Subject: for the wiki: a __MUSL__ alternative
Greetings,
Since requests for a __MUSL__ macro still come in every now and then, I
thought it might be useful to add to the wiki the following text at the
end of the section "why is there no __MUSL__ macro?"
If you have a situation that (temporarily) requires that you can
identify the libc being used, consider the following trick: as part of
your configuration script, locate libc.so, then create a symlink from
libc.so to /some/temporary/folder/ldd, and finally execute
/some/temporary/folder/ldd 2>&1 | grep 'musl libc'; Based on the
outcome, you could then add -D__MUSL__ to the relevant environment variable.
I hope that helps,
zg
