dylib

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 specify the rpath in a dylib? . In lib, I executed this command to add rpath. install_name_tool -id "

When I brew doctor I get the following errors: dyld: Library not loaded: /usr/lib/libltdl.7.dylib Referenced from: /usr/local/bin/php Reason: image not found Error: No available formula for zlib The file libltdl.7.dylib is not in my /usr/lib directory, but there are several other .dylib files. I'm running 10.8.1 with the latest version of Xcode (4.4.1) and its Command Line Tools installed. Any idea how to solve these errors? kenorb Try to re-install libtool by: brew reinstall libtool --universal && brew unlink libtool && brew link libtool If that doesn't help, try removing libtool completely,

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 without complaining about missing symbols? I think I've figured it out: libpng wasn't linking properly,

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. MK. man 1 nm https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/nm.1.html For example: nm -gU /usr/local/Cellar/cairo/1.12.16/lib/cairo/libcairo-trace.0.dylib Use otool : otool -TV your.dylib OR nm -g

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. What do I need to do for Mac OS X? Thanks a lot! After reading the link that Justin provided, I was

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/local/lib is in DYLD_LIBRARY_PATH, that path will be prioritised when searching for a dynamic lib,

Xcode 7 In Target > BuildPhases > Link Binary With Libraries > tap + button When choosing frameworks to add, you cannot find *.dylib, you'll see *.tbd instead. What is the reason for this? **For people who need dylib, follow from this post Choose "Add other" Once in the file selection window do "CMD"+Shift+G (Go to folder) & type /usr/lib/ From /user/lib you can find the *.dylib files I've scoured Google but the only thing I can find so far is the following quote from the Apple developer forums : For those who are curious, the .tbd files are new "text-based stub libraries", that provide a much
