a/cross-gnu b/cross-gnu
index 5dc161e..8d6edd5 100755

# test for its presence.
"$GCC_SRC"/configure \
- --enable-build-with-cxx \
--target="$TARGET" \
--prefix="$ROOT" \
--with-sysroot="$SYS_ROOT" \
* During docs compilation, GCC throws the following error:
/home/lluis/os-tests/hurd/cross-build/src/gcc/gcc/doc/cppopts.texi:763: @itemx
must follow @item
make[1]: *** [doc/cpp.info] Error 1
make[1]: Leaving directory `/home/lluis/os-tests/hurd/cross-build/obj/gcc/gcc'
make: *** [all-gcc] Error 2
I also get similar errors on other files. Replacing "itemx" by "item" in the
first occurrence of a sequence of those fixes it.
* The guide is missing this line for hurd:
( cd src/hurd && autoreconf -vi )
* Error compiling glibc

Adding "@end deftypefun" at the top of file "manual/contrib.texi" fixes it,
although that's just a crude workaround (not sure which file actually forgot
the @end).

Similar errors appear for other files, but I'm not sure what's the proper way
to handle this, since the files are found by make through VPATH, but libtool
receives the naked file name.
I tried adding symlinks for some of them and works, but that's just way too
ugly.
Thanks,
Lluis
