奇怪的libgcov分析错误：版本不匹配

我正在使用Docker容器构建具有G ++和代码覆盖的C ++应用程序（见下文）。一切都很好，直到这里为止。

但是，当我在同一容器中执行程序

docker运行-IT ... Image /bin /bash -c'cd build＆amp;＆amp; Unbuffer -P ./test_runner＆amp;＆amp; ./collect_gcov.sh'

我总是会出现一个错误：

libgcov proporling错误： .gcda：版本不匹配 - 预期9.4（reparter）9.4（a94 ）获得9.3（a94 ）（版本）（A93 ）*

重点是我使用的是一个自我构建docker容器，该容器仅包括G ++ -9版本9.4.0。 GCC和GCOV也是如此。

FROM  ubuntu:20.04

ENV DEBIAN_FRONTEND noninteractive

COPY assets/* /

RUN mv /sources.list /etc/apt/ && \
    mv /localtime /etc && \
    apt update && apt install -y \
      sudo \
      build-essential \
      gcovr \
      lcov \
      cmake \
      git \
      python3

RUN useradd -d /home/jenkins -u 1000 -ms /bin/bash -g root -G sudo -p jenkins jenkins && \
    echo "jenkins ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/jenkins

USER jenkins
ENV HOME /home/jenkins

ENTRYPOINT ["/entrypoint.sh"]

我检查了不同的编译器版本等。但是仍然不知道为什么会发生这种情况。以前有人有类似的问题吗？

最好的问候

I'm building a C++ application with g++ and code coverage using a docker container (see below). Everthing is fine until here.

But when I execute the program in the same container

docker run -it ... image /bin/bash -c 'cd build && unbuffer -p ./test_runner && ./collect_gcov.sh'

I always get an error:

libgcov profiling error: .gcda:Version mismatch - expected 9.4 (release) (A94) got 9.3 (release) (A93)*

The point is I'm using a self build docker container which only includes the g++-9 with version 9.4.0. Same for gcc and gcov.

FROM  ubuntu:20.04

ENV DEBIAN_FRONTEND noninteractive

COPY assets/* /

RUN mv /sources.list /etc/apt/ && \
    mv /localtime /etc && \
    apt update && apt install -y \
      sudo \
      build-essential \
      gcovr \
      lcov \
      cmake \
      git \
      python3

RUN useradd -d /home/jenkins -u 1000 -ms /bin/bash -g root -G sudo -p jenkins jenkins && \
    echo "jenkins ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/jenkins

USER jenkins
ENV HOME /home/jenkins

ENTRYPOINT ["/entrypoint.sh"]

I checked different compiler version etc. But still no clue why this happens. Does anybody had a similar problem before?

Best regards
