Objective
This HOWTO describes the process to modify a release compatible FGS package.
Introduction
For this purpose, the FGS development team prepares the release builds in a
VMWare virtual machine and makes a copy of that virtual machine available for
every release. Note that this virtual machine is not available yet.
Package building process
To modify an existing package or add a new one, the following steps must be
executed:
1) Download the virtual machine from the Maptools Web site
(http://maptools.org/fgs/index.phtml?page=downloads.html)
2) Start the virtual machine player.
3) Log in to the virtual machine (username: fgs, password: fgs-dev).
4) Modify the target FGS package.
5) The fgs-dev build environment is installed in /home/fgs/fgs-dev. Set the
environment. To do so go into the fgs-dev root directory and execute
". setenv.sh".
6) Build the package by issuing the "fgsdev build_pkg fgs_package" command.
7) Install the package or re-install the modified package in your fgs
environment.
8) Come back to the fgs-dev environment to fix any issues that were met
when the package was used in the fgs environment. Go back to step 5 or
if everything behaves as you expected you are done.
10) If you want to contribute a new package to the FGS project and make it
available to all users in a future release, please submit your package
idea for discussion and to gauge interest on the FGS mailing list
(http://maptools.org/fgs/index.phtml?page=mailinglist.html)
Example:
Suppose we want to add MrSID image format support in GDAL, we should follow the
above steps from 1 to 4. We need to modify the fgs_build file, in step 5, by
uncommenting the following line:
#OPTIONS="$OPTIONS --with-mrsid=$FGS_DEV_HOME/src/Geo_DSDK-6.0.7.1407"
Then we build the GDAL package by executing "fgsdev build_pkg gdal". If
everything goes well we should have a new fgs-gdal-base-x.y.z-linux-i386.tar.gz
tar ball.
We install or reinstall the GDAL package in our fgs environment and we proceed
with testing. We need to go back to step 5 if there is any issue with the
package.
That's it.
