I met an err when I installed JikesRVM, that is,
我在安装 JikesRVM 的时候遇到了一个错误，就是
skipping incompatible /usr/lib64/gcc/x86_64-suse-linux/4.4/libstdc++.so when searching for -lstdc++
So I am trying to install/update it to a later version. Now, the machine already has
所以我正在尝试将其安装/更新到更高版本。现在机器已经

I am new to openSUSE, could you help?

You need to install 32 bit support for the GNU C/C++ compiler since JikesRVM on x86_64 currently supports only the 32 bit architecture.
您需要为 GNU C/C++ 编译器安装 32 位支持，因为 x86_64 上的 JikesRVM 当前仅支持 32 位架构。
To install this support in OpenSuSE 11.2 type
在 OpenSuSE 11.2 类型中安装此支持
sudo zypper install gcc44-32bit gcc-32bit libstdc++44-devel-32bit
The first two provide runtime support for the C language and the 32-bit version of libgcc, the GCC low level runtime library. The third provides the 32-bit version of libstdc++, both the static import library and the dynamic library. It is the static libstdc++.a that was missing for JikesRVM.
前两个为 C 语言和 32 位版本的 libgcc（GCC 低级运行时库）提供运行时支持。第三个提供32位版本的libstdc++，静态导入库和动态库。JikesRVM 缺少静态 libstdc++.a。
To verify that the 32bit C++ build system is installed correctly you can test it with the following
要验证 32 位 C++ 构建系统是否已正确安装，您可以使用以下命令对其进行测试
echo "int main(){}" | g++ -x c++ -m32 -
NoteOfficial support for OpenSuSE 11.2 has ended. Evergreen support will be available through 2013. Yet it is reasonable to update to 11.3 or a later version soon.
注意OpenSuSE 11.2 的官方支持已结束。Evergreen 支持将持续到 2013 年。但很快更新到 11.3 或更高版本是合理的。
