compile error while using dlopen
Hi unix lovers,
I am getting error while compile a function which uses dlopen.
My code is
Quote:
$ cat testjvm.c
#include<stdio.h>
#include <dlfcn.h>
#include <link.h>
void main()
{
int retval=0;
retval = (int)dlopen("libjvm.so",RTLD_LAZY);
if(retval == 0)
printf("\nFailed to load JVM Library");
else
printf("\nSuccessfully loaded JVM Library");
}
I am getting error as follows
Quote:
$ cc testjvm.c
Undefined first referenced
symbol in file
dlopen testjvm1.o (symbol belongs to implicit dependency /usr/lib/libdl.so.1)
ld: fatal: Symbol referencing errors. No output written to a.out
$
Am I missing something? I think I am missing a lot :-)
I am using solaris.
Thanks in advance,
-Ashish

papi_is_initialized
PAPI_is_initialized(3) PAPI PAPI_is_initialized(3)
NAME
PAPI_is_initialized -
check for initialization
SYNOPSIS
Detailed Description
@retval PAPI_NOT_INITED
Library has not been initialized
@retval PAPI_LOW_LEVEL_INITED
Low level has called library init
@retval PAPI_HIGH_LEVEL_INITED
High level has called library init
@retval PAPI_THREAD_LEVEL_INITED
Threads have been inited
@param version
upon initialization, PAPI checks the argument against the internal value of PAPI_VER_CURRENT when the library was compiled.
This guards against portability problems when updating the PAPI shared libraries on your system.
@par Examples:
int retval;
retval = PAPI_library_init(PAPI_VER_CURRENT);
if (retval != PAPI_VER_CURRENT && retval > 0) {
fprintf(stderr,"PAPI library version mismatch!
");
exit(1); }
if (retval < 0)
handle_error(retval);
retval = PAPI_is_initialized();
if (retval != PAPI_LOW_LEVEL_INITED)
handle_error(retval);
*
PAPI_is_initialized() returns the status of the PAPI library. The PAPI library can be in one of four states, as described under RETURN
VALUES.
