No, there is not.

OK, thanks for the correction.  Apologies to those on the Lazarus team, 
it's a substantial body of work and quite an achievement.

Have you looked at FPC FAQ (in particular,
https://www.freepascal.org/faq.var#systemnotfound), or FPC documentation
(https://www.freepascal.org/docs-html/user/usersu7.html#x21-280003.1.2)?

FPC Wiki is an additional resource, there is some information related to
Lazarus as well - see
http://wiki.freepascal.org/Unit_not_found_-_How_to_find_units.

All of this might help you in finding differences; note that installation
packages created for specific Linux distributions may decide to modify the
default unit locations.

Hope this helps

Tomas

There is my old feature request about it

Most developers are using single .inc file that contains all
directives for the whole project.
You only need to remember to include this file in all units of your projects.

[fpc-pascal] TBufDataset vs TClientDataset

2017-10-08 Thread Graeme Geldenhuys 

Hi,

I read a couple of archived mailing list posts about TBufDataset, which 
from what I read is FPC's equivalent to TClientDataset.


That then begs the question... Why isn't it called TClientDataset in 
FPC? What happened to Delphi-compatibility?


Also, what's the difference between TBufDataset and TMemDataset? Aren't 
they both in-memory datasets? If so, why do we have two different 
components for the same thing?



Regards,
  Graeme

No one seems to care to implement it, so if you badly need it:  sj.patch
  
Apply in compiler directory (please checkout r37430 at least), I only svn
diff there, not in the top level directory (I have modifications to certain
packages).

Good question...

Yes, they are both in-memory datasets and, I believe, TMemDataSet came
first and TBufDataSet could be an improvement. Here ->
http://wiki.freepascal.org/How_to_write_in-memory_database_applications_in_Lazarus/FPC
says that TBufDataSet is a better choice.

Why two classes for the same thing? I have no idea.
