Conflict with boost dependency compiling on Raspberry Pi

[rschuetzler]

I am trying to compile the library on a Raspberry Pi for Python 3.11. When I run the conan install ... command (see command and output below), I get an error of a conflict between boost/[~1.78] and boost/1.83.0 in the graph. I'm familiar with the command line, but not with cmake or conan, so perhaps this is out of my reach to get working. But I would love if somebody could help me resolve these conflicts so I could compile libqi for Python.

I've tried with both qi 4.0.1 as in the README, and 4.0.4, which is as far as I can tell the latest version.

Thanks!

Hello @rschuetzler,

It's an issue I've encountered a few times indeed, and I need to come up with a better solution. Which revision of libqi-python are you trying to build ? On master / qi-python-v3.1.5 at the moment, the conanfile should point to Boost 1.83.

Ah, I think I found the issue. The git clone command in the example has the --branch argument that refers to a nonexistent version-specific branch. So when I cloned the code, it was somehow downloading the code but not the latest version of libqi from the master branch. Correcting that (eliminating the --branch argument) has fixed the dependency conflict.

I'll fix the README for the next release, thank you !
