Dear everyone,

this looks like a noob issue...
I've created something simple in U++, using TheIDE and MinGW as a compiler. As long as I use the String type in the project's main translation unit, I'm fine.
At some point down the road, I've moved some of my code into a new .cpp file and a new .h file in the same project and directory. Trying to create a separate translation unit - a local library if you will. If I #include <String>, I'm getting "error: 'String' does not name a type" . I've tried putting "using namespace Upp;" on top of the file, I've tried qualifying the String in variable declarations as Upp::String... none of that helps (the compiler even says that the Upp namespace doesn't exist). I'm not very fluent in the namespaces and this is probably something pretty simple... Any help would be welcome.

Actually I've just found out that if I #include <Core/String.h>, I get rid of the "String undeclared" error message, but instead I get a waterfall of complaints about WChar, 'byte' and 'force_inline' etc. not being declared (messages coming from String.h). I'm puzzled... Is there some upper-level header file that I should #include in the first place?

Okay, so I assume the sweet secret is:

#include <CtrlLib/CtrlLib.h>
using namespace Upp;


at the top of my own .H file...

Hi Frank

Do not worry. Even after some years working with U++, sometimes I forget some .h.
Lots of times I do not begin with empty files, but from previous files.

Anyway, comparing with other environments, in my opinion, U++ is simple and nice with the programmer.


Best regards
IƱaki

@koldo: thanks for your warm, reassuring response Smile I'm a noob, I need to find my way around and about. Overall U++ feels stable and to the point, I like it. I cannot say I have enough time to play with it, but as this is a hobby project, there are no deadlines to rush me and haunt me.
