Sys / fcntl.h: no such file when pcsclite cross-compiled for Android?

Question

everything: I am making an Android application that can commnicate with ccid a smart card reader from android mobile, I chose this path: "pcsc-lite-1.8.5 + ccid-1.4.7 + libusb-1.0.3", which works Ubuntu (Linux OS on PC) is very good. then I tried to transfer them to android, there are a lot of problems when cross-compiling. most of these problems are that the Android Bionic library lacks headers and functions, for example:

• sys / fcntl.h, mqueue.h: no such file;

• pthread_cancel: undefined link;

and now when I cross-compile pcsclite to create the pccd executable, I got this error:

sd-daemon.c: 35: 23: fatal error: sys / fcntl.h: no such file or directory

Android.mk:

Many of the Android headers are not in the standard layout. You can use the following command to search for the NDK to locate the missing find . -name fcntl.h files find . -name fcntl.h find . -name fcntl.h . It looks like include <sys/fcntl.h> needs to be changed to include <fcntl.h> .

There is no pthread_cancel Android library pthread see "docs / OVERVIEW.html". It is easy to replace pthread_cancel .

I'm not sure what to do with mqueue .
