In my Cocoa application I’m using a third party C-library that is compiled in command line and available in a custom location.<\/p>\n

In my Xcode project I can define where the library’s header files are located and where the library is looked during linking:<\/p>\n

Header files location (HEADER_SEARCH_PATHS<\/code>):<\/p>\n

Target > Build Settings > Search Paths > Header Search Paths\n<\/code><\/pre>\n
Library location during linking (LIBRARY_SEARCH_PATHS<\/code>):<\/p>\n
Target > Build Settings > Search Paths > Library Search Paths\n<\/code><\/pre>\n
But how do I define the library’s runtime location ? At the moment when I run my Cocoa application in Xcode (cmd-r<\/code>) I get an error from dynamic linker:<\/p>\n
dyld: Library not loaded: \/usr\/local\/lib\/libfoo.1.dylib\n  Reason: image not found\n<\/code><\/pre>\n
My application runs without problems when I create directory \/usr\/local\/lib<\/code> and a symbolic link to the library.<\/p>\n
man dydl<\/code> tells about three related environment variables:<\/p>\n
    \n
  • DYLD_LIBRARY_PATH<\/code><\/li>\n
  • DYLD_FALLBACK_FRAMEWORK_PATH<\/code><\/li>\n
  • DYLD_FALLBACK_LIBRARY_PATH<\/code><\/li>\n<\/ul>\n
    I know how to set the variables on a bash terminal (see e.g. Where do I set DYLD_LIBRARY_PATH on Mac OS X, and is it a good idea?), but how do I set environment variables for Xcode ?<\/p>\n
    I’m running OS X 10.8.x and Xcode 4.5.x.<\/p>\n","protected":false},"excerpt":{"rendered":"
