Shared Object library problem
Hi,

When using shared objects on AIX 4.3 i am getting runtime problems.
I have a small sample program which links to a shared object libray, oracle and system related libraries.
At runtime it fails (gives segmentation fault and coredump ) in one proc file when executing login statement.

But the same program instead of using shared object library if i use archives and static linking runs fine.
What could go wrong? Any environment variable problem?
my LIBPATH variable points = "$ORACLE_HOME/lib32:$ORACLE_HOME/lib" and at linking phase i use "-L$(ORACLE_HOME)/lib32 -lc -lnsl -L$(ORACLE_HOME)/lib -lclntsh $(ORACLE_HOME)
/lib/libsql9.a -lnsl -ldl -lC -lm" arguments.

Debugging shows failure occurs when
"sqlcxt((void **)0, &sqlctx, &sqlstm, &sqlfpn);" is executed.
Which follows

Illegal instruction (reserved addressing fault) in . at 0x0 ($t1)
0x00000000 00000000 Invalid opcode.
I have urgent requirement of developing my application. Smilie
Any help is appreciated.

Thanks

dylibprof

DYLIBPROF(1)						      General Commands Manual						      DYLIBPROF(1)

NAME

       dylibprof - control the shared pc sampling of a dynamic shared library

SYNOPSIS

       dylibprof [-e | -d] | [-c | -r | -b | -h | -p [-o <file>] <dylib>]

DESCRIPTION

       Dylibprof  along  with  the server /usr/libexec/profileServer allows shared program counter sampling of a dynamic shared library across all
       the programs that use the library.

       To use dylibprof(1), /usr/libexec/profileServer must be running.  So first start /usr/libexec/profileServer and leave  it  running  in  the
       back ground:
	    % /usr/libexec/profileServer >& /dev/console &

       /usr/libexec/profileServer starts up with shared pc sampling disabled.  It should not be left running with shared pc sampling enabled if no
       sampling is being done as every launch of a program that uses the dynamic linker is effected.  This is true even to a small extent if there
       no libraries being sampled.

       If you need to profile from boot up for all processes then the following line can be added to /etc/bootstrap.conf:
	    server "/usr/libexec/profileServer" services NSProfileServer NSProfileControl;

       Before any dynamic shared library can be sampled sampling must be enabled as
       follows:
	    % dylibprof -e

       It can then later be disabled when no more sampling is to be done with:
	    % dylibprof -d

EXAMPLE

       To  sample  the	dynamic  shared  library  /System/Library/Frameworks/System.framework/Versions/B/System for example requires the following
       steps.  First create a sample buffer for the library:
	    % dylibprof -c /System/Library/Frameworks/System.framework/Versions/B/System

       Then begin the sampling:
	    % dylibprof -b /System/Library/Frameworks/System.framework/Versions/B/System
       After this programs launched using this library will be part of the shared pc sampling.	Typically what would be done is to  then  use  the
       system normally for a number of hours.

       Then to halt the sampling:
	    % dylibprof -h /System/Library/Frameworks/System.framework/Versions/B/System

       The profiling output file (a gmon.out file) can be created with:
	    % dylibprof -p -o /tmp/gmon.out /System/Library/Frameworks/System.framework/Versions/B/System

       Using the profiling output file and the library a profile listing and a time based order file (time.order) can be created with: gprof(1):
	    % gprof -S /System/Library/Frameworks/System.framework/Versions/B/System /tmp/gmon.out

       When no more sampling for this library is to be done the sample buffer can be
       removed with:
	    % dylibprof -r /System/Library/Frameworks/System.framework/Versions/B/System

       The options are:

       -e     Enable shared program counter sampling for dynamic libraries.

       -d     Disable shared program counter sampling for dynamic libraries.

       -c     Create a pc sample buffer for the library.

       -b     Begin sampling for programs subsequently launched using the library.

       -h     Halt sampling for programs subsequently launched using the library.

       -p     Produce a profiling output file (a gmon.out file) for the library.

       -r     Remove the pc sample buffer for the library.

       -o name
	      Use the file name instead of gmon.out when producing the profiling output file with the -p above.

FILES

       gmon.out 		 profile output file
       /var/tmp/profile/profile.XXXXXX the sample buffer file
