sudo apt-get install llvm-14 \ llvm-14-dev \ clang-14 \ liblld-16 \ liblld-16-dev \ libllvmspirvlib15 \ libllvmspirvlib-15-dev

sudo apt-get install -y libopencl-clang-14-dev

Error

intel-graphics-compiler/igc/IGC/../../inc/common/secure_mem.h:35:16: error: redefinition of ‘errno_t fopen_s(FILE, const char, const char)’ 35 | inline errno_t fopen_s( FILE pFile, const char filename, const char mode )

Note

There are also a bunch of similar errors for other functions in secure_mem.h and secure_string.h

Hi @hector-cao, this is most likely unrelated, but mixing LLVM versions (libllvmspirvlib-15 vs llvm-14) won't work. Can you retry building using all components on version 14? We also don't fully support building against system LLVM; building from sources is the preferred option.

@hector-cao Please provide version of IGC you're building, as IGC has been building fine for me on 23.10.

mixing LLVM versions (libllvmspirvlib-15 vs llvm-14) won't work.

Yep. To build IGC on 23.10, I install following packages:

$ sudo apt install \
    libc-dev libz-dev libpng-dev libboost-all-dev \
    libnl-genl-3-dev ocl-icd-opencl-dev \
    git ca-certificates gcc g++ \
    pkg-config make cmake ninja-build \
    flex bison patch swig python3-mako valgrind \
    llvm-spirv-14 libllvmspirvlib-14-dev \
    clang-14 llvm-14-dev liblld-14-dev libopencl-clang-14-dev

(Valgrind is for optional Valgrind annotations.)

We also don't fully support building against system LLVM; building from sources is the preferred option.

It has worked fine for me, as long as I make sure that everything is built with the same LLVM version (as LLVM changes ABI between versions).

@pszymich I think this can be closed:

• Ubuntu does not support 23.10 any more
• LLVM does not support mixing use of different LLVM versions (is not ABI/API compatible between them)

Closing after 3 months of no response from ticket reporter.
