Tryibg to build LeelaChessZero

epsheldoni

I am attempting to build LeelaChessZero UCI chess engine. I get the following error:

/usr/local/bin/x86_64-unknown-freebsd14.2-ld: /usr/bin/../lib/LLVMgold.so: error loading plugin: Cannot open "/usr/bin/../lib/LLVMgold.so"
c++: error: linker command failed with exit code 1 (use -v to see invocation)
[279/365] Compiling C++ object liblc0_lib.so.p/src_neural_xla_onnx2hlo.cc.o
ninja: build stopped: subcommand failed.

Any ideas? I am able to build it successfully on FreeBSD and OpenBSD.

Thanks,
Sheldon Wiedeman

You may have already done this, but ensure you install the development environment dependencies:
sudo pkg install -g 'GhostBSD*-dev' llvm bash
Open a terminal, and run:
bash
Confirm the LLVMgold.so exists:
find /usr/local -name LLVMgold.so
If the file is found at /usr/local/llvm19/lib/LLVMgold.so, then set the plugin path:
export LDFLAGS="-Wl,-plugin=/usr/local/llvm19/lib/LLVMgold.so"
You may want to add:
export CC=clang export CXX=clang++ export PATH="/usr/local/llvm19/bin:$PATH"
Rebuild:
meson setup build --buildtype=release ninja -C build

Vimanuelt,

Thanks for your reply. I can confirm that LLVMGold.so does not exist.
I will continue to investigate further.
