I disagree, the libngsice0 package is only containing the shared libray parts and if the libary would use some external things without depending on it would be programmed in a bad way. $ dpkg -L libngspice0 /. /usr /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/libngspice.so.0.0.10 /usr/share /usr/share/doc /usr/share/doc/libngspice0 /usr/share/doc/libngspice0/changelog.Debian.gz /usr/share/doc/libngspice0/changelog.gz /usr/share/doc/libngspice0/copyright /usr/share/lintian /usr/share/lintian/overrides /usr/share/lintian/overrides/libngspice0 /usr/lib/x86_64-linux-gnu/libngspice.so.0 While the ngspice package is containing the files you mentioned. $ dpkg -S /usr/share/ngspice/scripts/spinit ngspice: /usr/share/ngspice/scripts/spinit $ dpkg -S /usr/lib/x86_64-linux-gnu/ngspice/* ngspice: /usr/lib/x86_64-linux-gnu/ngspice/analog.cm ngspice: /usr/lib/x86_64-linux-gnu/ngspice/digital.cm ngspice: /usr/lib/x86_64-linux-gnu/ngspice/spice2poly.cm ngspice: /usr/lib/x86_64-linux-gnu/ngspice/table.cm ngspice: /usr/lib/x86_64-linux-gnu/ngspice/xtradev.cm ngspice: /usr/lib/x86_64-linux-gnu/ngspice/xtraevt.cm > * running software used libngspice0 without ngspice installed may results in > error "MIF-ERROR - unable to find definition of model and Simulation > interrupted due to error!" (with previous warning "Warning: can't find the > initialization file spinit") The ngspice binary isn't even depending on any symbol from libngspice libary so dpkg-shlibdeps isn't filling in the library as an dependency. https://packages.debian.org/unstable/ngspice If there is a symbol from there needed then this needs to get fixed upstream. But I'm sure this isn't the case here. Maybe Holger (CCed) can give a better explanation. > * running software used libngspice0 with installed ngspice in version > different > than libngspice0 version (for example libngspice0 43+ds-1~bpo12+1 and ngspice > 39.3+ds-1) may cause segmentation fault. You do not provide an example where we could prove your assumption. Without it's impossible to re-adjust a potential misbehavior. > Segmentation fault occurs only while referring to standard models provided by > *.cm files, for example while simulating digital systems using: > > A1 [in1 in2] out AND > .model AND d_and You might provide what you try to do in detail, Holger can then have a look at this. Holger, I assume you are interested in some samples so you could have a look at? Thanks! Regards Carsten
