| Imam .LIB fajl pisan za C pod dosom i heder fajl sa deklaracijama funkcija.(lepo radi sa Turbo C-om) Zanima me kako i da li mogu da koristim ovu biblioteku (tj. njene funkcije) u Turbo C++ 3.0? (pokusao sam da uradim kao i u Turbo C-u ali on prijavljuje Linker Error) Da li postoji način da nekako prepravim ovu biblioteku tako da radi pod Windowsom? (ova biblioteka sadrži funkcije za komunikaciju sa hp-ib karticom) Da li neko može da objasni kako se zapravo linkkuje .LIB fajl.
Kako mogu da disasemblujem ovu biblioteku tj. da vidim kod svake funkcije? Da li se format .LIB fajla razlikuje ako je pravljen recimo iz C-a i iz Pascala?

LIB fajl je kolekcija .obj fajlova koji se dobijaju kompajliranjem koda.
Dakle, on sadrzi masinski kod za odredjen procesor i OS, sa referencama ka nekim drugim funkcijama koje se u linkeru razresavaju.
Formati obj fajlova su obicno OMF ili COFF - i tesko da mozes nesto za DOS da linkujes sa Win32 linkerom. Najpametnije bi bilo da kontaktiras autore biblioteke i da ih zamolis da ti dostave verziju za tvoj OS i kompajler.
Drugo resenje, ako nemas nista pametnije, je da uzmes Watcom C kompajler, on je imao neku alatku za disasembliranje OBJ i LIB fajlova ako se dobro secam - i da pokusas to nekako da asembliras sa MASM-om, ali ovo je vrlo tezak posao jer je kod verovatno 16-bitni i koristi CRT funkcije tog starog kompajlera pa ce posao konverzije biti previse naporan da bi se stvarno isplatio.

Dobro. Ali kako da koristim funkcije ove bibiliteke u turbo c++ 3.0 pod dosom?
Nije mi jasno zasto radi u Turbo C, a u C++ javlja gresku?

Mozes li nam makar dati te "linker error" poruke - pa da pokusamo da ustanovimo gde je greska...
[ kajla @ 20.12.2003. 17:35 ] @
Dobijem poruku tipa: "Undefined symbol IOTIMEOUT(long,double) in module MERENJE.CPP" gde je IOTIMEOUT funkcija iz .LIB fajla. I još nešto kad napišem funkciju:
Code:
int zbir(a,b)
int a,b
{
return a+b;
}
Dobijem Linker error sa istom porukom samo za funkciju zbir. Onaj ko je pisao .LIB fajl svoje funkcije je deklarisao kao gore. Predpostavljam da je ovo razlog zašto ovo biblioteka radi u Turbo C-u a neredi u Turbo C++ 3.0. Kako da ovo rešim?
poz [ sspasic @ 20.12.2003. 20:51 ] @
A da nije u pitanju razlika izmedju toga kako C i C++ ime funkcije pretvaraju u simbol za linker? C++ ugradjuje i tip parametara a C ne.
Promeni ekstenziju fajla u C ili ovaj zbir (moze i include) uokviri sa:
Code:
extern "C" {
... // ovde ubaci deklaraciju funkcije zbir i include
};
Mozda ovo pomogne. Pod uslovom da taj LIB uopste moze da se koristi sa TC++ 3.0. [ kajla @ 21.12.2003. 10:52 ] @
Heder falj sam izmenio da izgleda ovako:
Code:
extern "C"
{
int far IOABORT(long);
int far IOCLEAR(long);
int far IOCONTROL(long, int, int);
int far IODMA(long, int, int);
int far IOENTER(long, float far *);
int far IOENTERA(long, float far *, int far *);
int far IOENTERAB(long, void far *, int far *, int);
int far IOENTERB(long, void far *, int far *, int);
int far IOENTERS(long, char far *, int far *);
int far IOEOI(long, int);
int far IOEOL(long, char far *, int);
int far IOFASTOUT(long, int);
int far IOGETTERM(long, int far *);
int far IOLLOCKOUT(long);
int far IOLOCAL(long);
int far IOMATCH(long, char, int);
int far IOOUTPUT(long, double);
int far IOOUTPUTA(long, float far *, int);
int far IOOUTPUTAB(long, void far *, int, int);
int far IOOUTPUTB(long, void far *, int, int);
int far IOOUTPUTS(long, char far *, int);
int far IOPPOLL(long, int far *);
int far IOPPOLLC(long, int);
int far IOPPOLLU(long);
int far IOREMOTE(long);
int far IORESET(long);
int far IOSEND(long, char far *, int);
int far IOSPOLL(long, int far *);
int far IOSTATUS(long, int, int far *);
int far IOTIMEOUT(long, double);
int far IOTRIGGER(long);
}
Sada dobijam ovakvu grešku:
Linker Error: Fixup overflow at _TEXT:011F, target = _IOLOCAL in module MERENJE.CPP
Može li neko objasniti zašto javlja ovu grešku?

Ova biblioteka ne koristi CRT funkcije jer ništa ne ispisuje, već ima funkcije za komunikaciju sa hpib karticom. Koristio sam program obj2asm da disasemblujem ovaj .lib fajl i dobio sam sledeće:

HPIB_TEXT ENDS
END
Nije mi jasno gde se nalaze funkcije HPIBLIB_SEND, i druge. Drugo što mi nije jasno kako ova biblioteka radi bez fajla mclarge.ASM? Da li neko može da objasni šta je u pitanju?

Predpostavljam da ovaj progy nije dobro preveo ovaj .LIB fajl pa me zanima da li postoji još neki progy koji radi ovo. Neko je spomenuo Watcom C compiler ali ja na netu nigde nisam uspeo da nađem link koji radi, pa ako neko zna gde se ovo može naći nek postuje preko foruma.
Drugo što me zanima je kako da debugujem program koji koristi ovu biblioteku i da na taj način vidim kako rade funkcije ove biblioteke.(Ja treba svega dve funkcije iz ove biblioteke da prebacim da rade pod Windowsom) Probao sam sa Turbo Debuggerom za DOS ali nikako nemogu da nadjem gde se pozivaju ove funkcije. Ima li neko ideju za ovo?
