====================================
System Requirements for PDFlib 8.0.1
====================================

This document describes the requirements for using the PDFlib 8 binaries on
various platforms. For a list of supported platforms and language bindings
please check www.pdflib.com.


================================
Note on 64-bit Intel platforms
================================
Intel uses the term "Intel 64" for a processor architecture which is
known by several other names:
- Intel formerly called it EM64T (after using IA-32e)
- Microsoft and Sun call it x64
- AMD calls it AMD64 (after using x86-64)
- Linux systems often refer to x86_64

PDFlib binaries for Intel 64 work on all architectures listed above.
They do not work on Intel Itanium (formerly called IA-64), which is
a separate architecture.
Because of the vendor-specific conventions we continue to use the term "x64"
instead of "Intel 64" in the context of Sun and Microsoft operating systems. 


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

Requirements:
Windows 2000/XP/Vista/7 on x86 or x64
Windows Server 2003/2008 on x86 or x64

.NET binding
------------
.NET Framework 2.0 or above

With ASP.NET 2.0 PDFlib.NET requires Full Trust level. It does not work
with any other trust level, including High or Medium Trust.

C and C++ bindings
------------------
Project files for the PDFlib programming samples are available for
Visual Studio 2005. VS2008 can convert these automatically.


================================
Linux
================================
Requirements: glibc-based system on x86, Intel 64, or IA-64

C and C++ bindings
------------------
x86: g++ 3.0 or above
IA-64/Intel 64: g++ 4.0 or above
LDFLAGS: "-pthread"

Java, Perl, PHP, Python, Ruby, Tcl bindings
-------------------------------------------
x86 and IA-64/Intel 64: libstdc++.so.6


================================
Mac OS X
================================
Requirements: Mac OS X 10.4 or above on PPC or Intel

C and C++ bindings
------------------
Xcode 2.4 or above, or g++ 3 or above

PHP binding
-----------
Mac OS X 10.6: no restrictions
Mac OS X 10.5 and earlier: see PDFlib-in-PHP-HowTo.pdf for restrictions


================================
FreeBSD
================================
Requirements:
x86: FreeBSD 7/8
Intel 64: FreeBSD 7/8


================================
AIX
================================
Requirements: AIX 5.2 or above

C binding
---------
XLC 8.0 compiler or above: you must use a thread-safe variant of the compiler
(such as xlc_r/xlC_r).

CFLAGS/CXXFLAGS/LDFLAGS for g++: "-mxl-compat -pthread"


================================
HP-UX
================================
Requirements: HP-UX 11 or above on PA-RISC or IA-64

C binding
---------
aCC or g++ compiler

CFLAGS/CXXFLAGS/LDFLAGS for aCC: "-mt" (required for multithreaded applications)

CFLAGS/CXXFLAGS/LDFLAGS for g++ on IA-64: "-lCsup",
	additionally for multithreaded applications: "-pthread" 

CFLAGS/CXXFLAGS/LDFLAGS for g++ on PA-RISC: "-lCsup_v2",
	additionally for multithreaded applications: "-pthread" 

PHP binding
-----------
In order to run the PDFlib binding for PHP on HP-UX you must install
operating system patches to fix an issue with shared library
loading and C++.

The following or corresponding superseding patches are required for HP-UX 11.11:

PHSS_33945 (s700_800 11.11 HP aC++ -AA runtime libraries)
PHSS_39749 (s700_800 11.11 ld(1) and linker tools cumulative patch)
PHCO_35743 (s700_800 11.11 libc cumulative patch)

The following or corresponding superseding patches are required for HP-UX 11.0:

PHSS_26945 (s700_800 11.x HP aC++ -AA runtime libraries)
PHSS_24303 (s700_800 11.00 ld(1) and linker tools cumulative patch)
PHCO_28425 (s700_800 11.00 libc cumulative patch)


================================
Solaris
================================
Requirements: Solaris 8 or above on x86, x64, or sparc

C binding
---------
CFLAGS/CXXFLAGS/LDFLAGS for Sun Studio compiler: "-mt -lpthread"
CFLAGS/CXXFLAGS/LDFLAGS for g++: "-pthread"


================================
i5/iSeries
================================

================================
zSeries
================================
Requirements:
z/OS 1.6 or above with MVS, USS, or zLinux
The MVS version of PDFlib is not thread-safe.
OS/390 2.10 or above
We currently do not support 64-bit applications on z/OS.

C/C++ binding
-------------
CFLAGS/CXXFLAGS: -W "c,float(ieee)"
