afaik, the only way to do this is to use the GOT(global offset table) |
| 13 |
to get the address of global symbols. once you have the address of the |
| 14 |
GOT, you can then load the addresses of your variables from there e.g. |
| 15 |
|
| 16 |
lea eax, [ebx + foo wrt ..gotoff] |
| 17 |
|
| 18 |
to load the address of "foo" into eax. |

this is all nasm speak. you can find more information regarding shared |
| 21 |
libs + asm in section 8 of the wonderful info pages. |
