MDK10.1下重用gcc-3.3.2

或许这种做法的确不可取，而且有点是“斩脚趾避沙虫”的做法。但改用回gcc-3.3.2（MDK 10.0 Official）以后，编译很多东西都跟原来一样正常了。想知道大家对这种做法有什么看法？:o

可以Downgrade。

fundawang兄也是夜猫子！呵呵~~

具体怎么做的？能解释一下吗？

可以，我已经把每一个步骤都记在本子上了，明天整理之后就贴上来。现在夜深了，打字太多声音太大，爸惊醒后会骂我“怎么还没有睡觉！！！”

libgcc也换成3.3了吗？

GCC-3.3.3


Introduction to GCC-3.3.3


The reason for installing GCC-3.3.3 is that some BLFS packages (such as compiled Java) have not been updated to be compilable by GCC-3.4.1.

Installation of GCC


Apply the patches:

patch -Np1 -i ../gcc-3.3.3-no_fixincludes-1.patch

The GCC development team recommends building in a separate directory.

mkdir ../gcc-build &&
cd ../gcc-build

Configure GCC to build the C and C++ compilers and enable the related C++ options.

../gcc-3.3.3/configure \
--prefix=/opt/gcc-3.3.3 \
--enable-shared --enable-languages=c,c++ \
--enable-threads=posix

Compile and install GCC:

make bootstrap &&
make install

Move the C++ libraries to the standard lib directory to avoid having to add /opt/gcc-3.3.3/lib to /etc/ld.so.conf.

mv /opt/gcc-3.3.3/lib/libstdc++.so.5* /usr/lib

Configuring GCC


Configuration Information


As with most libraries, there is no configuration to do, save that the library directory i.e., /opt/lib or /usr/local/lib should appear in /etc/ld.so.conf so that ldd can find the shared libraries. After checking that this is the case, /sbin/ldconfig should be run while logged in as root.


If you only need the GCC-3.3.3 libraries, you may delete /opt/gcc-3.3.3.


Whenever you need to use GCC-3.3.3 instead of your system installed compiler, add /opt/gcc-3.3.3/bin to the front of your PATH or (preferably) set the CC environment variable before compiling the concerned package.


Contents


The GCC-3.3.3 package contains the gcc-3.3.3 C and C++ compilers and GCC-3.3.3 libstdc++.so that is required by some commercial and pre-compiled packages.

6692975兄提出了一套完整的升级gcc-3.3.3的方法，我这里还有一套更懒的，不过若按上贴提示，gcc-3.3.2就应该没有添加到那个patch文件吧。（不过MDK怪怪的，经常喜欢把一些正在开发的新特性都添进来。不信？看看那个gtk+2.4.13的源码包就知道了。）

重新安装gcc3.3.2的方法：
1） 卸载gcc-c++,libstdc++5-devel,libstdc++5,gcc,gcc-cpp 这几个包。卸载的具体依赖性请按提示解决，我卸载的顺序就按如上次序。如果其他出现非gcc类编译工具程序的依赖（我就看到有一个叫做rpmbuild的包依赖于gcc-c++），忽略掉吧，并强行卸载gcc-c++。你重新安装之后的包会解决它原来的依赖性的。（并不是要你把rpmbuild这些包也一并卸载喔！！！）

2） 找出你的 MDK 10.0 Official 光盘，依次按上面顺序的逆次序安装。若有提示你缺少某些包（非以上列出的5个），请务必把他们安装上（此时需要的是 MDK 10.1 Official 版本的！）。

3） 顺利安装完以后，使用gcc -v命令，应看到的 gcc 版本为 3.3.2 。

要普通用户了解这些东西是很可笑的

世上没有白吃的饭，也没有坐着等死的人。

这个不错，试一下吧。
