dylib

Trying to compile the example hello_world.c from the zeromq tutorial: http://zguide.zeromq.org/page:all#Ask-and-Ye-Shall-Receive Pretty sure I have everything installed in OSX Mountain Lion. clang -Wall hwserver.c -o hwserver gives me an error: Undefined symbols for architecture x86_64: "_zmq_bind", referenced from: _main in hwserver-OgrEe6.o "_zmq_ctx_new", referenced from: _main in hwserver-OgrEe6.o "_zmq_msg_close", referenced from: _main in hwserver-OgrEe6.o "_zmq_msg_data", referenced from: _main in hwserver-OgrEe6.o "_zmq_msg_init", referenced from: _main in hwserver-OgrEe6.o "_zmq_msg

I have a collection of projects that I'm compiling as dynamic libraries. Each of these .dylibs depend on other various .dylibs that I would like to place in various other directories (i.e. some at the executable path, some at the loader path, some at a fixed path). When I run otool -L on the compiled libraries, I get a list of paths to those dependencies but I have know idea how those paths are being set/determined. They almost appear pseudo random. I've spent hours messing with the "Build Settings" in Xcode to try and change these paths (w/ @rpath, @executable_path, @loader_path, etc.) but I

I'm creating a Photoshop Plug In on OS X (Basically a Bundle / DyLib). I'm using Intel Compiler and uses OpenMP by linking against OpenMP ( libiomp5 ). When I use Static Linking it crashes Photoshop (Only on OS X, on Windows it works). So I tried dynamic linking. The host, Photoshop, uses by itself libiomp5.dylib which is available on its Framework folder. So, on Xcode I set on the Linking Part the Runpath Search Paths to @executable_path/../Frameworks/ yet when I try to load it on Photoshop it won't work. I also tried to set Runpath Search Paths to Intel Run Time Redistributable Libraries

Trying to load a shared lib out of the current '.' dir in a unit test on osx. What works on Linux and Netbsd there is a symlink _mymodule.so --> ../.libs/libmymodule.so but on osx, python's import mymodule won't find _mymodule.dylib --> ../.libs/libmymodule.dylib I've tried adding export DYLD_LIBRARY_PATH=.:$DYLD_LIBRARY_PATH to the script env, nogo. Any help appreciated. -Ed update 4/6/10: Solved with the info from krunk below. But just copying or ln -s'ing the dylib to a .so name didn't solve it completely. Still wouldn't load. But telling libtool to link the lib with the -module flag

I am trying to create a dynamic library for iOS and load it at runtime. After taking a look at this question and this answer , I have been doing it using iOSOpenDev and deploying everything on my iPhone. The xCode project for the dylib is called KDylibTwo and the files I modiefied are: KDylibTwo.h #import <Foundation/Foundation.h> @interface KDylibTwo : NSObject -(void)run; @end KDylibTwo.m #import "KDylibTwo.h" @implementation KDylibTwo -(id)init { if ((self = [super init])) { } return self; } -(void)run{ NSLog(@"KDylibTwo loadded."); } @end In order to test if my library works, after
