[Error] Windows Build issue with BOOST #401

Open ShivamPR21 opened 3 years ago

ShivamPR21 commented 3 years ago

Hi! all I am new to windows environment with ROS ecosystem.

Here facing problems with windows build of cv_bridge stating

: fatal error LNK1120: 3 unresolved externals

I have tried some of the open PRs for fixes, but that didn't work #390

here is complete output:

It looks like you are trying to use Boost 1.76 but you have Python 3.8 - which the latest version of boost that uses python 3.8 is 1.74.

Either upgrade your python version or downgrade your boost version and you should be good.

The error is because the boost version you have installed was built with Python 3.9.

flynneva commented 3 years ago

i'd recommend using the link in the PR you linked to above to download a pre-compiled Boost 1.74. once you do and set your proper environmental variables it should work.

I am actually facing the same issue with Boost 1.74 and Python 3.9. This used to work in Galactic, but for some reason seems to break in Humble. Trying to figure out what's going on!

wolfv commented 2 years ago

You can find the linking error on our Windows build in Github actions: https://github.com/RoboStack/ros-humble/runs/6868272365?check_suite_focus=true Any ideas? Would be very much appreciated!

wolfv commented 2 years ago

I fixed this by adding this to src/CMakeLists.txt

if (MSVC)
    target_compile_definitions(${PROJECT_NAME}_boost PRIVATE -DBOOST_PYTHON_STATIC_LIB)
endif()

Hello ROS developers! I'm encountering the same error mentioned by @ShivamPR21 when building this package on Windows. I'm using Boost 1.74.0, Python 3.8, and OpenCV 4.1.

How can I resolve this issue?

SENAI-GilmarCorreia commented 1 month ago

I'm not sure how I solved it, but adding the @wolfv part at iron branch and rebooting the PC worked. ¯_(ツ)_/¯
