error on local build about kcap HOT 2 OPEN

Hello @ClaudioNahmad

The fastest solution might be for you to move to CosmoSIS v3 as this now has most of the functionality of KCAP and is well maintained. We recently worked with Joe Zuntz to include COSEBIs in the latest version. It doesn't have Montepython as far as I know, but it does have polychord, multinest and nautilus which are all good alternatives.

Have a look at https://github.com/joezuntz/cosmosis-standard-library/blob/main/examples/des-y3_and_kids-1000.ini

which runs the recent DES+KiDS joint cosmic shear analysis

cosmosis examples/des-y3_and_kids-1000.ini runtime.sampler='polychord'

And incase you're new to CosmoSIS to, here are the installation instructions:
https://cosmosis.readthedocs.io/en/latest/intro/installation.html

from kcap.

make[1]: g++: Command not found suggests you're missing the compiler.

As Catherine said, I'd suggest using the latest cosmosis installation. We're also working on a python-only implementation of the relevant modules, to circumvent these kind of compilation issues in the future.
