A simple "Reveal in finder" for a library can help you.

I built the libraries very well,

but when set the active directory to instal, and rebuid it raise the following error

file INSTALL cannot find "/dcmtk-3.6.0/xcode/dcmdata/apps/Debug/dcm2pdf".
Call Stack (most recent call first):

dcmdata/cmake_install.cmake:34 (INCLUDE)

cmake_install.cmake:50 (INCLUDE)

make: *** [install_buildpart_0] Error 1

Command /bin/sh failed with exit code 2

do you have any suggestion to fix that

-- I solved that by copying them manualy

I tried to create sample examples but it gave me error could u check the following linke viewtopic.php?t=2847

can I send the complete objective- c to the forum

dcm2pdf is a executable,you don't need to compile it, remove it in your targets.

but if it's the case, what library have you this error?

For your example, think to link at your project the good library with the good architecture, don't forget IOS use "arm" for device and "I386" for simulator.

I added all the libraries and I told the project to add refrence to it , is this the link you talk about ,

Do you compile dcmtk for IOS simulator and test the libs for the device?

The libs are not universal binary.

@ali - it sounds like you have exactly the same issues as I have. I have managed to compile the DCMTK LIB in xcode and it runs without errors when the base SDK is set to the latest mac OSX. However, once the base sdk is changed to the latest iOS sdk (4.2) it throws the errors of missing the dreaded libc.h file. Like you I cannot find it. Did you have any luck solving the problem and get any further of actually getting an app to display a .dcm image? ..... if only there was a demo source code so I can learn from it lol

@francois - thank you for all the useful posts (please keep them coming)

Regards,

Rick.

Comment the line

To show Dcm files use OpenGLEs, it's work fine.

Dcm file is a simple texture on a simple surface.

Excuse my lack of knowledge... OpenGLEs ?

I will add this to the list of things to also look up

OpenGL ES

It's opengl for embedded devices.

To read

@Francois

Thanks for the links.... So am I right in thinking using OpenGLEs will display a DICOM image and I don't need additional libraries to just display a simple image in a UIimageviewer? I just need a basic app to display a DICOM image and am starting to get very confused

Thanks for all your help.

I already try to use UIimageviewer without success (not good color/size).
When you read a dicom file, you get rawData with a particular format (8 bits, gray).

Apparently, IOS API doesn't managed perfectly this format (or it's my bad)

So, Yes, using openglES works.

I worked long time to show a simple dicom file, so i will try to help you.

Dear Francois,

I am glad someone else had no success with UIimageviewer to display a DICOM image

I have been playing around with the OpenGLes all weekend - I particularly like the GLImageProcessing sample code - if I could get a Dicom showing in this format it is exactly what I am aiming to do. The current DICOM viewers available on the iphone / iPad are far to complicated for what I need. My job would be made a lot easier if I could just view my own DCIOM's without being logged into a PACS server. Oh, what fun it is to be a beginner programmer!! lol

Pointers in the right direction are always welcome.

Kindest regards & keep up the good work on the skuld project!!

Rick.

It's not so complicated.

When you read a dicom file, you can get rawData (in 8 bits) of the picture.

So, with that, you can use the data like a texture for openGles.

Create a simple surface and put the picture/texture on the surface.

OK.... I have spent a further week researching and playing around with textures etc....

re:

Does anyone have some sample source code that I can play around with -this is driving me nuts!!

I have tried Papyrus, DCTMK and OpenGLes - have I missed anything!?!
