我试图构建gcc-5.3和binutils-2.26。我这样做了:GCC&binutils构建 - C编译器无法创建可执行文件
mkdir gcc; cd gcc
wget http://path/to/gcc-5.3.0.tar.bz2
wget http://path/to/binutils-2.26.tar.bz2
tar xf gcc-5.3.0.tar.bz2
tar xf binutils-2.26.tar.bz2
cd gcc-5.3.0
contrib/download_prerequisites
for file in ../binutils-2.26/*; do ln -s "${file}"; done
cd ..
mkdir build
mkdir dist
cd build
../gcc-5.3.0/configure --prefix=/home/teamcity/gcc/dist --disable-multilib --with-system-zlib --enable-languages=c,c++,fortran --program-suffix=-mine
make
这似乎是构建第一阶段的可执行文件好吗; prev-gas
,prev-gcc
,prev-ld
都与他们看起来似乎合理的可执行文件。但下一阶段失败:
Configuring stage 2 in ./intl

See `config.log' for more details.
的config.log的相关位似乎是这样的:

/home/teamcity/gcc/build/./prev-gcc/as: 106: exec: /home/teamcity/gcc/build/./gas/as-new: not found
这看起来像上一个-gcc的如希望找到gas/as-new
,而实际上它是prev-gas/as-new
。
有没有一些解决方法呢?是否安全到ln -s prev-gas gas
?我有点期待以后会引起问题。难道不可能一起构建这两个版本的gcc和binutils吗?
错字: wget http://path/to/binutils-5.3.0.tar.bz2应该在路径中可能有2.26而不是5.3.0? –
完全正确。我会解决它。 – Tom
还应该提到构建平台是Ubuntu 14.04,使用与系统安装的GCC 4.8。 – Tom
