binutils question
« on: 26 / December / 2011, 06:39:42 »
I use Gentoo, and need to know if
Code: [Select]
cd binutils-2.18/
./configure --srcdir=`pwd` --target=arm-elf --prefix=${HOME}/arm-elf --disable-werror
make -j 3
make install
will stuff up my normal emerge updates.

I currently have
gcc 4.4.5, with 4.4.3 and 4.5.3 available
binutils 2.21.1-r1
gmp 5.0.2
mpfr 3.0.1_p4

It should install in a subdirectory of your home directory, completely unrelated to your existing gcc configuration.  Since you are installing in your home directory, run the install as your regular user account, not root. That will prevent it from modifying the system stuff even if you mess up the command.

You'll need to set your path appropriately to use it, of course.
Don't forget what the H stands for.

According to the Gcc433 wiki page,

Code: [Select]
mkdir ~/arm-elf
export PATH=~/arm-elf/bin:$PATH
mkdir ~/wa
cd ~/wa

mkdir down
cd down
wget [url][/url]

cd ..
for zipped in down/* ; do tar xjf $zipped ; done # Note: This may take a while.
ln -s $(pwd)/gmp-4.2.4 gcc-4.3.3/gmp
ln -s $(pwd)/mpfr-2.4.2 gcc-4.3.3/mpfr

cd binutils-2.18/
./configure --srcdir=`pwd` --target=arm-elf --prefix=${HOME}/arm-elf --disable-werror
make -j 3
make install
cd ..

ed gcc-4.3.3/gcc/config/arm/t-arm-elf << EOF
/mno-thumb-interwork/s/^# //
/normal interwork/s/^# //

mkdir gcc-4.3.3-arm-elf && cd gcc-4.3.3-arm-elf
../gcc-4.3.3/configure --srcdir=../gcc-4.3.3 --target=arm-elf \
 --enable-multilib --enable-languages=c --enable-clocale=gnu \
 --disable-libm --disable-libc --disable-threads \

 --with-cpu=arm9 --with-newlib --prefix=${HOME}/arm-elf
(unset LIBRARY_PATH; unset CFLAGS; make -j 3 && make install) # Change "3" to "your systems number of cores" + 1
should set up a development environment.  However I'm getting
Code: [Select]
