I'm trying to LD_PRELOAD a library that in turn uses ldopen.
this works OK, as long as I don't try to run (with LD_PRELOAD
set) any binaries that use libdl themselves.
Should this be possible? If so, what am I doing wrong?
$ cat libfoo.c
#include <dlfcn.h>
void foo(){
void *handle=handle = dlopen("/lib/libc.so.6", RTLD_LAZY);
dlclose(handle);
}
$ gcc -shared -Wl,-soname,libfoo.so.0 -o libfoo.so.0.0 -fPIC libfoo.c -ldl
$ export LD_PRELOAD=./libfoo.so.0.0
$ bash
bash: can't resolve symbol '_dl_open'
bash: can't resolve symbol '_dl_close'
bash: can't resolve symbol '_dl_catch_error'
$ ls -d .
./
Thanks.
