Rebuilding arm-gnu-toolchain-12.3.rel1 from sources

Codewiz

Where can I find the top-level build scripts used to produce the binary toolchains?

I cloned the latest ABE and downloaded the manifests and the copy_nano_libraries.sh script, but I can't build a 100% equivalent toolchain. In particular, the various newlib variants seem to be built with different cflags, leading to larger static binaries.

I found other minor differences caused by configure finding (or not finding) optional dependencies. Would be good to specify the exact build environment used by ARM.com, for example by publishing a Dockerfile or a VM image.

    Hi Codewiz,

    You're right that the ABE manifest don't capture all the flags and so it's impossible to currently build a bit identical toolchain using it.

    We are currently working to release our internal build scripts for building the toolchain but I cannot give an ETA at this time.

    We are trying to upstream these as soon as possible.
