How to rebuild code in qtdatavis3d?
I've got Qt 5.13.0 on unbuntu downloaded from the online installer. I have modified 5.13.0/Src/qtdatavis3d/src/datavisualization/utils/texturehelper.cpp. How do I rebuild all of the Qt libraries, etc to incorporate this change in my apps? I do not see a Makefile at the top level...
There's no need to rebuild all of Qt. Just build and install the module.
Building a Qt module is the same procedure as building any other qmake based project. You can even load the module in Qt Creator and build it there.
@sgaist - Assume I want to rebuild qtdatavis3d from the linux command line, which directory do I 'cd' to, and what command do I invoke? Thanks!
I tried the following:
# Go to qtdatavis3d subdirectory cd Qt/5.13.0/Src/qdatavis3d # Generate make file qmake qdatavis3d.pro # Clean and remake the module make clean make # Puts generated libraries into lib/ subdirectory sudo make install # Copy libraries from lib/ to /usr/local/5.13.0/lib
I then use qtcreator to clean and rebuild my app that uses qtdatavis3d module, but I do not see my changes, i.e. they don't seem to have taken effect. While 'make install' copies the module libraries to /usr/local/Qt-5.13.0/lib, it turns out that that qtcreator is linking against libraries in Qt/5.13.0/gcc_64/lib - and 'make' does not update those libraries. So I had to manually copy the new libraries there:
cp lib/* ~/Qt/5.13.0/gcc_64/lib/.
You should always use the full path to the qmake binary of the Qt version you want to use to build your project/library/module.
