Due to recent changes, rebuilding with cmake and ninja in an existing build on
OSX gets the following linker errors (note: it builds fine from scratch):
$ ninja
. . .
Undefined symbols for architecture x86_64:
"_liblldb_coreVersionString", referenced from:
lldb_private::GetVersion() in lldb.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
. . .
ninja: build stopped: subcommand failed.
I've tried to fix this wirth the attached patch, but it gets a warning about
multiple rules for LLDB_vers.c:
$ ninja
[1/1] Re-running CMake...
. . .
ninja: warning: multiple rules generate tools/lldb/source/LLDB_vers.c.
builds involving this target will not be correct; continuing anyway
. . .
[13/13] Creating executable symlink bin/lldb
Does anyone know how to fix this the right way to avoid these warnings?
BTW, anyone know why I also get the following warnings? (They are unrelated to
the linker error or the patch, but just curious):
. . .
[6/13] Linking CXX shared library lib/liblldb.3.8.0.dylib
ld: warning: cannot export hidden symbol lldb::SBListener::GetSP() from
