python3 $DPCPP_HOME/llvm/buildbot/configure.py --shared-libs --cmake-opt="-DCMAKE_EXPORT_COMPILE_COMMANDS=1"
python3 $DPCPP_HOME/llvm/buildbot/compile.py --verbose

Answer 2 · 2024-10-30T23:24:10.000Z

@keryell I've seen this build error before. It happens when you use zstd static libraries that were not built with -fPIC flag.
How did you obtain the zstd library /usr/lib/x86_64-linux-gnu/libzstd.a?
In CI, we got the zstd library via standard package manager (apt install libzstd-dev) and shared build seems to work fine: https://github.com/intel/llvm/actions/runs/11586255964/job/32256545435

Answer 3 · 2024-10-30T23:39:43.000Z

As a quick workaround, you could disable ZSTD usage in buildbot/configure.py file https://github.com/intel/llvm/blob/sycl/buildbot/configure.py#L67 by changing llvm_enable_zstd to OFF.
zstd is optional and is only used for device image compression.

Answer 4 · 2024-11-01T00:30:54.000Z

Thanks for the work-around.
This is the library coming with the latest Ubuntu:

dpkg -S /usr/lib/x86_64-linux-gnu/libzstd.a
libzstd-dev:amd64: /usr/lib/x86_64-linux-gnu/libzstd.a

Perhaps it is an issue in the package provided with Ubuntu 24.10?
I cannot find any other bug with this combination but https://bugs.kde.org/show_bug.cgi?id=495217. But it is unclear whether it is related.

I think so. I've filed a bug report: https://bugs.launchpad.net/ubuntu/+source/libzstd/+bug/2086543
In the meanwhile, here the PR to detect if zstd static library is position-independent or not and accordingly enable zstd in DPCPP: #15970

Thanks for filing the bug report!

Few days ago I removed the line https://github.com/intel/llvm/blob/sycl/buildbot/configure.py#L182C10-L182C37

        "-DLLVM_USE_STATIC_ZSTD=ON",

and it solved the problem for me.
I am curious about the rationale to use static zstd library instead of relying on shared library when using globally shared libraries?

If we use static zstd library, the end users of DPC++ do not have to install the libzstd-dev package. zstd libraries are not installed by default on many OS that DPC++ supports.
