I do:
1) gcc -DUNIX -Wall -fPIC -c *.cpp
2) gcc -shared -Wl,-soname,libcrc32.so.1 -o libcrc32.so.1.0
*.o
3) mv libcrc32.so.1.0 /opt/lib

5) ln -sf /opt/lib/libcrc32.so.1.0 /opt/lib/libcrc32.so.1
On SQL:
1) create function DBA.xp_crc32(in p long varchar) returns
unsigned integer external name
'xp_crc32@/opt/lib/libcrc32.so'
2) select DBA.xp_crc32('TestString')

P.S.Listing library attached. ASA 9.0.2. Linux
2.6.18-92.el5.asp121 x86_64.
It's failing to load the library with your function because of an
unresolved reference to an internally-used C++ symbol. (Not very helpful
error message, is it? Takes some work to figure out.) If you can write in C
and not C++ it should work. (Source file needs to be named *.c not *.cpp,
even though using gcc.) If you cannot use plain C, you will have to try to
figure out how to link in the C++ support library it is looking for.
Hope this helps.
