cant compile C program from example. IM 7.0.2 . Ubuntu. Fatal error.

[josephaaroncampbell]

Hello,

I just installed IM from source folowing these instructions:
http://www.imagemagick.org/script/install-source.php

Code: Select all

identify -version

returns:

Version: ImageMagick 7.0.2-2 Q16 x86_64 2016-07-02 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2016 ImageMagick Studio LLC
License: http://www.imagemagick.org/script/license.php
Features: Cipher DPC HDRI OpenMP
Delegates (built-in): bzlib djvu fontconfig freetype gvc jbig jng jpeg lcms lqr lzma openexr png tiff wmf x xml zlib

Everything seems to have gone ok. But when I follow the tutorial for MagickWand here:
http://www.imagemagick.org/script/magick-wand.php

Code: Select all

cc -o wand wand.c `pkg-config --cflags --libs MagickWand`

returns the following error:

wand.c:3:29: fatal error: wand/MagickWand.h: No such file or directory
#include <wand/MagickWand.h>
^
compilation terminated.

My first thought was to update the $PATH variable but I am not having too much luck with that working. I have found it to be similar to this post:
https://www.imagemagick.org/discourse-s ... nd#p127177

So here is my configure info.

Code: Select all

identify -list configure

I dont know if it matters. But i am running a guest Ubuntu 14.04 64bit in VirtualBox v5.0.22 r108108 on host Windows 10 64bit.

I read through the advanced Unix installation info and maybe I need to do something different? I am just at the beginnings of learning C and how to compile programs. So thank you for your time and your patience.

See the V7 porting guide http://www.imagemagick.org/script/porting.php, especially the note about header file directories: MagickWand instead of wand, etc. Also possibly "MagickWand-config" instead of "pkg-config".

[josephaaroncampbell]

thank you! I will check that out.

So the porting guide helped solve the issues. Updating the example code to the v7 header names, function calls, and locations did the trick.

example of updated C program "wandTest.c" :

Code: Select all

#include "MagickWand/MagickWand.h"

int main(int argc, char *argv[])

{
    MagickWand *newWand;

    MagickWandGenesis();

    newWand = NewMagickWand();

    MagickReadImage(newWand, "test.tif" );

    MagickWriteImage(newWand, "test.jpg" );

    if(newWand) DestroyMagickWand(newWand);

    void MagickWandTerminus(void);

    return 0;
}

this compiled and executed with out any errors using:
cc -o wandTest wandTest.c `pkg-config --cflags --libs MagickWand`


Im running Ubuntu 14.04 x64 with IM version 7.0.2-2


Thank You Again for your help.
