Setup Ptex with D3D11 and Visual Studio

[Elberion]

Hi everyone!
I am very new to this i am trying work with ptex with D3d11 and Visual
Studio.
The thing is i have included the Ptex files downloaded from "ptex.us"
into my project. So far so good, but when i compile i get:

f:\kit\ma\renderpacktests\sdkmeshdemo\ptex\ptexreader.h(39): fatal
error C1083: Cannot open include file: 'zlib.h': No such file or
directory
1> PtexHalf.cpp
1>f:\kit\ma\renderpacktests\sdkmeshdemo\ptex\ptexhalf.cpp(39): warning
C4273: 'f2hTable' : inconsistent dll linkage
1> f:\kit\ma\renderpacktests\sdkmeshdemo\ptex
\ptexhalf.h(117) : see previous definition of 'public: static unsigned
short * PtexHalf::f2hTable'
1>f:\kit\ma\renderpacktests\sdkmeshdemo\ptex\ptexhalf.cpp(39): error
C2491: 'PtexHalf::f2hTable' : definition of dllimport static data
member not allowed
1>f:\kit\ma\renderpacktests\sdkmeshdemo\ptex\ptexhalf.cpp(40): warning
C4273: 'h2fTable' : inconsistent dll linkage

etc.

I can't find the zlib.h anywhere in the source code i downloaded from
ptex.us.

So summarizing:
Can someone tell me what i need to do to run PTex with Visual Studio?

Thank u very much in advance
Elberion.

zlib is a separate library available at zlib.net. This is a widely
used data compression library and is unrelated to Ptex. You can
download it as source code or as a precompiled dll.

I've heard of this issue but I don't know enough about Windows DLLs to
know how people are getting around it (we only use Linux at Disney).
One option might be to compile Ptex directly into your application
insetad of trying to make it into a DLL. Another might be to just
compile the PtexHalf class directly into your application (if you even
need it) and change the declaration of PtexHalf to not export those
symbols. Btw, if someone wants to submit a patch that makes this
problem go away, I'd happily accept it ;-) You might also try using
CMake. There are Ptex forks on github that have been able to build
Ptex for windows using CMake.

The dll linkage thing usually has to do with trying to link a multi-threaded app to a single-threaded dll (or vice versa). Should just be a setting in your linker options.

First of all thank you very much for your answers.

I have used cmake to make a visual studio project out of the ptex,
downloaded from (ptex.us). Executing this, i've got a lot of compiling
errors that prevented the program from creating the Ptex.lib file.
I could correct a lot of them(thx @brentb) but the dll linkage errors
still remain.

@Ron: I have searched in visual studio's project linker options, but i
haven found anything that looks like "Don't link multithreaded to
single-threaded dll"

Does someone know hot to get pass these errors?
Thank you again for the fast reply

I have been looking how to solve this and i have changed this piece of
code on PTexHalf.h:

# ifdef PTEX_EXPORTS
# define PTEXAPI __declspec(dllimport)
# else
# define PTEXAPI __declspec(dllexport)

So that "define PTEXAPI __declspec(dllexport)" is executed. The
inconsistent ddl linkage warning is gone as for the "definition of

dllimport static data member not

allowed " error. But now i have unresolved externals which i dont know
how to solve:

I hope someone can help me, i am pretty excited about starting with
Ptex.
