fichiers systeme UNIx et Linux

Bonjour a tous
Je suis en train de porter un code Unix (Solaris 8) vers du Linux (RedHat 5). A la compilation, certaines erreurs apparaissent et notamment une qui me laisse pantois !
Voici l'erreur :

Code:

---

../src/tli.c:433: error: invalid application of ‘sizeof’ to incomplete type ‘struct opt

---

et la ligne incriminée du code tli.c :

Code:

---

st_opt_req.opt.len = OPTLEN(sizeof(struct opthdr) + sizeof(long)) ;

---

En regardant de plus pres, la structure opthdr est definie dans le fichier systeme (/usr/include/sys/socket.h) du monde Unix.
Quand je regarde le fichier (/usr/include/sys/socket.h) du monde Linux, il n'a pas grand chose à voir et biensur, cette structure opthdr n'y apparait pas.

En faisant la diff. des socket.h Unix et linux, bp de differences. Mais aussi, qq points communs. J'avais dans l'idee de placer le socket.h du monde unix avec tous les .h que mon code utilise, mais je ne sais pas si c'est la bonne stratégie car il risque d'y avoir redondance de déclarations avec le socket.h du monde Linux.
Je ne sais pas par quel bout prendre ce probleme ...
Voici mes deux sockets (en premier, le socket.h de linux; en second, celui d'unix utilisé par mon code):

La tache semble rude et trop complexe pour moi ! Avez vous des idees sur comment je pourrais traiter le pb ?

Merci a vous !

J'ai déjà eu le problème en prog socket que j'ai voulu porter sous Linux. Effectivement certaines spécificités étant différentes sous Linux, j'ai dû adapter mon code. Toutefois, à la différence de toi, c'est que c'était mon code que je portais donc si qqchose que j'utilisais sous unix ne se retrouvait pas sous Linux, ben je savais où aller pour le retrouver. Ou bien si ce qqchose n'était pas vraiment important, je pouvais le virer sans crainte.

Déjà il ne faut surtout pas apporter les .h de ton Solaris. Car les .h sont adaptés à ton système. Si la structure opthdr n'existe pas dans le .h Linux, ce n'est pas en amenant le .h Solaris que tu vas la créer. Ou plutôt tu créeras une structure inutilisée. Et tu risques de perdre des outils utilisés mais dont t'auras pas les headers. C'est un peu comme mettre une boite de vitesse de voiture de course sur un autocar quoi. Ce n'est pas pour ça que tu transformeras ton autocar en voiture de course...

Donc il te faut aller sur Solaris et voir dans les man à quoi sert ce opthdr (opt header ?) et voir ensuite sur Linux si qqchose le remplace ou alors si ça n'aurait pas par hasard été supprimé...
