cmake question (anxious)

[UselessHua]

How to solve this problem and how to find McCalib?

[rameau-fr]

Thank you very much for trying MC-Calib. Please tell me more about your problem. On what OS are you trying to install the toolbox? Could you give me more details on what led to this error?

[pedroarroyo]

If it helps, I am also seeing this on Ubunty 20.04.

[rameau-fr]

Thank you very much for the additional feedback. Could you please share the entire error message? I will try to replicate it but I assume it is a problem with libraries versions. If possible could you report the version of all your dependencies ? An easy fix is to use the docker provided with MC-Calib (if you are familiar with it).

[vswdigitall]

I can comment line and it works.

@vswdigitall please follow the issue template so we can better understand your setup and resolve the issue faster.

What's on the line CMakeLists.txt:51? I believe CMakeLists.txt has been modified in your case compared to the one found in master branch?

[vswdigitall]

For current master, i can't cmake your code. Only if disable line 74 it works. Line 51 solved by installing doxygen.

Please provide the full output from the cmake command to start with @vswdigitall

I just modified CMakeLists.txt for both of ROOT and 'McCalib' directory like below and run separated build steps;

• Build 'libMcCalib.a'

  cd McCalib
  mkdir build && cd build
  cmake DCMAKE_BUILD_TYPE=Release .. && make -j 8

• Build 'calibrate' and 'create_charuco_boards'

  cd  <ROOT> ## of MC-Calib sources
  mkdir build && cd build
  cmake DCMAKE_BUILD_TYPE=Release .. && make -j 8

Strange things is, libMcCalib.a seems rebuilt during second build step. Anyway it's working in my case.

@nukbridge thank you for providing the solution.
