Re: [ptxdist] Gdb debugging helper [PATCH]
Hi Tim Thanks for the advice. Just to be sure. Python was not enabled (default) then as the helper? Could it be I was correct? So then I need to rebuild the toolchain, with Python enabled (example below)? Or is there a quick hack for me to try without rebuilding the toolchain, cos then I have to rebuild everything and I just want to quick test if this is the solution.
