You can use a qmake function for reusability: # Copies the given files to the destination directory defineTest(copyToDestdir) { files = $$1 for(FILE, files) { DDIR = $$DESTDIR # Replace slashes in paths with backslashes for Windows win32:FILE ~= s,/,\\,g win32:DDIR ~= s,/,\\,g QMAKE_POST_LINK += $$QMAKE_COPY $$quote($$FILE) $$quote($$DDIR) $$escape_expand(\\n\\t) } export(QMAKE_POST_LINK) } then use it … Read more
You should install package “libgl1-mesa-dev”: sudo apt install libgl1-mesa-dev
If you are using qmake, the standard Qt build system, just add a line to the .pro file as documented in the qmake Variable Reference: INCLUDEPATH += <your path> If you are using your own build system, you create a project by selecting “Import of Makefile-based project”. This will create some files in your project … Read more
Finally I am starting to be happy. When adjusting this question I had to try all the ways how to define LIBS. Listing them manually helped, at first I wrote them somehow wrong. This is how it works finally: LIBS += -LC:\\Programs\\opencv24\\opencv_bin2\\bin \ libopencv_core240d \ libopencv_highgui240d \ libopencv_imgproc240d \ libopencv_features2d240d \ libopencv_calib3d240d \
The proper way to do this is like this: LIBS += -L/path/to -lpsapi This way it will work on all platforms supported by Qt. The idea is that you have to separate the directory from the library name (without the extension and without any ‘lib’ prefix). Of course, if you are including a Windows specific … Read more
In the constructor, you set root to Null. Then in insertNode, you do: cursor = root; while(cursor->getNextNode()) You need to allocate a root node, or deal with it being Null.
