Re: [Plplot-general] Problem building 5.11 on Windows 8.1

[Arjen M. <Arj...@de...>]

Hi Walt,



I am trying this myself - using the comprehensive tests script under MSYS - and I ran into the same issue. It seems that the logic for including the header file unistd.h is incomplete or incorrect as far as MinGW is concerned. I have changed this in my own repository to:



#include "plConfig.h"
#if !PL_HAVE_UNISTD_H
  #define F_OK    1
  #include <stdio.h>
int access( char *filename, int flag )


and that is doing the trick as far as the build up to now is concerned. If successful, I will contribute this.



Regards,



Arjen

I have the TDM version of MinGW installed.

C:\Users\Walt>gfortran --version
GNU Fortran (tdm64-1) 5.1.0
Copyright (C) 2015 Free Software Foundation, Inc.

I downloaded 5.11.0 using git and built with the following
(all one line, of course):

cmake -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=install
-DBUILD_SHARED_LIBS=OFF -DDEFAULT_NO_BINDINGS=ON -DENABLE_cxx=ON
-DENABLE_f95=ON -DDEFAULT_ALL_DEVICES=ON ../plplot.git

[Something different: I got a lot more devices and drivers.]

Make produces the following:

To me, the first one (access) looks like a conflict between gcc and plplot.
The second (isfinite) is a conflict between two things in Plplot???

Help please?  Thanks.
