Hello toolchain@,
When building a recent (r275944) LLDB on stable/11, I've encountered
build failures in tools/lldb-mi (missing symbol llvm_regexec, need to
link against LLVMSupport). This problem doesn't occur on (at least) OS
X, so perhaps the LLVM build bots don't see it. It looks like the fix is
pretty simple:
```diff
--- a/tools/lldb-mi/CMakeLists.txt
+++ b/tools/lldb-mi/CMakeLists.txt
@@ -89,6 +89,10 @@ if ( NOT CMAKE_SYSTEM_NAME MATCHES "Windows" )
target_link_libraries(lldb-mi pthread)
endif ()
+if ( CMAKE_SYSTEM_NAME MATCHES "FreeBSD" )
+ set(LLVM_LINK_COMPONENTS support)
+endif ()
+
llvm_config(lldb-mi ${LLVM_LINK_COMPONENTS})
set_target_properties(lldb-mi PROPERTIES VERSION ${LLDB_VERSION})
```
Is this problem the result of some misunderstanding on my part, or is it
a valid issue that I should take upstream (together with the above
patch)?
Jon

We have a FreeBSD 11 LLDB build bot, which was green as of r272672:
http://lab.llvm.org:8011/builders/lldb-amd64-ninja-freebsd11
although I'm not certain exactly what it tests. I build regularly on
my stable/10 desktop though and lldb-mi built successfully.
