Lor*_*ora 4 boost cmake windows-10 ros2
当尝试从 ros2 编译cv_bridge时,我需要帮助解决这个 cmake boost python3 find 问题,它使用名为colcon的构建工具,然后使用 CMake。colcon 构建错误消息:
> colcon build --symlink-install --merge-install
...
--- stderr: cv_bridge

libboost_python38-vc142-mt-gd-x64-1_76.lib为libboost_python38.lib和libboost_python3.lib我已经没有想法了,请提供任何帮助,将不胜感激!
我在 Fedora 上编译 ros noetic 时遇到了类似的问题。它能够找到,Boost 1.76.0所以我认为问题应该出在 python 组件上。我猜是找不到合适的libboost_python版本。因此,当我检查该库时,我在以下位置找到了它:/usr/lib64/libboost_python310.so。所以我更新了cv_bridge/CMakeLists.txt专门使用 3.10 版本:
if(NOT ANDROID)
find_package(PythonLibs)
if(PYTHONLIBS_VERSION_STRING VERSION_LESS "3.8")
# Debian Buster
find_package(Boost REQUIRED python37)
else()
# Ubuntu Focal
# Because I am using python 3.10 I updated
# this line. If you are using a version less
# than 3.8, then update the previous line
# Updated line
find_package(Boost REQUIRED python310)
endif()
else()
find_package(Boost REQUIRED)
endif()

将其设置为专门查找 3.10 版本解决了该问题,并且我能够编译。
编辑:没有意识到问题是针对 Windows 平台的,但这个答案可能仍然有帮助
