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.ocollect2: get_transid.so: cannot open as COFF file $ gcc --version gcc (GCC) 4.2.0Copyright (C) 2007 Free Software Foundation, Inc.

Anyone? Regards Cesar

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. > > $ gcc --version > gcc (GCC) 4.2.0> Copyright (C) 2007 Free Software Foundation, Inc. > This is free software; see the source for copying conditions.

That can't be right, find and ld are very different programs. > > =========================================== > > I'm already try some differ approach on "-g" parameter (-gxcoff , > gxcoff+) without success. > > > Anyone? > Regards > Cesar ----- No virus found in this message.
