# ngspice build script for MINGW in MSYS2, release or debug version, 64 bit
# compile_min_shared.sh

#Procedure:
# Install MSYS2, plus gcc 64 bit, bison, flex, autoconf, automake, libtool 
#     See https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2
# start compiling with
# './compile_min_shared.sh' for release or './compile_min_shared.sh d'
# for debug version of shared ngspice

# Options:
# --adms and --enable-adms will install extra HICUM, EKV and MEXTRAM models via the 
# adms interface.
# Please see http://ngspice.sourceforge.net/admshowto.html for more info on adms.
# CIDER, XSPICE, and OpenMP may be selected at will.
# --disable-debug will give O2 optimization (versus O0 for debug) and removes all debugging info.
# To obtain a 32 bit executable, replace -m64 by -m32 ./configure lines.

# Add (optionally) --enable-relpath to avoid absolute paths when searching for code models.
# It might be necessary to uncomment and run ./autogen.sh .
