按照这里的步骤编译应该是没有问题的 https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-android

你看看项目中是不是额外添加了 /home/fangyu/ocr_mobile/1.1.108.0/x86_64/lib/ 的 link 路径，这是不需要的

The latest master branch supports compiling gpu functions without installing vulkan-sdk. You can give it a try. If it doesn’t work, feel free to reopen the issue and post your findings.
