这个make文件有什么问题？ （错误是：make ***没有规则来制作目标）

Question

我正在尝试在我的Windows 7笔记本电脑上编译和运行XROTOR。我已经下载了Cygwin，以及XROTOR（http://web.mit.edu/drela/Public/web/xrotor/）

来自自述文件......

Build Sequence
--------------
To install, first build the plot library in  ./plotlib  ...

 % cd plotlib
 % make libPlt.a

Then build the programs in  ./bin  ...

 % make xrotor
 % make jplot

当我去“make libPlt.a”时，我收到一条错误消息：

make：* **没有规则来制作目标：'libPlt.a'。停止。

我犯了什么愚蠢的错误？

这是我相信的make文件：

#=======================================#
# Makefile options for Xplot11 library  #
#   Set up or select a set of compile   #
#   options for your system             # 
#=======================================#


# Set library name 
PLTLIB = libPlt_gDP.a

# Some fortrans need trailing underscores in C interface symbols (see Xwin.c)
# This should work for most of the "unix" fortran compilers
DEFINE = -DUNDERSCORE

FC = gfortran
CC  = gcc
DP = -fdefault-real-8

FFLAGS  = -O2 $(DP)
CFLAGS  = -O2 $(DEFINE)
AR = ar r
RANLIB = ranlib 
LINKLIB = -L/usr/X11R6/lib -lX11 

其实！我认为这是makefile（它被称为makefile所以我假设了很多）

更新：我输入“make libPLT_gDP.a”

当我安装Cygwin时，我没有安装X11的东西。故事的道德，确保在安装Cygwin时检查“make”以及所有X11的东西（也可以检查所有的fortran事情（使用搜索））。无论如何，不​​要担心XRotor，而是下载CRotor。看看它的文档，你应该能够弄清楚如何制作。实际上，这里有一些您可能觉得有用的自述文件：

 % cd plotlib
 % make libPlt.a

Then build the programs in  ./bin  ...

 % make xrotor
 % make jplot


Documentation
-------------
User Guide is in the  xrotor.doc  file.  If impatient, you can just
run XROTOR:

 % xrotor
