Question

我不熟悉Ruby，但使用的是需要构建一些Ruby原生扩展的系统实用程序。当我尝试运行安装命令时，我得到以下stacktrace：

Building native extensions.  This could take a while...
ERROR:  Error installing sensu-plugins-http:
    ERROR: Failed to build gem native extension.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

由于各种原因，我的/tmp/目录故意很小。我想知道，有没有办法让Ruby / gcc使用不同的临时位置进行构建过程？

Answer 1

是。在编译之前设置TMPDIR环境变量：

TMPDIR

如果设置了TMPDIR，则指定要用于的目录   临时文件。 GCC使用临时文件来保存一个输出   编译阶段，用作下一阶段的输入：   例如，预处理器的输出，它是输入   编译器正确。
