compile_linux_shared.sh

#!/bin/bash
# ngspice build script for Linux, release or debug version, 64 bit
# compile_linux_shared.sh <d>

# Procedure:
# Install gcc, bison, flex, libtool, autoconf, automake, 
# (not needed for shared library: libx11 and libx11-dev (headers), libXaw and libXaw-dev, libreadline and dev)
# Declare 'compile_linux_shared.sh' as being executable and start compiling with
# './compile_linux_shared.sh' or './compile_linux_shared.sh d' from the ngspice directory.
# Options:
# --enable-osdi will add the osdi interface which allows to dynamically load compiled Verilog-A 
# compact models. Compiling the VA code of the models is done by the OpenVAF compiler.
# Please see the ngspice manual, chapt. 13, for more info on OSDI/OpenVAF.
# CIDER, XSPICE, KLU, and OpenMP may be selected at will.
# --disable-debug will give O2 optimization (versus O0 for debug) and removes all debugging info.

# Add (optionally) --enable-relpath to avoid absolute paths when searching for code models.
# It might be necessary to uncomment and run ./autogen.sh especially if sources have been
# cloned from a git repository.
