Segmentation fault: 11 when attempting to codesign .app

Question

I haven\'t been able to find a definition for this error in relation to codesigning. I\'m really quite stumped as of what to do.

The error occurs when attempting to exec

Answer 1

A solution I found on the Apple forum worked for me: first, run the following command to find your identity's hex ID:

$ security find-identity -v
1) A048017A43F8C9C993128B0101B81CD07049601E "lldb_codesign"
...

Then you can use that hex identifier to sign:

codesign -s A048017A43F8C9C993128B0101B81CD07049601E /usr/local/bin/gdb

Some other tips I came across while debugging this:

• You have to give the full path to the binary (/usr/local/bin/gdb, not just gdb). It won't look on the PATH, I assume for security reasons.
• You have to run the codesign as root if the directory your binary is in is not user-owned.
