[solved]successful build/compile using GCC/Ubuntu and Windows VS2015 CMD Prompt. but cant get IDE to build. Code::BLocks

[josephaaroncampbell]

Hello,

So i can say I was successful in building/compiling a MagickWand script with VisualStudio 2015 Native Tools x64 Command Prompt as well as through the terminal in Ubuntu using gcc.

The GCC code from the MagickWand example page :http://www.imagemagick.org/script/magick-wand.php

Code: Select all

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

Can be converted to windows command line syntax as : (*must be entered into the VS2015 Native Tools CMD Prompt. Not the normal CMD.exe)

Code: Select all

cl -Fo:WandConvert /I C:\ImageMagick-7.0.2-2\ImageMagick wandTest.c /Link C:\ImageMagick-7.0.2-2\VisualMagick\lib\CORE_DB_MagickWand_.lib 

Maybe someone knows a better way to do it using this method but this works with out any errors.

However, what i will continue to try to figure out is that I cant get a basic MagickWand script to build in an IDE. I am using Code::Blocks because it is cross platform windows/ubuntu and on both OS's I get the same errors. I believe it has to do with properly linking the header and lib files.

Does anyone have any sources for properly setting up your environment when using MagickWand and an IDE ?

Thank You for your time.




My MagickWand code in file "wandTest.c":

Code: Select all

#include "MagickWand/MagickWand.h"

int main(int argc, char *argv[])
{
    MagickWand *newWand;

    MagickWandGenesis();

    newWand = NewMagickWand();

	MagickReadImage(newWand, "target.tif" );

	MagickWriteImage(newWand, "target.jpg" );

	if(newWand) DestroyMagickWand(newWand);

	void MagickWandTerminus(void);

	return 0;
}

In Code::Blocks I have the directory paths for the MagickWand headers and the 'Lib' directory defined in the 'Project -> Build Options -> Search Directories -> Compiler and Link options (respectively) so the compiler will search for the files in those locations. but I get these errors:

So I randomly tried something I tried earlier today from this resource on the code::blocks wiki that gave details about third party #include files:
http://wiki.codeblocks.org/index.php/FA ... ty_libs.3F

I needed to also goto Project -> Build Options -> Linker Settings : and then add BOTH the '.so' library files for MagickWand and MagickCore. Doing this the program compiles with no errors. Earlier I only added the MagickWand '.so' library and it didnt work.

If anyone knows of any explanations or other resources for setting up the best environment for MagickWand I am still learning and could use that info.

Thank You.
