Circuit simulation

Lev All Messages By This Member #22515 Dear List, When I try to do circuit simulation, I get the following error: Missing ngspice shared library and libngspice.so.0.0.0: Cannot open shared object file: No such file or directory. I've compiled ngspice locally, and installed to /usr/local. Then compiled KiCad, and it dinds ngspice libraries in /usr/local/. If I set LD_LIBRARY_PATH, it works. I've read that others move the libraries to /usr, what I don't want to do. Is there any way to explicitly tell KkiCad where to search for the libraries? Thanks, Levente
ng10066504jan All Messages By This Member #22516 What operating system are you using, and what version of Ki-Cad? (Don't get hopes up... I still won't know answer... but if you supply that info, someone else may be quicker to respond.)

Lev All Messages By This Member #22517 Oh yes, sorry I forgot this. Debian stable, KiCad 5.1.4, ngspice-31 Thanks, Levente On Thu, Nov 7, 2019 at 4:35 PM ng10066504jan via Groups.Io <ng10066504jan@...> wrote: What operating system are you using, and what version of Ki-Cad?

Lev All Messages By This Member #22520 When compiling KiCad, cmake says it finds libngspice in /usr/local/lib. So I don't understand why it can't find it. Even KiCad's shared objects is located in?/usr/local/lib. toggle quoted message Show quoted text On Fri, Nov 8, 2019, 00:53 G.Dragon <tregare@...> wrote: Sorry, library path shell variable?

G.Dragon All Messages By This Member #22521 I never assume that it will actually find anything;). Too bloody many times I’ve come across issues with software compiled on Unix and Unix like systems. toggle quoted message Show quoted text On Thu, Nov 7, 2019 at 9:30 PM Lev <leventelist@...> wrote: When compiling KiCad, cmake says it finds libngspice in /usr/local/lib.

[email protected] All Messages By This Member #22522 I don't have any plain debian systems to confirm with, as my boxen are generally ubuntu variants, but they don't typically stray TOO far from debian. I assume the ngspice library is actually in /usr/local/lib , correct? check the files/etc/ld.so.conf and if the directory exists, the files inside /etc/ld.so.conf.d/ One of these files should contain the line /usr/local/lib If none of the files include the line, add it to /etc/ld.so.conf (or read the man page for ldconfig for how to properly add it to a file inside /etc/ld.so.conf.d/ ) run? sudo ldconfig The program ought to be able to find it then.

[email protected] All Messages By This Member #22524 If you run ldd against the kicad executable, it should give you a report on which libraries it's pulling in for each of the dependencies. does that give you anything useful?

It doesn't list ngsipce library, hence it is loaded dynamically at runtime.
