How to use arm-linux-androideabi compiler

Question

I wonder how to use arm-linux-androideabi compiler. That compiler is on android-ndk tool.

There is ndk-build tool on android-ndk tool. To compile ethercat stack, I need only arm-linux-androideabi compiler.

But, I saw this message.

collect2: ld returned 1 exit status

How am I supposed to do this?

You need to let the compiler know where to look for these files. Try using:

arm-linux-androideabi-gcc --sysroot=/opt/android/android-ndk-r9c/platforms/android-19/arch-arm -o test test.c

where 19 is android API level you want to use. You can find more info on docs/STANDALONE-TOOLCHAIN.html in your ndk dir.
