Hello,
I’m having trouble getting zziplib to work and it’s probably something
stupid i’m not seeing.
I’m using zziplib-0.10.82 and zlib122 in MSVC6 and the linker says:
Code.obj : error LNK2001: unresolved external symbol _SDL_RWFromZZIP
Release/Build.exe : fatal error LNK1120: 1 unresolved externals
The following includes are in the source:
#include “zzip/zzip.h”
#include “SDL.h”
#include “SDL_rwops_zzip.h”
Linked (both in lib folder):
zdll.lib
zziplib.lib
Project folder:
SDL_rwops_zzip.c
SDL_rwops_zzip.h
Include folder:
zzip/__debug.h
zzip/__dirent.h
zzip/__hints.h
zzip/__mmap.h
zzip/_config.h
zzip/_msvc.h
zzip/conf.h
zzip/file.h
zzip/format.h
zzip/lib.h
zzip/plugin.h
zzip/stdint.h
zzip/zzip.h
zlib.h
zconf.h
Did i forget includes or links here? cant figure it out… thanks.

PS: ive searched the mailinglist, google and my below average knowledge of
C++, but couldnt find a solution.
Hi there.
“unresolved external symbol” means that the linker
did not found the code for “_SDL_RWFromZZIP”.
It happens when you include the declaration of a
function (so the compiler says “it is ok, this
function exists, maybe it is declared in some other
source file”), but the linker did not find it in the
object files that it is linking.
Make sure the lib that contain the code for
"_SDL_RWFromZZIP" is included in the libs of your
project (or solution).
Hope I had helped,
In?cio.

Thanks for your reply.
The docs with SDL_RWFromZZIP state:
“Just copy the two files SDL_rwops_zzip.h and SDL_rwops_zzip.c to the
directory with your other project sources, and make sure to link it somehow

I’ve copied the two files to my project folder and added a #include
"SDL_rwops_zzip.h" at the top of my source, apparently this isnt enough.
How do I link these files to my project?

I don’t know if you’re using a development environment, but it sounds
like you’re not including the C file in your actual project. This is
easy to rectify for VC++ or Dev-C++ or any other such editor, simply
add the file and recompile.

Hi there.
Have you added the .c file to your project? (Some
IDEs just compile what is on the project, wich is a
script containing the list of files to compile).
Give a look at the docs of the IDE you are using and
see if it works like that.
Hope I Helped,
In?cio.

Maybe you should add both .h and .c to your project, not
just copy them into project folder. If you use VS, this can be
done by r-clicking on "source files" and "header files" icons in
solution explorer window, then selecting "Add->Add Existing Item"
menu item.--
Best regards,

Did you include the SDL_rwops_zzip.c in the project source list (or

should you include the .c file?
i don’t think so.
the errors you are getting sound as if the file was written to be part
of the library.
if so, then it will be part of the SDL library, you just need to
include the header.
i’m no expert on dlls or anything so feel free to contradict me.
brian
no the .c file should be included, the code inthere isnt part of any lib but
makes use of functions in the zzip lib.
if the function were part of the library, it wouldv been simple :}
