Hi,
Im writing a function in C (encode) for PG that uses blowfish encryption
here is how I compile it.
gcc -I/usr/src/postgresql-7.0.3/src/include
-I/usr/src/postgresql-7.0.3/src/backend -O2 -Wall -Wmissing-prototypes
-Wmissing-declarations -lcrypt
-I/usr/src/postgresql-7.0.3/src/interfaces/libpq
-I/usr/src/postgresql-7.0.3/src/include -fpic
-I/home/boulat/Funio.com/database/libblowfish.a -c -o encode.o
encode.c
it compiles nicely with 0 error or warnings,
then i do
gcc -shared -o encode.so encode.o
rm encode.o
so now im left we a ready to go encode.so , So now I add that function
to DB
testdb=# CREATE FUNCTION encode(text,text)
testdb-# RETURNS text
testdb-# AS '/home/boulat/Funio.com/database/encode.so'
testdb-# LANGUAGE 'C';
CREATE
no problems there either, BUT ...
testdb=# select encode('bob','bob');
ERROR: Load of file /home/boulat/Funio.com/database/encode.so failed:
/home/boulat/Funio.com/database/encode.so: undefined symbol:
BF_cfb64_encrypt
thats the function that I call from inside my c code...
but Why??? It compiled with no errors or warning, and I have all the
right includes in my source code.
Im confused!
Any help would be appreciated.
Regards,
Boulat Khakimov
