Hello,
I am new to LLDB and don't quite understand the relationship between
llvm.org and Apple. However, I would like to fix a bug that is
preventing me from debugging some code that I compiled with Swift 4.2
on Ubuntu 18.04. Specifically, when I use the Apple/Swift LLDB with
this code and LLDB_SWIFT_DUMP_DIAGS=1 enabled I get errors that say
"<unknown>:0: error: missing required module 'Clibavahiclient'".
However, I went looking and to my novice eyes it looks like the module
(symbols?) that LLDB is looking for are on the file system.
Specifically, there is a file (Clibavahiclient-2J8WBHG3Q43SC.pcm)
which is an ELF binary with lots of DWARF symbols, including the
following:
0x00000026: DW_TAG_module
DW_AT_name ("Clibavahiclient")
DW_AT_LLVM_config_macros ("\"-D__swift__=40150\"")
DW_AT_LLVM_include_path
("/work/AvahiClient/.build/checkouts/Clibavahiclient.git--4733535768090925471")
DW_AT_LLVM_isysroot ("/")
I have posted a full write-up with source code and all the symbols here:
https://github.com/TaborKelly/AvahiClient
Am I on the right track? Does Clibavahiclient-2J8WBHG3Q43SC.pcm have
the information that LLDB is missing? If so, how would I go about
getting that knowledge to LLDB?
Thank you,
Tabor
