Debug crash when using Visual Studio

[steveq]

Hey All,

I have written a small program to test out ImageMagick.

It is a dialog based MFC app.

If I run the program in release mode, it works perfectly, loading an image and writing it back out in a different format.
However in debug mode, it crashes on the read(), the exception doesn't even get trapped!

Has anyone had similar issues and found a sloution please?

Thanks heaps,

Steve Q.

You may need to build ImageMagick from source in debug mode to use within a debug application. We're not completely sure because we are primarily Linux developers.

[steveq]

Thanks magick,

No worries, where do I get the source and is there a visual studio workspace included with it?

Thanks heaps,

Steve Q.

See http://www.imagemagick.org/script/insta ... hp#windows for the ImageMagick Windows source and build instructions.

[steveq]

Thanks again magick,

Your support is amazing!

I really appreciate your help.

Thanks magic,

Rebuilding in Visual Studio fixed the crash!

Hi

Did you find a solution. I'm having the exact same problems - however, a recompile of the imagemagick framework doesn't work here.

Hey Preben,

I downloaded the Windows source, then I built them in VS.

Make sure you are using the Debug DLLs and .lib and not the release versions when running in debug mode. I just copied the debug DLLs into the debug directory where the final .exe was built.

All is fine now and I can run the debug code happily!

Hmm... Yeah I'm having some trouble with that...

I used the configure.exe file to construct a project under the VisualMagick folder. I selected the 8bit per colour instead of the 16bit and uses a static single threaded library.
I'm gonna try the new version now - I have been using 6.5.2-Q8 version. However, I don't think it'll change anything.

[prebenh]

Are you using any special settings for your project - or just the default ones that Visual Studio provides for you!

- Preben

[steveq]

Yeah.... I used the 16bpp version, sorry I can't be of more help.

[steveq]

No I jut used the configuration that was built for me... I didn't change anything.

[prebenh]

Maybe you can help anyway... When compiling my own project everything seems fine, however debugging gets errors

How are the settings for your project?
I unzipped the ImageMagick library to the root of my computer:
C:\ImageMagick-6.6.0

- added C:\ImageMagick-6.6.0\VisualMagick\bin to the system PATH

Set up my project to use:
Linker library directories:
- C:\ImageMagick-6.6.0\VisualMagick\bin
- C:\ImageMagick-6.6.0\VisualMagick\lib

and Linker libraries:
- CORE_DB_magick_.lib
- CORE_DB_Magick++_.lib

and Include directories
- C:\ImageMagick-6.6.0\
- C:\ImageMagick-6.6.0\Magick++\lib

and I set up the preprocessor definitions for the project:
- NOMINMAX;NDEBUG;WIN32;_CONSOLE;_VISUALC_;NeedFunctionPrototypes;_DLL;_MAGICKMOD_;_WINDOWS;_CRT_SECURE_NO_WARNINGS;_CRT_NONSTDC_NO_WARNINGS



When debugging I get this stack trace:

What is wrong?

Hey Preben,

My pre-processor directives looks like this:
WIN32;_WINDOWS;_DEBUG;OPJ_STATIC

I only have the one link lib:
"..\ImageMagick-6.5.9\VisualMagick\lib\CORE_DB_Magick++_.lib"

Plus the includes...

Then I did this:
#include "Magick++.h"

using namespace std;
using namespace Magick;

And that's about it (apart from copying the debug DLLs into my debug dir)?

I can try and create a blank project that compiles and works for you if you need it?

[prebenh]

I'll just try what you've done and see what happens (tomorrow).

Did you initialize Imagemagick as described in the documentation?
http://www.imagemagick.org/Magick%2B%2B/
with
InitializeMagick(path)

Which Visual Studio version are you using?
