Thank you gentlemen for all your help.

I have downloaded the latest zlib 1.3.1 and am getting a bit further.
Now I only get this error:
Building pdfiodll.dll. but POLINK cannot find 'zlib.lib'?

I have to wait a bit as I don't really know what I'm doing. "Just trial and error"

As you have a compilable project, you can try to compile it and check compiler options.
Just inform us of problems with it.
It have strange include file problems, like zlib.h, not sure, if it can be a bug.

What is POSIX and when is it used?

https://en.wikipedia.org/wiki/POSIX


AI Overview

Pelles C is primarily a Windows-focused C compiler and development kit that offers some limited or partial support for POSIX-style functions, but it is not fully POSIX-compliant.

Key points regarding POSIX and Pelles C:

    Windows Focus: Pelles C is designed for native Windows API programming. Windows APIs are not part of the POSIX standard, which defines a standard operating system interface for Unix-like systems.

    Partial POSIX Support: Pelles C has added support for some "Posix-style functions" over the years, such as the three-argument version of a function like open(). However, this support is incomplete.

    Missing Features: Users on Pelles C forums often note that key POSIX headers or functions are missing or commented out, such as unistd.h's sleep() function or important members of the
    struct dirent used for directory operations.

    make Utility: The Pelles C pomake.exe utility is noted as being "even less POSIX-complete" than the Microsoft nmake.exe, which itself is not fully POSIX-compliant.

Many thanks for your help,
Unfortunately I haven't gotten it to work despite your suggestions and your file? However, I feel that I have come a little further. Think I've localized a problem in my zlib.h?
Don't know if it's my version or how I placed it but I'll continue.

I keep going and it's a lot of trial and error.

In summary, it feels like pragmas for different settings are something you need to learn.

I guess Christian, our forum administrator can attach Pelles C v13 to the Downloads section.

It would be excellent if Mr Pelle himself manage a section of this forum with the releases.
That would finally clarify that PEllesC is live and developing.

New year new opportunities!

Found PDF-lib in https://www.msweet.org/pdfio/

Want to be able to read text from a PDF. Have tried lots of settings and options without success. It says it should work with C99? But what is POSIX-compliant?

Can someone give me a push in the right direction to move forward on how and try to get it working.

Thanks in advance

Hello,

Did you visit the Downloads section of the forum?

https://forum.pellesc.de/index.php?board=26.0

Yes, but don't you think that a link to wayback machine for the last release is alarming? 
Would be so unacceptable to host PellesC Releases on this board?
