我试图在Windows XP Professional(x86)上使用JDK 1.7.0和JavaCpp 0.3(bin)在Visual Studio 2008上构建和运行JavaCpp的LegacyLibrary Example,并且得到以下输出。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 文件与可执行文件中所需的库 bundle 在一起,如here所述,或者仅使用Visual Studio 2010或更高版本。我使用了VS 2010,可以验证该示例现在是否按预期运行。如果您碰巧尝试 bundle list ,请为其他人发表评论,以确认它是有效的修复程序。
