3 years ago 您好!
首先请先确定您已经安装了Eigen 3.2.5 以及 PCL 1.8
看这个报错,是缺少libproj.so这个库
首先检查一下在/usr/lib/x86_64-linux-gnu/下边是否有libproj.so.9这个库文件,如果有的话
sudo ln -s /usr/lib/x86_64-linux-gnu/libproj.so.9 /usr/lib/x86_64-linux-gnu/libproj.so
如果没有,尝试
sudo apt install libproj-dev
如果还有问题请在issue里更新, 我会及时跟进

3 years ago 感谢您的回复，解决完libproj.so这个问题后，出现了/usr/bin/ld: cannot find -lvtkproj4这样的问题
我参照https://github.com/PointCloudLibrary/pcl/issues/1594解决了，显示成功安装：
Scanning dependencies of target segmentation_ext

但是 在导入模块的时候出现以下问题：
import segmentation_ext Traceback (most recent call last): File "
", line 1, in ImportError: dynamic module does not define module export function (PyInit_segmentation_ext) 请问是什么原因呢

3 years ago 这个是由于编译segmentation ext的时候和运行calibration.py的时候使用了不一致的python环境(即使您这边activate的是同样的环境, 由于conda的某些配置, pybind11找到的也是不一致的环境, 这个问题在python3.x的环境下最有可能发生)
目前这个问题最快的解决办法是切换到python2.7, 在2.7下编译segmentaion_ext并在2.7下运行calibraiton
在python3下的解决办法晚些再恢复您,因为我这边自己的python3都是可以正常运行的,需要找一个环境来复现这个bug

3 years ago 您好, 找到问题了,这是一个由您本机的环境,PCL,Boost, conda,以及pybind11耦合在一起导致的及其复杂的bug.... 问题的表现就是在python3环境下编译segmentation_ext的时候, 无法找到正确的python解释器版本.
首先确保当前所在的conda环境是最终要编译segmentation_ext并运行calibration.py的环境
在命令行输入以下代码,
python -c "from sysconfig import get_paths;print(get_paths()['include'])"
它会输出一个路径, 类似/opt/conda/include/python3.7这样的,具体的输出要看您的环境. 复制这个路径.
include_directories(第2步复制的路径)
比如 include_directories(/opt/conda/include/python3.7), 具体的内容要看您第2步的输出.
然后保存.
python setup.py install
编译并安装segmentation_ext插件.

如果您想使用python3的话, 目前一个不太优雅的解决办法:
- 首先确保当前所在的conda环境是最终要编译segmentation_ext并运行calibration.py的环境
- 在命令行输入以下代码,
python -c "from sysconfig import get_paths;print(get_paths()['include'])"它会输出一个路径, 类似
/opt/conda/include/python3.7这样的,具体的输出要看您的环境. 复制这个路径.
- 在segmentaion/CMakeList.txt的第5行下边加这一句代码:
include_directories(第2步复制的路径)比如
include_directories(/opt/conda/include/python3.7), 具体的内容要看您第2步的输出.然后保存.
- 重新运行
python setup.py install编译并安装segmentation_ext插件.
如果仍然使用python2.7, 则不需要做更改.
Another a little bit hacky solution:
sudo mv /usr/include/python2.7 /usr/include/python2.7.keepsudo mv /usr/include/python2.7.keep /usr/include/python2.7Reference: https://github.com/SMRT-AIST/fast_gicp/issues/66#issuecomment-1078807527

-- Could NOT find PCL_APPS (missing: PCL_APPS_LIBRARY) 这个具体是啥原因呢
