Обсуждение: More SCO funnies

Ok so thanks to Larry I managed to get postgresql compiled and running
on SCO. Now I'm trying to compile a small 'C' program. When I link I get

cc -L/usr/local/pgsql/lib -lpq -lm -o t_postgresql t_postgresql.o
post_util.o
undefined                       first referenced
  symbol                             in file
PQexec                              t_postgresql.o
PQclear                             t_postgresql.o
PQfinish                            t_postgresql.o
PQresultStatus                      t_postgresql.o
PQcmdTuples                         t_postgresql.o
PQntuples                           t_postgresql.o
PQgetvalue                          t_postgresql.o
PQftype                             t_postgresql.o
PQfmod                              t_postgresql.o
PQnfields                           t_postgresql.o
PQfname                             t_postgresql.o
PQsetdbLogin                        t_postgresql.o
PQstatus                            t_postgresql.o
floor                               post_util.o
i386ld fatal: Symbol referencing errors. No output written to t_postgresql

Larry, can you work your magic again?

This looks like a problem on your end, post_util.o references 'floor'
and even with -lm it's not being found.  Can you compile something
with post_util.o without t_postgresql.o to see if it's you or us? :)

put the -lpq -lm AFTER the .o file

NP.

It's generally a good idea to specify libraries after the object
files.  Most "REAL" Unix ld's go in order.

Well I guess sco and linux are a bit different. Also had to add -lsocket
to the end and presto!
