[M3devel] [radugrigore at gmail.com: Re: install problems]

[Stefan Sperling]

Olaf, why did you forward Radu's request to the m3devel
list? Is only elego staff on m3-support? If so, why?

Just in case people missed his response, here it is.

I don't know what his problem could be, may be someone
who has an idea could respond and make it clear that
further replies should go the m3devel list directly?

Thanks.

(Please note that I am not subscribed to this list. I wasn't even
aware that it _is_ a list. I sent an email only because of the note at
the end of the webpage linked above. Oh, you should probably know that
the web form mentioned in the same paragraph on that webpage insists
on "all mandatory fields being filled in" even when _all_ fields are
filled in.)

After
  ./do-cm3-core.sh buildship  // seem to work fine
  ./install-cm3-compiler.sh upgrade
running cm3 crashes every time actually. It just so happened that
  ./do-cm3-std.sh buildship
was the next command that was supposed to be run.

(Might be relevant: the command "./install-cm3-compiler.sh upgrade"
didn't work because I installed cm3 in /homr/rg/tools/cm3 instead of
/usr/local/cm3 and the latter is hardcoded in sysinfo.sh. The same for
the lib directory. It did seem to work after fixing those.)

The backtrace doesn't seem useful:
(gdb) where
#0  0x9e841069 in ?? ()
Cannot access memory at address 0x405fcfa2

It crashes quite fast:
