CMAKE安装Plplot

wdy

大家有用fortran画图吗？
下面是一种解决方案，用到的软件是Plplot，但是需要先安装Cmake，安装过程中出错。


将ENABLE_fortran之前的勾去掉，就可以成功generate

然而我要用的就是fortran啊~

按照搜索到的一些解决办法，觉得是编译器的选择问题，具体如下



用的是intel visual fortran 2013，win10系统，
在Compilers->Fortran下寻找编译器，在ivf的安装目录下没找到编译器，该如何解决呢？

下面这段是从Plplot源目录bindings\fortran\Cmakelists.txt文件中摘录的：

if(ENABLE_fortran)

将Plplot版本换成5.10.0就可以顺利generate了，看来是版本的问题

下面这段是从Plplot源目录bindings\fortran\Cmakelists.txt文件中摘录的：

if(ENABLE_fortran)

if(CMAKE_Fortran_COMPILER MATCHES "gfortran")
    message (STATUS
      "WARNING concerning spurious warning messages generated by the gfortran compiler.
   The new Fortran binding is known to generate some ~50 \"marked
   PRIVATE\" warning messages when building the plplotfortran target with the
   gfortran Fortran compiler.  A typical example of such a warning
   message is

   Warning: Symbol 'interface_plcont' at (1) is marked PRIVATE but has been given the binding label 'c_plcont'

   It appears these warnings (which do not occur if using the ifort or
   nagfor Fortran compilers) are due to a gfortran bug (see
   <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49111> and
   <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64861>), i.e., they
   are spurious warnings concerning completely valid use of the
   private attribute for interface blocks describing C routines.
   There appear to be no known negative consequences of this gfortran
   bug other than the spurious warnings themselves.  Until this gfortran
   bug is fixed, these ~50 \"marked PRIVATE\" warnings should just be
   ignored for those using gfortran."

这段代码似乎是针对gfortran编译器的，接下来提到的ivf也是包含在if(win32)条件语句中，是不是只能用32位的编译器？下载的Plplot版本是最新的5.13.0，不应该是这样的啊~~！
