 Reporter:  dazuelos               |      Owner:  (none)
     Type:  defect                 |     Status:  new
 Priority:  Normal                 |  Milestone:
Component:  ports                  |    Version:  2.9.3
 Keywords:  undeclared identifier  |       Port:  libfido2
-----------------------------------+----------------------
 I am running macOS 10.10.5 + Xcode 7.2 + Command Line Tools 7.2.

 After a:
 {{{
 port -d selfupdate
 port -c -u upgrade outdated
 }}}
 which exited on error on libfido2, I ran:
 {{{
 port -c -u clean libfido2
 port -c -u install fido2
 }}}
 I got an error during the build phase.
 Looking at the log file, I went to the problem directory manually:
 {{{
 cd
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_security_libfido2/libfido2/work/build
 }}}
 and ran manually the mono-threaded make:
 {{{
 make -j1 -w all VERBOSE=ON
 }}}

 Which produced the following tail of log:
 {{{

 This look like very similar to ticket:
 {{{
 #68333 assigned defect
 }}}

 I don't need libfido2 since I don't use Yubikey,
 but this library seems to be required by a lot of security tools I am
 using.
 ( squid3, postfix servers in production env. from MacPorts + research
 firewall based on PF + zsh + Perl ).

 How may I help to further analyze this problem?
