Do you have the "PC-relative const data" switch turned on? If not, you can even use const data in your shared library. Even with that switch, you can't define constant data in a shared library that references other constant items, since shared libraries don't have data segments and no relocations are performed upon them. Where does the pointer in the first item point? It points to data_one. However, that computation can only be performed at runtime, and since the data is stored directly in the code, it cannot be modified. You need to rework your data structures to not have embedded pointers if you want to do this. You also could add your "const_one" to the library's global structure, then set it up at library open time. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
