NGSpice Error: unable to load libraries
Last modified: 2008-04-22 18:36:19 EDT
Description of problem:
When running ngspice, it is unable to load its component libraries. Below is
the output when the command ngspice -b test.cir is run:
/usr/lib/spice/spice2poly.cm: undefined symbol: spice2poly_info
Error: Library /usr/lib/spice/spice2poly.cm couldn't be loaded!
/usr/lib/spice/analog.cm: undefined symbol: cm_climit_info
Error: Library /usr/lib/spice/analog.cm couldn't be loaded!
/usr/lib/spice/digital.cm: undefined symbol: cm_adc_bridge_info
Error: Library /usr/lib/spice/digital.cm couldn't be loaded!
/usr/lib/spice/xtradev.cm: undefined symbol: cm_aswitch_info
Error: Library /usr/lib/spice/xtradev.cm couldn't be loaded!
/usr/lib/spice/xtraevt.cm: undefined symbol: ucm_d_to_real_info
Error: Library /usr/lib/spice/xtraevt.cm couldn't be loaded!
Below is a listing of /usr/lib/spice:
-rwxr-xr-x 1 root root 11664 2007-08-24 18:37 analog.cm
-rwxr-xr-x 1 root root 12120 2007-08-24 18:37 digital.cm
-rwxr-xr-x 1 root root 10920 2007-08-24 18:37 spice2poly.cm
-rwxr-xr-x 1 root root 11316 2007-08-24 18:37 xtradev.cm
-rwxr-xr-x 1 root root 11172 2007-08-24 18:37 xtraevt.cm
I have also attached a copy of test.cir; please note, however, that these error
messages occur for any file that I try to simulate (including the example ones).
This error leaves me unable to do any simulations.

Not sure - this is just the standard installation from the repos - it hasn't
worked since it was installed. Below is some info about my system:
Linux localhost.localdomain 188.8.131.52-12.fc8 #1 SMP Tue Feb 26 14:58:29 EST 2008
i686 athlon i386 GNU/Linux
Steps to Reproduce:
Created attachment 299781 [details]
Simple test circuit to make sure that ngspice simulates properly
I have also seen this issue on the x86_64 version of ngspice for F8.
Rebuilding the rpm on a fully updated system fixed the problem for me.
I managed to fix this on my system by recompiling the source and then manually
installing it (make install) - then Ii had no problems. Must be something in
the distributed rpm.
I'll fix it as soon as possible.
Sorry for the delay, I'm having some problems with my pgp key to commit.
