Cross compiling static C hello world for Android using arm-linux-gnueabi-gcc

Question

I want to build a static hello world from C using arm-linux-gnueabi-gcc as opposed to using the NDK standalone toolchain or Codesourcery for that matter.

In Ubuntu..

Answer 1

Try specifying the architecture/cpu. It sounds like the compiler is creating code with a higher architecture version than the emulator can handle.

This might work:

arm-linux-gnueabi-gcc -static -march=armv5 hi.c -o hi

Answer 2

It worked for me with CodeBench compiler on ubuntu desktop. https://sourcery.mentor.com/sgpp/lite/arm/portal/release2029

Just create a static binary with this command:

arm-none-linux-gnueabi-gcc -o hello -static hello.c

then push it to phone

adb push hello /data/local/tmp

go run it:

adb shell
$ chmod 755 /data/local/tmp/hello
$ /data/local/tmp/hello

This will print Hello World on terminal. Same can be done from phone also. Use terminal emulator or SL4A bash shell to execute.

As far as I know, you cannot run user-land applications within Android that are not compiled with some form of gcc-arm-linux-androideabi.

Answer 4

If I do this on a Debian machine (VM in my case), all seems well. I am not sure what when wrong with doing similar on ubuntu. It could be as Leo suggested, but I cannot confirm. This should work for you though.

Someone added this link, but it is not using the toolchain I mentioned in the description. Leaving it in case anyone is interested.

Answer 5

Your code actually works for me.

I compiled it on Ubuntu and push it to /data/local/tmp

And then chmod 777 hi

Finally it works well.

Answer 6

Did you check the permissions of the data folder ? Try using the local instead ! You can just use adb shell and then cd into the folder where the executable was pushed and try ./hi. I guess this is just a permissions issue
