Hi, I am getting the following error while running make- .... [ 84%] Generating moc_onlinefusionviewer.cxx Scanning dependencies of target onlinefusion [ 88%] Building CXX object src/CMakeFiles/onlinefusion.dir/onlinefusionviewer_main.cpp.o In file included from /usr/local/include/QGLViewer/vec.h:32:0, from /usr/local/include/QGLViewer/quaternion.h:26, from /usr/local/include/QGLViewer/keyFrameInterpolator.h:29, from /usr/local/include/QGLViewer/camera.h:27, from /usr/local/include/QGLViewer/qglviewer.h:26, from /home/initial/fastfusion/src/onlinefusionviewer.hpp:11, from /home/initial/fastfusion/src/onlinefusionviewer_main.cpp:29: /usr/local/include/QGLViewer/config.h:43:34: error: too many decimal points in number : Use a version prior to 2.7.0 to remove this constraint ^ /usr/local/include/QGLViewer/config.h:80:25: fatal error: QOpenGLWidget: No such file or directory compilation terminated. src/CMakeFiles/onlinefusion.dir/build.make:67: recipe for target 'src/CMakeFiles/onlinefusion.dir/onlinefusionviewer_main.cpp.o' failed make[2]: [src/CMakeFiles/onlinefusion.dir/onlinefusionviewer_main.cpp.o] Error 1 CMakeFiles/Makefile2:128: recipe for target 'src/CMakeFiles/onlinefusion.dir/all' failed make[1]: [src/CMakeFiles/onlinefusion.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2

Does anyone know how to resolve it? Thanks in advance

I just change the QOpenGLWidget into QGLWidget and passed. This link shows the answer. https://askubuntu.com/questions/934836/fatal-error-qtwidgets-qopenglwidget-no-such-file-or-directory But after that more errors occurred. Plenty of grammar problems of c++

Try to install and use prior version, such as http://www.libqglviewer.com/src/libQGLViewer-2.6.3.tar.gz

Also that README.md is better https://github.com/greatwallet/fastfusion I made it works with Ubuntu 20.04
