The error “ld: library not found for -lXXX” appears when running an Xcode project, indicating that the linker can’t locate a static library your project relies on.
You may see at least one of the following:
ld: library not found for -lsystem
ld: library not found for -lssl
ld: library not found for -lgfortran
Here’s what you need to do.
#1 Add the Missing Library to Your Project
Locate the missing library and add it directly to your Xcode project. This ensures that the necessary files are included, avoiding linker issues.
#2 Update “Library Search Paths” Build Setting
Navigate to your Xcode project settings and adjust the “Library Search Paths” build setting. Include the directory where the missing library is stored, helping the linker find it during the build process.
#3 Revise “LD_LIBRARY_PATH” Environment Variable
Update the “LD_LIBRARY_PATH” environment variable to include the path of the static library. This guides the linker to the correct location during the build, resolving the library not found error.
#4 Specify a Path
Consider adding the path -L/Library/Developer/CommandLineTools/usr/lib/swift_static/macosx/ as an extra measure. This can be particularly helpful based on community feedback.
Some have successfully used -L/opt/local/lib to resolve similar linker issues on macOS.
