当我尝试从 makefile 链接时,出现以下错误:
LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'.
生成文件执行:

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,我将获得成功的构建。我使用的是完全相同的lib
,并且obj
是从我的 make 文件中生成的。
控制台执行:
C:\Users\snmcdonald\Desktop\winMake2\winMake2>link Debug\main.obj Debug\lib.lib /o
ut:Debug\main.exe

print from lib
我已经包含了我的 makefile 以供参考。

测试
我已经在 Visual C 版本 9 和版本 10 上对此进行了测试。我很困惑为什么它会在我的 makefile 上失败,但在命令行上手动输入时会成功运行。
解决方案:
nmake /E /f win2.mk build
/E - 使用环境路径覆盖宏变量。
