Hi ,

IFX 11.50 FC9X6 , AIX 6.1


I'm trying create a simple UDR to get the current 'transaction id' with
less overhead possible...
To use this UDR inside of SPL + Trigger...

I'm not expert on C language, where play with it sometimes...
So , I getting some trouble to compile the .c file, what I not sure if
is some problem with gcc for AIX or the command line used...
I'm stuck on error 'collect2: get_transid.so: cannot open as COFF file'

.... and following the John Miller IIUG/2010 presentation 'The Basics of
Writing and Utilizing C-User Define Routines'...

If anyone have any tips how solve this, I appreciate a lot...

===========================================
$ cat get_transid.c
#include "incl/public/mi.h"
#include "incl/public/milib.h"

mi_integer get_transid(void){
mi_integer transid ;
transid = mi_get_transaction_id() ;
return transid ;
}

$ gcc -g -Wall -fPIC -I/vulca/informix -c get_transid.c
$ l get*
-rw-rw-r-- 1 informix informix 178 Dec 15 14:09 get_transid.c
-rw-rw-r-- 1 informix informix 30140 Dec 16 07:35 get_transid.o

$ gcc -shared -Wl,-soname,get_transid.so -o get_transid.so get_transid.o
collect2: get_transid.so: cannot open as COFF file

$ gcc --version

===========================================

I'm already try some differ approach on "-g" parameter (-gxcoff ,
gxcoff+) without success.


Anyone?
Regards
Cesar

So, it compiled to an object fine.

What happens without the "-W1,..." switch?

Try ld -G to make the .so, something more like:

$ ld -G get_transid.o -o get_transid.so

Not sure what switches AIX requires, I think the machine/release notes say.

"find" ???

That can't be right, find and ld are very different programs.
