This is Liangang, from Intel, working with @hshen14 on INT8 Conv coverage improvement.

版本、环境信息：    1）PaddlePaddle版本：CommitID：25ec6a2c    2）CPU：Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz    3）系统环境：Linux version 3.10.0-693.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 (closed) SMP Tue Aug 22 21:09:27 UTC 2017

• 问题描述：在enable int8 coverage rate 过程中，想通过gcov分析代码覆盖率情况尝试步骤如下： 1）参考 Link http://ce.paddlepaddle.org:8080/viewLog.html?buildId=21110&buildTypeId=PaddlePaddleFramework_TestCoverage_TestCoverage&tab=buildLog&_focus=63#_state=63 的编译选项, 编译出错, 链接中的编译选项如下：

 cmake .. -DCMAKE_BUILD_TYPE=Release -DWITH_DSO=ON -DWITH_DOC=OFF -DWITH_GPU=ON -DWITH_AMD_GPU=OFF -DWITH_DISTRIBUTE=ON -DWITH_MKL=ON -DWITH_NGRAPH=ON -DWITH_AVX=ON -DWITH_GOLANG=OFF -DCUDA_ARCH_NAME=All -DWITH_PYTHON=ON -DCUDNN_ROOT=/usr/ -DWITH_TESTING=ON -DCMAKE_MODULE_PATH=/opt/rocm/hip/cmake -DWITH_FLUID_ONLY=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DWITH_CONTRIB=ON -DWITH_INFERENCE_API_TEST=ON -DINFERENCE_DEMO_INSTALL_DIR=/root/.cache/inference_demo -DWITH_ANAKIN=OFF -DWITH_COVERAGE=ON -DANAKIN_BUILD_FAT_BIN= -DANAKIN_BUILD_CROSS_PLANTFORM= -DPY_VERSION=2.7 -DCMAKE_INSTALL_PREFIX=/paddle/build -DWITH_JEMALLOC=OFF -DWITH_GRPC=ON ，

2）尝试 做了一些修改（不使用GPU, DWITH_DISTRIBUTE=OFF ）后采用如下命令编译正常，此时WITH_COVERAGE=OFF 编译选项如下：

 cmake3 .. -DCMAKE_BUILD_TYPE=Release -DWITH_DSO=ON -DWITH_DOC=OFF -DWITH_GPU=OFF -DWITH_AMD_GPU=OFF -DWITH_DISTRIBUTE=OFF -DWITH_MKL=ON -DWITH_NGRAPH=ON -DWITH_AVX=ON -DWITH_GOLANG=OFF -DCUDA_ARCH_NAME=All -DWITH_PYTHON=ON  -DWITH_TESTING=ON  -DWITH_FLUID_ONLY=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DWITH_CONTRIB=ON -DWITH_INFERENCE_API_TEST=ON  -DWITH_ANAKIN=OFF -DWITH_COVERAGE=OFF -DANAKIN_BUILD_FAT_BIN= -DANAKIN_BUILD_CROSS_PLANTFORM= -DPY_VERSION=2.7 -DCMAKE_INSTALL_PREFIX=./tmp -DWITH_JEMALLOC=OFF -DWITH_GRPC=ON

3）与 步骤 2）的cmake命令相比，只打开WITH_COVERAGE=ON选项之后，产生编译错误，编译选项如下：

cmake3 .. -DCMAKE_BUILD_TYPE=Release -DWITH_DSO=ON -DWITH_DOC=OFF -DWITH_GPU=OFF -DWITH_AMD_GPU=OFF -DWITH_DISTRIBUTE=OFF -DWITH_MKL=ON -DWITH_NGRAPH=ON -DWITH_AVX=ON -DWITH_GOLANG=OFF -DCUDA_ARCH_NAME=All -DWITH_PYTHON=ON  -DWITH_TESTING=ON  -DWITH_FLUID_ONLY=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DWITH_CONTRIB=ON -DWITH_INFERENCE_API_TEST=ON  -DWITH_ANAKIN=OFF -DWITH_COVERAGE=ON -DANAKIN_BUILD_FAT_BIN= -DANAKIN_BUILD_CROSS_PLANTFORM= -DPY_VERSION=2.7 -DCMAKE_INSTALL_PREFIX=./tmp -DWITH_JEMALLOC=OFF -DWITH_GRPC=ON

报错信息如下：

libdata_layout_transform.a(data_layout_transform.cc.o): In function `paddle::framework::ToMKLDNNDataType(paddle::framework::proto::VarType_Type)':
Paddle/paddle/fluid/framework/data_layout_transform.h:59: undefined reference to `paddle::framework::DataTypeTrait<float>::DataType'
