It so happens, that libtool gets distressed when the cross build
loader is in PATH. Having the cross ld in PATH yields a ./libtool
script that has:
# Commands used to build and install a shared archive.
archive_cmds="\$CC -o \$lib \$libobjs \$compiler_flags \\\`echo \\\"\$deplibs\\\"
| sed -e 's/ -lc\$//'\\\` -link -dll~linknames="
which will obviously fail. ld says:
cannot find -link
So, after installing the cross binutils to be packaged, I got rid of it:
mv -f $installroot/$CROSS_PREFIX/$TARGET_PLATFORM/bin/ld ld-in-path-breaks-libtool
Then, you'll get a valid ./libtool script.
However, to determine linkage for Cygwin, libtool needs LD to be set
to the cross loader; and it also needs a C++ compiler that is capable
of linking.
So, here is what did it for me:
CPPFLAGS="-I$PREFIX/include -L$PREFIX/lib -L$PREFIX/lib/w32api -L$PREFIX/bin" \
LD=$TARGET_PLATFORM-ld \
CC="gcc $CPPFLAGS $LDFLAGS" \
CXX="g++ $CPPFLAGS $LDFLAGS" \
./configure --host=$TARGET_PLATFORM
Guile packages coming up now, I'll look at tetex-beta after that (but
no promises).
Greetings,
Jan.
