How to connect a library for assembly in Xcode?

Question

Objective-C

There is XCode.
And suppose two projects - the ABC application and the libABC library.
How to force XCode to link ABC with libABC?

Answer 1

In order to work properly with an external library, XCode needs the library file itself (the one that is .a) and the header file (.h) with the signatures of the functions you are going to call.
Add both files to the project, add the library file to Build Phases - Link binary with libraries, import the .h file where you call the functions from this library (#import "xxxxxx.h")

Answer 2

and it would be nice to chat with someone in Jabber/GTalk about the basics of working with XCode

Answer 3

Help -> Search: "Linking to a Library". Select the Tools Guides section.

Answer 4

there is not the library that I created in XCode (without installing)

Answer 5

recreated project abc - cl.ly/BRgs
main.cpp
#include void abc();
int main (int argc, const char * argv[])
{
abc();
// insert code here...
std::cout << "Hello, World!\n";
return 0;
}
libabc.c
#include <stdio.h>
#include <string.h>
void abc() {
printf("pizdec\n");
}

при сборке ошибка cl.ly/BRjr

Answer 6

if you just attach libabc.a, then there will be no error about an unknown type, but undefined symbols will remain

Answer 7

so? no answers?

Answer 8

Those. won't it automatically build the project-library when building a project that depends on it?
