ARM GCC 도구 체인 구축

1. 다운로드 코드는 다음과 같습니다.

binutils-2.24.tar.bz2  glibc-2.17.tar      linux-3.10.28.tar
gcc-4.8.0.tar.bz2      glibc-2.19.tar.bz2

2. binutils 컴파일
binutls 코드를 src 디렉터리에 압축을 풀고build 디렉터리에 binutil 디렉터리를 만듭니다.
build/binutils 디렉토리에서 다음을 수행합니다.

../../src/binutils-2.24/configure --prefix=/home/charles/code/cross-compile-arm/toolchain --with-sysroot=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot --target=arm-linux-gnueabi

그리고make-j10,makeinstall을 실행합니다.
3. 커널 헤드 파일 설치
커널 코드를 src 디렉토리에 압축을 풀고 커널 코드 디렉토리에 들어가서 다음을 수행합니다.

make mrproper
make ARCH=arm vexpress_defconfig
make ARCH=arm headers_check
make ARCH=arm INSTALL_HDR_PATH=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot/usr headers_install
 
find ../../toolchain/arm-linux-gnueabi/sysroot/usr/include/ -name ".install" -or -name "..install.cmd" | xargs rm -fv

4.bootstrap GCC 만들기
디렉터리build/gcc 만들기first, 그리고 이 디렉터리에 들어가서:

 ../../src/gcc-4.8.0/configure --build=i686-pc-linux-gnu  --target=arm-linux-gnueabi --prefix=/home/charles/code/cross-compile-arm/toolchain --with-sysroot=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot --with-newlib --without-headers --disable-threads  --enable-__cxa_atexit --disable-libmudflap --disable-libgomp --disable-libssp --disable-nls  --disable-shared  --with-gnu-ld  --with-gnu-as --enable-languages=c --with-float=softfp --with-fpu=vfpv3 --with-cpu=cortex-a15 --with-tune=cortex-a15  --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --with-mode=arm

이후 다음을 수행합니다.

make all-gcc install-gcc

make all-target-libgcc install-target-libgcc

5. GLIBC 컴파일
먼저 실행:

export PATH=$PATH:/home/charles/code/cross-compile-arm/toolchain/bin

디렉터리build/glibc를 만들고 이 디렉터리에 들어가서 실행하십시오:

 CC=arm-linux-gnueabi-gcc AR=arm-linux-gnueabi-ar  RANLIB=arm-linux-gnueabi-ranlib ../../src/glibc-2.17/configure   --build=i686-pc-linux-gnu  --host=arm-linux-gnueabi --prefix=/usr --with-headers=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot/usr/include  --enable-add-ons --with-mode=arm

다음을 수행합니다.

make; make install install_root=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot

6.최종 gcc 컴파일:
디렉터리build/gcc 만들기final, 실행:

../../src/gcc-4.8.0/configure --build=i686-pc-linux-gnu --target=arm-linux-gnueabi --prefix=/home/charles/code/cross-compile-arm/toolchain --with-sysroot=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot --disable-libmudflap --disable-libssp --disable-nls --disable-libstdcxx-pch --with-interwork --with-mode=arm --with-fpu=vfpv3 --with-cpu=cortex-a15 --with-tune=cortex-a15 --with-float=softfp --enable-libgomp --enable-poison-system-directories --enable-symvers=gnu --enable-long-long --enable-threads --enable-languages=c,c++ --enable-shared --enable-lto --enable-__cxa_atexit --with-gnu-as --with-gnu-ld --enable-__cxa_atexit  --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local

다음을 수행합니다.

make all
make install

마지막으로 생성된 도구 체인은 다음과 같습니다.

$ arm-linux-gnueabi-gcc -v
Using built-in specs.

============================================
1. cortex-a9의 경우 다음과 같이 구성됩니다.
bootstrap gcc:

../../src/gcc-4.8.0/configure --build=i686-pc-linux-gnu  --target=arm-linux-gnueabi --prefix=/home/charles/code/cross-compile-arm/toolchain --with-sysroot=/home/charles/code/cross-compile-arm/toolchain/arm-linux-gnueabi/sysroot --with-newlib --without-headers --disable-threads  --enable-__cxa_atexit --disable-libmudflap --disable-libgomp --disable-libssp --disable-nls  --disable-shared  --with-gnu-ld  --with-gnu-as --enable-languages=c --with-arch=armv7-a --with-float=softfp --with-fpu=vfpv3  --with-tune=cortex-a9  --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --with-mode=arm
