thousands of system/library/frameworks errors of declaration for parameters... (MAC)

[rickrvo]

Hi,

I'm trying to port a Linux application to Mac using Qt. The same code runs perfectly on linux but on Mac I get thousands (~22700) of errors like:

as well as some " i686-apple-darwin10-g++-4.2.1: -zmuldefs: linker input file unused because linking not done " errors


Do I need to add some kind of configuration to the project.pro file in order to get rid of these framework errors?

[llev]

Headers shown in those error messages are Objective-C. They can be included from Obj-C code only. For instance, from .m or .mm sources.
Does your app include some mac-specific header directly?

[rickrvo]

Hi llev,

Sorry but I don't understand your question... I have no .m or .mm files in my project too...

This app that I'm working on has a set of different configurations (like #if defined(Q_OS_LINUX) ) for windows and linux. I copied the config from linux to be used for mac

[llev]

1. The error messages you showed are from compiling stage (not from linking), correct?
2. If they're, some source in your app includes mac-specific header, doesn't it?
3. You could find that #include and decide whether you need it.
For instance, NSGraphics.h header is written in Objective-C++ programming language as well as most Cocoa API headers.
Objective-C++ sources are not compatible with C/C++ sources.
That's what I tried to say in my previous post.
Am I clear?

[rickrvo]

I think I got it now.. lol

1 - yes they are from compiling stage

2;3 - I don't know... I don't think that it does... can you show me an example of a mac-specific header? All I know is that the app is working on windows and linux, and I used the same configuration for linux to try to build in mac.

I think that some configuration is missing in the .pro file or, like you said, something is conflicting with the cocoa API headers.

but for it to be returning 22k errors probably has something to do with the incompatibility...

How do I search for these mac headers?

[llev]

For instance, Obj-C headers use #import directive instead of #include one.
Hearders which name starts with NS are likely Obj-C.
Could you paste here a piece of build log with command line invoking compiler on some source and subsequent error messages?

[rickrvo]

this is the line right before it starts going mad...

oh and there are no "#import" on my projects

[llev]

It seems x11/x11vnc/macosxCG.c includes mac-specific Obj-C headers at least.
And, as per log, x11/x11vnc/macosxCG.c is included in another .c file. It's strange a little :)
Here's an example:


In file included from /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:6,
from /System/Library/Frameworks/Foundation.framework/Headers/NSArray.h:5,
from /System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:10,

from x11/x11vnc.c:42:
/System/Library/Frameworks/Foundation.framework/Headers/NSZone.h:8: error: stray '@' in program


I would say x11/x11vnc/macosxCG.c includes <Cocoa.h> at line 14.
Are you familiar with x11/x11vnc/macosxCG.c source?

[rickrvo]

hum not really... but probably the app needs it ( since it is a vnc controlling application )

that file is from another set of opensource project files that does the vnc communication, I think...

[llev]

Well.. I'm not familiar with vnc port. Not sure.
You could check contents of x11/x11vnc/macosxCG.c as well as x11/x11vnc.c to determine whether the port supports Carbon API.
Actually Mac provides two major APIs: Carbon and Cocoa.
Cocoa is modern object-oriented API written mostly in Objective-C++
Carbon is older API written in plain C.
Usually ports support both API and selection is done by defining some macro (something like USE_COCOA) or by customizing .pro file.
Try to search those two .c files for COCOA or CARBON words in #ifdefs.
Maybe .pro file of the port should be customized.
Or maybe configuration script of the port can accept some command-line parameter which turns Carbon support on.
Wish you luck :)

[rickrvo]

thanks! I'll try to take it from here. I'll post here if/when I discover the problem :)
