我正在尝试使用 JDK 1.7.0 和 JavaCpp 0.3 (bin) 在 Windows XP Professional (x86) 上使用 Visual Studio 2008 构建和运行 JavaCpp 的 LegacyLibrary Example,我得到以下输出。错误出现在最后一个命令 java -cp javacpp.jar LegacyLibrary 上。

最佳答案

问题是 Visual Studio 2005 和 VS 2008 不会自动链接到 VC++ 的内部库。解决方案是将 list 与可执行文件中所需的库捆绑在一起,如所述here ,或者简单地使用 Visual Studio 2010 或更新版本。我使用 VS 2010,我可以验证该示例现在是否按预期运行。如果您碰巧尝试捆绑 list ,请评论其他人以确认它是一个有效的修复。
