Assistance with Installing vision_visp in ROS Humble

[m11112089]

Hello,

Here are the steps to address some common installation challenges with the vision_visp package:

1. Install camera-calibration-parsers

$ sudo apt install ros-humble-camera-calibration-parsers

2. Install image_proc

$ sudo apt install ros-humble-image-proc

3. Install rosbags

$ pip install rosbags

if Python's pip is not installed.

$ sudo apt install python3-pip

If rosbags-convert is still not found, add the local bin directory to your PATH:

$ export PATH=$PATH:~/.local/bin

4. 'rosbags parameter error'

$ pip install rosbags==0.9.22

If you're experiencing parameter errors with rosbags, it might be due to updates in the package. Here are the relevant versions:

• Newest version: rosbags 0.10.0 (Released on April 12, 2024)
• Previous version: rosbags 0.9.22 (Released on March 6, 2024)

5. ViSP Version Changes
   The vpMeSite class has undergone changes in member variables from ViSP 3.5.0 to ViSP 3.6.0:

   • ifloat -> m_ifloat
   • jfloat -> m_jfloat

   If you have downloaded ViSP 3.6.0, please update your code from ifloat to m_ifloat and from jfloat to m_jfloat. Alternatively, you can try the pre-fixed version from my repository:

   $ cd your/workspace/src
   $ git clone https://github.com/m11112089/vision_visp.git -b fix_build_bug

@fspindle, given the recent challenges faced by some users, including myself, I wonder if it might be possible to review and potentially update the parameters for rosbags and refine the README.md to enhance clarity and ease of installation. I understand these changes might require some time and effort, and I'm more than willing to assist or even handle the updates through a PR if that would be helpful.

Hello @m11112089 ,
I find your summary very useful, however I have encountered another issue when trying to build vision_visp.
Could you please take a look at it, what might be causing the problem?
