Subject"This copy of gnuplot cannot read png/gif/jpeg images" problem
Message-ID<8f17c8c2-3703-4eb9-ba8b-907cd50127e1@googlegroups.com>
Hello, I am in charge of installing and maintaining gnuplot on our clusters and am by no means an expert.  Our user has reported the following is occurring: 

gnuplot> plot 'test.png' binary filetype=png with rgbimage
         This copy of gnuplot cannot read png/gif/jpeg images


After googling a bit, I have looked in the build log for PNG entrails and see the following: 


checking for gdlib-config... /usr/bin/gdlib-config
checking for gdImageCreateTrueColor in -lgd... yes
checking gd.h usability... yes
checking gd.h presence... yes
checking for gd.h... yes
checking for gdImageGif in -lgd... yes
checking for gdImageGifAnimBegin in -lgd... yes
checking for gdImageJpeg in -lgd... yes
checking for gdImageStringFT in -lgd... yes
checking for gdImagePng in -lgd... yes

...

  jpeg terminal: yes
  gif terminal: yes (with animated gif)
  png terminal: yes
    (jpeg, gif and png terminals can use TTF fonts)
  pdf terminal: no (requires libpdf)
...

  cairo-based pdf and png terminals: yes 



I don';t understand why gnuplot thinks it cannot handle png files.  Can someone help me debug this one?  
Thanks.

One more datapoint: 

gnuplot> show datafile binary filetypes

        This version of gnuplot understands the following binary file types:
          avs     bin     edf     ehf     gif     gpbin   jpeg    jpg     png    raw      rgb     auto

That seems odd.  Please report the output from
  gnuplot -e "show version long"

There should be an entry  +GD_PNG
If this is present then it indicates that indeed the program should
be able to read png files.  If it's missing then I guess something
must have gone wrong with the configure+build at a later stage after
it had already reported that it was going to include png support.
You might have a look in config.log for error messages that mention
libgd. But really the info you show is self-contradictory so I
don't have a good guess at what could be wrong.

The output seems confusing.  There is no +GD_PNG.  But there is -LIBGD.  I'm not sure where in the config.log or build process it decided to disable the PNG support.

I also see this in config.log:  

GDLIB_CONFIG='/usr/bin/gdlib-config'

And so I tried this: 

rcook@rzgpu2 (dpkg-mkdeb.GMTn7fiHG9): /usr/bin/gdlib-config --features
GD_XPM GD_JPEG GD_FONTCONFIG GD_FREETYPE GD_PNG GD_GIF GD_GIFANIM GD_OPENPOLYGON

So the libgd that gnuplot is using has PNG support, I think.

perhaps can someone who is NOT having this problem send me their build output and config.log and config.status?  
thanks

The minus sign indicates libgd support is missing.

Not just PNG.  It's apparently failed to include libgd at all.
There should be a clue in config.log

Thank you.  I believe I have found the problem.  Our build system occurs on a server farm and I was not loading the GD libraries into the RPM repo there.

Hello Rich,

some years ago i had problems using the system libgd together with gnuplot.
i solved this  by downloading/compiling my own libgd 
and run gnuplot configure with 

--with-gd=/opt/gd-2.0.35

In my config.log i can find these line  related to libgd:
TERMLIBS=' -lreadline  -lncurses  -lz -lgd -lXpm -lX11 -ljpeg -lfontconfig -lfreetype -lpng12 -lz -lm -ljpeg -lfreetype -lpng'
