Hi All again, One more thing that I have tried. If I now do a similar thing as in my previous message with the "funcs.c" file, but this time with the "funcs.cc" file then I can get: ------------------------------------------------------------------------- [root@Treazurac /test]# g++ -I./include -I./backend -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I/usr/include/pgsql -I/usr/include -fpic -c -o funcs.o funcs.cc [root@Treazurac /test]# g++ -shared -o funcs.so funcs.o [root@Treazurac /test]# ls Makefile Makefile.global Makefile.port funcs.cc funcs.o funcs.so* funcs.sql [root@Treazurac /test]# pico -w funcs.sql [root@Treazurac /test]# psql -f funcs.sql -d trdata DROP CREATE [root@Treazurac /test]# psql trdata Welcome to psql, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help on internal slash commands \g or terminate with semicolon to execute query \q to quit trdata=# select concat_text('a','b'); ERROR: Can't find function concat_text in file /test/funcs.so trdata=# -------------------------------------------------------------------------- And although I should not be running as "root", this is a test machine and it is ok for the time being. If I do the same thing as above, but using the "funcs.c" file (which is the exact same file just renamed) --------------------------------------------------------------------------- funcs.c and funcs.cc ------------------------- #include "postgres.h" // for variable length type #include <stdio.h> #include <string.h> #include <stdlib.h> #include <time.h> #include <unistd.h> // for unix crypt function text * concat_text(text *arg1, text *arg2); text * concat_text(text *arg1, text *arg2) { int32 new_text_size = VARSIZE(arg1) + VARSIZE(arg2) - VARHDRSZ; text *new_text = (text *) malloc(new_text_size); memset((void *) new_text, 0, new_text_size); VARSIZE(new_text) = new_text_size; strncpy(VARDATA(new_text), VARDATA(arg1), VARSIZE(arg1)-VARHDRSZ); strncat(VARDATA(new_text), VARDATA(arg2), VARSIZE(arg2)-VARHDRSZ); return (new_text); } -------------------------------------------------------------------------- with funcs.sql ------------------ DROP FUNCTION concat_text(text, text); CREATE FUNCTION concat_text(text, text) RETURNS text AS '/test/funcs.so' LANGUAGE 'c'; ---------------------------------------------------------------------------- With the "funcs.c" file in place I get: ----------------------------------------------------------------------------- [root@Treazurac /test]# gcc -I./include -I./backend -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I/usr/include/pgsql -I/usr/include -fpic -c -o funcs.o funcs.c [root@Treazurac /test]# gcc -shared -o funcs.so funcs.o [root@Treazurac /test]# psql -f funcs.sql -d trdata DROP CREATE [root@Treazurac /test]# psql trdata Welcome to psql, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help on internal slash commands \g or terminate with semicolon to execute query \q to quit trdata=# select concat_text('a','b'); concat_text ------------- ab (1 row) trdata=# ----------------------------------------------------------------------------- so now I do not understand why the "gcc" version works and the "g++" version does not? Just a side note in that I can easliy compile c++ the examples in the interfaces/libpq++ directory without any problems so that this is very strange to me. I really need the "g++" version to work correctly as well? Any ideas anyone? Cheers Lonnie __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!
