On the above link, there are no instructions on how to compile an AArch32 application with the AArch64 compiler. You need an AArch32 gcc (e.g. arm-linux-gnu-gcc, not aarch64-linux-gnu-gcc). > I saw there are aarch32 support in arm64 kernel porting. Yes, that's to support AArch32 binaries (ARMv8/v7/...). > Would you mind to let us know how to get aarch32 ELF for running on > ARM64 processors? Just use the right compiler. > PS:Below is my compile error message: > #aarch64-linux-gnu-gcc -mabi=ilp32 test.c -mabi=ilp32 is entirely different from an AArch32 compiler. The above still generates AArch64 but with the ILP32 ABI (sizeof int/long/pointer is 32-bit). -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
