Undefined symbols for architecture i386 [solved]

[Hedge]

I did it and keep getting the same error while doing make.
styleitem is a nested project.
Do I have to add the macx:CONFIG += x86 line to the overlaying projects perhaps.

It shouldn't harm. I had no problems compiling the plugins for my Qt libs. So this seems to be some weird combo of issues.

Can you give some more details on your environment:

• Qt version?
• SDK or prebuilt binary framework or manually compiled libs?
• Carbon or Cocoa?
• output of "qmake -query"
• output of "file /path/to/your/qt/libs-or-framworks/QtCore.framework/Versions/Current/QtCore (it shows you the architectures Qt is built for)
• output of the compiler run (calling make), at least a snippet, to analyze the actual compiler calls

[Hedge]

Qt version 4.7.3, manually compiled (there are no precompiled libs for Mac 32).

I don't know how to determine whether Carbon or Cocoa is used.

Output of qmake -query

Now I've got the same shit with a 64 bit Mac but with the error-message:

@symbol(s) not found for architecture x86_64@

This is the compile output:

@Undefined symbols for architecture x86_64:
"StylePlugin::registerTypes(char const*)", referenced from:
vtable for StylePluginin moc_qstyleplugin.o

ld: symbol(s) not found for architecture x86_64@

I added macx:CONFIG += x86_64 to the pro-file but that didn't change anything.

EDIT: I finally found the reason why building the desktop components failed. For some reason two files of the desktop components were changed (I found out via a simple git status). Now it compiles fine on both Macs.

Ah! Good to know. Could be I cloned the already corrected version from gitorious. Usually Mac environments are not that different :-)

Good luck with your further development!

I have the same problem, the version of my Mac is 10.7, and when I compile the same message appears, have tried everything. Do you know any solution?!

Tks,

Tokunaga.

[Guest]

I decided that....

[goetz]

If you already tried everything, chances are bad that there are a solution. If you didn't..... it would be helpful if you told us what you've done.

Why Wolker??? Do u have a problem???

Me? No. I think it's you having a problem. At least that's what you stated previously:

[quote author="Tokunaga" date="1319961219"]I have the same problem[/quote]

But it's hard to know what you did decide, though:

Can you elaborate a bit more precisely?

[Guest]

Volker

somebody could solve this?
well, if you use a qt 4.7.4 on a Mac 32-bit it really appears, I checked other tutorials and talk to compile gcc libraries.
You know what really needs to be done? anyone have any solution?

[Guest]

Do you have msn or something??
