If a build expressions has set "enableParallelBuilding = true", then the
generic builder may utilize more than one CPU core to build that particular
expression. This feature works out of the box for GNU Make. Expressions that
use other build drivers like Boost.Jam or SCons have to specify appropriate
flags such as "-j${NIX_BUILD_CORES}" themselves.

/* Fix for NIXPKGS-79: when doing host name lookups, when
|
|
nsswitch.conf contains a line like
|
|
|
|
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
|
|
|
|
don't return an error when mdns4_minimal can't be found. This
|
|
is a bug in Glibc: when a service can't be found, NSS should
|
|
continue to the next service unless "UNAVAIL=return" is set.
|
|
("NOTFOUND=return" refers to the service returning a NOTFOUND
|
|
error, not the service itself not being found.) The reason is
|
|
that the "status" variable (while initialised to UNAVAIL) is
|
|
outside of the loop that iterates over the services, the
|
|
"files" service sets status to NOTFOUND. So when the call to
|
|
find "mdns4_minimal" fails, "status" will still be NOTFOUND,
|
|
and it will return instead of continuing to "dns". Thus, the
|
|
line
|
|
|
|
hosts: mdns4_minimal [NOTFOUND=return] dns mdns4
|
|
|
|
does work because "status" will contain UNAVAIL after the
|
|
failure to find mdns4_minimal. */
