cross-compiler

These scripts will build a cross-compiler toolchain for the Drobo ARM devices which will be 32 or 64-bit based on the build machine.

A 32-bit build machine will result in a toolchain with the prefix arm-drobo_i686-linux-gnueabi.

A 64-bit build machine will result in a toolchain with the prefix arm-drobo_x86_64-linux-gnueabi.

DroboApp scripts can abstract the build machine platform by using arm-drobo_$(uname -m)-linux-gnueabi.

The cross-compiler default install location is /home/drobo/xtools/toolchain/arm-drobo_$(uname -m)-linux-gnueabi.

Please look at the releases page for ready-to-use downloads.

How to build the cross-compiler toolchain

• Have a machine with Docker installed
• Clone this repository locally
• Build the Docker cross-compiler builder container: docker build -t droboports/compiler_builder ./src/Dockerfile
• Use the Docker container to build the cross-compiler toolchain: docker run --rm -ti -v $PWD:/home/drobo/build/compiler droboports/compiler_builder /home/drobo/build/compiler/build.sh

There will be a file called arm-drobo_i686-linux-gnueabi.tar.xz or arm-drobo_x86_64-linux-gnueabi.tar.xz in the same folder.
