XCode 4 adding dylib

由 北城以北 提交于 2019-11-27 02:38:50
问题 I am trying to create and then add the dylib to a project. I created it by using the "Cocoa-Library" template and setting the type to "Dynamic" (not sure if it should be dynamic or static...). Then I created a simple obj-c class called Test and wrote a method in it that prints out something to console. I compiled and used the generated .dylib file and put it in another project. Now whenever I try to use it, I get this message on runtime" dyld: Library not loaded: /usr/local/lib/TESTLib.dylib

install_name_tool to update a executable to search for dylib in Mac OS X

问题 I have a dynamic libray libtest.dylib that is installed in /PATH/lib , and an execution binary, myapp, that uses the dylib installed in /PATH/bin . I can run myapp to find the dylib as follows (Is it OK to use DYLD_LIBRARY_PATH on Mac OS X? And, what's the dynamic library search algorithm with it?): DYLD_LIBRARY_PATH="/PATH/lib" myapp I think I can use install_name_tool to update the library and executable so that the library can be found with rpath. I used the hints in this post - How can I

Apple Mach-O linker (id) warning : building for MacOSX, but linking against dylib built for iOS

问题 Starting from some point in the past xCode 4 in complaining about linker problems: ld: warning: building for MacOSX, but linking against dylib built for iOS: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/System/Library/Frameworks//CoreGraphics.framework/CoreGraphics I have checked everything but still nothing suspicious in the config and it compiles and runs. The only thing that I see it is double slashes before CoreGraphics.framework, why I do not know.

How do I create a dynamic library (dylib) with Xcode?

问题 I'm building few command-line utilities in Xcode (plain C, no Cocoa). I want all of them to use my customized version of libpng, and I want to save space by sharing one copy of the library among all executables (I don't mind re-distributing .dylib with them). Do I need to do some magic to get libpng export symbols? Does "Link Binary With Libraries" build phase link statically? Apple's docs mention loading of libraries at run time with dlopen , but how I can make Xcode create executable

How to print a list of symbols exported from a dynamic library

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-11-26 18:47:30
问题 So I've been trying to get dynamic libraries to work in my XCode project under Mac OS X. So far no joy. I am able to load the dylib file, but when I call dlsym to get the function pointer, it returns 0 and dlerror says symbol not found. So I am wondering if there is a simple way to list the symbols that are exported from a dylib file. Any ideas would be great. 回答1: man 1 nm https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/nm.1.html For example: nm -gU

How to use dylib in Mac OS X (C++)

由 南笙酒味 提交于 2019-11-26 15:24:30
问题 I made an application (an executable) calling some dylib successfully, However, the dylib files and the executable are in different directory. I added the directory contains dylib files to the $PATH environment variable, however, it still doesn't load. I copy all the dylib files to the executable, the program finally runs. This confirms the dylib files have no problem. However, How can I tell the OS to find it? In windows, I just need to add the directory path contains dll files to $PATH.

Xcode 6 and Embedded Frameworks only supported in iOS8

When using an embedded framework (dyld) in Xcode 6.0.1 with deployment target less that iOS 8 I get: Build is successful Runtime library loading error Error: dyld: Library not loaded: @rpath/ObjectiveLyricsTouch2.framework/ObjectiveLyricsTouch2 Referenced from: /private/var/mobile/Containers/Bundle/Application/DC65ACA9-98E5-46CD-95F8-829D3416F6C0/musiXmatch.app/musiXmatch Reason: image not found (lldb) For some time I was thinking that this is my problem as well, but for normal apps ( non-iOS-8-extension ) you just need to change one build setting in your casual Xcode 6 iOS Universal Framework

Conflict between dynamic linking priority in OSX?

由 試著忘記壹切 提交于 2019-11-26 11:03:18
问题 There is a dynamic-linking-conflict between different libjpeg dynamic libraries on OSX. First there is a standard native libJPEG.dylib (in /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/). But if you are using MacPorts, you can also have a port-related libjpeg.dylib in (in /opt/local/lib). The latter may for example have been installed as a dependency for some other port. This creates a problem when you link against your system libJPEG (which is preferred). Then if /opt

dyld: Library not loaded … Reason: Image not found

When trying to run an executable I've been sent in Mac OS X, I get the following error dyld: Library not loaded: libboost_atomic.dylib Referenced from: /Users/"Directory my executable is in" Reason: image not found Trace/BPT trap:5 I have installed the boost libraries and they are located in /opt/local/lib . I think the problem has something to do with the executable only looking in the directory it is in as when I paste the 'libboost_atomic.dylib' in there, it doesn't mind about it anymore. Unfortunately then it complains it can't find the next boost library. Is there an easy way to fix this?
