Compiling projects

[giesbert]

it's not the "QT += xml" if the linker does not find the libs.
can you please post your pro file content?

[giesbert]

Hi alexspin,

Why do you run configure.exe if you don't build qt? It overwrites some files that are used by qmake...
Also, I think the sdk brings a mingw by itself, right?

Here the pro file:

Your steps 2 and 3 (installing mingw and running configure) are likely the cause of your problems. The SDK installer sets it all up for you, ready to use. I would re-install the SKD; that would be quicker than trying to fix the issue manually I think.

[alexspin]

Thanks Andre and Gerolf. I try to unistall and reinstall the SDK and test.

[giesbert]

as you use ui stuff, you should have this in the beginning:

@
QT += core gui xml
@

[andre]

By default, QT already has at least core (and I believe gui too). So just

@
QT += xml
@

should be enough.

IMO, this sounds like the path doesn't contain the route to the libraries, so they aren't being found. If this is the case, maybe using -Lfulllibroute instead of -llibname could be useful (-L full lib route, -l library name). Also, I don't know which $PATH(s) mingw's ld looks into...

I've uninstall Qt sdk and minigw and reinstall only Qt sdk.
I've load my project, run qmake and build project obtaining a lot of error like:

_undefined reference to __gxx_personality_sj0'_ _undefined reference to Unwind_SjLj_Register'
_undefined reference to _Unwind_SjLj_Unregister'_ _undefined reference to Unwind_SjLj_Resume'

It seems like a non correct library link.

[Guest]

After such a tremendous software removal and reinstallation... a full clean build is recommended, IMHO.

[alexspin]

I've done it but I obtained the same errors.

[alexspin]

I have reinstalled the Qt SDK and after compile my project I obtained this errors:

./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0xb7): undefined reference to `__gxx_personality_sj0'

./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0xca): undefined reference to `_Unwind_SjLj_Register'

./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0x113): undefined reference to `_Unwind_SjLj_Unregister'

./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0xa76): undefined reference to `_Unwind_SjLj_Resume'

for each file.

How can manage this? Which library contain that reference?

Please help!

[alexspin]

Ok, I've done it.
I've installed the SDK that the project was made, 2009.03, and with this the project compile correctly.

Why?
Any ideas?

2 years ago... too many changes in Qt since that moment in time? Couldn't say, as i recently joined this page...
