Yes, I've read this file.

So, only developers, testers, contributors and involved users will
have access to particular provider project.

Though, personally I checkout FDO projects to my own structure a bit
different but it's not a problem as you explained in one of previous

Here I'd like to ask additional question.
As I understand, building any of the fdo[ProviderName] projects require
to have complete source tree of the fdocore.
And if I have built fdocore separately and I have fdocore
libs and headers installed it's still not enough to build provider,
the whole fdocore tree is required.
And those variables listed above should point to locations in the
Am I right?
Is there a plan to change it? To enable builing providers with fdocore

As I prefer running ./configure manually with custom options, I
extracted those calls to separate sctipt called autogen.sh :-)

Good to know.

I tried to run the UnitTest but it failed.
Here is the last message:
Test name: 7XmlTest.testXsl
Run: 99 Failure total: 1 Failures: 1 Errors: 0
Note, the strange characters above, something like binary output.
Do I need to do any configuration for the UnitTest?

What about environment configuration?
Anything should be set?

Does it mean I should not use custom installation prefix?
Also, is this required to install providers under the same prefix as

Yes, those test are failing now but first we are cleaning fdogdal
project and running other non-unit tests.
UnitTest will be fixed soon.

Thank you for such a great story about FDO.
I'm sure those posts will very helpful and must-read for new FDO
I asked my questions inline. If I have new questions, I'll ask in new posts.
Last questions I have are about directories naming convention used in SVN.
As I see, in the old fdo sources tree are use lower-case names.
In the new fdocore tree all directories are named with first letter
upper case. Is this intentional convention?
On Windows, names case does not matter but on Unix some unification
would be helpful.
In example, if on Windows someone on write
but the path is Fdo/Raster/MyFile.h
then it won't compile on case sensitive systems.
So, please tell me what is the dirs naming standard to follow.
