Microsoft nmake:是否可以从shell命令输出中定义宏？

Question

我正在尝试将我的SVN修订信息保存到宏中,同时通过Microsoft Visual Studio的nmake创建我的代码.

在GNU make中,我做了类似的事情:

SVN_REVISION=r$(shell svnversion -n)

所以我得到例如:SVN_REVISION = r10001

这也可以在Microsoft nmake中做到吗？

先感谢您.

使用提到的技术和递归调用make,可以这样做:

!IFNDEF MAKE
MAKE=NMAKE
!ENDIF
!IFNDEF SVN_REVISION
!   IF [echo off && FOR /F "usebackq" %i IN (`svnrevision -n`) DO  SET SVN_REVISION=%i && $(MAKE)      /$(MAKEFLAGS) /nologo /f $(MAKEDIR)\Makefile && exit /b  ] == 0
!     MESSAGE Make completed
!   ELSE
!     ERROR Error in nmake
!   ENDIF
!ELSE
# $(SVN_REVISION) now contains the string returned from the command `svnrevision -n`
!MESSAGE SVN_REVISION is $(SVN_REVISION)
#      Put the parts of the makefile that depend on SVN_REVISION here
!ENDIF
#
# To be a valid makefile it must have some rules to perform
all:
     @echo;$(SVN_REVISION)
