problem with linking

[mickey]

thanks; I have some # at the begon of mainform.ui.h file; other are in implementation from designer (they aren't the same!). is this ok?
THen I subclassed mainform to myMainform: now in mymainform.cpp file I find same include that are in mainform.ui.h; can I avoid this? and how? can this a problem?thanks...

[mickey]

only possible recursive incude is "mywidget.h" put in mainform.ccp from compiler, and a ponter to mainForm* w, member of mywidget class (inside mywidget.h, but I need it there!!). anyway I use

#ifndef MYWIDGET_H
#define MYWIDGET_H
.......................
#endif

#ifndef MYWIDGET_H
#define MYWIDGET_H
.......................
#endif

To copy to clipboard, switch view to plain text mode 

in mywidget.h. Can it be? can I avoid?

Can it be? can I avoid?

First of all try to use precompiled headers and see how much it helps (it will help much, but if it help too much it means that you may have some include cycles or something like that).

[mickey]

sorry for question, but what are the precompiled headers? I think you're refer an .net option but wich? I choose generate automatically and don't change nothing in compiling..; others get errors...

[mickey]

I don't know if can useful to solve problem but after generation code......(where sometimes goes slow) after appear this:

Read the article in our wiki.

ok I get out some include from mainform.ui.h; I change .pro and I inserte also stable.h line in include file (in the .pro I mean. right this??). I put #include "stable.h" in mainform.ui.h file
Is it all right? for the moment compilation time is the same...

Hmm... The article clearly mentions not to use stable.h as a regular include file, so it's not alright. Did you run qmake after modyfing the project file? And do you meet the requirements for using precompiled headers? Is your compiler supported?

[gfunk]

Incidentally, what are the specs on your machine? How fast is it? How much memory does it have?

[mickey]

500mb, centrino1700;
when I type nmake it's stopping for 49 seconds; after compiling re-start;
I DON'T know if my steps for header precompilated are ok (see before)..i putted about 50 include inside stable.h; don't change anythings.......

Before:

CONFIG	+= qt opengl console

CONFIG	+= qt opengl console

To copy to clipboard, switch view to plain text mode 

an now:

CONFIG	+= qt opengl console debug

CONFIG	+= qt opengl console debug

To copy to clipboard, switch view to plain text mode 

now it dosn't stop in compiling..
Do anyone get me any information? Probabily I don't know........THANKS

[mickey]

in effect after I take out stable.h from header lines in .pro but it seems work in the same way yes I typed qmale and nothing requirement.......I use .net 2003

Before:

CONFIG	+= qt opengl console

CONFIG	+= qt opengl console

To copy to clipboard, switch view to plain text mode 

an now:

CONFIG	+= qt opengl console debug

CONFIG	+= qt opengl console debug

To copy to clipboard, switch view to plain text mode 

now it dosn't stop in compiling..
Do anyone get me any information? Probabily I don't know........THANKS

But why this above? I notice, when I import project in .net and then type compile option (only compile not build) an apper a "non specificated error" what's it?? why with debug line in .pro dosn't stop but I have this problem in .net? thanks

[wysota]

Did you actually add the CONFIG += precompile_header statement in the project file? Could you compile your project manually using nmake and paste every line of output which doesn't contain the actual compiler command? Remember to run nmake clean before you run nmake.

[mickey]

I sent to you!

[wysota]

What about the project file? Because the output you sent doesn't even mention a try to precompile headers.
