Hello John,
Again, thanks for your help!!
I think you are on the right track even though the problem hasn't been
solved, yet. This is what happened:
- I checked the content of the modules folder
[root@3-98-237-24-cable stefan]# ls /usr/lib/mol/0.9.63/modules
2.2.17 2.2.19pre7 2.4.11 2.4.18 2.4.4 2.4.7-pre3
2.2.18 2.2.20pre8 2.4.14 2.4.2 2.4.4-6.2mdk 2.4.8-pre2
2.2.19 2.4.1 2.4.16 2.4.3-pre1 2.4.7 2.4.9
[root@3-98-237-24-cable stefan]#
- I changed the etc/molrc file according to your suggestion.
- I tried
[root@3-98-237-24-cable stefan]# startmol
====================================================================
No mol-0.9.63 kernel modules corresponding to the running
2.4.18-0.8a kernel were found ('startmol --list' displays
installed version). Recompile the mol kernel modules (recommended)
or try starting MOL using the '-a' switch. The '-a' flag can be
made default by adding 'allow_kver_mismatch: yes' to /etc/molrc.
====================================================================
[root@3-98-237-24-cable stefan]#
- I tried startmol -a only to experience my first ever complete freeze
in Linux.
Do you aggree that now needs to happen what you have suggested already:
a recompilation?
I am ashamed to admit that I have no idea how to do that. I am that new
to Linux. How and what do I recompile in order to make mol work on my
computer?
Thanks!
Stefan
