I'll try the following simple code from help dlopen, but failed and got
following information:
: invalid mode for dlopen(): Invalid argument
And the code:
#include <string>
#include <stdio.h>
#include <dlfcn.h>

int main(int argc, char **argv) {
void *handle;
double (*cosine)(double);
char *error;

handle = dlopen (argv[1], RTLD_GLOBAL);
if (!handle) {
fprintf (stderr, "%s\n", dlerror());
exit(1);
}
printf("Got 0x%x from %s.\n", handle, argv[1]);
dlclose(handle);
return 0;
}

Could you help me to check it?
