compile_macos_gcc.sh

#!/bin/bash
# ngspice build script for macOS, release or debug version, 64 bit
# compile_macos.sh <d>
# tested with macOS BigSur 11.7.9, MacBook Air i5

# Procedure:
# Install gcc, bison, flex, libtool, autoconf, automake,
# libx11 and libx11-dev (headers), libXaw and libXaw-dev, libreadline and dev
# XCODE and commandline tools
# Declare 'compile_macos_gcc.sh' executable and start compiling with
# './compile_macos.sh' or './compile_macos.sh d' from the ngspice directory.
# Options:
# KLU, OSDI, XSPICE, and OpenMP may be deselected at will.
# --disable-debug will give O2 optimization (versus O0 for debug) and removes all debugging info.

# ngspice as shared library:
# Replace --with-x by --with-ngshared in line ../configure ... .
# Add (optionally) --enable-relpath to avoid absolute paths when searching for code models.
# It might be necessary to uncomment and run ./autogen.sh .
