無法從Windows批處理腳本構建C程序

Question

我想使用Windows批處理腳本構建C程序，但是編譯器出現致命錯誤。

我有一台Windows 10計算機並使用Microsoft C / C ++編譯器。

我正在運行的批處理腳本稱為build.bat ，內容為：

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

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

Answer 1

似乎路徑C:\\Users\\Andrea Nardi\\Documents\\C project\\中的空格引起了您的問題。

通常，在項目路徑中避免使用空格，這將是各種陷阱的原因，因為空格是命令行參數定界符。

使用相對路徑也要簡單得多，這樣您就可以從任何地方（而不是非常特定的文件夾）構建項目，並避免空格。 在這種情況下，類似：

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
