gccgo1.18编译笔记

news 来源：原创 2025/6/8 1:56:18

一、下载依赖：

wget https://gcc.gnu.org/pub/gcc/infrastructure/mpfr-4.1.0.tar.bz2
wget https://gcc.gnu.org/pub/gcc/infrastructure/gmp-6.2.1.tar.bz2
wget https://gcc.gnu.org/pub/gcc/infrastructure/mpc-1.2.1.tar.gz

二、安装依赖：

#依次解压，然后
./configure
make
make install

默认安装到 /usr/local 目录下，包括bin和lib。

三、安装gold（a new, faster, ELF only linker）：

yum install texinfo
# 安装 gold
wget https://mirrors.aliyun.com/gnu/binutils/binutils-2.40.tar.gz
tar -xzvf binutils-2.40.tar.gz
cd binutils-2.40
./configure --prefix=/usr/local/binutils2.40 --enable-gold
make
make install

四、下载gcc代码库（国内镜像），切换到gccgo分支：

git clone https://mirrors.tuna.tsinghua.edu.cn/git/gcc.git  gcc14.0.0-20230626-go1.18
cd gcc14.0.0-20230626-go1.18
git checkout gccgo

五、另外目录编译：

mkdir /opt/gccgo-build
cd /opt/gccgo-build
/opt/gcc14.0.0-20230626-go1.18/configure --prefix=/opt/gcc14.0.0-20230626-go1.18-el8-x64-output --enable-bootstrap --enable-checking=release --enable-languages=go --disable-multilib --with-ld=/usr/local/binutils2.40/bin/ld.gold --with-mpfr-lib=/usr/local/lib --with-gmp-lib=/usr/local/lib --with-mpc-lib=/usr/local/lib
make
make install

如果中途编译出错，重新编译：

cd /opt/gccgo-build
find ./ | grep 'config.cache' | xargs rm

六、设置当前进程的环境变量：

export PATH=/opt/gcc14.0.0-20230626-go1.18-el8-x64-output/bin:$PATH
export LD_LIBRARY_PATH=/opt/gcc14.0.0-20230626-go1.18-el8-x64-output/lib64:$LD_LIBRARY_PATH
