Undefined reference to my signal

[tomek]

Hi!
This is my first post so I'd like to say hello everyone!
I am trying to compile my simple project, but I get an error:

release\fetchThread.o(.text+0x387):fetchThread.cpp: undefined reference to `FetchThread::log(QString)'
release\fetchThread.o(.text+0x3ba):fetchThread.cpp: undefined reference to `FetchThread::connected()'
collect2: ld returned 1 exit status
mingw32-make[1]: *** [release\project.exe] Error 1

release\fetchThread.o(.text+0x387):fetchThread.cpp: undefined reference to `FetchThread::log(QString)'
release\fetchThread.o(.text+0x3ba):fetchThread.cpp: undefined reference to `FetchThread::connected()'
collect2: ld returned 1 exit status
mingw32-make[1]: *** [release\project.exe] Error 1

To copy to clipboard, switch view to plain text mode 

FetchThread::log(QString) and FetchThread::connected(void) are my own signals defined in the appropriate header file.
Files:
PROJECT DIRECTORY
WRONG CPP
WRONG H
It complains about my signals emitted from the above CPP file.
Please help
Regards,
Tomek
