'find-amu-version' error

On a first use of !Builder to build a Pi ROM, 2Nov19, on selecting ‘Environment’ this error appears.

AMU: *** File 'GNU.gawk' not found ***
AMU: *** 'find-amu-version' not remade bcause of errors ***

Further attempts show this error.

The build however can still proceed.

I see there is current discussion on git around this area.

FWIW the not yet issued Env 1.41 did not resolve this issue. It is falling over before that AFAICS.

@seteval AMU$HasWorkingWildcard <AMU$Version> > 532

I do see other discussion about memory use.

Anyway HTH. It has kept me entertained all morning.

Try Env merge request 2.

To fetch it into a git repository on Unix or Windows:

cd RiscOS/Env
git fetch --force origin refs/merge-requests/*:refs/merge-requests/*
gut checkout refs/merge-requests/2/merge

Try Env merge request 2.

That fixes it. Thanks.

I trip up on that semi regularly, which for me I deduced is caused by the CSD not existing (for example: I used ‘Set directory’ in the Filer then deleted that directory, or set it to a network share that I subsequently dismounted).

Recent-ish versions of StrongEd also get into a mess if you try starting them when the CSD has gone away, giving an error then quitting. Simply setting the CSD to somewhere that does exist and re-running (StrongEd and picking the environment in Builder alike) solves it.

I cannot reproduce this, do you have any more information?

Env 1.42 fixes these build errors. Thanks.
