[Qgis-user] Debugging QGIS using MSVC

[Sjur Kolberg]

Rob,

I haven't actually built QGIS myself, but in general you need to make all necessary dlls available to your .exe file, also for debugging. This means in the same folder, or in a folder that's included in your path. Beware that these may include both dlls that you compile as a part of the QGIS solution, and pre-compiled dlls that you have downloaded in binary form.

It is quite common that multi-project solutions in Visual Studio put their binaries in project-specific folders, typically /Debug and /Release at the same level as each .vcproj file resides. This leaves it to you to (manually or by setting some poist-build events) copy all dlls and .exes into the right (common) place.

VS will always ask for executable when you try to debug a dll; naturally since a dll needs to be run by an application (.exe file). qgis.exe will be the natural choice here, be sure to pick the right of the debug or release version.

I tend to create a /bin catalogue (and a /debbin, for debug versions) at the solution directory level (where the .sln file is) , and either direct or copy the linker output (.dlls and .exes) here.

BTW, I also copy all .lib files to a common /lib folder (/deblib), and the .h files to a common /include folder, and make sure that either VS or all the projects look in these folders for libraries and include files. This seems to be OK in your case, if everyting builds nicely.

Good luck,

Sjur K :-)

Dear list,

It has been quite a struggle to get QGIS to compile on my PC using MS Visual Studio 8 (2005). At the moment, it seems like all binaries compile correctly, but all in separate folders... Executing QGIS.exe ( (...)\qgis-1.3.0\build\src\app\debug\qgis.exe) results in a message of missing dlls.

How am I supposed to Run / Debug QGIS from MSVC? Pressing the "play" button, MSVC asks for which executable file to be used for the debug session.

Any help is appreciated. I guess I need some post-linking process that copies newly built QGIS files? And some more static Qt binaries.
