[c++] Problème de compilation

Bonsoir,

Désolé de demander encore votre aide mais j'ai enfin bien avancer dans mon projet et voilà que je retombe sur un problème....grrr !

Voilà le truc le projet que je voudrais rassembler contient:
2 Serveur TCP et leur .h
1 client et son .h
1 fichier de calcul RObuSimul.cpp et son .h
et RobuLAB.cpp qui contient mon main(int argv....

J'ai donc un make file:

all: essai
essai: RobuSimul.o ServeurTCP9988.o ServeurTCP9999.o ClientTCP.o Robulab.o
g++ -o essai RobuSimul.o Robulab.o ServeurTCP9988.o ServeurTCP9999.o ClientTCP.o

RobuSimul.o: RobuSimul.cpp RobuSimul.h
g++ -o RobuSimul.o -c RobuSimul.cpp -Wall -ansi

ServeurTCP9988.o: ServeurTCP9988.cpp ServeurTCP9988.h
g++ -o ServeurTCP9988.o -c ServeurTCP9988.cpp

ServeurTCP9999.o: ServeurTCP9999.cpp ServeurTCP9999.h
g++ -o ServeurTCP9999.o -c ServeurTCP9999.cpp

ClientTCP.o: ClientTCP.cpp ClientTCP.h
g++ -o ClientTCP.o -c ClientTCP.cpp

Robulab.o: Robulab.cpp
g++ -o Robulab.o -c Robulab.cpp -Wall -ansi

Et quand je compil le tout il me dit :

$ make
g++ -o Robulab.o -c Robulab.cpp -Wall -ansi
RobuSimul.h:41: error: conflicting declaration ‘typedef struct LAB80FeedbackStruct LAB80FeedbackStruct’

Robulab.cpp: In function ‘int main(int, char**)’:

Robulab.cpp:29: error: ‘Serv9999’ was not declared in this scope
Robulab.cpp:30: error: ‘Client’ was not declared in this scope
make: *** [Robulab.o] Erreur 1

Mais voilà j'ai beau cherché je vois pas pourquoi il me dit confilcting Déclaration je n'est déclaré mes fonction que dans le point .h.
Ce que je fai dans mon main c'est créer un objet de la classe!

A quoi peut correspondre "conflicting declaration"?
Merci beaucoup !
