I ran podofouncompress over the attached simple file, but I get an
error in PdfFlateFilter::BeginDecodeImpl.
If I look at m_stream, I see bad pointers in next_in, next_out and msg.
Data type is -842150451.
Any help greatly appreciated.

Hi Craig,
Now I'm making some progress - thanks for the help.
Just to clarify I understood that the idea of cmake is to make the
project files for Visual Studio. But I thought that cmake was part of
MinGW (like the unix tools that run under cygwin). Having the
cmake.org URL in the readme would be useful for newbies to the cmake
and mingw like me to get going.
I also find the revised form of this paragraph very clear:
"If your application or library uses Visual Studio, CMake can be used to
build a Visual Studio project you can use. Alternately, if you are using
MinGW for your existing code, CMake can make you a MinGW makefile to
build a mingw compatible version of PoDoFo."
I've installed freetype and zlib from gnuwin32, and run cmake. But it
can't find freetype.lib - which is missing from c:\program
files\gnuwin32\lib. The output from cmake is below. I tried
downloading the freetype-2.3.5 sources, creating a visual studio
project with jam and then copying the freetype235MT.lib into the
gnuwin32 folder as freetype.lib. This allowed the cmake project
generation to complete - but visual studio can't link against the
freetype lib.
Do you know where I could get a working freetype lib from or what
settings I should use to compile freetype correctly?
Many thanks,
Ed.

You do not need MinGW - you can and probably should use Visual Studio if
you're used to it and prefer it. Remember that C++ code is not binary
compatible between different compilers, so if you build your main app
with Visual Studio 6 you must also build PoDoFo with Visual Studio 6, as
explained in the "CMake builds with Windows" section of the README.
As for CMake - there's no "CMake for Visual Studio". CMake is standalone
and targets a variety of tools on each platform. I have failed to
document installing CMake as part of the PoDoFo install instructions -
partly because it's amazingly easy.
Go to cmake.org
Download the current CMake binary release
Install it
You're done. It auto-detects MinGW, various Visual Studio versions, etc;
no further setup should be required.
Looking at the install instructions - I've tried the provided VS project
files route already. So I guess I'll now try generating Visual Studio
project files with CMake. But I'm a little confused by the second
sentence - are MinGW Makefiles the same thing as using CMake to
generate Visual Studio project files?
No. MinGW is completely different to Visual Studio - it's a port of the
GNU C/C++ compiler to Windows.
The instructions cover several ways to build on Windows, because Windows
developers use a variety of tools and work in a variety of ways. In your
case, you want to use CMake to generate Visual Studio project files. You
don't need to have anything to do with MinGW.
"On Windows, it is recommended that you use CMake to generate Visual Studio
project files appropriate for your VS version and your libraries. You
can also generate NMake builds or MinGW Makefiles (see "Installation with CMake").
Read "CMake builds on Windows" and "CMake builds on Windows with Visual
Studio" in the README. If anything is still unclear, let me know.
The point above could perhaps be more explicitly stated as:
"If your application or library uses Visual Studio, CMake can be used to
build a Visual Studio project you can use. Alternately, if you are using
MinGW for your existing code, CMake can make you a MinGW makefile to
build a mingw compatible version of PoDoFo."
Alternately, Windows users can use the provided Visual Studio
Solution/Project
files after placing the other libraries in a directory inside of the podofo
directory."
Yep, that's hopelessly out of date and has been removed from the current
development version, along with the project file referred to.
