我是riak的新手并且使用scons构建库。我从https://github.com/ajtack/riak-cpp.git下载了cpp库。我在ubuntu 64上。这是我的gcc版本：
gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4)
在命令提示符下输入：
> scons .
所以......我做了scons的错误吗？或者是代码问题。
以下是我得到的错误;

scons: *** [build/riak/client.o] Error 1
scons: building terminated because of errors.
答案 0 :(得分：1)
尝试升级到gcc 4.6.1，对我来说它运行良好：
