Hi All,

I am new to ImageMagik, and I want to link it statically to my C Code.

Detector: Detector.cpp TDCommon.cpp ./SVMLight_Classifier/svm_common.c
g++-4.1 Detector.cpp TDCommon.cpp ./SVMLight_Classifier/svm_common.c `Magick++-config --cppflags --cxxflags --ldflags --libs` -o "Detector" -I "./SVMLight_Classifier/"

This is the part of my make file, which I use to compile. It all works fine when there is the same version of ImageMagik, otherwise it wont work.

This code is not statically compiled, and if some could let me know what modifications that I need to do to make a static linking, It will be great

Thanks!
Vikram

The default ImageMagick build is usually dynamic. To build a static version of ImageMagick download the source and type:

• cd ImageMagick-6.4.4
  ./configure --disable-shared
  make
  make install

Now when you use the Magick++-config script, your program will link to the static version of the ImageMagick library.

It is never too late to say a thanks.

In order to be very sure that the program is statically compiled, I used --static switch.

g++ Transform.cpp --static `Magick++-config --cppflags --cxxflags --ldflags --libs` -o "Transform"

This was the result:

So, how do I make it work.
Without the static switch, it compiles fine, but it is requires libraries at runtime.

To have a full static distribution of ImageMagick you not only need to build ImageMagick statically but also any library it links to (i.e. jpeg, png, X11, etc.).

Can you please let me know, how do I do that?

Static linking is beyond the scope of this discussion server since it has little to do with ImageMagick and mostly to do with compiler / linking issues. You may want to seek advice from the gcc or Linux user forums.

Ok, thank you. However, I will report if my issue is solved.

If I execute these command to make static build of ImageMagick
>>cd ImageMagick-6.4.4
>>./configure --disable-shared
>>make
>>make install

I get the following errors during compile time in my C++ code with which I am linking Magick++. The error is list is too long, and I just pasted a small snippet of it. Any solutions?

Try installing ImageMagick 6.4.5-9, the latest release. It has updated configure files that may make a difference. On our systems with 6.4.5-9 and the --disable-shared option, ImageMagick builds and installs without complaint.

Thanks, I will try this in a couple of hours and report back
