[BUG] failure to compile due to identifier "__int128_t" is undefined on cuda-11.6 and gcc-9.4.0

[umiswing]

Describe the bug
Try to build cudf 22.10 from source. I run ./build.sh libcudf but get a compile error:

Error processing source file binaryop/jit/kernel.cu
Compilation failed: NVRTC_ERROR_COMPILATION
Compiler options: "-std=c++17 -D_FILE_OFFSET_BITS=64 -D__CUDACC_RTC__ -default-device"
cudf/fixed_point/fixed_point.hpp(29): error: identifier "__int128_t" is undefined

1 error detected in the compilation of "binaryop/jit/kernel.cu".

gmake[2]: *** [CMakeFiles/jitify_preprocess_run.dir/build.make:78: include/jit_preprocessed_files/binaryop/jit/kernel.cu.jit.hpp] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:686: CMakeFiles/jitify_preprocess_run.dir/all] Error 2
gmake[1]: *** Waiting for unfinished jobs....

Environment overview (please complete the following information)

• Environment location: Bare-metal(Ubuntu 22.04)
• Method of cuDF install: from source

Additional context
nvcc version: 11.6
GCC version: 9.4.0
cmake version: 3.23.3
hardware: GeForce RTX 3060 Mobile / Max-Q

Can you please post the output of cmake --system-information when executed in the the <cudf_dir>/cpp/build directory

[robertmaynard]

During the compilation of JIT files the jit_preprocessed_files will try to locate the associated nvrtc library on your machine.

Therefore on machines with multiple CUDA installations, the version found via LD_LIBRARY_PATH will be selected with no regards to it being 11.5+ ( for int128 support ). So you should also ensure that LD_LIBRARY_PATH points to the lib64 directory of your nvcc 11.6 cuda toolkit.

A mismatch between the LD_LIBRARY_PATH searching and the provided compiler has been the only way I can reproduce this failure.

@umiswing does @robertmaynard's solution of repointing LD_LIBRARY_PATH fix your issue? If so, #11787 should resolve this problem once it's merged.

So sorry to reply so late!!! @robertmaynard 's solution fixes my issue. Thank you very much.

Great thank you for confirming @umiswing.
