Every time I run conan init
in a fresh docker container, I get the following warning:
************************* WARNING: GCC OLD ABI COMPATIBILITY ***********************
Conan detected a GCC version > 5 but has adjusted the 'compiler.libcxx' setting to
'libstdc++' for backwards compatibility.
Your compiler is likely using the new CXX11 ABI by default (libstdc++11).
If you want Conan to use the new ABI for the default profile, run:
$ conan profile update settings.compiler.libcxx=libstdc++11 default
Or edit '/home/smith/.conan/profiles/default' and set compiler.libcxx=libstdc++11
************************************************************************************
It's annoying, and distracting. Redundant, too, since the very next command I run in the script is the one for setting the ABI, as suggested in the warning.
conan profile update settings.compiler.libcxx=libstdc++11 default
Is there a way to disable the warning, to avoid seeing it?
This warning can be skipped when CONAN_V2_MODE
is on: e.g.:
conan:~$ export CONAN_V2_MODE=1
conan:~$ conan config init
WARN: Remotes registry file missing, creating default one in /home/conan/.conan/remotes.json

*** You can change them in /home/conan/.conan/profiles/default ***
*** Or override with -s compiler='other' -s ...s***
But that variable also activates some other conan v2 options. You can read more here: https://docs.conan.io/en/latest/reference/conan_v2_mode.html
