introduction
Qwtplot3d is also an extension of qwt, used to draw three-dimensional model diagram, in the mechanical manufacturing, remote sensing mapping and model analysis and other fields of role is quite extensive.
This article is to undertake A probe into the internet of things--installation qwt of tool articles article, please read this article first.
Practice
3.1: Open the D:\qwt\MinGW\qwtplot3d\qwtplot3d.pro file and add the # include "stdio.h" header file to the Qwt3d_function.cpp file.
3.2: Add # include "Gl/glu.h" in Qwt3d_openglhelper.h
3.3: Modify the Qwtplot3d.pro file;
- Win32:template = Vclib
- Win32:template = Lib
Copy Code
3.4 After running, the Lib Library folder is generated under D:\qwt\MinGW\build-qwtplot3d-Desktop_Qt_5_4_1_MinGW_32bit-Debug. Copy the folder to the C:\Qt\ directory.
3.5 Run the self-brought instance. Because the Qwtplot3d source is relatively early, there is no support Qt5, so need to modify some files. 1) First modify the Common.pro file
- LIBS + = C:/qt/lib/qwtplot3d.dll
- # TEMPLATE = Vcapp
- # Qmake_lflags + =/nodefaultlib:msvcrt
Copy Code
2) Modify the D:\qwt\MinGW\qwtplot3d\examples\mesh2\src\designerworkaround.h file:
3) Run the program, the results found that the application will appear "program exception end" because the running program is missing the library file. Put the library file in the D:\qwt\MinGW\qwtplot3d\build-examples-Desktop_Qt_5_4_1_MinGW_32bit-Debug\bin directory, you can run the program properly.
The following is the program run interface, is not very shocking?
