backend-file loading check; reasons for gncla-dir.h? (was: Changelog - (end))

[Christian Stimming]

Dear Neil,

thanks for committing a solution to this problem.

As it is not yet clear whether this fixes all potential setups, can you 
please additionally insert a check into the gnucash code that will check 
for the correct loading of the gnc-backend-file library? In the current 
gnucash, the whole program will fail if that backend-file hasn't been 
loaded. So can you please make a check for this a fatal assertion for 
now? That will make the source of the problem much more obvious than the 
weird "namespace error" messages.

For the record, I don't use opt-style-install, too, because I try to use 
as much of the default settings as possible. (Although the experimental 
branches will be installed in separate --prefixes anyway.) So that 
potential end-user (installation) problems will already show up during 
development.

And nevertheless I still don't fundamentally understand the need for 
passing directory names by C header files. I would still think we were 
better off if none such mechanism would be needed.

Not to mention the fact that this is surely not at all part of the 
changes that are "essential" for the initial gnucash-2.0.0 release. 
Ceterum Censeo [1] this and similar fundamental changes in src/engine/ 
which are non-essential for gnome2 should be done on a separate branch, 
*not* on the branch that is intended to reach a gnome2-release as soon 
as possible.
