Compile Ada sources without the shared libraries

Question

How can I compile the Hello World program from here on a glibc environment and run it on a uclibc environment?

localhost:~$ readelf -d /home/localhost/hello | grep NEEDED
0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]

Have a look at dlopen() library set of functions. You'll need to load the libraries from the source file itself. The following code is in C, but you can use Interafaces.C in Ada to interoperate with C libraries:

lib_handle = dlopen("/opt/lib/libctest.so", RTLD_LAZY);
if (!lib_handle) 
{
   fprintf(stderr, "%s\n", dlerror());
   exit(1);
}
