CGAL_USE_BASIC_VIEWER
CGAL_USE_BASIC_VIEWER
我正在尝试使用 .off 文件运行 libqglviewer 多选示例，但它显示了以下问题：无法绘制，因为未定义CGAL_USE_BASIC_VIEWER。
所以我补充说 QMAKE_CXXFLAGS +=-DCGAL_USE_BASIC_VIEWER 到 .pro 文件它解决了现有问题，但显示了很多与 Basic_viewer_qt.h 相关的错误

有什么帮助吗？请
您没有使用正确的 QGLVIewer。CGAL_USE_BASIC_VIEWER仅在libQGLViewer的CGAL实现中是必需的，它只应该在CGAL图形中使用。检查路径并避免包含 CGAL 的路径。
