Anybody compiled from source with ngspice simulator enabled? [linux]

Software

Yes, ngspice is installed.

For some reason the CMake recipe to find it fails. I’ve played with path variables a bit, but without any success.

To have the simulator working, you need libngspice, not ngspice itself. Unfortunately, at the moment a package containing the library is only provided by Arch Linux, so for other platforms it has to be build from source. There is a script [1] that does the dirty job for you and should work on Linux, Windows (mingw64) & OS X. I will add a message explaining the problem when CMake fails.

The script didn’t run without a few modifications:

cd ${SRC_DIR} || ( echo “*** ngspice has not been built yet”; exit 1 )

etc…

But that doesn’t seem to be 100% correct either…

More specifically, this line

cd “${SRC_DIR}” || echo “*** An error occurred when downl… the source code ***”; exit 1

results in

[…]
Checking connectivity… done.

  • ‘[’ 0 ‘!=’ 0 ‘]’
  • cd /tmp/libngspice_so/ngspice
  • exit 1

So the “exit 1” should not be executed.

I have just applied a few fixes and it is building on my two test machines (Arch & Debian). Can you try to download the script again? What is your shell?

GNU bash, version 4.2.53(1)-release (x86_64-suse-linux-gnu

Wrapping in (…) puts stuff into a subshell. This doesn’t work nicely here, sorry. “exit 1” only exits the subshell, but doesn’t terminate the script.

This version appears to behave on my system. More text though.

Thank you madworm. I have just updated the script to include your changes.

Seems to work on OS X 10.11 (El Capitan) as well. Quite a few warnings but no errors.
