基于3c2410的linux2.6.22移植（3）

4、 生成第一階段gcc： arm/build-tools/%23">$root@host:/home/arm/build-tools/# tar xvjf gcc-4.2.1.tar.bz2
打補(bǔ)?。?br />$root@host:/home/arm/build-tools/# cd gcc-4.2.1
$root@host:/home/arm/build-tools/gcc-4.2.1#
patch –Np1 –i /home/arm/build-tools/patch/gcc-4.2.1-*
$root@host:/home/arm/build-tools/ gcc-4.2.1# cd ..
$root@host:/home/arm/build-tools/# cd build-boot-gcc
$root@host:/home/arm/build-tools/build-boot-gcc#
../gcc-4.2.1/configure --target=${TARGET} --prefix=${PREFIX} --with-headers=${TARGET_PREFIX}/include
--with-newlib --enable-languages=c --disable-threads --disable-shared
$root@host:/home/arm/build-tools/build-boot-gcc # make all-gcc
$root@host:/home/arm/build-tools/build-boot-gcc # make install-gcc
在${PREFIX}/bin下會(huì)生成 arm-linux-開頭的文件：
$root@host:/home/arm/build-tools/build-boot-gcc # ls ${PREFIX}/bin
5、 生成glibc庫文件：
$root@host:/home/arm/build-tools/build-boot-gcc # cd ..
$root@host:/home/arm/build-tools# cd build-glibc
$root@host:/home/arm/build-tools/build-glibc# CC=arm-linux-gcc ../glibc-2.6.1/configure --host=$TARGET --prefix=”/usr”
--enable-add-ons --with-headers=${TARGET_PREFIX}/include
--cache-file=config.cache
這里的config.cache與前面編譯glibc頭文件時(shí)的config.cache完全相同。
$root@host:/home/arm/build-tools/build-glibc# make
$root@host:/home/arm/build-tools/build-glibc#
make install_root=${TARGET_PREFIX} prefix=”” install
對libc.so作出修改：
$root@host:/home/arm/build-tools/build-glibc# cd ${TARGET_PREFIX}/lib
$root@host:/home/arm/tools/arm-linux/lib# cat libc.so

OUTPUT_FORMAT(elf32-littlearm)
GROUP ( /lib/libc.so.6 /lib/libc_nonshared.a AS_NEEDED ( /lib/ld-linux.so.2 ) )
將GROUP這一行的內(nèi)容改為：
GROUP ( libc.so.6 libc_nonshared.a AS_NEEDED ( ld-linux.so.2 ) )
$root@host:/home/arm/tools/arm-linux/lib# cat libpthread.so

OUTPUT_FORMAT(elf32-littlearm)
GROUP ( /lib/libpthread.so.0 /lib/libpthread_nonshared.a )
將GROUP這一行的內(nèi)容改為：
GROUP (libpthread.so.0 libpthread_nonshared.a )
6、 生成完整的編譯工具：
$root@host:/home/arm/tools/arm-linux/lib# cd ${PRJROOT}/build-tools/build-gcc
$root@host:/home/arm/build-tools/build-gcc#
../gcc-4.2.1/configure --target=$TARGET --prefix=${PREFIX} --enable-shared
--enable-languages=c,c++ --with-threads=posix
$root@host:/home/arm/build-tools/build-glibc# make all
$root@host:/home/arm/build-tools/build-glibc# make in install
