我想将VXL（Vision-something-Libraries）移植到android平台。我使用的交叉编译器是android-cmake。您可以从网址http://vxl.sourceforge.net/获取 VXL。 我使用的版本是 vxl-1.14.0 您可以从网址http://code.google.com/p获取 android-camke /android-cmake/

当我为cmake正确设置我的NDK，并指定独立工具链作为android-camke的引入。然后，我使用andriod-camke编译VXL。但是我遇到很多错误。它无法生成Makefile。有人知道为什么吗？

接下来是错误日志。

正如 Andrey 的评论所提到的，VXL 使用 CMake 的方式可以防止交叉编译。然而，还有一个替代方案。其中一位维护者维护包含核心库的替代构建系统的分支。分支应该是修改以使用交叉编译器的vxl-build-makefiles良好起点。

http://sourceforge.net/p/vxl/svn/36716/tree/branches/vxl-build-makefiles/

如果您对使用分支有任何疑问，或者对 VXL 有任何疑问 - vxl 邮件列表可能更有用。vxl-users@lists.sourceforge.net
