# ngspice build script for MINGW-w64, release or debug version, 64 bit
# compile_min.sh

#Procedure:
# Install MSYS2, plus gcc 64 bit, libtool, autoconf, automake, bison, git, and make
#     See either https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2
#     (allows to generate either 32 or 64 bit executables by setting flag -m32 or -m64)
# start compiling with
# './compile_min.sh' for release or './compile_min.sh d' for debug version.

# Options:
# CIDER may be selected at will.
# XSPICE, OpenMP, OSDI, and KLU may be deselected. if not required.
# --enable-oldapps will make ngnutmeg ngsconvert ngproc2mod ngmultidec ngmakeidx in addition to ngspice

# ngspice as console app:
# Install readline, ncurses
# Remove --with-wingui in line ../configure ... .
# It might be necessary to uncomment and run ./autogen.sh .

# ngspice as shared library:
# Use compile_min_shared.sh
