Make继续使用原生gcc而不是Android NDK

Question

First of all, I know only basics about makefile and I'm new to Android NDK.

I've got x64 Linux Mint 17.1 and Android NDK r8e , and I'm trying to build NetHack for Android .

As stated in README , basic idea is to modify makefile with local Android NDK path:

NDK = /path/to/android-ndk-r8d
SYSROOT=$(NDK)/platforms/android-9/arch-arm
CC = $(NDK)/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc --sysroot=$(SYSROOT)

But I keep getting this error:

cc -m32 -o makedefs makedefs.o ./monst.o ./objects.o /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc.a when searching for -lgcc

Apparently /usr/bin/ld is being used instead of arm-linux-androideabi-ld and it doesn't look for libgcc.a in Android NDK folder. Am I missing some environment variable or make argument?

Thanks.

Here's complete output:

UPD2

Apparently installation instruction isn't complete. For some reason util folder is not build using Android NDK gcc, but with system default cc . After installing following packages:

• gcc-4.6
• gcc-4.6-multilib
• gcc-arm-linux-androideabi

I've set system default gcc version to 4.6 using update-alternatives . And it solved my issue.
