Generate a correct makefile

[SteM]

Hi all,
my problem is t write a correct qmake.conf file to avoid to point to /usr/lib and /usr/include files cause otherwise the crosscompilation mixes some files..

Which directive i need to overwrite/define to point only cross libs and includes ?

Thanks

[high_flyer]

cause otherwise the crosscompilation mixes some files

Could you explain what do you mean by that?
The reason I ask is, that the qmake.conf has the qt configuration on your system.
So if you want to cross compile on the same system for other arhchs, then the files for those other archs will *HAVE* to be located in other locations as the ones for the current system.
So how could they be mixed up?
For example:
if you have on your current system:
#include <somesysheader.h>

then the header for the other archs will have to be somewhere else.
So in your code you will have to:
#include <otherarch/somesysheader.h>

Usually an #ifdef clauses are used to select the correct includes.

I'm sorry, my message was not so clear ....
I created a custom mkspec/linux-somethig/* files.
When i run qmake command and i take a look to the generated Makefile, i always see the inclusion of /usr/include/ and /usr/lib/ paths, even if i didn't write them into the .conf file !

How can i overwrite o modify this setting ?
I do not inculde any other conf file ..

Thanks

[high_flyer]

how did you call qmake do use your custom conf file?
Any way, have a look at QMAKESPEC.

[wysota]

/usr/lib and /usr/include is a standard (hardcoded?) path to look for libs/headers in your system/compiler, so it might be hard getting rid of it. You can try doing it by not including any of the standard files, but to do that, your specs can't be called linux-something but falafel-something (to make sure linux files won't be included).

[Brandybuck]

/usr/lib and /usr/include are the standard location for libc. This is vitally necessary for any C/C++ application, including Qt applications.

[SteM]

Thanks for your attentions.

Sorry, a step backward ...

When i cross-compile QT for my toolchain i created a new qmake.conf to notify the path and the name of the cross compiler and then i included linux.conf file.
I saw on console that the compiler is the wanted one but in the compiler command line there are some references to /usr/local/Trolltech/Qt-4.2.2/ path: for example:
-I/usr/local/Trolltech/Qt-4.2.2/include/QtCore -I/usr/local/Trolltech/Qt-4.2.2/include/QtCore -I/usr/local/Trolltech/Qt-4.2.2/include/QtNetwork
which are the files compiled for the host machine !

My questions are:
- is the reference correct for the crosscompilation?
- or do i need to point out the original qt sources installation path (on /tmp/qt-commercial-xxxxx/)?
In the case, do i need to change the variables:
QMAKE_INCDIR_QT = $$[QT_INSTALL_HEADERS]
QMAKE_LIBDIR_QT = $$[QT_INSTALL_LIBS]
???

Thansk again.

Thanks!

[high_flyer]

did you try what theLSB suggested in his last post?

QMAKESPEC

This variable contains the name of the qmake configuration to use when generating Makefiles. The value of this variable is typically handled by qmake and rarely needs to be modified. Use the QMAKESPEC environment variable instead.

[SteM]

For the application i simply used:
qmake -spec linux-montavista

Compiling QT i used the following:
./configure -qt-gif -no-rpath -plugin-sql-ibase -platform linux-montavista -prefix /root/workspace/qt -I/opt/firebird/include -L/tmp2/qt_compil

I inserted the Qt package on my virtual machine based on the MontaVista Linux, just to avoid to handle a cross compile.
If I run the command:

./configure -qt-gif -no-rpath

Crosscompilation or not i'm not able to build QT libraries !!

[high_flyer]

It seems you have a commercial license.
Did you contact the TT help desk?

[SteM]

I do not have the direct contact with the TT help desk, i will try to contact Technical Manager of my company in US ...

Then i return to crosscompilation issues:
what about the reported problems ?? :-(
Does my qmake.conf seem to be correct ?

[wysota]

qmake.conf is only a part of configuration files used by qmake, so it's really hard to say.
