我在编译 libqxt 时遇到以下问题。

configure.bat 生成文件，但显示一些警告：

   Makefiles generated. Run mingw32-make now.

mingw32-make 几乎立即中断，但有一个例外：

c:\Users\Lukasz\Downloads\libqxt-libqxt-7e0d3396b765>mingw32-make
mingw32-make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x421963)

源码是从官网下载的。运行 configure 和 mingw32-make 是 README 文件中描述的编译方式。这里有什么问题？

答案很简单而且出乎意料 - mingw32-make 在 PATH 环境变量中的括号（“（”符号）存在很大问题。解决方案是从 PATH 中删除所有包含“（”的目录。

可以使用语法在命令行中本地更改 PATH（而不是为任何其他程序更改它）： set PATH=...例如，我清理过的 PATH 是：

set PATH=C:\QtSDK\mingw\bin;C:\QtSDK\Desktop\Qt\4.8.0\mingw\lib;C:\QtSDK\Desktop\Qt\4.8.0\mingw\bin\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;

至于获取当前 PATH 值，请使用语法：echo %PATH%.
