hi,

I can't compile my program.

It's not an include problem.

[root(at)fedora src]# gcc postgresc.c -o postgresc
/tmp/ccP2I1Md.o(.text+0xd): dans la fonction exit_pg :
: undefined reference to `PQfinish'
/tmp/ccP2I1Md.o(.text+0x78): dans la fonction main :
: undefined reference to `PQsetdbLogin'
/tmp/ccP2I1Md.o(.text+0x89): dans la fonction main :
: undefined reference to `PQstatus'
/tmp/ccP2I1Md.o(.text+0x126): dans la fonction main :
: undefined reference to `PQerrorMessage'
collect2: ld a retourn 1 code d'tat d'excution
