Bug ID: 28017
Summary: error: failed to load objectfile for static-linking
archives?
Product: lldb
Version: 3.6
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: chris+l...@qwirx.com
CC: llvm-b...@lists.llvm.org
Classification: Unclassified
I'm having trouble debugging my application with LLDB on Mac because it seems
to fail to find some of the compiled object files, which are inside a static
link library (.a file). Objects which are compiled directly into the binary
seem to be OK.
I get errors like this when I first try to access line-level information:
(lldb) l BackupStoreFile.cpp
error: backupstore.a(BackupStoreFile.o) failed to load objfile for
/Users/chris/projects/2004/boxi/bb-git/bin/bbackupquery/../../debug/lib/backupstore/backupstore.a
error: backupstore.a(BackupCommands.o) failed to load objfile for
/Users/chris/projects/2004/boxi/bb-git/bin/bbackupquery/../../debug/lib/backupstore/backupstore.a
...
error: common.a(autogen_CommonException.o) failed to load objfile for
/Users/chris/projects/2004/boxi/bb-git/bin/bbackupquery/../../debug/lib/common/common.a
error: Could not find source file "BackupStoreFile.cpp".
I suspect that either lldb does not fully understand the .a archive format, or
another bug prevents it from locating the correct object file inside the
archive. It is definitely there:
chris@Chriss-MacBook-Pro(backupstorepatch)$ ar t
/Users/chris/projects/2004/boxi/bb-git/bin/bbackupquery/../../debug/lib/backupstore/backupstore.a
__.SYMDEF
BackupAccountControl.o
...
BackupStoreDirectory.o
BackupStoreFile.o
BackupStoreFileCmbDiff.o
