关于SO本身,已经有很多关于VSCode IntelliSense的问题,例如,que1、que2、que3等。然而,他们主要谈论IntelliSense在一般情况下不起作用;不为STL工作;等等
另一方面,在我的情况下,我已经在使用Microsoft的VSCode C/C++扩展,IntelliSense可以很好地用于所有不同的内置类、函数、STL等。但是,当涉及到PCL
(点云库(时,不知怎的,神秘地,IntelliSenses不起作用。
如果您熟悉PCL
,那么一定知道它的大多数语法都太大了。由于IntelliSense不起作用,如果你在键入每一个字符时不集中注意力,例如,就很有可能出现拼写错误
pcl::PointCloud<pcl::PointXYZRGB>::Ptr point_cloud_ptr (new pcl::PointCloud<pcl::PointXYZRGB>);
事实上,即使是那些变量和函数的自动完成也不起作用——也就是说,从上面的例子来看,每次我想使用point_cloud_ptr
时,我都必须手动键入它的每一个字符
那么,我该怎么解决这个问题呢?还是PCL
不可能?
注意:我在Ubuntu 16和Ubuntu18上都面临这个问题。我使用sudo apt install libpcl-dev
安装了PCL
,头文件位于/usr/include/
目录中。
在GitHub上尝试了不同的东西并获得了Microsoft VSCode(和C/C++扩展(团队的帮助后,IntelliSense似乎不起作用可能是因为扩展无法找到PCL头。
在Ubuntu的情况下,PCL标头通常存储在/usr/include/pcl-<version>
中。在我的Ubuntu 18.04中,我有pcl-1.8
。因此,理想情况下,在c_cpp_properties.json
文件的"includePath"
下添加"/usr/include/pcl-1.8/**"
应该可以工作。例如
{
"configurations": [
{
.
.
"includePath": [
"${workspaceFolder}/**",
"/usr/include/pcl-1.8/**"
],
.
.
.
}
],
"version": 4
}
在"/usr/include/pcl-1.8/**"
中,**
用于/usr/include/pcl-1.8/
目录下的递归搜索。然而,当我发布这个问题时(我想到今天为止也是如此(,它不起作用。它无法遍历pcl-<version>
目录下的子目录。因此,替代解决方案如下:
解决方案01:(如果只想将更改应用于当前项目,请使用此解决方案(
打开C/C++扩展配置文件:c_cpp_properties.json
(在Linux上,按Ctrl+Shift+p并选择C/C++: Edit Configurations (JSON)
(
现在,由于递归搜索不起作用,另一种方法是指定includePath
:下的所有子目录
{
"configurations": [
{
.
.
"includePath": [
"${workspaceFolder}/**",
"/usr/include/eigen3",
"/usr/include/pcl-1.8",
"/usr/include/pcl-1.8/pcl",
"/usr/include/pcl-1.8/pcl/2d",
"/usr/include/pcl-1.8/pcl/apps",
"/usr/include/pcl-1.8/pcl/common",
"/usr/include/pcl-1.8/pcl/compression",
"/usr/include/pcl-1.8/pcl/console",
"/usr/include/pcl-1.8/pcl/features",
"/usr/include/pcl-1.8/pcl/filters",
"/usr/include/pcl-1.8/pcl/geometry",
"/usr/include/pcl-1.8/pcl/impl",
"/usr/include/pcl-1.8/pcl/in_hand_scanner",
"/usr/include/pcl-1.8/pcl/io",
"/usr/include/pcl-1.8/pcl/kdtree",
"/usr/include/pcl-1.8/pcl/keypoints",
"/usr/include/pcl-1.8/pcl/ml",
"/usr/include/pcl-1.8/pcl/modeler",
"/usr/include/pcl-1.8/pcl/octree",
"/usr/include/pcl-1.8/pcl/outofcore",
"/usr/include/pcl-1.8/pcl/people",
"/usr/include/pcl-1.8/pcl/range_image",
"/usr/include/pcl-1.8/pcl/recognition",
"/usr/include/pcl-1.8/pcl/registration",
"/usr/include/pcl-1.8/pcl/ros",
"/usr/include/pcl-1.8/pcl/sample_consensus",
"/usr/include/pcl-1.8/pcl/search",
"/usr/include/pcl-1.8/pcl/segmentation",
"/usr/include/pcl-1.8/pcl/stereo",
"/usr/include/pcl-1.8/pcl/surface",
"/usr/include/pcl-1.8/pcl/tracking",
"/usr/include/pcl-1.8/pcl/visualization"
],
.
.
.
}
],
"version": 4
}
解决方案02:(如果您想在所有项目中全局应用更改,请使用此解决方案(
由于C/C++配置文件:c_cpp_properties.json
特定于每个项目,因此编辑只会将更改应用于当前项目。因此,要在所有项目中应用更改,必须先更新settings.json
,然后更新c_cpp_properies.json
。
打开settings.json
并添加以下文本:
"C_Cpp.default.includePath": [
"/usr/include/eigen3",
"/usr/include/pcl-1.8",
"/usr/include/pcl-1.8/pcl",
"/usr/include/pcl-1.8/pcl/2d",
"/usr/include/pcl-1.8/pcl/apps",
"/usr/include/pcl-1.8/pcl/common",
"/usr/include/pcl-1.8/pcl/compression",
"/usr/include/pcl-1.8/pcl/console",
"/usr/include/pcl-1.8/pcl/features",
"/usr/include/pcl-1.8/pcl/filters",
"/usr/include/pcl-1.8/pcl/geometry",
"/usr/include/pcl-1.8/pcl/impl",
"/usr/include/pcl-1.8/pcl/in_hand_scanner",
"/usr/include/pcl-1.8/pcl/io",
"/usr/include/pcl-1.8/pcl/kdtree",
"/usr/include/pcl-1.8/pcl/keypoints",
"/usr/include/pcl-1.8/pcl/ml",
"/usr/include/pcl-1.8/pcl/modeler",
"/usr/include/pcl-1.8/pcl/octree",
"/usr/include/pcl-1.8/pcl/outofcore",
"/usr/include/pcl-1.8/pcl/people",
"/usr/include/pcl-1.8/pcl/range_image",
"/usr/include/pcl-1.8/pcl/recognition",
"/usr/include/pcl-1.8/pcl/registration",
"/usr/include/pcl-1.8/pcl/ros",
"/usr/include/pcl-1.8/pcl/sample_consensus",
"/usr/include/pcl-1.8/pcl/search",
"/usr/include/pcl-1.8/pcl/segmentation",
"/usr/include/pcl-1.8/pcl/stereo",
"/usr/include/pcl-1.8/pcl/surface",
"/usr/include/pcl-1.8/pcl/tracking",
"/usr/include/pcl-1.8/pcl/visualization"
]
打开c_cpp_properties.json
并更新includePath
:
{
"configurations": [
{
.
.
"includePath": [
"${workspaceFolder}/**",
"${default}"
],
.
.
.
}
],
"version": 4
}
p.S.我在微软的C/C++扩展的官方GitHub问题页面上问了同样的问题,最终找到了我上面提到的解决方案(但不是理想的解决方案(。
以下是获取更多信息的链接:https://github.com/microsoft/vscode-cpptools/issues/5843
因为VSCode总是告诉我它找不到像pcl/PCLHeader.h
这样的依赖项。所以我试着把/usr/include/pcl-1.10/pcl
复制到/usr/include/
,结果成功了。
