Question

我想按照http://sunsite.ualberta.ca/Documentation/Gnu/make-3.79/html_chapter/make_7.html#SEC72中的指南在Makefile中编写一些条件。但是，我收到错误Makefile:219: *** missing separator. Stop.，其中第219行是ifeq语句的行。 -$(FC)的三行以标签开头。

我正在使用GNU Make 3.81。非常感谢任何帮助！

[...]

mod: $(MODBIN)

$(MODBIN): $(MODSRC)
ifeq($(FC),gfortran)
    -$(FC) $(MODFLAGS) -J$(INCPATH) $(INCLUDE) -c -o $@ $(subst $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
else ifeq($(FC),ifort)
    -$(FC) $(MODFLAGS) -module $(INCPATH) $(INCLUDE) -c -o $@ $(subst $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
else ifeq ($(FC),xlf2003_r)
    -$(FC) $(MODFLAGS) -qmoddir=$(INCPATH) $(INCLUDE) -c -o $@ $(subst $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
endif

io: $(IOBIN)

编辑：根据@ sagar-sakre的建议，我改为：

[...]
mod: $(MODBIN)

$(MODBIN): $(MODSRC)
    ifeq($(B3dC),gfortran)
    -$(FC) $(MODFLAGS) -J$(INCPATH) $(INCLUDE) -c -o $@ $(subst $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
    else ifeq($(B3dC),ifort)
    -$(FC) $(MODFLAGS) -module $(INCPATH) $(INCLUDE) -c -o $@ $(subst $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
    else ifeq ($(B3dC),xlf2003_r)
    -$(FC) $(MODFLAGS) -qmoddir=$(INCPATH) $(INCLUDE) -c -o $@ $(subst $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
    endif endif endif

io: $(IOBIN)
[...]

但是，现在我收到了这个错误：

ifeq(xlf,gfortran)
/bin/sh: -c: line 0: syntax error near unexpected token `xlf,gfortran'
/bin/sh: -c: line 0: `ifeq(xlf,gfortran)'
make: *** [build/basic.o] Error 2

所以这里仍有问题......

ifeq之后应该有[空格]

mod: $(MODBIN)
$(MODBIN): $(MODSRC)
ifeq ($(FC),gfortran)
    -$(FC) $(MODFLAGS) -J$(INCPATH) $(INCLUDE) -c -o $@ $(subst
    $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
else ifeq ($(FC),ifort)
    -$(FC) $(MODFLAGS) -module $(INCPATH) $(INCLUDE) -c -o $@ $(subst
    $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
else ifeq ($(FC),xlf2003_r)
     -$(FC) $(MODFLAGS) -qmoddir=$(INCPATH) $(INCLUDE) -c -o $@ $(subst 
     $(BUILDPATH),$(MODPATH),$*).f90 $(NETCDFLDFLAGS)
endif

General Makefile将是

target:dependencies
ifeq ( parm1, parm2)
 [TAB]   operation
else
 [TAB]   operation
endif

Makefile中的条件：丢失分隔符错误？
