Buildroot external toolchain + parallel builds

Question

Does buildroot external toolchain supports parallel builds ? Meaning I can have multiple builds done on my system referring to the same toolchain folder.

Thanks.

Answer 1

Yes, without any problem. When Buildroot uses an external toolchain, at the beginning of the build process, it creates a private copy of the toolchain sysroot into the Buildroot build directory. The build remains completely isolated from other builds.
