[gdal-dev] packaging gdal for debian

[Tom Parker]

And after reading my own email I guess my next question is:

Do any of your customers actually expect debian packages or an RPM? Mine
freak if I don't deliver an InstallShield setup.exe file packaged project
for winders. The only one who ever codes to gdal/ogr/proj is me. All I need
are *.so/*.dll files for distribution.

Regards,
Tom

Frank,

First off, your gdal/ogr/proj libraries are peachy-keen and I use them a
lot, I work as a subcontractor for several USG contractors and my products
wouldn't be possible without you, cheers! :)

After reading all these posts I wanted to throw in a response/question
regarding gdal/ogr and integration with VTK. Frank may remember last fall I
sent him a personal email informing him I had written a gdal/ogr/proj
wrapper for the AVS/Express visualization system. Since then AVS has tanked
and my customers have all started migrating to the VTK Visualization Toolkit
for their visualization apps.

VTK from www.kitware.com or public.kitware.com provides a tool for cross
platform projects named Cmake (currently 1.4 beta) that it seems would be
ideal for the gdal/ogr/proj/grass/... projects.

You basically provide a list of *.c, *.cpp, *.cxx files, headers, libraries
and hit the OK button. Cmake then builds your project files for you. It
works great on my winders and linux boxes, has anyone else tried it?

Why not use it??, it is released under the MIT license, same as GDAL/OGR
right?

Enlightment is always appreciated.

Paul,

I'm not sure why you say that GDAL doesn't build a shared library. I
assume you mean it doesn't produce a shared library with the usual
naming conventions. Is that right?

After soon initial hesitancy, I am now willing to revise how I build the
shared library to conform when conventions. I won't use libtool for reasons
I have tried to explain before, but I am willing to modify the configure
scripts to build with conventional names, and using -soname and so forth
set things right.

Hopefully we can roll this out as a GDAL 1.1.8 release in the relatively
near future.

Before I go digging for more details tomorrow, can anyone point me to what
I should be using as a link command on Linux?

Also, on the issue of having the separate development package. I am also
willing to separate out an install-slib, install-dev, install-bin and
install-all targets which would do:

install-slib: Just installs libgdal.so.1.x and support shared data.

install-bin: Installs various programs, and requires install-slib.

install-lib: Installs static library and include files.

install-all: Does all of the above.

I am also willing to review how GDAL installs figure out where to put
python.
Currently I used a bunch of custom configure logic to find where python
modules
belong, and try to install there. Often somewhere like
/usr/lib/python2.0/site-packages.
This gets put in the INST_PYMOD macro in GDALmake.opt, which can be
overridden
on the make commandline if need be. But there have been complaints that I
don't
honour --prefix settings for the python install. The problem is that the
python
modules can't work if they aren't installed where python is, unless people
extend
their PYTHONPATH or something. So what exactly do people want, and how will
it
produce a useful install tree?

PS. I run debian, but generally hesitate to install .debs for stuff like
PROJ.4
and GDAL for fear of confusing my local working configuration. I already
have
problems from having an installed copy of stuff in /usr/local and my local
builds
at times. I suppose I ought to setup an alternate bootable root on my
system for
testing stuff like this.

PPS. I would love to see a centralized package of gis/rs related debs
accumulated
somewhere like remotesensing.org. I can provide system access if this is
felt to
be a good idea. Does it make sense to do the same thing for rpms or should
we
leave this to the freegis guys who are already producing rpms for the
freegis CDs
anyways? Is there a redhat/rpm equilvelent to apt-get and co?

PPPS. I think we should have a mailing list or something for discussions of
packaging
of gis/rs related packages for debian. To avoid duplication, and to ensure
that the
various related technologies (GRASS, MapServer, PROJ.4, GDAL, OpenEV) can
work together
properly.

Best regards,
