[PRO*C] Compiler sous Windows

Bonjour,
Je suis en train de développer une application en proc*c la précompilation en fichier codé en c se passe bien mais j'ai du mal a compiler ce fichier.c pour obtenir l'exécutable
y'aurait-il un compilateur c en particulier à utiliser avec le pro*c??

Tout compilo C90 fera l'affaire quelque soit la plateforme !

Quels sont les problèmes ?

Tu ne donne aucune infos...

Bonjour,
Merci Vicenzo pour ta réponse, alors je vous explique la situation:
j'essaie de faire un petit pgm en pro*c qui fait une selection d'un champ dans une table donnée, la pré-compilation sous pro*c se passe sans pb mais lorsque je veux compiler le source c j'obtiens les erreurs suivantes:

C:\DOCUME~1\fadil\LOCALS~1\Temp/ccEXb2wV.o:test.c:(.text+0xce): undefined reference to `ECPGget_sqlca'
C:\DOCUME~1\fadil\LOCALS~1\Temp/ccEXb2wV.o:test.c:(.text+0x29d): undefined reference to `sqlcxt'
C:\DOCUME~1\fadil\LOCALS~1\Temp/ccEXb2wV.o:test.c:(.text+0x2fb): undefined reference to `ECPGget_sqlca'
C:\DOCUME~1\fadil\LOCALS~1\Temp/ccEXb2wV.o:test.c:(.text+0x41c): undefined reference to `sqlcxt'

les outils utilisés: Mingw en tant que compilateur et emacs en tant qu'éditeur
O.S: Windows XP

salut,

ce n'est pas une erreur de compilation mais une erreur de linkage...

Il faut indiquer à ton linker la librairie pro*c : orasqlX.lib ou X est la version de Oracle.

J'ai effectivement inséré les paths des librairies nécessaires c'est à dire orasql9.lib, orasqx9.lib et oci.lib mais sans résultat j'ai tjrs le même pb. Je vous envoie la ligne de commande gcc:

gcc -L,I:\oracle\ora92\precomp\lib\msvc\orasql9.lib,I:\oracle\ora92\precomp\lib\msvc\orasqx9.lib,I:\oracle\ora92\oci\lib\msvc\oci.lib test.c

j'ai cherché partout sur le net mais la majorité des forums traitent ce pb par rapport à unix où il faut juste linker vers libclntsh.so
Mais quand il s'agit de windows les forums n'apportent pas de réponse

tu n'as pas besoin de passer orasqx9.lib et oci.lib...

Seul orasql9.lib est nécessaire..

parce que tu utilise gcc, tu devrais faire la chose suivante :

- dans le répertoire I:\oracle\ora92\precomp\lib\msvc, fais une copie de orasql9.lib que tu nommes liborasql9.lib

- et ensuite utilises la ligne de commande suivante :

Code:

---

gcc -L"I:\oracle\ora92\precomp\lib\msvc" -lorasql9 test.c

---

et ca devrait le faire...

ça ne marche toujours pas,
je recois tjrs le meme message:

C:\DOCUME~1\fadil\LOCALS~1\Temp/ccMcAdGa.o:test.c:(.text+0xce): undefined reference to `ECPGget_sqlca'
C:\DOCUME~1\fadil\LOCALS~1\Temp/ccMcAdGa.o:test.c:(.text+0x29d): undefined reference to `sqlcxt'
C:\DOCUME~1\fadil\LOCALS~1\Temp/ccMcAdGa.o:test.c:(.text+0x2fb): undefined reference to `ECPGget_sqlca'
C:\DOCUME~1\fadil\LOCALS~1\Temp/ccMcAdGa.o:test.c:(.text+0x41c): undefined reference to `sqlcxt'

Est ce que l'utilisation de la librairie ocilib pourrait résoudre le pb??

Pour pro*c, cela reste un souci de config de projet... si tu pouvait poster ou m'envoyer ton projet par mail, je pourrais essayer de voir...

