The current setup (ngspice.exe) has been tested with MSVC 2022 and CYGWIN on Windows 11.
|
|
A setup for KiCad (MS Windows) is available.
|
|
|
|
64 bit libsndfile has been downloaded from https://github.com/libsndfile/libsndfile/releases/
|
|
|
|
64 bit libsamplerate has been downloaded from https://github.com/libsndfile/libsamplerate/releases

Compiling for MS Windows, 64 bit, with VS2022 or VS2026:
|
|
Download https://github.com/libsndfile/libsndfile/releases/download/1.2.2/libsndfile-1.2.2-win64.zip
|
|
Expand libsndfile-1.2.2-win64 into same level as ngspice, rename the directory to libsndfile.
|
|
Download https://github.com/libsndfile/libsamplerate/releases/download/0.2.2/libsamplerate-0.2.2-win64.zip
|

Compiling for macOS M2 requires installing libsndfile and libsamplerate from Homebrew.
|
|
compile_macos_clang_M2.sh has been enhanced by adding
|
|
-I/opt/homebrew/opt/libsndfile/include -I/opt/homebrew/opt/libsamplerate/include
|
|
to CFLAGS and
|
|
-L/opt/homebrew/opt/libsndfile/lib -L/opt/homebrew/opt/libsamplerate/lib
|
|
to LDFLAGS
|
|
|
|
Linux Ubuntu 24.04 has the libraries libsndfile0 and libsamplerate0 available automatically.
|
|
You may need to install (with apt) the development header files libsndfile0-dev and libsamplerate0-dev.
