Hi,
I'm using RTEMS 4.11 and the builtin POSIX API functions to dynamically
load a program image into memory. The program image is loaded in RTEMS
using the following code:
void* handle = dlopen(prog_name, RTLD_NOW | RTLD_GLOBAL);
if (!handle)
printf("dlopen: %s\n", dlerror());
I'm using the GCC built by RTEMS Source Builder to compile the object
located at prog_name in the in-memory filesystem.
What command line should I use to properly compile a single C file to be
loaded this way?
For reference, I've tried the following command line options, but got an
error:
$ /opt/rtems-4.11/bin/sparc-rtems4.11-gcc test.c -c -o test.elf -shared
-fPIC
$ # Run in emulator, result:
$ # dlopen: global symbol not found: _GLOBAL_OFFSET_TABLE_
I have also tried some other combinations and also using the rtems-ld
program. Any ideas?
Thanks,
Boldizsár Palotás
