# ngspice build script for Linux, release or debug version, 64 bit
# compile_linux.sh <d>

# Procedure:
# Install gcc, bison, flex, libtool, autoconf, automake, 
# libx11 and libx11-dev (headers), libXaw and libXaw-dev, libreadline and dev
# xmu, xet, xt, libxft, libxrender, libfreetype, libfontconfig
# for details please see the ngspice manual, chapt. 32.1.
# Declare 'compile_linux.sh' executable and start compiling with
# './compile_linux.sh' or './compile_linux.sh d' from the ngspice directory.
#  Centos users may need to add -std=c99 to the CFLAGS in the ../configure
#  statement.
# Options:
# --enable-osdi will enable the OSDI interface, which, in conjuction with the
# external OpenVAF Verilig-A compiler, will allow access to advanced compact
# device models writen in Verilog-A.
# Please see the ngspice manual, chapt. 13, for more info on using OSDI/OpenVAF.
# CIDER, XSPICE, and OpenMP may be selected 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 .
