C:LINK.EXE从Makefile失败,但不是从命令行失败

当我尝试从makefile链接时,出现以下错误:

LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'.

Makefile执行:

C:\Users\snmcdonald\Desktop\winMake2\winMake2>nmake "_DEBUG=" /f win2.mk build

NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio 10.0\VC\BI

Stop.

但是,如果我重新运行失败的完全相同的行并从控制台链接,我获得了成功的构建。我使用的是从我的make文件生成的完全相同的libobj

控制台执行:

C:\Users\snmcdonald\Desktop\winMake2\winMake2>link Debug\main.obj Debug\lib.lib /o
ut:Debug\main.exe
Microsoft (R) Incremental Linker Version 10.00.30319.01

main.obj : warning LNK4075: ignoring '/EDITANDCONTINUE' due to '/OPT:ICF' specif
ication

C:\Users\SHANEM~1\Desktop\winMake2\winMake2>debug\main.exe
print from lib

我已将makefile包含在内以供参考。

生成文件

!ifdef _DEBUG
CC = cl
CFLAGS = /c /ZI
FILES = *.c 
OUT = /Fo"Debug\\" /Fe"Debug\\"
LINKOUT = /out:Debug
DIR = Debug
!else
CC = cl
CFLAGS = /O2
FILES = *.c 
OUT = /Fo"Release\\" /Fe"Release\\"
LINKOUT = /out:Release
DIR = Release
!endif

LIB = lib
LINK = link

RM = del
RMFLAGS = *.ojb *.exe 2>NUL

build: main.exe

clean:
    $(RM) $(RMFLAGS)

rebuild: clean build

main.exe: main.obj lib.lib
    $(LINK) $(DIR)\main.obj $(DIR)\lib.lib $(LINKOUT)\main.exe

lib.lib: lib.obj
    $(LIB) $(DIR)\lib.obj $(LINKOUT)\lib.lib

main.obj: 
    $(CC) $(CFLAGS) $(OUT) main.c

lib.obj:
    $(CC) $(CFLAGS) $(OUT) lib.c

测试

我已经在Visual C版本9和版本10上测试了这个。我很困惑为什么它会在我的makefile上失败但在手动输入命令行时成功运行。

解决方案:

nmake /E /f win2.mk build

/ E - 用环境路径覆盖宏变量。

2 个答案:

答案 0 :(得分:5)

  

LIB = lib

搞砸了LIB环境变量。是的,/ E会修复它,但是你的下一个实际需要lib.exe的项目将会失败。选择另一个名称,win32.mak使用“implib”。

答案 1 :(得分:0)

该文件应该存在于 ... \ Microsoft Visual Studio 8 \ VC \ lib

可能是环境变量设置的差异。从命令行手动运行时,检查环境变量设置是什么。

LIB环境变量应该   包含各种lib的路径   目录。你也可以运行   VCVARS32.BAT文件,将会   自动设置环境   为了你。如果你做了很多命令   线构建,我建议创建一个   调用上述的快捷方式   提到了VSVARS32.BAT
