[Dcmlib] gcc

[Mathieu Malaterre]

Answering in english only, babelfish is your friend :)

You are right the lib for Qt on linux -as far as I know- are only compilerd using g++3. Since Qt is a c++ project it is extremly important that you stick to the same compiler the lib were compiler with. As you have seen g++2.95 cannot link to gcc3 lib (and same problem with gcc4 I believe).
A lot of our dashboard are running gcc3.x and as far as I can tell there is not a single warnings or compilation error. This is one of the most tested plateform. The only problem I can think of is that you tried to compiled gdcm within the very same directory after changing to gcc3. Therefore some old binary compiler with gcc2.95 were used to build a library with gcc3.x creating tons of problem at link time. Please create a directory per compiler this will save you a lot for time:

Typically:

  gdcm
  gdcm-gcc295
  gdcm-gcc33
  gdcm-gcc34
  gdcm-gcc40
  gdcm-icc70
  gdcm-icc81
  ...

J'ai donc mis a jour mon compilateur gcc et bien que j'obtiens toujours des erreurs dans la compilation de mon code, elles sont différentes, il y a certainement de l'espoir. Mon problème est que je n'ai jamais réussi à compiler mon programme gdcm avec gcc 3. J'ai du douwngrader à la 2 pour que ça fonctionne en fait. Pourtant je suis sur d'avoir lu quelque part que gdcm fonctionnait avec gcc 3. Ma version exacte est 3.4.1.

I did upgrate my compiler version and seeing my result compilation, I feel that I am on the good way. My trouble is that I ve never arrived to compile a gdcm project with gcc version 3. I had to downgrade my version to 2.96 to make it work. But I m sure I ve seen someone using gdcm with gcc 3. My exact version is 3.4.1.
