Hi, for a Ruby C extension I need to check in extconf.rb the Linux
kernel and glibc version in which the extension is being compiled (so
when running “gem install xxxx”). I need to know this information in
order to use the accept4 system call which exists from kernel 2.6.28
and from glibc 2.10 (both conditions must be satisfied).
So I expect something like the following in my extconf.rb:
if KERNEL_VERSION >= “2.6.28” and GLIBC_VERSION >= “2.10”
Well, I could run “uname -r” but that is dangerous, example:
“2.6.3” >= “2.6.28”
=> true OPSSSSS !!!
And unfortunatelly I cannot add more gems (i.e. versionomy) as
Also, no idea to get the current “glibc” version.
Thanks for any tip.
