setenv and dlopen

[Henry Margies <henry.margies@gmx.de>]

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
