linux - makefile 错误 *** 缺少分隔符。停止

Question

谁能指出生成文件问题的根本原因和修复方法？在 Suse 12 SP2 x64 上构建时出现此错误:

tony@linux-31cz:~/sandbox> gmake -f gnumake.sys
gnumake.sys:18: *** missing separator.  Stop.
tony@linux-31cz:~/sandbox> 

我有这个 make 版本:

tony@linux-31cz:~/sandbox> make --version

下面是 gnumake.sys，其中 [TAB] 是一个制表符。

Answer 1

在给定的示例中使用了错误的语法。正确的语法是这样的:

#-----------------------------------------------------------------------#
#     Common definitions, can be overridden in Platform specific part
#-----------------------------------------------------------------------#
CC                = cc
CCPP              = CC
LIB               = ar rv
CP                = cp
RM                = rm -f
MV                = mv -f
TOUCH             = touch
NEEDMOVE          =
CPP_NEED_C_SUFFIX =
GREP_SEARCH       = "^\# .* .*\.[ch]"
AWK_COLUMN        = $$3
AWK_COLUMN_CPP    = $$3
WD               := $(shell pwd)

ifeq ($(BUILD_PRODUCT_VERSION), 712)
        export BUILDFLAGVER = -DBUILD_PRODUCT_V712
        export TSMVERSIONTXT = 7.1.2.0
        ifeq ($(VERSION_BASED_OUTPUT), 1)
                export TSMVERSION=$(BUILD_PRODUCT_VERSION)
        endif
else ifeq ($(BUILD_PRODUCT_VERSION), 812)
        export BUILDFLAGVER = -DBUILD_PRODUCT_V713
        export TSMVERSIONTXT = 7.1.3.0
        ifeq ($(VERSION_BASED_OUTPUT), 1)
                export TSMVERSION=$(BUILD_PRODUCT_VERSION)
        endif
endif
