I believe 'inherit python3targetconfig' may help, as it substitutes most places where native python gets queried by components with target-specific values. Alex Unless I'm mistaken , in the error message we can see that the compiler specified the sysroot correctly (recipe-sysroot and recipe-sysroot-native) recipe-sysroot and NOT recipe-sysroot-native
'--sysroot' is specified correct but that is not automatically add search paths to '-I' directive, if I'm not misreading this: https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html . When you use --sysroot with gcc you have to add = or $SYSROOT to your -I directive in order to add it to search path for headers. With that information I guess '-I =/usr/lib/python3.11' or '-I \$SYSROOT/usr/lib/python3.11' can work but '-I /usr/lib/python3.11' will point to your host.
