This is a attempt to compile GCC to run on Android (ARM)

Im trying compile the GCC and G++ to run inside Android to compile inside Android the .c and .cpp files.

Instructions

git clone git@github.com:prsolucoes/gcc-for-arm.git
cd gcc-for-arm
./build.sh

Obs: You need docker to use it

Test

After build with success, you can execute:

./run.sh

And inside the container, you can run:

file [path-to-the-new-gcc]

And see if show ARM on file arch

Obs: You need docker to use it

Issues

When i run the script "build.sh" it make everything but not build the GCC, see the error:
