编译高通快速the演示应用程序的问题

Question

我遵循了在Qualcomm.I站点上提到的所有步骤，我正在debian (linux)中运行这个示例。但没有成功。

我的控制台日志如下。

如果有人有主意。请回复。提前谢谢..。

Answer 1

我也有过同样的问题

完全按照这个

将lib /libQuickcv.a复制到ndk目录(例如，/arch-arm/usr/lib) )。

在ndk包含目录下创建一个名为include的目录。将inc目录的内容从安装目录复制到您刚才在ndk目录下创建的新目录(例如/arch-arm/usr/include/fastcv) )。

两者都是不同的地点。这就是我犯的错误，我把它们复制到了同一个位置，现在它完美地工作了:-)
