Hi, in at least root 6.28.4 to 6.30.4 installed with conda python3.9 to python3.11 on my mac m1, running rootcling with any valid arguments afterwards produces
error: invalid integral value '0 -fno-omit-frame-pointer' in '-O0 -fno-omit-frame-pointer'
Thanks for reaching out to the forum! No, that is not a known issue, and I don’t know right away what might be causing it. Could you report the exact rootcling command you are issuing, and the environment variables present while running it?
