All of those things are compiled statically. So is the application. We are developing on Windows, OS X and Linux boxes, but deploying almost only on Windows, so the cross-platform quality of the libraries is important to us and CMake makes it relatively easy to target all those platform.</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">Without going into static vs dynamic territory, I’ll say that our choice is based on ease of deployment to the hospital network where IT has lots of control, but we do not. So far, because of our choice of static linking, deployment is basically renaming the old .exe to keep an archive of all software that has been run clinical, and then put the new executable in place.</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">We’ve come to the stage where a GUI is something that would be practical. We have decided to go with Qt. We would like, if possible, to keep using static linking as a strategy, but as far as I can tell, trying to figure out how to use the new Qt5 macros, static linking of Qt is not exactly supported by CMake.</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">Here are a few questions for the list (hoping someone more knowledgable than me will read this and help):</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">1) Am I right when I say CMake, Qt and static linking don’t mix ?</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">I have tried on OS X.

In that case, is there a way to keep statically linking our other libraries (ITK, VTK, etc.) into our application and only dynamically link the Qt stuff ? If we can’t, it means we’ll have to create dynamic libraries of all our external libraries and link to them. Deployment will be much harder for us, given that we have zero experience with that.</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">Can you point me towards some tutorials (or documentation, but sometimes, documentation only gets you so far without examples…) ?</div><div id="bloop_sign_1423163985726296064" class="bloop_sign"></div><div id="bloop_sign_1423163985726296064" class="bloop_sign"><br></div><div id="bloop_sign_1423163985726296064" class="bloop_sign">Thanks</div><div id="bloop_sign_1423163985726296064" class="bloop_sign">Ghyslain</div><div id="bloop_sign_1423163985726296064" class="bloop_sign"><br></div><div id="bloop_sign_1423163985726296064" class="bloop_sign"><br></div><div id="bloop_sign_1423163985726296064" class="bloop_sign"><br></div><div id="bloop_sign_1423163985726296064" class="bloop_sign"><br></div><div id="bloop_sign_1423163985726296064" class="bloop_sign"><br></div></body></html>
