[Pdns-users] pdns_recursor stops getting queries on Solaris 10 sparc

[Christian Kuehn]

HI,

we found the same problem and it looks like a problem with Sol10.

Our fix was a small change in sysdeps/SunOS.inc

ifeq ($(CC),cc)
        CC:=gcc
endif

LDFLAGS+=-lresolv -lsocket -lnsl
OS_SPECIFIC_INSTALL=mkdir -p $(DESTDIR)/etc/init.d ; cp pdns-recursor.init.d $(D
ESTDIR)/etc/init.d/pdns-recursor

#OPTIONALS:=optional/portsmplexer.o

#optional/portsmplexer.o: portsmplexer.cc
#       $(CXX) $(CXXFLAGS) -c $< -o $@  ; true


Good luck!

Cheers
Christian
