webkitgtk+的编译要用到4.8+的GCC 人家ubuntu都有编译好的gcc。。。可怜我centos只能编译源代码了。。。
废话不说,速度干活
下载
先下载需要的GCC源码,http://gcc.gnu.org/
以gcc-4.8.3为例 先解压文件
cd ~
mkdir src
cd src
wget http://自己写吧
tar xf gcc-4.8.3.tar.gz
到这一步停下,还有软件包没有下载安装,难点重点就在这儿了,这三个软件包的安装顺序不能乱,而且安装后一个软件之前必须指定前面安装的路径,很麻烦!
下载源代码可以执行gcc-4.8.3/contrib下的download_prerequisites脚本,即可自动下载,到时候也好一起编译
GMP GMP is the GNU Multiple Precision Arithmetic Library.
cd gmp
./configure --disable-shared --enable-static --prefix=/tmp/gcc
make && make check && make install
MPFR MPFR is the GNU Multiple-precision floating-point rounding library. It depends on GMP.
cd mpfr
./configure --disable-shared --enable-static --prefix=/tmp/gcc --with-gmp=/tmp/gcc
make && make check && make install
MPC MPC is the GNU Multiple-precision C library. It depends on GMP and MPFR.
cd mpc
./configure --disable-shared --enable-static --prefix=/tmp/gcc --with-gmp=/tmp/gcc --with-mpfr=/tmp/gcc
make && make check && make install 下面才是主角GCC,他的编译需要在另一个文件夹中进行
编译
接下来开始编译gcc
cd /home/src
mkdir gcc-build
cd gcc-build
../gcc-4.8.3/configure --enable-checking=release --enable-languages=c,c++ --disable-multilib --with-gmp=/tmp/gcc --with-mpfr=/tmp/gcc --with-mpc=/tmp/gcc
make -j4 && make check && make install
可能出现的错误:
1./usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file 解决办法:
yum install glibc-devel
yum install glibc-devel.i686
#Ubuntu下: apt-get install libc6-dev-i386
2.找不要依赖包 这个嘛。。。自己yum search吧!
ps. 安装之前最好安装一下开发环境
Ubuntu:
apt-get install build-essential
centos:
yum groupinstall "Development Tools"
3.检查gcc版本
gcc -v
2014-6-18更新快键安装代码(请以root权限运行)
cd ~
mkdir src
cd src
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.3/gcc-4.8.3.tar.bz2
tar jxf gcc-4.8.3.tar.bz2
cd gcc-4.8.3
./contrib/download_prerequisites
cd ..
mkdir gcc-build
cd gcc-build
../gcc-4.8.3/configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
make -j4
make check
make install
