make failed to product int4_offline executable

[XiaotaoChen]

I am to product int4_offline with instructions as blows:
build loadgen it seems successful.

git clone --recurse-submodules https://github.com/mlperf/inference.git mlperf_inference

LOADGEN_DIR=<Path> (e.g. ${PWD}/mlperf_inference/inference/loadgen)
CUDA_PATH=<Path for CUDA toolkit e.g. /usr/local/cuda-10.1>
cd $LOADGEN_ DIR
CFLAGS="-std=c++14 -O3" python setup.py bdist_wheel

And then to product int4_offline as belows:

#!/bin/bash
LOADGEN_DIR='/mnt/truenas/upload/xiaotao.chen/Repositories/mlperf_inference/loadgen'
CUDA_PATH='/usr/local/cuda'
make -j CUDA=${CUDA_PATH} LOADGEN_PATH=${LOADGEN_DIR} clean
make -j CUDA=${CUDA_PATH} LOADGEN_PATH=${LOADGEN_DIR} all

the error info

it tells undefined reference to std::thread::_M_start_thread , seems like gcc version is mismatch between my host and int4_offline.a used. my version as belows:

Can you tells the detail version int4_offline.a used. How can i produce int4_offline ? thanks @psyhtest

[XiaotaoChen]

it can build successfully when i switch gcc version to 5.5 as belows:

gcc (Ubuntu 5.5.0-12ubuntu1~16.04) 5.5.0 20171010

@XiaotaoChen Sorry, I'm not familiar with int4_offline. I assume it's a build product from NVIDIA's submission?

/cc @nvpohanh

Hi @XiaotaoChen , we only tested on the gcc version installed in the docker container. As you found out, it does not support older versions of gcc.

[XiaotaoChen]

@nvpohanh Thanks for your reminding.

@XiaotaoChen Does gcc version fix your problem? If so, please close this issue. Thanks
