Hi @ivana,

Manually building ROOT is in general discouraged for regular users, unless justified otherwise. Take a look at more convenient procedure for macOS here.

If you want to continue your build anyways, I would recommend deleting all the *.pcm files in the output
directory in the hope that they get rebuilt, i.e.

$ find /Users/ivana/work/packages/root/root_v6.26.06_build/ -name '*.pcm' -print -delete
$ make


Thank you; I tried your suggestion but I get the same error again. I use to build Root from sources as we need some options that are not set by default.

@Axel, have you seen this before?


There’s a dependency problem somewhere; make -j4 seems to work around this issue :-/ IIRC @vvassilev wanted to have a look?

Thank you !
After removing all *.pcm, make -j4 went till the end and the installation succeeded.
