Hello!
I try to use libpq++ (linux: redhat4.2, postgresql-(devel)?-6.2 GNU c)
And i have problem with linking:
[root(at)3dom neko]# g++ -I/usr/include/postgres/ -lpq++ -o a a.cc
/tmp/cca032541.o: In function
ain':
/tmp/cca032541.o(.text+0x22): undefined reference to gConnection::Exec(char
const *)'
...
And more like this. But where is this famous exec?
[root(at)3dom neko]# nm -C /usr/lib/libpq++.a | grep 'Exec(char'
00000348 T PgConnection::Exec(char const *)
U PgConnection::Exec(char const *)
All right. In libpq++.
And I use this lib?
[root(at)3dom neko]# mv /usr/lib/libpq++.a .
[root(at)3dom neko]# g++ -I/usr/include/postgres/ -lpq -lpq++ -o e e.cc
ld: cannot open -lpq++: No such file or directory
Yes. We were use before this.
And include-s is too works.
My first program:
-------- x --------
#include <postgres/libpq++.h>
#ifndef PGDATABASE_H
main(){;};
#else // PGDATABASE_H
#include <iostream.h>
main(){
ExecStatusType XStat;
PgDatabase conn("tval");
XStat=conn.Exec("select oid from szak order by oid ;");
for (int i=0,max=conn.Tuples();max>i;i++) {
cout << conn.GetValue(i,0) << endl;
}
}
#endif // PGDATABASE_H
-------- x --------
I mean, i try all what i can. But somewhere i must done a mistake.
BUT where?!
Please help me...
