Installation
============
LINUX
-----
Either install RPM packet with binaries, or compile as described in the
UNIX section
UNIX
----
1. Extract package with gzip -dc g2-xxxx.tar.gz | tar xvf -
2. Run './configure'
3. Run 'make depend'
4. Optionally edit src/g2_config.h to fine-tune g2 behavior (only if
you know what are you doing)
5. Run 'make'
6. Run 'make install' or copy libg2.a and g2.h, g2_X11.h, g2_gd.h, and
g2_PS.h to the default locations for library and include files.
7. cd to demo directory and run 'make demo' to compile demo
applications
8. To rebuild documentation run 'make doc' (html, PS and pdf manual
should be already included into documentation).
WINDOWS NT
----------
1. Extract package: unzip 'g2-xxxx.zip'
2. For gd support, please download the binary gd version and place it in a
folder next to g2 using default folder name gdwin32, i.e. it is expected
in ../gdwin32 from the folder this file is residing.
You also will need to create the bgd.lib file using makemsvcimport.bat
3. MS Visual C++ users can build both library and demos with the supplied
project file: g2.xxx
users of gcc or other commandline based compilers with make support
continue as in Unix example
VMS
---
Note: VMS is not tested in latest builds. However descrip.mms is a
good starting point.
1. set default to root of distribution directory
2. type mms to build g2.olb library
3. to compile demo files, set defualt to [.demo] and type mms
4. to install: copy g2.olb and g2.h, g2_X11.h and g2_PS.h to install
directories
PNG-SUPPORT
-----------
g2 needs to be linked to the free available gd library written by
Thomas Boutell in order to create PNG files. g2 is tested with
version 2.0.22 of gd. gd is available at http://www.boutell.com/gd/ and
at numerous mirror sites. Use a ftp search
(e.g. http://ftpsearch.ntnu.no/) and search for "gd1.3.tar.gz" to find
your nearest mirror site.
PERL SUPPORT
------------
1. build g2 library
2. cd to g2_perl and run
perl Makefile.PL
make
make test
SHARED LIBRARIES
----------------
Support for shared libraries is tested on Linux and OSF
(DigitalUnix). To build shared libraries type 'make shared'. If you
want to run demo applications without installed shared libraries, you
should add to LD_LIBRARY_PATH the path to the g2 shared library
(e.g. 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/some/path/to/g2')
