[lldb-dev] [ASTImporter][macOS] Cannot link debugserver, keychain error

[Stefan Gränitz via lldb-dev]

Hi Gabor

Is this behavior reproducible with the current upstream LLDB? (after https://reviews.llvm.org/D55013)
Did you follow the instructions in docs/code-signing.txt?

My changes that landed last week kept the default behavior intact: build debugserver from source and code sign with lldb_codesign.
In order to change this you can configure with:

* -DLLDB_USE_SYSTEM_DEBUGSERVER=ON to use a copy of the system's debugserver instead
* -DLLDB_NO_DEBUGSERVER=ON to have no debugserver at all

Best
Stefan
