[M3devel] segmentation fault upon ./install-cm3-compiler.sh upgrade

[Neels Janosch Hofmeyr]

Hi lists,

I am trying to install cm3 5.4.0 on Ubuntu 7.10. I know that it worked 
on 7.4, and am doing the exact same steps. I have now tried it with 
cm3-min-...-5.4.0, just as I did last year.

But now, I get this output:

neels at oubantu:~/cm3-build/scripts
$ ./install-cm3-compiler.sh upgrade
cp /usr/local/cm3/bin/cm3 /usr/local/cm3/bin/cm3-5.4.0
cp /usr/local/cm3/bin/cm3cg /usr/local/cm3/bin/cm3cg-5.4.0
Segmentation fault (core dumped)
cp /home/neels/cm3-build/m3-sys/cm3/LINUXLIBC6/cm3 /usr/local/cm3/bin/cm3-
cp /home/neels/cm3-build/m3-sys/m3cc/LINUXLIBC6/cm3cg 
/usr/local/cm3/bin/cm3cg-
cp /usr/local/cm3/bin/cm3- /usr/local/cm3/bin/cm3
cp /usr/local/cm3/bin/cm3cg- /usr/local/cm3/bin/cm3cg

I have done this a second time, making sure everything is cleaned out 
and monitored things. From adding a `set -x' in the 
install-cm3-compiler.sh, it becomes obvious that `/usr/local/cm3/bin/cm3 
-version' exits with a Segmentation Fault.

After doing ./cminstall (the minimal binary install), cm3 -version said
$ /usr/local/cm3/bin/cm3 -version
Critical Mass Modula-3 version 5.4.0
  last updated: 2006-10-11
  configuration: /usr/local/cm3/bin/cm3.cfg

After doing ./do-cm3-core.sh buildship, it still said the same.
So, somewhere in install-cm3-compiler.sh, a disfunctional cm3 binary 
gets installed in /usr/local/cm3/bin/, after which cm3 yields only 
segmentation faults.

After install-cm3-compiler.sh, cm3 -version says
$ /usr/local/cm3/bin/cm3 -version

Aborted (core dumped)

Trying to backtrace in gdb apparently doesn't work -- I don't know how 
to compile debugging symbols into it. Giving up.

I think now is the time to remove the statement "[cm3 is] easy-to-use 
[and] easy-to-install" from modula3.elegosoft.com. No piece of software 
I have ever encountered is as difficult to use and as impossible to 
install as critical mass modula3. I *am* following all the instructions!

argh,
Neels
