Xcode linker error: file too small for architecture x86_64

Question

I\'m developing an application in Xcode.

When I try to build, this error comes up:

ld: in /Users/theodore/Library/Developer/Xcode/DerivedData/Tower-b         


        

Answer 1

Step 1. Go to: Project > Build Settings > Search Paths

Step 2. Set "Always Search User Paths" to Yes

Step 3. Build the project (You'll get a warning but the project will build.)

Step 4. Set "Always Search User Paths" back to No and build again to eliminate the warning

Answer 2

To automatically fix this issue Build Script Phase can be added. Goto Xcode -> Your Project -> Your Target -> Build Phases -> + -> New Run Script Phase

Rename it to Xcode Link Fix and move it above Compile Sources phase. Paste this into script body:

# Legacy build system
legacy_dir=`dirname "${LD_DEPENDENCY_INFO_FILE}"`
if [ -d "${legacy_dir}" ]; then
    find "${legacy_dir}" -size 0 | while read -d $'\n' file; do
        rm "$file"
    done
fi

# New build system
if [ -d "${OBJECT_FILE_DIR_normal}" ]; then
    find "${OBJECT_FILE_DIR_normal}" -size 0 | while read -d $'\n' file; do
        rm "$file"
    done
fi

This script checks for object files with zero size and removes them so when compilation is done in next step it success.

You need to add this script for every app target if you have many.

This script takes ~0.1 second to run and saves you from full project rebuild.

Answer 3

just remove this file by run cmd in your terminal app:

rm /Users/theodore/Library/Developer/Xcode/DerivedData/Tower-bkpdifuqssebjdgurzmtirbxejnn/Build/Intermediates/Tower.build/Debug/Tower.build/Objects-normal/x86_64/TWRAppDelegate.o

Answer 4

You can just delete the TWRAppDelegate.o file and continue your build. Copy the full path mentioned in the error message and paste it behind an 'rm' command in your terminal. There's no need to clean/rebuild, delete derived data, add/remove the file from the project, etc.
