早些时候,我在我的机器上遇到了 Ubuntu的问题。我已经解决了这个问题。目前我正在尝试配置 MPICH 的最新稳定版本(MPICH 3.0.4)。但是,在尝试确定基本数据类型的大小时,它似乎失败了。

按照建议浏览config.log
文件后,我发现配置脚本找不到sys/types.h
或stdlib.h
.

checking for stdint.h... yes
checking for unistd.h... yes

然而,我已经找到了它们:/usr/include/stdlib.h
和
/usr/include/sys/types.h
. 什么可能导致配置脚本找不到这两个系统库?
