Zlib and Pelles C

[Freddy]

Hi Pelle!

I really like your IDE, compiler and tools.
After searching over the internet, I've found that Pelles C is the greatest IDE/compiler/linker for C development on win32. I think it's even better than MSVC++, because it's clean and light-weight.

I was thinking about creating a compression program. I've found zlib and I'll use it to create my file packer.
I need help installing zlib on Pelles C. I've downloaded zlib on http://www.zlib.net/ (zlib for Windows 9x/NT (DLL and static version). Installed it. Now I need help on what files I have to put on what folder.

Thanks!

I have put "zlib.lib" on "\PellesC\Lib" and "zlib.h" and "zconf.h" on "\PellesC\include\" and tried to compile this code:

Code: [Select]


#include <stdio.h>
#include <zlib.h>
#include <stdlib.h>


int main(int argc, char *argv[])
{
Bytef *data1="aaaaaatestauhuhauhauah";
uLongf size1=sizeof(data1);;
uLongf size2=size1;
Bytef *data2=malloc(size1);
compress(data2,&size2,data1,size1);
puts(data2);
getchar();
    return 1;
}



and returned these errors:

I don't have time to test at the moment, but you might try to check/uncheck "Enable Microsoft extensions" and recompile. If that doesn't work, look in zconf.h. It tries to auto-detect various compilers, but I'm not sure how well it works...
