Hello, I update my building scripts to build LLVM 4.0 RC1 (with clang, lldb, libc++, libc++abi, lld) on CentOS 6 and I got a lot of undefined symbols during linking LLDB. 

I'm using clang-3.9 and this configuration:

-DLLVM_TARGETS_TO_BUILD="X86" 
-DCMAKE_BUILD_TYPE=Release 
-DCMAKE_C_COMPILER=/usr/bin/clang
-DCMAKE_CXX_COMPILER=/usr/bin/clang++
-DCMAKE_EXE_LINKER_FLAGS="-lc++abi -lc++" 
-DCMAKE_EXE_LINKER_FLAGS="-lc++abi -lc++" 
-DCMAKE_SHARED_LINKER_FLAGS="-lc++abi -lc++" 
-DCMAKE_MODULE_LINKER_FLAGS="-lc++abi -lc++" 
-DLLVM_ENABLE_LIBCXX=ON 
-DLLVM_LIBDIR_SUFFIX=64 
-DCMAKE_INSTALL_PREFIX=/usr 
-DLLDB_DISABLE_PYTHON=1 
-DTARGET_TRIPLE="x86_64-pc-linux-gnu" 
-DLIBCXX_INSTALL_EXPERIMENTAL_LIBRARY=ON 
-DLLVM_ENABLE_LLD=ON

List of undefined symbols and invocation is next:

Hi Hana,

these are all symbols that should be exposed by liblldb (which is
present on your link line), so I am not sure what could be the problem
here.

Could you inspect the symbols exposed by liblldb (objdump -T
lib64/liblldb.so) to see if the symbols are present there?

Also, to help us narrow down the problem could you prune the list of
cmake flags you are configuring the build with (i.e. remove everything
libc++ and lld related) and try to rebuild that way?

thanks,
pavel

Hi Pavel,

thank you for you response.

objdump -T showed that there are no symbols defined in liblldb.so.

After few compilations I found that problem is with linking with LLD (-DLLVM_ENABLE_LLD=ON) without the directive everything is ok.

This is interesting. I am not sure why LLD should have a problem with
linking liblldb.so.

I guess it has something to do with the version script we use to
restrict the exported API, but I am not sure whether that is an lld
bug, or a bug in how we are setting it up.

Adding Ruiu, in case he has any insight.

cheers,

I looked and only liblldb.so library is using add_llvm_symbol_exports function from cmake/modules/AddLLVM.cmake.

Maybe there is a problem with calling lld somehow with version script. The problem can be there for long time 4.0RC1 is my first build with LLD previous ones was with GOLD.

libclang does the same thing as well, however it does it indirectly by
setting the LLVM_EXPORTED_SYMBOL_FILE variable. I am not sure why
would that make any difference, but maybe you can try if linking
liblldb that way fixes anything (or indeed, checking whether libclang
exports the expected symbols).

Apart from that, I don't really have any good idea.
