unknown CPU architecture

Hi, Guys,

I compiled a shared object using mali GPU. But when linking it to produce an application I got an error:.../libGLES_mali.so:unknown CPU architecture.The CFLAGES is -mcpu=cortex-a15 -O2.

What's wrong? I need some help.

Best Regards!

Aha, Pete's message made me do a bit more digging. The SoC you pulled that lib from is 64 bit, i.e. AArch64, so that explains why the arm-linux-androideabi compiler does not recognise the architecture...

In addtion, today I exchanged the gcc version to an x64 version (android-ndk-r10c/toolchains/aarch64-linux-android-4.9/prebuilt/windows/bin/aarch64-linux-android-gcc-4.9)
Note that that is a compiler for the 64-bit version of the ARM architecture (i.e. it emits 64-bit binaries for ARM), not an x64 host 32-bit compiler.
HTH,
Pete
