pixman ndk交叉编译

pixman-arm.c:99:26: fatal error: cpu-features.h: No such file or directory 怎么解决？

[91program]

No such file or directory LZ，你有没有确认这个文件 cpu-features.h 是否存在呢？ 如果存在，则可能是 include 路径设置的问题；如果没有，就没有什么好说的。

[能写程序-会种庄稼]

环境变量设置 _NDK_SYSROOT

export _NDK_SYSROOT=/data/yanglf/tools/arm-linux-androideabi-4.9_android-18/sysroot

然后需要给代码打补丁

以上就是我编译的办法，你自己看着改吧！
