Got an error when compiling our code:
In Windows 7 and visual studio, I at first did not notice the problem, but it was giving a warning:
LNK4042: object specified more than once; extras ignored
In Linux and gcc it gave an error, so I could not compile the code:
multiple definition of `<constructor of class>'
collect2: ld returned 1 exit status
I took som time to figure it out, but turned out to be a bad merge in subversion,
the *.pro file had the same class twice in
HEADERS += \ Class1.h /
SOURCES += \ Class1.cpp /
Rremoving the second time the class name where entered in the *.pro file solved the problem.
