Unsolved Compile library and link active project when library code changes
-
Hi,
i have 2 qmake projects. One is the main application and one is a library.
Now i want to get the library recompiled AND relinked with my main application when a file inside the library has changed.
Somehow i always need to manually build the lib, then pseudo change a file in my main application (to trigger new linkage) to get the changes take effect.
There must be a way to define the dependency between my main application and my lib, but how?
Thank's for your help, and stay healthy...

Hi
You can use a subdir setup

@mrjj Thank you.
I now tried it with SUBDIR like in the link.My folder structure is as following:
application/
application/application.pro
application/src/lib/lib.pro
application/src/main-application/main-application.proAnd in the application.pro i set it up with SUBDIRS and .depends like this:
TEMPLATE = subdirs SUBDIRS = \ lib \ main-application lib.subdir = src/lib main-application.subdir = src/main-application main-application.depends = lib
Everything compiles fine.
But now the problem remains.
If i only change somethin inside lib and then rebuild only the lib get rebuild.
I want that after rebuilding the lib the main-application also gets linked against the new lib... Any ideas how to solve this? -
@Nando You have to put:
PRE_TARGETDEPS += \ $$PWD/../src/lib/libyourlib.a
in your apllication/application.pro file.
