Hello Ondřej, First of all, thank you and everyone at CZ.NIC for the great work you do on Knot. We've been using it for a while now without issues, and recently moved up to version 2 which was mostly painless.
Up until Knot 2.3.2 I've had no trouble compiling on our CentOS 6 build server to distribute via an internal yum repo. When I tried to compile 2.4.0, however, I ran into the following error: make[3]: Entering directory `/home/rpmbuild/rpmbuild/BUILD/knot-2.4.0/src' CC knot/conf/libknotd_la-base.lo In file included from knot/conf/base.c:23: ./knot/nameserver/query_module.h: In function ‘mod_ctr_incr’: ./knot/nameserver/query_module.h:136: warning: implicit declaration of function ‘__atomic_add_fetch’ ./knot/nameserver/query_module.h:136: error: ‘__ATOMIC_RELAXED’ undeclared (first use in this function) ./knot/nameserver/query_module.h:136: error: (Each undeclared identifier is reported only once ./knot/nameserver/query_module.h:136: error: for each function it appears in.) ./knot/nameserver/query_module.h: In function ‘mod_ctr_decr’: ./knot/nameserver/query_module.h:144: warning: implicit declaration of function ‘__atomic_sub_fetch’ ./knot/nameserver/query_module.h:144: error: ‘__ATOMIC_RELAXED’ undeclared (first use in this function) ./knot/nameserver/query_module.h: In function ‘mod_ctrs_incr’: ./knot/nameserver/query_module.h:154: error: ‘__ATOMIC_RELAXED’ undeclared (first use in this function) ./knot/nameserver/query_module.h: In function ‘mod_ctrs_decr’: ./knot/nameserver/query_module.h:167: error: ‘__ATOMIC_RELAXED’ undeclared (first use in this function) As far as I can tell, and please correct me if I'm wrong, this is due to using an outdated version of GCC (4.4.7), which is the latest available on the epel repository for CentOS 6. We saw no issues building on our CentOS 7 build machine, where a more recent version of GCC is available from the epel repo. Is this expected? Thanks, best regards. - Gonzalo On 18/01/17 12:54, Ondřej Surý wrote: > Dear Knot DNS users, > > CZ.NIC is proud to release the 2.4.0 release of Knot DNS.
