gcov 命令在 github 管道上返回 -11，但在本地计算机上运行良好

Question

我正在尝试为我的 C++ 项目设置代码覆盖率构建，但无法让它作为 github 工作流程管道工作。完全相同的脚本（我认为）可以在我的本地计算机上运行。这可能是只有其他人才能发现的明显问题之一（我对 github 管道还是新手），所以我很抱歉问这个问题。

我确实设置了一个虚拟存储库来显示问题。它位于这里。我在本地计算机上尝试的脚本是：

git clone [email protected]:yobeonline/gcov_test.git
cd gcov_test/
export CXXFLAGS="--coverage -fprofile-abs-path -g -O0"
export CFLAGS="--coverage -fprofile-abs-path -g -O0"
export LDFLAGS="--coverage"
cmake -S . -B build
cmake --build build
./build/main
mkdir build/html
gcovr --gcov-executable /usr/bin/gcov --print-summary -x build/coverage.xml --html-details build/html/index.html -r . build

我得到的输出正是我所期望的：

lines: 10.0% (2 out of 20)
functions: 33.3% (1 out of 3)
branches: 0.0% (0 out of 0)
calls: 0.0% (0 out of 0)

github pipeline 给出（详细）（参见here）

当本地运行事物和在操作中运行事物之间的行为时，有时是由于两个环境中的版本不同所致。

我会在工作流程中添加几行来显示所使用的 gcc 和 gcov 的版本，然后在本地尝试使用相同的版本（如果不同）。
