We are trying to install Postgres replication using pgReplicator. We are following the installation instruction according to http://pgreplicator.sourceforge.net/installation.html The problem is with running pgrd daemon. There is no errors when we compile TCL-DP but when we run pgrd we have the following errors: [replicator@demofbo bin]$ ./pgrd couldn't load file "/usr/lib/tcl8.3/dp4.0/unix/libdp40.so": /usr/lib/tcl8.3/dp4.0/unix/libdp40.so: undefined symbol: TclHasSockets while executing "load /usr/lib/tcl8.3/dp4.0/unix/libdp40.so" ("uplevel" body line 1) invoked from within "uplevel #0 load [list $dir/unix/libdp40.so]" (procedure "LoadLib" line 5) invoked from within "LoadLib /usr/lib/tcl8.3/dp4.0" ("package ifneeded" script) invoked from within "package require dp" (file "./pgrd" line 5) We have already modified dpInit.c file as it has been suggested http://pgreplicator.sourceforge.net/faq.html but it did not help. Is anybody has experienced with that kind of problem?
