Hi, I got a bug report [1] for KiCad in Debian testing/unstable because of a not working ngspice based simulation in eeschema.
I was first searching for the reason why the packaging isn't detecting that the assumed library libngspice.so.0.0.0 was detected as a dependency. The bugreporter stated that he is needed the package libnsgpice0-dev to get eeschema working with simulation. So I tried around this information and the reporter is right. If I start eeschema without this package installed I get an error message that libngspice.so was not found. This is an error in my eyes because eeschema is not looking for the needed library with the API version it's build against. As libngspice is using a API version 0 the correct library to look for would be libngspice.so.0 and not libngspice.so that is normally a symlink to the most recent version of the library and only used while linking. Thus we ship -dev packages in Debian with a symlink of a file libfoo.so to full versioned named library. For libngspice0 this looks like this: > $ ls -l /usr/lib/x86_64-linux-gnu/libngspice.so* > lrwxrwxrwx 1 root root 19 Okt 15 19:50 > /usr/lib/x86_64-linux-gnu/libngspice.so -> libngspice.so.0.0.0 > lrwxrwxrwx 1 root root 19 Okt 15 19:50 > /usr/lib/x86_64-linux-gnu/libngspice.so.0 -> libngspice.so.0.0.0 > -rw-r--r-- 1 root root 7091024 Okt 15 19:50 > /usr/lib/x86_64-linux-gnu/libngspice.so.0.0.0 > $ dpkg -S /usr/lib/x86_64-linux-gnu/libngspice.so > libngspice0-dev:amd64: /usr/lib/x86_64-linux-gnu/libngspice.so $ dpkg -S /usr/lib/x86_64-linux-gnu/libngspice.so.0.0.0 > libngspice0:amd64: /usr/lib/x86_64-linux-gnu/libngspice.so.0.0.0 So looking manually at the binaries build from the kicad source by ldd I can see a lot linked libraries but no library libngspice.so.0! Seems the library is simply opened by dlopen. So that's the reason why the packaging isn't adding a dependency on the package libngspice0.
