I can't see why???

And now you are overlooking another BIG advantage of lazarus packages (which Delphi IDE suffers badly from and what you are trying to duplicate in Lazarus). If you have many projects relying on various components and you use unit paths instead of packages, you are going to have hordes of duplicate compiled units for the same component. The same .dcu files will littered all over your projects unit output directory, causing inconsistent versions of .dcu files and eating up lots of hard drive space. Using packages, you only have one set of compiled units, no matter how many projects use those lazarus packages. > But still, it can be very annoying.

No you don't have to! Have you heard of "project templates" or "new project add-ons". For example. If I want to create a fpGUI application, I go 'File > New .. > Project > fpGUI Application" and I'm done. Package dependencies are all setup for me already. I have the same thing for tiOPF project (and I often have loads of small tiOPF based applications). You simply create one Lazarus add-on package that registers a new project type and you are done. I believe Lazarus IDE includes an example of such an add-on. If not, I can email you such a package or a URL where you can find the code for such a add-on. I think the "project templates" feature in the IDE can also define package dependencies - Mattias or Michael might be able to confirm this. > My point view: the less IDE buttons need to be pushed - the better :) Agreed, developers are lazy by nature. :-) Hence the reason I use packages. You have to go "file > new" and then copy and past paths for each project. I simply go "File > New" ;-) I think I should really write an article or extended documentation on Lazarus Packages. Clearly many developers don't know what it entails and how flexible it can be. And it's a vast improvement over Delphi Packages!!
