Install problem with 'mapnik::proj_transform'

[JBacc1]

Install of python-mapnik failed with errors citing 'mapnik::proj_transform' at: sudo python3 setup.py install

I'm no linux specialist, but last command run was:

Don't know if more info is needed, but I'm in a dead end.

looks like you are using mapnik@master to build python-mapnik.

mapnik@master have been updated to support proj >7.2.0 and therefore had some breaking changes.

You would need to change all occurences of << "from " << t.dest().params() << " to: " << t.source().params() to << proj_transform_->definition()

Or pull the proj6 branch in.

Hello,
Thanks for your answer. I changed the mapnik_proj_transform.cpp as you adviced, but the errors are still there. Are there other files to check as well?
Or I'll have to dig deeper and find how to get the proj6 be used. Or wait for the mapnik and python-mapnik to be compatible.
Thanks,
JB.

[mathisloge]

you need to use the correct variables. ca66af6 and feec9af are looking like the necessary changes you would need to apply. But you can also just merge proj6 branch into your local master branch.

[braandl]

looks like you are using mapnik@master to build python-mapnik.

mapnik@master have been updated to support proj >7.2.0 and therefore had some breaking changes.

I do get the same error with proj@9.2.1 and any other version I tried. Any ideas?
