make 失败无法停止 shell 脚本

Question

我正在使用 bash 脚本（部分单元测试已在 Code Review 上进行了审查）、cmake 和 make 在最新版本的 Fedora Linux 上自动化个人项目的构建和单元测试。正面测试在构建系统上传递，但是，当我在其中一个单元测试中强制 LD 失败时，构建仍然在更高级别通过。它需要在所有级别都失败。

这是来自 cmake 命令生成的 make 的错误消息：

/home/pacman/Documents/projects/VMWithEditor/VMWithEditor/human_readable_program_format.c:179: multiple definition of `HRF_delete_linked_list_of_program_steps'; CMakeFiles/Run_All_Unit_Tests.exe.dir/home/pacman/Documents/projects/VMWithEditor/VMWithEditor/UnitTests/HRF_UnitTest/HRF_UnitTest/unit_test_human_readable_program_format.c.o:/home/pacman/Documents/projects/VMWithEditor/VMWithEditor/UnitTests/RunAllUnitTests/RunAllUnitTests/../../../human_readable_program_format.c:179: first defined here  
collect2: error: ld returned 1 exit status  
make[2]: *** [CMakeFiles/Run_All_Unit_Tests.exe.dir/build.make:433: Run_All_Unit_Tests.exe] Error 1  
make[2]: Leaving directory '/home/pacman/Documents/projects/VMWithEditor/VMWithEditor/UnitTests/RunAllUnitTests/RunAllUnitTests/Debug'  
make[1]: *** [CMakeFiles/Makefile2:95: CMakeFiles/Run_All_Unit_Tests.exe.dir/all] Error 2  
make[1]: Leaving directory '/home/pacman/Documents/projects/VMWithEditor/VMWithEditor/UnitTests/RunAllUnitTests/RunAllUnitTests/Debug'  
make: *** [Makefile:103: all] Error 2  

这是顶级 shell 脚本的输出，不应执行最后 2 个构建：

Building CommandLine_UnitTest/CommandLine_UnitTest  
Building ControlConsole_UnitTest/ControlConsole_UnitTest  
Building Editor_UnitTest/Editor_UnitTest  
Building HRF_UnitTest/HRF_UnitTest  
Building Parser_Unit_Test/Parser_Unit_Test  
Building RunAllUnitTests/RunAllUnitTests  
Building State_Machine_Unit_Test/State_Machine_Unit_Test  
Building VirtualMachine_UnitTest/VirtualMachine_UnitTest  

这是在应该时不会失败的 shell 脚本：

编译调试文件

#! /bin/sh

# Create a Debug build directory and then build the target within the Debug directory
# Stop on any build errors and stop the parent process.

mkdir Debug
cd Debug
cmake -DCMAKE_BUILD_TYPE=Debug ..
retVal=$?
if [ $retVal -ne 0 ]; then
    echo "\n\ncmake failed $retval!\n\n"
    exit $retVal
fi
make VERBOSE=1
if [ $retVal -ne 0 ]; then
    echo "\n\nmake failed! $retval\n\n"
    exit $retVal
fi

前一个shell脚本被这个shell脚本调用，子目录中有8个前一个shell脚本的实例。

编译所有调试文件

#! /bin/sh

# Build the debug version of all the unit tests
# Stop on any build errors.

for i in *
do
    if [ -d $i ] ; then
        TESTDIRECTORY="$i/$i"
        SHELLFILE="$TESTDIRECTORY/buildDebug.sh";
        if [ -f $SHELLFILE ] ; then
            echo "Building $TESTDIRECTORY";
            cd "$TESTDIRECTORY"
            ./buildDebug.sh >& buildDebuglog.txt
            retVal=$?
            if [ $retVal -ne 0 ]; then
                exit $retVal
            fi
            cd ../..
        fi
    fi
done;

这将生成报告错误的 make 文件：

Answer 1

你有：

make VERBOSE=1
if [ $retVal -ne 0 ]; then

但retVal仍然是cmake命令的返回码。要么重置它，要么$?直接测试。
