Hi All......
I have my tool in my one server lets say E1 and same tool I tried to install in E2 server so everything is fine but, while executing the my tool for example...
At that time Im getting this following error.
I tried to use the command
After setting this library path its working fine
Here I'm facing problem now.
If I close the server session . Again I tried to login my server with username and password and If I want to execute this tool (program) again Im getting above error.
So everytime no need to set the Path for library files.
In E1 , It's working fine. But when comes in E2 I'm getting this error.
whenever I want to run that program I should execute the export LD_LIBRARY_PATH command then only I'm able to execute it.
Is it because of again In E2 also we have to compile that program and shall I create the executable file for this program separately?
I'm runtime linking (dlopen and dlsym) to a shared object (library) I've created and after a number of function calls into the library the program core dumps (Illegal operation). This only occurs during runtime linking. If I use the same library and dynamically link during compile time everything... (3 Replies)
I asked the next question in a former thread :
Can I safely share objects that have virtual functions (i.e. have
virtual function table pointers) between two processes ?
Where will the pointers point to in each process ?
The objects are supposed to reside in shared memory

Hi Friends !
I have a library, say libxyz.a.
To view all the object files in the archive, i issued the command :
ar -t libxyz.a
which displayed all the object files it contains.
Now, I would like to know the functions in each object file.
Is there any such command that displays... (3 Replies)
hi all !
Do I need all the shared objects to be present while compiling my code which has reference to a only one shared object, which in turn refers to another shared object.
for example I want to compile example.c which refers to sample.so
sample.so has refrence to anothersample.so
do... (2 Replies)
Hi. Does anyone know by how much a text size of an executable(on ibm) would grow if you link one shared object(library)? Is it a constant number or it depends on a .so that is linked? (3 Replies)
Hi,
i am trying to debug a binary which is using a shared lib.
but i could not succeed in tracking the code flow in the classes defined
in this library.
i get: class MyClass <opaque> error

I have two envoirmets(Envoirment A and Envoirment B) running on same server(AIX vesion 5.3).Both have different groups.I am facing a strange problem.Shared objects of one envoirment (Envoirment A)are getting loaded into the second(Envoirment B).So the servers that have dependency on shared objects...

G'day,
I have been working with a large application that makes extensive use of templates. When compiled under Unix (with g++), this sees some rather impressive bloat. I have been trying to make a temporary quick-fix by using the -frepo option, which results in dramatically smaller shared... (0 Replies)
Hi,
I am looking for references about creating and accessing Shared Objects (.so) through C/C++ on Unix / Linux platforms. Is it possible and where can I find the info.
Thanks

dear Experts,
please help,
actually i am trying to create a .so(shared object through make file through ld)
i am not understaning how to proceed i have tried like
through command like i can do it in 2 step like
my progam :test2.c

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
