I'm not familiar with ex23.c but the errors appear to me to suggest that
you have a library in your link definitions that
contains the same object modules already defined in the AutoTester
project settings. In other words, the methods appearing in the errors
are already present in some part of the build step before the linker is
invoked. It could be that they are already included in the project
build settings AND you are linking in a library that also contains the
object modules for the same routines.
Examine your build settings to see if there is overlap. If so,
eliminate one source of them - either remove them from the project build
and include the library, or vice versa.
Hope this helps.

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:

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.

Is to remove the files GARealGenome.cpp and GAStringGenome.cpp from the
Solution (right click in Solution Explorer and Remove).
Thanks to Matthew Wall for the answer,
