Android 7.0 Build Error

我通过vagrant安装了Ubuntu 16.04。但是，当我运行make Android 7.0时，会发生以下错误。Android 7.0 Build Error

有任何建议或建议吗？

我认为这是为Invalid argument for read-write mmap?

为同一如果一定要使用共享文件夹，请修改编译/工具/ ijar/zip.cc

@@ -994,7 +994,7 @@ ZipBuilder* ZipBuilder::Create(const char* zip_file, u8 estimated_size) {

我希望它是有用的。

格式为err.please修改ZipBuilder :: Create（）方法中的代码：MAP_SHARED - > MAP_SHARED | MAP_ANONYMOUS – user7063108

感谢Jignesh Ansodariya。基本部分是ijar exe在build/tools/ijar/zip.cc中使用mmap。当你在VM上构建AndroidN时，如果文件夹位于共享文件夹中，则会出现关于mmap的错误。您可以在ZipBuilder :: Create（）方法中将代码：mmap（xxx，xxx，MAP_SHARED，xxx）修复为mmap（xxx，xxx，MAP_SHARED | MAP_ANONYMOUS，xxx），我认为它会好的，否则你需要将代码移动到不共享文件夹。不过，我的英语水平很差。 – user7063108
