Undefined reference to EVERYTHING
-
My problem is pretty simple: [url=http://www.yaharr.com/i/qt_1331errors.png]Everything is an undefined reference (CLICK FOR SCREENSHOT)[/url].
This project was not made by me. It compiles just fine on it's author's computer with Qt Creator (on Windows 7).
When I open the CMakeLists.txt with Qt (File > Open File or Project...) and Build All (Build > Build All), however, I get over a thousand errors due to everything being an undefined reference.
- I'm using Windows 7 Professional 64-bit
- I'm using MinGW 4.4 to compile - the same MinGW 4.4 that comes with Qt Creator's installer.
- I have CMake 2.8
- My packages are here: [url=http://www.yaharr.com/i/qt_packages2.png]Screenshot[/url] (updated)
- Here's the part of my PATH variable that isn't just basic system stuff:
... C:\Program Files\Java\jre6\bin;C:\Program Files\TortoiseSVN\bin;C:\Program Files (x86)\CMake 2.8\bin;C:\Program Files (x86)\QuickTime\QTSystem;C:\Dynamic\QtSDK\mingw\bin;C:\Dynamic\QtSDK\Desktop\Qt\4.7.4\msvc2008\bin;C:\Dynamic\QtSDK\Desktop\Qt\4.7.4\mingw\bin
To reiterate, this project compiles just fine on another Windows 7 PC.

-How would I obtain that information?-
EDIT: Our makefile (CMakeLists.txt) contains this:

Is that the information you're after?

[quote author="Lukas Geyer" date="1321879284"]The acutal call to the linker would be interesting, especially which pathes and libraries get passed.[/quote]
How do I acquire that call information?This is my first time dealing with makefiles, and my usage of C++ compilers (apart from Visual Studio's) has just involved single-document scripts.
