无法从 Windows 批处理脚本构建 C 程序

Question

我想使用 Windows 批处理脚本构建 C 程序，但编译器出现 fatal error 。

我有一台 Windows 10 计算机并使用 Microsoft C/C++ 编译器。

我正在运行的批处理脚本名为build.bat，内容为:

SET PROJECT_COMPILER=cl

SET HOME_DIRECTORY=%~dp0
SET PROJECT_SRC=%HOME_DIRECTORY%src\
SET PROJECT_BIN=%HOME_DIRECTORY%bin\
SET PROJECT_INCLUDE=%HOME_DIRECTORY%include\

%PROJECT_COMPILER% "%PROJECT_SRC%*.c" /I"%PROJECT_INCLUDE%" /link 
/out:"%PROJECT_BIN%out.exe"

del /f .\*.obj

以及我从行 %PROJECT_COMPILER% "%PROJECT_SRC%*.c"/I"%PROJECT_INCLUDE%"/link/out:"%PROJECT_BIN%out.exe" 得到的输出是:

C:\Users\Andrea Nardi\Documents\C project\test_project>cl "C:\Users\Andrea Nardi\Documents\C project\test_project\src\*.c"         
/I"C:\Users\Andrea Nardi\Documents\C project\test_project\include\" /link 
/out:"C:\Users\Andrea Nardi\Documents\C project\test_project\bin\out.exe"

路径 C:\Users\Andrea Nardi\Documents\C project\ 中的空格似乎导致了您的问题。

一般来说，避免在项目路径中出现空格，由于空格是命令行参数分隔符，这将导致各种陷阱。

使用相对路径也更加简单，这样您就可以从任何地方而不是非常特定的文件夹构建项目，并避免空格。在这种情况下，类似于:

SET PROJECT_COMPILER=cl

REM Set working directory to that of this batch file
pushd %~dp0

REM Set paths relative to batch file path
SET PROJECT_SRC=.\src
SET PROJECT_BIN=.\bin
SET PROJECT_INCLUDE=.\include

REM Build...
%PROJECT_COMPILER% "%PROJECT_SRC%\*.c" /I"%PROJECT_INCLUDE%" /link 
/out:"%PROJECT_BIN%\out.exe"

REM  Clean-up...
del /f .\*.obj

REM Restore original working directory
