Re: Toybox make root no longer works as expected

Hey Adrian,

Can you do a --version on that toolchain gcc for me please.  Overflow and internal compiler error suggest maybe -mj2 is not in the command line, for instance.

In the meantime, here is the (IIRC current) build script we use to generate toolchains for J-Core J2 J1 Linux and bare metal.  It’s a but convoluted, patches on patches… no one has the time to clean this up as we’d like.

Cheers,
J.
