This document describes the requirements for using PDFlib GmbH binaries on
various platforms. This list covers all platforms on which at least one
product is supported. It should not be construed as a commitment regarding
the availability of a certain product/platform combination.

To find out whether a PDFlib GmbH product is supported on a particular
platform please check the downloadable binary packages at www.pdflib.com. 


================================
Java on all platforms
================================
Java 8 or above is required for the Java binding.


================================
Windows
================================

Requirements:
Windows 10/11 on x86 or x64
Windows Server 2012 and above on x86 or x64

C and C++ bindings
------------------
The delivered binaries (libraries) can be used to build applications with
Visual Studio and compatible products.

Project files for the programming samples are available for Visual Studio 2015.
Newer versions of Visual Studio convert these automatically.


================================
.NET
================================
The .NET binding is implemented as C# assembly using C# Interop with
additional unmanaged code in a native shared library. It is distributed as
universal package with support for the following environments:

- Windows x86, Windows x64, Linux x64, macOS x64 and arm64, Alpine Linux x64
- .NET Standard 2.0, e.g. .NET 8/9/10
- .NET Framework 4.6.1 and above
  (Visual Studio 2017 Version 15.7 or above)

The examples are written for Target Framework net8.0 In order to deploy
them with other Target Frameworks you may need to adjust the project files.


================================
Linux x64
================================
Requirements: GLIBC 2.12 or above and libstdc++.so.6.0.21 or above
based system on x64

C and C++ bindings
------------------

binutils: 2.26 or above
CFLAGS=-pthread
LDFLAGS=-pthread


================================
Linux ARM64
================================
Requirements: GLIBC 2.27 or above based system on ARM64

C and C++ bindings
------------------
Compiler: g++ 5 or above
CFLAGS=-pthread
LDFLAGS=-pthread


================================
Alpine Linux
================================
Requirements: Alpine Linux 3.4 and above on x64
musl C library (instead of glibc)

=================================
Requirements: FreeBSD 12/13/14 on x64


================================
AIX
================================
Requirements: AIX 7.2 and above

C and C++ bindings
------------------
Compiler: xlclang/xlclang++ 16.1 and above


Other language bindings
-----------------------
A C++ runtime implementation with support for C++11 and C++14 is required
via a library called libc++.a. This library is available in a C++ runtime
fileset called libc++.rte. Please refer to IBM documentation for more
information.
 

================================
IBM System i
================================
Not all products are available for IBM System i. Please refer to
www.pdflib.com regarding the use of AIX 32-bit binaries on i5 systems
with PASE.

Requirements: System i 7.2 and above

Functional restrictions on System i:
- ICU 50.1.1; only Unicode 6.2 supported
- WOFF2-compressed fonts not supported
- networking support not available
- C-based PDI/pCOS resource manager implementation instead of faster C++
  implementation
- Decompression of JPEG 2000 streams not supported


================================
IBM System Z
================================
Requirements:
z/OS 2.1 and above with USS (64-bit) or MVS (32-bit)

Functional restrictions on System Z:
- networking support not available


C/C++ binding
-------------
The library for C/C++ has been built with ibm-clang++64 (IBM Open XL C/C++ 2.1
for z/OS). Applications must be linked with XPLINK.

MVS
---
MVS versions of PDFlib GmbH products are not thread-safe.

Functional restrictions on MVS:
- networking support not available


================================
zLinux
================================
Requirements:
