构建JOGL在c.build.nativewindow.awt过程中出现gcc错误: jawt.dll:文件无法识别:文件格式无法识别

Question

我构建了Ant，并且我正在使用它来构建JOGL。在这个版本中，我恢复到了java 1.8。我安装了MinGW32，我可以使用gcc。我用ant构建了gluegen，它就像一个护身符。在一个干净的构建中，在jogl中做同样的事情会得到以下日志(缩写)：

我运行的是Windows 10，Ant 1.10.5。我知道“文件格式不被识别”错误意味着

Answer 1

好的，我在发完这篇文章后马上就明白了。我使用的是MinGW32，而我本应该使用64位替代方案。切换到MinGW64后，构建成功。
