[galib] Multiple definitions in MS Visual Studio 2003, V7.1.3088

[Mike Cooling]

Hi

 

I'm trying to compile an exercise (ex23.c) from Galib in MS Visual Studio
2003, V7.1.3088, on a Windows XP machine.

 

I've tried Kevin Druhan's solution, including changing the #includes to read
*.hpp *.cpp. I can get a very simple example to run fine this way.

 

However, with ex23.c I errors thus:

 

AutoTester error LNK2005: "int __cdecl GARealArithmeticCrossover(class
GAGenome const &,class GAGenome const &,class GAGenome *,class GAGenome *)"

td@@@std@@@Z) already defined in AutoTester.obj

AutoTester fatal error LNK1169: one or more multiply defined symbols found

 

I have also tried leaving the .c files as .c files, setting the Project and
File options to /TP, and including the folder that contains the ./ga folder
in the Projects VC++ Directories (so I don't have to change

<ga/whatever.c> to "whatever.cpp". In this case I still get the above
errors.

 

What am I missing? If there is anyone out there using MS Vis Studio and can
help please let me know.

 

Thanks for your time,
