Compilation/Installation notes:
(Online version at http://opencircuitdesign.com/xcircuit/install.html)
1) All compile-time features are set during the ./configure process.
Run "./configure --help" for a list of configure options. For most
users, the relevant options are the following:
--with-tcl Configure xcircuit as an extension to Tcl/Tk. Tcl
becomes the default interpreter. Option is mutually
exclusive with "--with-python". A feature of this
version is that the interpreter is available from
the calling terminal concurrently with the GUI.
Another feature of this version is that the graphics
are handled by Tk widgets instead of the troublesome
"Xw" widgets in the distribution. As of version
3.1.7 where most of the bugs have been resolved,
use of this option is highly encouraged.
--with-python Configure xcircuit with the embedded Python
interpreter. Option "--with-python" is disabled
by default, and has no effect if "--with-tcl" has
been selected. The python interface is less
well-developed than the Tcl interface. If you do
not intend to make use of the interpreter
command-line interface, there is probably no reason
to select this.
--prefix=PREFIX Location to install xcircuit. Defaults to
/usr/local/. The executable goes to /usr/local/bin/,
man pages to /usr/local/man/man1/, and everything
else to /usr/local/lib/xcircuit-VERSION/. Defaults
can be separated by explicitly declaring
--exec-prefix=DIR, --mandir=DIR, and --libdir=DIR.
The following option is experimental at present and will be changed to
be enabled by default when the package is deemed stable:
--enable-asg Configure XCircuit with the automatic schematic
generation (ASG) package. This package allows
XCircuit to read SPICE decks and produce schematics
from them. Future functions include reading EDIF
netlists (from Verilog and/or VHDL), and automatially
routing layouts.
The following options are probably not worth messing with:
--disable-lgf Save space by not compiling the compatibility with
"analog" and "diglog" .lgf-format files.
--disable-schema Don't compile the schematic capture system. This
is a major feature of xcircuit, so disabling it is
not recommended. However, you may do so if you
anticipate having no need for circuit netlists.
There are some other options which can be supplied to the "configure"
command-line which should only be needed in rare circumstances. Most
users can ignore these.
--with-tcl=DIR Tcl can be enabled with "--with-tcl" or
"--with-tcl=yes", and the Tcl library and include
directories will be automatically searched. For
Tcl/Tk installations which cannot be found by the
automatic search, DIR should be the directory
containing "tclConfig.sh".
--with-tk=DIR Enabling Tcl for XCircuit implies "--with-tk".
However, for Tk installations which cannot be
found by automatic search and which cannot be
found by specifying "--with-tcl=DIR", DIR should
point to the directory containing "tkConfig.sh".
--with-python=DIR If the configure step cannot find a Python
interpreter, it can be explicitly referenced.
Requires the Python library (libpythonVERSION.a
or libpythonVERSION.so) and the python include
file Python.h. The Python option uses the Python
language as an interpreter for xcircuit.
--disable-double-buffer
This option is almost wholly deprecated due to the
speed of modern processors. However, if you have
problems with slow rendering, you might find it
useful.
--with-xpm=DIR If the configure step cannot find the XPM package,
it can be explicitly referenced. The XPM package
enables the toolbar and an icon when xcircuit is
iconified.
--with-gs=DIR If the configure step cannot find ghostscript,
it can be explicitly referenced. The Ghostscript
option allows any PostScript file to be rendered
on the xcircuit background and saved with the
xcircuit file.
NOTE: When xcircuit went from "imake" to GNU make, the default install
directory changed from /usr/local/lib to /usr/local/share/. Since all
the other CAD tools xcircuit works with install by default to
/usr/local/lib, xcircuit version 3.1 has reverted to /usr/local/lib for
reasons of compatibility. See item (4) below, "uninstall".
2) Compile with the usual GNU-compile steps:
./configure
make
make install
The final step must be done as root if you are installing to default
locations (/usr/local/lib and /usr/local/bin). XCircuit can be run
in test mode before installation (see item (3), below).
For the Tcl/Tk version the make steps are the same, assuming that
Tcl/Tk libraries and include files can be found on the system. If
you specifically *don't* want the Tcl/Tk version, then do:
./configure --without-tcl
make
make install
If you want to test before installing, do the following (csh/tcsh
version; see item (3) for changes to line 4 for bash/ksh/sh):
./configure
make
setenv XCIRCUIT_LIB_DIR ./lib
setenv XCIRCUIT_SRC_DIR ./lib/tcl
lib/tcl/xcircuit.sh
after which, if all goes well, you can do "make install".
3) NOTE: To test xcircuit before installation, set environment variable
setenv XCIRCUIT_LIB_DIR ./lib (csh, tcsh)
setenv XCIRCUIT_SRC_DIR ./lib/tcl
export XCIRCUIT_LIB_DIR=./lib (bash)
export XCIRCUIT_SRC_DIR=./lib/tcl
before running the xcircuit executable.
4) Uninstall:
If you have compiled previous versions of xcircuit, the only thing you
need to do to uninstall these versions is to remove the directory tree
at /usr/local/share/xcircuit-(version) or /usr/local/lib/xcircuit-(version)
for any version numbers which are not current.
