Subject: setenv and dlopen

Hi all,
I have a problem using dlopen and setting the LD_LIBRARY_PATH with
putenv or setenv.
Here is my test code:
#include <stdio.h>
#include <stdlib.h>
#include <dlfcn.h>
#include <unistd.h>
int main(int argn, char** argv)
{
void* handle;
int ret;
putenv("LD_LIBRARY_PATH=.");
putenv("PATH=.");
handle = dlopen("libmylib.so", RTLD_LAZY);
if (NULL == handle) {
printf("error: %s\n", dlerror());
}
if (2 == argn)
return 0;
ret = execlp("dltest", "dltest", "break", NULL);
if (ret)
perror("Error in starting dltest: ");
return ret;
}
I also tried setenv and absolute path-names for LD_LIBRARY_PATH. Setting
LD_LIBRARY_PATH on the console works perfectly. And as you can see,
setting the PATH variable using putenv is also working for execlp.
Any suggestions?
Henry
