Maciej Suminski e3a06dca70 Fallback to system ngspice library when libngspice is not found in other paths on macOS 2018-04-19 14:48:31 +02:00
Maciej Suminski 4526f40fe1 ngspice: add extra paths to search for libngspice 
The main purpose of the patch is to load libngspice from macOS bundle.
There are also some additional paths that could make Windows developers
easier.

Maciej Suminski bad462a228 Spice simulator: reload ngSpice dll on error 
ngSpice frequently ends up a simulation with an error:
"Error: ngspice.dll cannot recover and awaits to be detached"
The only way forward is to reload the shared library and
reinitialize ngSpice.

Maciej Suminski 33620ecc85 Revert "libngspice is linked at compile time" 
This reverts commit 75f8b20493.
In case of problems, ngspice demands to be detached which is not
possible when it is linked at compile time.

Maciej Suminski d7e1152aa3 Correct way of freeing memory in NGSPICE class 
Strings created with strdup() should be deleted using free(), not
delete.

Maciej Suminski 2a6b8f153b NGSPICE as a singleton 
One cannot call ngSpice_Init() twice without unloading the dll. When calling
ngSpice_Init, we pass a pointer to a NGSPICE instance and thus it cannot be changed.
When any of the callback function is called with a stale pointer everything crashes.

Maciej Suminski 9f3324bac7 Changed the way ngspice is executed Previously it was run in a wxThread, but it did not allow to issue commands while the simulation is running. If you check ngspice shared library source code, then you will discover "bg_*" commands that executes commands in background, so the simulator still can be controlled. 2016-08-11 14:41:19 +02:00
