Re: [microblaze-uclinux] toolchain build instructions

Ok, good job. Small mod, though. See below:

...
# first build binutils:
cd ${EDKSRC}/binutils/microblaze
./configure --target=microblaze --prefix=${RELDIR}
make all CFLAGS="-O2 -g -DMICROBLAZE -DEDK" CXXFLAGS="-O2 -g
-DMICROBLAZE -DEDK"make install
 
+# link microblaze-as to mb-as
+ln ${RELDIR}/bin/microblaze-as ${RELDIR}/bin/mb-as
 
# add newly created binutils to the path
export PATH=${PATH}:${RELDIR}/bin
...
 
This is needed because mb-as is hardcoded into the gcc specs as the name
of the assembler. There's probably another way to do it within the
binutils configure script, but this was quick and easy... :)

I've hit a problem during the build process, though. While make install
is running in gcc, I get this:

...
make[2]: Entering directory
`/home/bab/mb-gcc-src/gcc/libiberty/testsuite'
make[2]: Nothing to be done for `install'.
make[2]: Leaving directory
`/home/bab/mb-gcc-src/gcc/libiberty/testsuite'
make[1]: Leaving directory `/home/bab/mb-gcc-src/gcc/libiberty'
make[1]: Entering directory `/home/bab/mb-gcc-src/gcc/microblaze/libio'
#rm -rf _G_config.h
cp ./_G_config.h .
cp: cannot stat `./_G_config.h': No such file or directory
make[1]: *** [install] Error 1
make[1]: Leaving directory `/home/bab/mb-gcc-src/gcc/microblaze/libio'
make: *** [install-target-libio] Error 2

After looking at the makefile and makefile.in, it appears that the
srcdir variable is incorrectly set, but this smells more like another
configure error and as such I don't think just changing the sources is
how I need to fix it. Anyone else seen this?
