Oh, here I was thinking you were 3 steps ahead of me. :-) Per "perldoc ExtUtils::Embed", ccopts() = perl_inc() plus ccflags() plus ccdlflags(). On my system: [rhaas pgsql]$ perl -MExtUtils::Embed -e 'for (qw(ccopts ccflags ccdlflags perl_inc)) { print "==$_==\n"; eval "$_()"; print "\n\n"; };' ==ccopts== -fno-common -DPERL_DARWIN -mmacosx-version-min=10.12 -pipe -Os -fno-strict-aliasing -fstack-protector-strong -I/opt/local/include -DPERL_USE_SAFE_PUTENV -I/opt/local/lib/perl5/5.24/darwin-thread-multi-2level/CORE ==ccflags== -fno-common -DPERL_DARWIN -mmacosx-version-min=10.12 -pipe -Os -fno-strict-aliasing -fstack-protector-strong -I/opt/local/include -DPERL_USE_SAFE_PUTENV ==ccdlflags== ==perl_inc== -I/opt/local/lib/perl5/5.24/darwin-thread-multi-2level/CORE I don't have a clear sense of whether ccopts() or ccflags() is what we want here, but FWIW ccopts() is more inclusive. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
