Update: Adding "export CXXFLAGS=-fno-delete-null-pointer-checks" before building qtwebengine fixes qupzilla (respective to this "unable to load page" thing). FWIW, here is what I did: - build qt5 as per the book (skip-qtwebengine) - build the whole of LXQt except qupzilla. - install pciutils - build qtwebengine with the following instructions: - extract qt5 tarball again and change to the extracted directory - apply the NSS patch - run "./configure ..." as given in the book, except removing the "-skip-qtwebengine" flag - run "make module-qtwebengine". This just rebuilds part of qt, and then builds qtwebengine - run "make module-qtwebengine-install_subtargets". - run the instructions as in the book to remove reference to the build directory. - build qupzilla, as per the book.
