qmake: How do I copy .dll/.so's to the output directory?
Question
I have a Qt-project that builds a dll/shared-library and another Qt-project that tests the library.
Is there any good way to have qmake copy the dll to the output-folder of the test-project?
Solution
Add this to your pro file:
target.path = ../testProject/$$TARGET
INSTALLS += target
OTHER TIPS
# Copy the dynamic library.
win32 {
QMAKE_PRE_LINK=copy /Y lib\qextserialport\src\build\qextserialportd.dll debug\ & copy /Y lib\qextserialport\src\build\qextserialport.dll release\
}
else {
# TODO: Unices
}
This works, for the QextSerialPort library. Supports Qt's debug_and_release
mode.
QMAKE_POST_LINK
also works, but will throw an error if you're trying to run the app immediately: then your .dll will be copied too late. QMAKE_PRE_LINK
does copy it in time.
I use INSTALLS, like so. (qmake documentation)
This may not be a 'good' way but it may do the trick.
QMAKE_POST_LINK += some shell command to copy the dll
You can use DESTDIR
keyword as it is said in qmake files documetation in Qt 4.