Sinon, tu peux toujours essayer ocilib qui est plus riche de pro*c. 8-)

De plus, tes exe ne seront pas dépendant de la version d'oracle et le code applicatif beaucoup plus simple à écrire et débugger !

ps : ocilib fonctionne très avec mingw...

Je vous envoie mon code tt de suite

Bon, j'ai testé et le souci vient de ta précompilation !!

postes le fichier de config ou les options que tu as passé à pro*c pour générer ton fichier....

alors je vous explique j'ai écrit le code pro*c sous un éditeur fourni par oracle qui s'appelle proC-C++ donc je n'ai pas de commandes précises je ne fais que cliquer sur précompiler et j'obtiens mon source en c
Pourriez vous m'indiquer la démarche à suivre svp?

pourriez vous me donner des renseignements sur la nature du problème vous avez dit qu'il s'agissait d'une erreur de précompilation mais je n'arrive pas a comprendre
svp aidez moi c'est extrêmement urgent

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

---

commence par remplacer

Code:

---

1 2 3 4

#include <sqlca.h> #include <stdlib.h> #include <sqlda.h> #include <sqlcpr.h>

---

par

Code:

---

1 2 3

#include <oraca.h> #include <sqlca.h> #include <stdlib.h>

---

ensuite, retire les lignes suivantes :

Code:

---

1 2	EXEC SQL INCLUDE ORACA; EXEC SQL INCLUDE SQLCA.H;

---

enfin, recompiles le source pro*c et recompiles le source c

tjrs la même erreur

Code:

---

undefined reference to `sqlcxt'

---

au fait il y'a une ligne qui pose pb

Code:

---

sqlcxt((void **)0, &sqlctx, &sqlstm, &sqlfpn);

---

c'est à cause de cette ligne qu'il affiche le message d'erreur

Code:

---

undefined reference to `sqlcxt'

---

et si tu fais plutôt :

Code:

---

1 2	gcc -I"I:\oracle\ora92\precomp\public" -c test.c -o test.o gcc -L"I:\oracle\ora92\precomp\lib\msvc" -lorasql9 -o test.o

---

t'as quoi comme output ?

je dois executer une des directives ou toutes les deux?

les deux dans l'ordre....

alors lorsque j'exécute la première ligne de commande la compilation se fait sans erreurs, mais lorsque j'execute la deuxième j'obtiens l'erreur suivante

Code:

---

undefined reference to `_WinMain@16'

---

Bonjour,
JE n'arrive pas à trouver l'origine du problème j'ai cherché un peu partout et j'ai trouvé qu'il fallat replacer:

Code:

---

int main()

---

par:

Code:

---

int APIENTRY WinMain( HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)

---

Mais le problème persiste quand même y'aurait-il une librairie que je devrais linker dans la deuxième ligne de commande gcc?

j'ai exécuté la ligne de commande suivante mais mon exécutable ne s'exécute pas

Code:

---

gcc -I"I:\oracle\ora92\precomp\public" -L"I:\oracle\ora92\precomp\lib\msvc" -lorasql9 -c test.c -o test.exe -mwindows

---

lorsque j'éxécute test.exe j'obtiens le message d'erreur suivant:

Code:

---

1 2	C:\dev\test.exe Le processeur NTVDM a rencontré une instruction non autorisée.

---

je me demande si c'est du à l'option -c qui ne fait pas l'édition des liens lorsque je l'enlève je retombe sur l'erreur que j'avais au début

Code:

---

undefined reference to `_sqlcxt'

---

j'ai recompilé avec les deux lignes de commande en même temps c'est à dire

Code:

---

1 2	gcc -I"I:\oracle\ora92\precomp\public" test.c -o test.o gcc -L"I:\oracle\ora92\precomp\lib\msvc" -lorasql9 -o test.exe

---

je n'obtiens pas d'erreur lors de la compilation mais mon exécutable ne retourne aucun résultat
