Need help linking with zlib.

[kiseitai2]

Hi everyone. I'm a noob to c++ (I only know basics such as interpreting the code and syntax rules, but I haven't done a major successful program yet.). I'm having trouble in the link phase. The function compress2 compiles fine but then I get the linker error undifined reference to compress2, which is declared in the header zlib.h inside my include folder. I'm using Dev-Cpp, the zlib 1.2.2 dev-pack, and the mingw32 compiler set.

Any suggestions are welcomed! Thank you,

Have you linked to zlib? You compiled zlib, right? From which you should have the dll and the lib to link with. Specify that lib in the linker options.

How dumb of me!!! Thanks man! It's a shame I usually get helped and I have only being able to lend a hand once or twice other people. :(

The following steps requires:
1) The installation of the zlib dev-pack.

For those of you with Dev-Cpp (like me) go to the project options >> Parameter,
then below the linker textbox look for the button Add Library or Object. Then, click on it and go to the folder Dev-Cpp\ lib and select libz.a. Afterwards, type #include <zlib.h> in the source file (cpp or h) and compile and use any functions. (No need to have the dll. I guess, it is because it is the static library compilation of the zlib source files)

Have fun!!!!
