Problem with theora on cygwin

[hogren]

I have copied /usr/local/lib/*.a and /usr/local/lib/*.la in /usr/lib .

My command :

g++ main.cpp -o prog.exe -logg -ltheora -ltheoraenc -ltheoradec

My result :

Thanks for help.

It looks like the library that you want to use has other dependencies. Try searching Google for the specific function names or error messages to find out what library you need to add.

Thanks for all.

The last problem is the compatibility between gcc 4 and libSDL in cygwin.
I must go to 3.x.

Thanks again !
