Benjamin,
That is indeed confusing, and I'm not entirely sure of the underlying reason
for seeing it in there twice.
But, as a rule of thumb, I would give configure as much information as
possible ... Better too much than not enough.
A good thing to do if you're learning how to use the whole "autoconf" world
is to run a simple "./configure" with NO options.
Read the output, as it is fairly detailed, figure out what you feel is
missing that you need, and then add the options. It's a
repetitive/iterative process, but it's the best way to learn this, and
you'll find it much easier next time you have to compile something.
Normally, "configure" will detect the system's jpeg and png libraries
automagically anyways, so you don't really have to specify them on the
command line. I've never had the situation where it doesn't since I use
Linux, and pretty much all Linux distributions come with those libs
installed ... If it doesn't however, just to be safe, I'd install them.
Are there any developpers out there that could tell us why the JPEG and PNG
libraries are looked for outside of GD support ? (I'm thinking it might be a
historical leftover also ...)
Hope this helps,
J.F.

Subject: [Mapserver-users] Compiling Mapserver/configure options
Hi list,
I'm quite new to Linux and compiling software from source, so bare with me.
When it comes to compiling Mapserver I have some questions regarding the
./configure options.
There are some components with seem to be duplicated in different parts of
the compile process. For example I can compile jpeg support separately into
gd, gdal and mapserver.
Am I right in saying that if I compile jpeg into gdal I can have jpeg as an
input data source? If I compile jpeg into gd I can output jpeg images? If I
have compiled jpeg into gd I don't need to compile it into mapserver
directly with the --with-jpeg (as long as I use --with-gd) as it will use
gd's code to do jpeg manipulation? Similar with png?
Thanks,
Benjamin Wragg
