[gdal-dev] Standard Dev. Environment?

[Even Rouault]

Jay,

hum it is well possible that the build with --without-jpeg doesn't work and that
some drivers will try to use it. I haven't tried it for ages. GDAL has an
internal version of libjpeg, so when you've no external libjpeg, that one will
be picked up. I imagine that very few people test --without-jpeg.

Frank suggested you to just use plain "./configure". I'd recommend strongly that
you just to try it. This must work well and autodetect which libs are available
or not. The BuildingOnUnixWithMinimizedDrivers page you quote represents a
non-standard configuration of GDAL, so you may hit rough corners.

To answer your question concerning the value for --with-jpeg, it is the
installation prefix of libjpeg. Typically /usr for system jpeg (but that one
would be picked up implicitely) or /usr/local (if you've installed your own
libjpeg).