5) HP/IRIX users: If the "make" process dies with an error creating the man
page, something like
/usr/ccs/bin/m4:xcircuit.1.m4:911 more than 4096 chars of argument text
be sure to use GNU m4. This can be done during the configure process
(using appropriate substitutions) with the following command:
M4= ./configure [options]
6) 64-bit system users: Proper compile may require specifically using
configure option "--x-libraries=" to point to 64-bit libraries.
This has been fixed for the AMD Opteron under Fedora Core; other
64-bit systems are untested.
-----------------------------------------------------------------------------
Shared Python Library:
NOTE: The XCircuit build will be *much* smaller if you have a shared
python library. However, the build instructions as of Python-2.1c2
don't include instructions for building a shared library under linux.
Here's how you do it:
1) In the Makefile: set
LDLIBRARY=libpython2.1.so
2) Also in the Makefile:
Add a case for libpython$(VERSION).so which looks
exactly like the case statement for unixware:
linux) \
$(LDSHARED) -o $@ $(LIBRARY_OBJS) \
;; \
3) Make until error (can't find libpython2.1.so)
4) Copy or move libpython2.1.so to /usr/local/lib or /usr/lib
5) Run (as root!) ldconfig -v -n /usr/local/lib (or whereever
you just put the shared library) and confirm that it
found libpython2.1.so.
6) Finish "make" (should run to normal completion).
On my system, this is the difference between a 4MB xcircuit executable
and a 1.5MB executable. That's a big difference! Of course, Python
purists would say I should be embedding xcircuit in python, not the
other way around, then what need do I have for a shared library,
anyway?
Python source (and other information relating to Python) can be found
at www.python.org. The Python interpreter is recommended, as XCircuit
eventually will rely on Python to handle writing netlists, for
flexibility in formatting.
-----------------------------------------------------------------------------
Extras:
The file examples/.xcircuitrc shows how to make a home-directory file
to alter the behavior of xcircuit on startup. It shows how to change the
color scheme, add new fonts, override the default libraries, and change
the editing behavior for polygons. Note that if xcircuit is built with
embedded Python, the syntax for .xcircuitrc will be Python syntax, and
may use any Python commands in addition to the commands which hook into
xcircuit functions. The file examples/test.py is a sample Python script
which features use of Python to create animated graphics within the
xcircuit window, shows how to access on-screen elements and change
their properties, and contains convenience function definitions for
manipulating xcircuit elements.
Other files in the examples directory show how xcircuit can be
used to draw various things, from a simple circuit schematic
(vcoblock.ps) to an entire publishable-quality page of music
(prelude.ps), plus an example of a fancy page border for slide
presentations.
The files psfiles/signal.lps and psfiles/musiclib.lps are examples
of alternate or additional object libraries. The library file lgf.lps
is used primarily by the lgf-to-ps conversion routines, but has some
different circuit objects in it.
The file psfiles/fonttest.ps is a short PostScript program you can
use to get your printer to give you the names of all the built-in fonts
that it knows about, which is useful because if you add a font name to
xcircuit, the spelling has to be exactly correct or else the printer
won't recognize it.
The file examples/gettext.py is a sample Python script which adds
a Python command called "gettext(filename)". gettext(filename) reads
in file "filename", which should be an ASCII text file, and turns it
into a label in XCircuit positioned at the cursor position.
-----------------------------------------------------------------------------
X Resources:
The Tcl/Tk version of XCircuit does not use the X resources but
picks up resources from the file "resource.tcl" in the run-time
library path (e.g., /usr/local/lib/xcircuit-3.8/resource.tcl). The
resource names are the same as those described below but are specified
using the Tk "option add" command.
The color scheme of xcircuit has a default setup, but accepts
alternate color schemes using the following keywords which can be put
in the X Defaults (.Xdefaults, .Xresources) file:
Resource name Description Default
------------------- ---------------------------- -------
xcircuit*foreground color of buttons and popups; White
xcircuit*background background of buttons & popups; DarkSlateGray
xcircuit.foreground drawing area foreground; White
xcircuit.background drawing area background; Black
xcircuit*gridcolor color of the grid lines; Gray40
xcircuit*snapcolor color of the snap-to points; Red
xcircuit*selectcolor color of a selected object; Gold
xcircuit*querycolor to differentiate multiple objects; Turquoise
xcircuit*axescolor color of the x, y axes; NavajoWhite4
xcircuit*offbuttoncolor text color of an inoperable button; Gray70
xcircuit*auxiliarycolor text cursor and other things Green
xcircuit*barcolor color of panning bars Tan
A secondary color scheme (for example, black-on-white) can be specified by
adding "2" to each of the above resource names. For example:
xcircuit*foreground2 color of every object drawn; Black
xcircuit*background2 screen background color; White
Other resources accepted by xcircuit are:
xcircuit*width width of the drawing area (pixels); 600
xcircuit*height height of the drawing area; 500
Normally, you will want to put the defaults in /usr/lib/X11/app-defaults.
If you do not have root access, you will want to have them in your own
home .Xdefaults file. If the file is not found by xcircuit, the program
will use its default color schemes, the main one being black-on-white,
and the alternate being white-on-dark-gray.
