我正在开发一个 android cmake 项目,该项目可以在我的 32 位 Ubuntu 12.04 机器上成功编译(我将其称为 WorkMachine)。当我想在家里编译时,我安装了一个 32 位的 Ubuntu 12.04 虚拟机(我将它称为 HomeMachine),我在上面 git 克隆了项目,当我开始编译时,它会阻塞并报错。

这里我报告 gcc 版本(两台电脑都一样)
gcc -v
Using built-in specs.

但这怎么可能?似乎问题不是由于某些 cmake 缓存或类似的 chaches,因为如果我将项目 git clone 到 WorkMachine 上的另一个目录中,代码也编译得很好。我可以检查什么来解决问题?如果您需要更多详细信息,请询问我。
感谢您的时间。
