[Bug-plotutils] plotutils-2.6 compile errors

[Jack Hancock]

I've today downloaded plotutils-2.6.  There appeared two compile errors from "make". The error text (reproduced herein manually) indicates:

            In file included from /usr/include/png.h:452:0,

                                   from z_write.c:43:

z_write.c: In function '_pl_z_maybe_output_image':

z_write.c:167:22: error: dereferencing pointer to incomplete type

      if ( setjmp ( png_ptr ->jmpbuf))

                                     ^

z_write.c: In function '_our_error_fn_stdio':

z_write.c:447:19: error: dereferencing pointer to incomplete type

      longjmp ( png_ptr ->jmpbuf,1)

                                  ^

make[2]: *** [z_write.lo] Error 1

make[2]: Leaving directory '/home/jhancock/Downloads/plotutils-2.6/libplot'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory '/home/jhancock/Downloads/plotutils-2.6'

make[1]: *** [all] Error 2

 

The file /usr/include/png.h contains the following comments:

/*  png.h - header file for PNG reference library

* 

*  libpng version 1.5.13 - September 27, 2012

*  Copyright (c) 1998 - 2012 Glenn Randers-Perhson

 

The /usr/include/png.h file presumably was bundled within CentOS-7-i386-DVD-1511.iso which I had installed a couple of days ago.
