--- Comment #7 from Evangelos Foutras <evange...@foutrelis.com> ---
Either this issue has regressed in LLDB 6.0.0 or the LLVM package I pushed to
Arch Linux is buggy.
I'm doing an out-of-tree build of LLDB 6.0.0 with LLVM_LINK_LLVM_DYLIB=ON. The
resulting lldb-{server,test} binaries link to both libLLVMSupport.a and
libLLVM-6.0.so and result in the following runtime errors:
=========================
$ lldb-server
: CommandLine Error: Option 'disable-symbolication' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
$ lldb-test
: CommandLine Error: Option 'help-list' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
=========================
I'm unable to reproduce the issue on Fedora Rawhide, but I believe that has to
do with the fact that Fedora's libLLVM-6.0.so links statically to libstdc++
(not sure why this has any effect on this problem though). If I build my LLVM
package with static libstdc++ like Fedora does
(-DCMAKE_SHARED_LINKER_FLAGS="-Wl,-Bsymbolic -static-libstdc++") then
lldb-{server,test} run fine.
I also tried to repro on Debian without any success. (Perhaps it matters that
they do an in-tree build?)
For now I've resorted to removing all references to /usr/lib/libLLVMSupport.a
from the generated build.ninja file. This seems to allow the above tools to
run.
