To All, Greetings
I'm trying to build my first iPhone app which has some Kerberos
functionality
So I have the files asn1_encode.h and asn1_encode.mm, etc... ....
Inside my App control AppController.mm
I call the relevant procedures/functions as I need them
When I compile I get the following
(red circle white x) "_asn1_make_etag", referenced from:
_encode_as_req in AppController.o
_encode_as_req in AppController.o
_encode_as_req in AppController.o
_encode_as_req in AppController.o
_encode_as_req in AppController.o
(red circle whit x) "_asn12krb5_buf", referenced from
_encode_as_req in AppController.o
...
...
...
the "... in AppController.o" lines correspond to the number of times
the function "... referenced from:" is called in the code
So I call asn12krb5_buf once so it appears once.
I call asn1_make_etag 5 times so it appears 5 times.
The functions exists in the other files and are called using
#import "asn1_encode.h"
#import "asn1_make.h"
etc..
There is no other details about what the error is???
any ideas
Strictly speaking, these are linker errors, not compiler errors. Your
encode_as_req() function is calling asn1_make_etag() and
asn12krb5_buf(), but the linker can't find the definitions of those
two functions.
Your #imports are probably fine, assuming you didn't see any compiler
warnings about those functions. Instead, you need to find out where
asn1_make_etag() and asn12krb5_buf() are supposed to be and why the
linker doesn't see them.
* Make sure those two functions are actually implemented in some file.
Watch out for any #if that can hide an otherwise normal implementation.
* Make sure that file is being compiled by your project. Adding
`#error compile me!` to the top of asn-whatever.mm is a good way to
triple-check that; if you get no error, it's not being compiled.
* Beware of C++ name-mangling. If your asn-whatever.mm file says
`extern "C"` in it, then you might need to rename it to asn-whatever.m.
