SDK vs. own compilation

[codeman]

Hello friends,

until now I have compile my lib by my own. Have the sdk all modules compiled. what is the difference between the sdk and the own compilation.

My version now is 4.5.1 and I think to upgrade now, but get some errors in 4.5.2 in past and would take the ready to use sdk.

[codeman]

No suggestions???

Ok I install the new sdk with mingw I set all my env variables, clean my project
start qmake && make and I get an error.

It says me :

sources\tableeditor.cpp|36|headers\\ConDB.h: No such file or directory|

sources\tableeditor.cpp|36|headers\\ConDB.h: No such file or directory|

To copy to clipboard, switch view to plain text mode 

"headers\\ConDB.h"

That is very strange with 4.5.1(own compilation) it works. What is the problem here..

[codeman]

Ok here is the solution:

I have to change my lines from:

#include "folder\\some.h"

#include "folder\\some.h"

To copy to clipboard, switch view to plain text mode 

to

#include "..\\folder\\some.h"

#include "..\\folder\\some.h"

To copy to clipboard, switch view to plain text mode 

Could anybody explain me what is changed in the sdk.

[axeljaeger]

Why do you use \\ as a seperator char? usually you use / and never ever add things like .. in the include statements but include the directory .. in the include path for your compiler.

[codeman]

What would you suggest .
What should I enter in .pro file?

[axeljaeger]

INCLUDEPATH += <yourincludepath>

[codeman]

Ok I include the line

INCLUDEPATH += . headers sources

INCLUDEPATH += . headers sources

To copy to clipboard, switch view to plain text mode 

and then change the line
from

#include "..\\headers\\tableeditor.h"

#include "..\\headers\\tableeditor.h"

To copy to clipboard, switch view to plain text mode 

to

#include "/headers/tableeditor.h"

#include "/headers/tableeditor.h"

To copy to clipboard, switch view to plain text mode 

I get this error:

sources\main.cpp|10|/headers/tableeditor.h: No such file or directory|

sources\main.cpp|10|/headers/tableeditor.h: No such file or directory|

To copy to clipboard, switch view to plain text mode 

and now??? Do I misunterstood something wrong

[bender86]

If file tableeditor.h is inside a directory in the INCLUDEPATH you could do this way
#include <tableeditor.h>

[codeman]

First of all,thank you. Now, just for understanding.
How should my project file to be built. My looks like this at the moment

TEMPLATE = app
TARGET =
DESTDIR = bin/
DEPENDPATH += . headers sources
INCLUDEPATH += headers
 
CONFIG +=release
CONFIG += qt console
QT +=sql gui network core
 
# Input
HEADERS		+=	headers/file1.h 
SOURCES		+= 	sources/file1.cpp sources/main.cpp
 
RESOURCES 	+=	myproject.qrc
 
 
RC_FILE		+= resourcefiles/myproject.rc

TEMPLATE = app
TARGET =
DESTDIR = bin/
DEPENDPATH += . headers sources
INCLUDEPATH += headers

CONFIG +=release
CONFIG += qt console
QT +=sql gui network core

# Input
HEADERS		+=	headers/file1.h 
SOURCES		+= 	sources/file1.cpp sources/main.cpp

RESOURCES 	+=	myproject.qrc


RC_FILE		+= resourcefiles/myproject.rc

To copy to clipboard, switch view to plain text mode 

And how do I set INCLUDEPATH ???

[axeljaeger]

The pro-file looks fine for me. Now just change #include "headers/myheader.h" to #include "myheader.h" and you are done.

[codeman]

Ok with this constellations I get an error

sources\main.cpp|10|file1.h: No such file or directory|

sources\main.cpp|10|file1.h: No such file or directory|

To copy to clipboard, switch view to plain text mode 

[axeljaeger]

And the directory that contains file1.h is added to the includepath? Then we need the full command line to gcc to track down whether the includepath was added.

[codeman]

OK, I change my pro to to this one

TEMPLATE = app
TARGET =
DESTDIR = bin/
DEPENDPATH += . headers sources
INCLUDEPATH += absolute/path/to/my/headers
 
CONFIG +=release
CONFIG += qt console
QT +=sql gui network core
 
# Input
HEADERS     +=  headers/tableeditor.h 
SOURCES     +=  sources/tableeditor.cpp sources/main.cpp
 
RESOURCES   +=  myproject.qrc
 
 
RC_FILE     += resourcefiles/myproject.rc

TEMPLATE = app
TARGET =
DESTDIR = bin/
DEPENDPATH += . headers sources
INCLUDEPATH += absolute/path/to/my/headers
 
CONFIG +=release
CONFIG += qt console
QT +=sql gui network core
 
# Input
HEADERS     +=  headers/tableeditor.h 
SOURCES     +=  sources/tableeditor.cpp sources/main.cpp
 
RESOURCES   +=  myproject.qrc
 
 
RC_FILE     += resourcefiles/myproject.rc

To copy to clipboard, switch view to plain text mode 

and in my main.cpp I have this line

#include "tableeditor.h"

#include "tableeditor.h"

To copy to clipboard, switch view to plain text mode 

I get this error

sources\main.cpp|10|tableeditor.h: No such file or directory|

sources\main.cpp|10|tableeditor.h: No such file or directory|

To copy to clipboard, switch view to plain text mode 

I am beginning to despair!!!!

[axeljaeger]

Give me the commandline that the compiler gets, otherwise I cannot help you.

[squidge]

Since you are using Windows, you can use FileMon to see where that header file is being searched and modify appropriately. It's saved me a headache a few times in the past.

But the compiler command line should tell you exactly where it is searching for include directories. It's the most useful part.

[codeman]

ok. do you mean this

To copy to clipboard, switch view to plain text mode 

[axeljaeger]

Right, this is what I need. -I means add the following path to the includepath. Do you see your directory that contains the header there?

[codeman]

Ok I unserstand what do you mean. I don´t see the path to my headers right from the flag -I.
But as I before post it, my INCLUDEPATH variable looks to my path with my headers??

[axeljaeger]

Then obviously the step from .pro-file to makefile fails. How do you give your absolute path in the makefile? what exactly is path/to/files? Maybe you need to put in quotes, use forward slashes instead of backslashes or the other way around?

[codeman]

Thanks a lot, but it fails.

I use this

INCLUDEPATH += X:/CODEBLOCKS/cbprojects/VerteilungsRechner/headers

INCLUDEPATH += X:/CODEBLOCKS/cbprojects/VerteilungsRechner/headers

To copy to clipboard, switch view to plain text mode 

And I try it with double backslash, with quotes, with braces etc nothing helps....
