failed to link bin/lldb-server with: ../x86_64-pc-linux-gnu/bin/ld: lib/liblldbCore.a(IOHandlerCursesGUI.cpp.o): undefined reference to symbol 'halfdelay'

[stefson]

hey there, I just discovered this project and tried to compile it on x86_64 linux, following the instructions to simply execute ./build-all.sh /tmp/llvm-mingw-14.0

it all compiled nicely, but the linking of lldb fails with:

Hmm, weird. What distribution are you building it on?

In practice, if you'd add -DLLDB_ENABLE_CURSES=NO in build-llvm.sh, or add --disable-lldb to the call to build-llvm.sh in build-all.sh, I would expect this to help and fix the build - but that only avoids the issue. (Although in most cases you probably don't need the lldb built at all, when building a cross compiler.)

Here, I presume the root cause of the issue is

/lib64/libtinfo.so.6: error adding symbols: DSO missing from command line

which then causes the undefined reference to a symbol which probably was expected to be provided by that library.

Unfortunately, it doesn't ring any bells for me about what might be wrong about that library...

thanks for the fast answer,

there is more fun down the road as it tries to link lib/liblldb.so.14.0.0:

[stefson]

Can you maybe post a little patch for the build-llvm.sh file, which does -DLLDB_ENABLE_CURSES=NO for the build? The risk seems high that I will missunderstand the log of the script and waste another hour of cpu time :D

the lib in question is of course present on the system

thanks, I will patch it locally and give feedback.

Are you okay with me using gcc to compile?

[mstorsjo]

Yeah, starting the build with GCC should be totally fine. (I regularly test it mostly with GCC 9 on Ubuntu 20.04 and GCC 7 on 18.04.)

[stefson]

the patch makes it compile :)

[mstorsjo]

the patch makes it compile :)

Thanks, that's good news.

In any case, the underlying build failure of lldb on your distribution is primarily an upstream lldb bug then - which you can file at http://github.com/llvm/llvm-project/issues if you have time. To reproduce, clone llvm-project (or reuse the clone you already have under llvm-mingw) (you can try the release/14.x branch which should match what you're seeing here, and possibly also test the main branch), make a subdirectory under llvm-project/llvm named e.g. build, configure and build it like this:

$ cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;lldb"
 -DLLVM_TARGETS_TO_BUILD="ARM;AArch64;X86" -DLLVM_LINK_LLVM_DYLIB=ON
$ ninja

(The LLVM_TARGETS_TO_BUILD isn't entirely relevant, but it should reduce the compilation time a little by not building entirely irrelevant targets. It'd be interesting to know if the issue reproduces without LLVM_LINK_LLVM_DYLIB too.)

[stefson]

indeed, its possible to reproduce the issue exactly that way. propably a missing -ltinfo somewhere

funny thing is, there is no breakage in the standalone build of gentoo's dev-util/lldb
