use dynamic library in xcode 6 have error: Library not loaded: /usr/local/lib/xxx.dylib Reason: image not found

Question

i have a beginner of cross-platform programming. my project is a simple 3d project it works on windows well, it is mananged by vistual sutido 2013.and then, i create projects under xcode 6.

there is a Core library in my project, i have compiled it as a dll file under windows, and static link it by a tool which is named Editorbuilder, this tool used to build editor script. the Core project which is Core.vcxproj generate a Core.dll under ProjectRoot/Binaries/Win32/Debug/. EditorBuilder.vcxproj generate a EditorBuilder.exe under ProjectRoot/Binaries/Win32/Debug. if i run this tool in visual studio or the console window, it works well.

under macos, i use xcode 6. first i have create a dynamic library project, it has a product libCore.dylib, it will generate to ProjectRoot/Binaries/Mac/Debug. and then i create the EditorBuilder project in xcode 6 which is a normal command line tools,and add the reference of libCore.dylib to the product:

the picture of projects

the files is generated success

it compile success, and works well if i debug EditorBuilder Under Xcode6 use Ctrl + R. but when i run EditorBuilder in the terminal or double click it, it can not launch up because this :

/Users/bodong/Documents/Hikari/Binaries/Mac/Debug/EditorBuilder ; exit;
bodeMacBook-Pro:~ bodong$ /Users/bodong/Documents/Hikari/Binaries/Mac/Debug/EditorBuilder ; exit;
dyld: Library not loaded: /usr/local/lib/libCore.dylib
  Referenced from: /Users/bodong/Documents/Hikari/Binaries/Mac/Debug/EditorBuilder
  Reason: image not found
Trace/BPT trap: 5
logout

so my question is that the libCore.dylib is in the same directory, why the EditorBuilder process can't find the dylib? why the EditorBuilder can find the dylib when run it in xcode 6 with Ctrl + R ?

what's the difference between windows dll and macos dylib? what is the search strategy under macos?

---

ps: if i create a directory /usr/local/lib,and copy libCore.dylib to this dir, it works well. how to make the EditorBuilder load the dylib which is the same parent dir.????

Answer 1

there is a install directory in the build settings, change this directory to the output directory, it works well. but i don't know if i deploy this app to another mac, should it works well?
