May 12, 2003 Another link question: how to allow re-definitions? | ||||
---|---|---|---|---|
| ||||
Can optlink allow linking a working executable, when modules have conflicting definitions -- symbols having the same name but associated with non-identical code, resolved by e.g. some "first/last wins" logic, like some other linkers do? (Remember "poor man's polymorphism", e.g. for overriding default callback functions provided by a library...) Cheers, Lunatic Sz. |

I'm sorry, it does not. I don't know of any linker that has that. > (Remember "poor man's polymorphism", e.g. for overriding default callback functions provided by a library...) You must be thinking of how libraries are searched for unresolved symbols, in order. That works. |

I don't know of any linker that has that. LCCLNK was the last one I used this way. See below, please. > > (Remember "poor man's polymorphism", e.g. for overriding default callback functions provided by a library...) > > You must be thinking of how libraries are searched for unresolved symbols, in order. That works. Yes, that's part of the game. The question is how the duplicate definitions can be resolved in a scenario like this: FRAMEWORK.LIB: _main _callback_one ; default implementation _callback_two ; default implementation ... MYAPP.OBJ: _callback_one ; custom implementation So, how to correclty link this stuff with OPTLINK? link myapp.obj, myapp.exe,, framework.lib, app.def, app.res does not seem to be enough. I used to manage with the few compiler systems I tried, but that was some 5 years ago. But I know LCC works, for sure, as just tried it again: lcclnk -subsystem windows -o test.exe test.obj winmill.lib test.res Of course, I get warnings: def_app.obj: multiple definition of _wm_configure first definition is in file test.obj def_app.obj: multiple definition of _wm_pre_loop first definition is in file test.obj def_app.obj: multiple definition of _wm_post_loop first definition is in file test.obj Time: 8.982 seconds But the executable is created perfectly OK. Thanks, Sz. |

So, the EXE is there. But it does not run: (see the attached box). Now, is it possible that OPTLINK has already been doing it for me, I just screw up the EXE type somehow? Or is this failure indeed due to an incomplete link? Thanks, Sz. begin 666 err.gif .dat M1TE&.#EA@P*F`+,```4#!=V.@P<9D=Y3,'=M9+H&!^'.P],S'P1<[C.4_ 0.
