Can't build the library about ffmpeg-android

[thealban]

would be great if someone could help on this I need the newest version but I can't build the project

[johnmurphy01]

I had to update my NDK ABI version to 4.9(the default is 4.8). I also had to update my android version to something other than the default(which is 9). I updated my version to 23. All of this can be done from within the settings.sh bash file. I am running into other issues but this got me past the C compiler and toolchain errors.

My issue is within x264. Whenever I run the bash script to compile x264, I get the following in the logs:

checking for pthread_create(0,0,0,0); in pthread.h... no
Failed command line was:
---------------------------------------------------------
/home/john/repos/ffmpeg-android/toolchain-android/bin/arm-linux-androideabi-gcc conftest.c -Wall -I. -
I$(SRCPATH) --sysroot=/home/john/repos/ffmpeg-android/toolchain-android/sysroot -std=gnu99 -
lpthread --sysroot=/home/john/repos/ffmpeg-android/toolchain-android/sysroot -lm -o conftest 
androideabi/4.9.x/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lpthread
collect2: error: ld returned 1 exit status

There are several more of these similar errors surrounding swscale.h, lpostproc, lavcodec and more
