如何编译 gcc3.2.3？

snlee

第一次用 gentoo，请多多指教。

手头上有些库没有源代码，依赖 libstdc++-v3，所以想编一个 gcc3.2.3 或 gcc3.3.6 来编译链接到这些库的程序。从官网 http://gcc.gnu.org 下载源代码，如果正常的话

../configure --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --enable-languages=c,c++ --disable-libgcj --host=i686-pc-linux-gnu --disable-nls --prefix=/usr/local/gcc-3.2.3

make install

ln -s /usr/local/gcc-3.2.3/bin/gcc /usr/local/bin/gcc32
ln -s /usr/local/gcc-3.2.3/bin/g++ /usr/local/bin/g++32

以后只需要指定  CC=gcc32 CXX=g++32 就可以了，而且对现有的系统没影响，使用也简单。

可惜以上操作用 gcc4.3.3 都编译不通过，难道要先编个 gcc3.4.x 然后用 gcc3.4.x 去编一个 gcc3.2.3 ？

你总得给点出错信息吧

zhllg

ebuild就告诉你应该怎么编译了

再不济，还有sys-libs/libstdc++-v3-bin

你根本不需要自己编译

snlee

嗯，从官网下代码编是不可行的，gcc4对语法检查严格。同时我要得是编译环境而不单单是libstdc++.so.5 的运行环境。

我参考这个
http://wiki.laptop.org/go/Instal ... ntoo_x86_with_GCC_3
最后编出了 gcc3.3.6

总结一下，过程很简单：
emerge -av sys-devel/gcc:3.4
gcc-config i686-pc-linux-gnu-3.4.6
source /etc/profile
emerge -av sys-devel/gcc:3.3
gcc-config i686-pc-linux-gnu-4.3.3
source /etc/profile

这就搞定了
