Hi everyone, I'm doing something really obviously wrong, but I don't
know what.
I can gcc -c -o file.o file.c and get a binary object.
I do this for the main and two "helper" .c files
This works, then I get a bunch of .o files.
then you usually do
gcc -o <final executable name> <main.o> <myfile1.o> <myfile2.o>
and gcc does the linking.
In thsi case, myfile2.c uses ldap_init and ldap_simple_bind, and
myfile2.h inludes ldap.h.
At this point, there is no ldap.o, just the ldap.h from
/usr/include/ldap.h so compile of everything stalls, saying that there
is an undefined reference to the function ldap_init and ldap_simple_bind.
Testing indicates that you can do:
int main() {
thingy_do(123);
}
and it will happily do a gcc -c -o main main.c and create the object,
which is what it should -- it's not until we link .o's to create a real
executable that the system wants to make sure the executable code exists.
The bit that makes me think I'm stupid is that it seems that neither gcc
or I can find the source (.c) or compiled binaries (.o) which implement
the structures and functions defined in ldap.h. What am I doing wrong?
Where are the .c and .o files supposed to be on a regular linux system?
Where on gentoo? Have I missed a crucial flag?
Thanks in advance...
