Question 1: a series of unresolved external symbol.
This problem has troubled me one day, said the Internet looking for most is to remove, empty, recompile, but to me does not help, finally found a solution, that is my VS the Additional Dependencies less contains several libraries . Mainly the bottom of several libraries, I put my additional dependencies here to be a backup. Then solve the problem, of course, this is not the solution in QT creator, this is it me when new VS QT, when dragged into QVTKwidget, were unable to resolve the problem of compiling arise.
In the QT creator also have to include it lib, as follows
LIBS += E:\python\python-pcl\PCL1.8.1\3rdParty\Boost\lib\*.lib
LIBS += E:\python\python-pcl\PCL1.8.1\3rdParty\VTK\lib\*.lib
Before those questions did not, there was a new problem:
I'm the VTK when I follow online tutorials into the OpenGL2 compiled with cmake https://blog.csdn.net/GreenHandCGL/article/details/82312940 OpenGL lead, then recompiled VTK, this will be replaced OpenGL2 OpenGL other steps unchanged.
And then there was this question:
this is not a lack of dll, dll I will release all put in to produce the C: \ Windows \ System32, after the problem is solved.
