UCOSP: status report #13
Wednesday, November 18, 2009
I have successfully built the code checked out from Geospatial,
with the dependencies of xerces 2.8 headers, libraries, jam, pax, and pam-devel, GEOS 3.2.0 libraries on Debian as a non-root user.
As I was running runbuild.sh, I ran into problems about the build script could not pick up some libraries(GEOS, LD) on the fly. It turned out to be the case that the path variables are runtime variables, it doesn't influence the linker. In another words, the path variables tell the build script where to find libraries when then are running, while the linker varibales tell the build script where to find the library when it's linking. The most updated code is adjusted such that it simplifies the process for non-root user to compile code.
Before running runbuild.sh, a non-root user need to:
export GEOS_LOC="/path/to/geos-3.2.0rc1/lib"
export GEOS_INC="/path/to/geos-3.2.0rc1/include"
export LD_LIBRARY_PATH=$GEOS_LOC:$LD_LIBRARY_PATH
Besides, if you are not using default libraries, such as using xerces 2.8 instead of 2.7, you need to put the following line to $INC_ROOT/src/tools/port/jam/bldenv
export XERCVERS=28
Chuck Thibert has provided me with a patch which comes with the adjustment for non-root users to start my first try to apply a patch. Alex Trofast and Andrew Ross also provided me with a diff that serves as a guide for me to go through the proper process of building a patch.
Now that I have already applied the patch from Chuck and successfully build Geospatial code. Next, apply the diff!

A couple of notes when compiling Geospatial with GEOS, GDAL, MapServer
Sunday, November 15, 2009
I have been following this to compile Geospatial under a Debian environment. There are a couple of notes that I want to make
- As of date 2009-11-15, thanks to Frank Warmerdam, the above wiki says "--with-python" under the configuration of GDAL. However, it is still not clear why the python is required for GDAL. Since MapServer does not use it, and ogr2ogr does not require it. And that python extension for GDAL picks up gcc instead of g++ when make is run and to the point of compiling c++ code.
- For the configuration of Mapserver, there is a more detailed description for getting the libraries that Mapserver needs to be build on. That provides the links in 1 place where to get: --with-ogr --with-gd=/usr --with-libiconv=/usr/local --with-png=/usr --with-proj --with-php=yes -with-agg=/usr --with-freetype --with-regex=system
