龍芯派從源碼構建linux from scratch

cyberhero

學習孫海勇的《手把手教你構建自己的linux系統》。方案是直接在根目錄建臨時系統後，然後把主系統刪掉，最後編譯目標系統。
4.1.1
su
export SYSDIR=/
mkdir -pv ${SYSDIR}/sources
mkdir -pv ${SYSDIR}/build
chmod -v a+wt ${SYSDIR}/{sources,build}
mkdir -pv ${SYSDIR}/tools
ln -sv ${SYSDIR}/tools /

4.1.2
groupadd mylinux
useradd -s /bin/bash -g mylinux -m -k /dev/null mylinux
passwd mylinux
8位密碼
chown -v mylinux ${SYSDIR}/tools
chown -v mylinux ${SYSDIR}/sources
chown -v mylinux ${SYSDIR}/build
su - mylinux

4.1.3
cat > ~/.bash_profile << "EOF"
exec env -i HOME=${HOME} TERM=${TERM} PS1='\u:\w\$ ' /bin/bash
EOF
cat > ~/.bashrc << "EOF"
set +h
umask 022
SYSDIR=/
LC_ALL=POSIX
PATH=/tools/bin:/bin:/usr/bin
DOWNLOADDIR=${SYSDIR}/sources
BUILDDIR=${SYSDIR}/build
export SYSDIR LC_ALL PATH DOWNLOADDIR BUILDDIR
EOF
source ~/.bash_profile
檢查
export
cat > ${BUILDDIR}/test.c << "EOF"
#include <stdio.h>
main()
{
  printf("OK\n");
  return 0;
}
EOF
測試
gcc ${BUILDDIR}/test.c
./a.out
rm a.out

4.3.1
exit
su
yum install git texinfo -y
su - mylinux
mylinux:~$ cd ${DOWNLOADDIR}
git clone --depth=1 git://cgit.loongnix.org/compiler/toolchain-fc21/binutils-2.24.git
tar -cf binutils-2.24.tar.bz2 binutils-2.24
tar xvf ${DOWNLOADDIR}/binutils-2.24.tar.bz2 -C ${BUILDDIR}
pushd ${BUILDDIR}/binutils-2.24
mkdir -pv ../binutils-build
cd ../binutils-build
CC="gcc -B/usr/bin/" ../binutils-2.24/configure --prefix=/tools --disable-nls --disable-werror
make -j2
make install
make -C ld clean
make -C ld LIB_PATH=/tools/lib
cp -v ld/ld-new /tools/bin
cd ..
rm -rf binutils-build
rm -rf binutils-2.24
popd
檢查
type ld
ls /tools/bin
gcc -v ${BUILDDIR}/test.c 2>&1 | grep Binutils
無顯示，但是去掉grep，可以看到GNU assembler version 2.24 (mips64el-unknown-linux-gnu) using BFD version version 2.24
./a.out

4.3.2
GMP version 6.0.0, MPFR version 3.1.2, MPC version 1.0.2
cd ${DOWNLOADDIR}
git clone --depth=1 git://cgit.loongnix.org/compiler/toolchain-fc21/gcc-4.9.3.git
tar -cf gcc-4.9.3.tar.bz2 gcc-4.9.3/
wget http://ftp.gnu.org/gnu/gmp/gmp-6.0.0a.tar.bz2
wget http://ftp.gnu.org/gnu/mpfr/mpfr-3.1.2.tar.bz2
wget http://ftp.gnu.org/gnu/mpc/mpc-1.0.2.tar.gz
tar xvf ${DOWNLOADDIR}/gcc-4.9.3.tar.bz2 -C ${BUILDDIR}
pushd ${BUILDDIR}/gcc-4.9.3
tar xvf ${DOWNLOADDIR}/gmp-6.0.0a.tar.bz2

mkdir -pv ../gcc-build
cd ../gcc-build
CC="gcc -B/usr/bin/" ../gcc-4.9.3/configure --prefix=/tools --disable-nls --disable-multilib --enable-shared --enable-languages=c
make bootstrap -j2
make install
ln -vs gcc /tools/bin/cc
cd ..
rm -rf gcc-build
rm -rf gcc-4.9.3
檢查
type gcc
ls -l /tools/bin/cc | awk -F/tools/bin/ `{prin $2}'
無返回，但是ls -l /tools/bin/cc 返回/tools/bin/cc -> gcc
ls /tools/bin/$(uname -m)*
gcc -v ${BUILDDIR}/test.c 2>&1 | grep Configured

好！
