在Linux上构建VTK时收到错误"GLintptr尚未声明"

Question

在Linux上构建VTK时,我收到以下错误:

In file included from /usr/include/GL/glx.h:333:0,
             from /home/mildred/Work/3DKF/VTK/Rendering/vtkXOpenGLRenderWindow.cxx:31:
/usr/include/GL/glxext.h:480:143: error: ‘GLintptr’ has not been declared

Answer 1

解决方案是GLX_GLXEXT_LEGACY在构建期间定义.这已完成,但在Rendering/vtkXOpenGLRenderWindow.cxxVTK 5.x或Rendering/OpenGL/vtkXOpenGLRenderWindow.cxxVTK 6.x 的文件中进行了注释.

取消注释该行(这是例如包的ArchLinux补丁):

 #include "vtkgl.h"

或者,如果您不想侵入源代码,可以将标志添加到编译器命令行.例如,通过添加-DCMAKE_C_FLAGS=-DGLX_GLXEXT_LEGACY -DCMAKE_CXX_FLAGS=-DGLX_GLXEXT_LEGACY到您的cmake命令行.你的cmake命令看起来像:

cmake -DCMAKE_C_FLAGS=-DGLX_GLXEXT_LEGACY -DCMAKE_CXX_FLAGS=-DGLX_GLXEXT_LEGACY -Wno-dev ../VTK
