I'm trying to build a C binary for my Oneplus 3T (LogoInjector) which uses a snapdragon 821 so it's a arm64 device.
When I run:
android-ndk-r13b/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-gcc -I android-ndk-r13b/platforms/android-24/arch-arm64/usr/include -c LogoInjector.v1.4.c lodepng
and copy the compiled binary to /system/bin on my phone I get this error:
sush: /system/bin/LogoInjector: not executable: 64-bit ELF file
I also tried the 32 bit toolchain but then it gives me:
sush: /system/bin/LogoInjector: not executable: 32-bit ELF file
I set the binary's permission to 755 just like all the others in /system/bin
Can anyone help me fix this?
Thanks!

The -c switch is instructing the compiler to perform the compilation only step, skipping the linkage stage, producing an object file and not executable. Invoke the
aarch64-linux-android-gcc -I android-ndk-r13b/platforms/android-24/arch-arm64/usr/include LogoInjector.v1.4.c -o lodepng
command instead. It is possible that you will need to specify some linker options (like libraries to link with) in addition to these parameters.
I met this issue when trying to run an application. Try to run command :"file nameapp". Here I get:
ELF executable, 32-bit LSB arm, dynamic (/system/bin/linker), not stripped.
But my board run command:"file system/bin/sh"
ELF shared object, 64-bit LSB x86-64, dynamic(/system/bin/linker64), for Android 27,BuildID=4a49062467e2958e78ce79839f483302, stripped.
It's different so cannot run. If you want to run it. Get the file with x86-64.
