下载源码并解压
wget https://github.com/gcc-mirror/gcc/archive/refs/tags/releases/gcc-10.3.0.tar.gz
tar -xvf gcc-10.3.0.tar.gz
切换到解压后的源代码目录
cd gcc-releases-gcc-10.3.0
下载编译依赖并解压
./contrib/download_prerequisites
使用configure脚本进行初始化，生成Makefile
./configure \
CFLAGS='-fstack-protector-strong -Wl,-z,noexecstack -Wl,-z,relro,-z,now' \
LDFLAGS='-fno-PIE' \
--prefix=/root/rpmbuild/BUILD/tools/gcc \
--disable-multilib \
--enable-checking=no \
--enable-languages=c,c++ \
--enable-bolt \
--without-zstd
编译安装
make -j8
make install
遇到编译报错
/usr/bin/ld: gengtype-parse.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
需要在configure里面加上LDFLAGS='-fno-PIE'的编译选项
