Magick++ attribute will not link

[Necuima]

I am trying to get the exif data from a jpeg image file using the Magick++ attribute approach but I get link errors LNK2028 and LNK2019 for the image object instance attribute. The environment is Visual Studio Community Edition 2017. The version of ImageMagick is 6.9.3-7 compiled with the Magick++ headers. The operating system is Windows 10. I get the same issue when trying to use the latest Windows version of Image Magick similarly compiled.

The exif data are there via the Windows command line indentify -verbose filename.

The Magick++ methods that I am using such as read, quality, resize and write all link and work fine but the attribute does not - (standard string) extracted_data = image.attribute("exif:DateTime"); gives the link errors.

Any advice will be most appreciated and thanking you in anticipation.

Further information: On a separate Windows 7 PC the identical C++ code compiles, links and executes perfectly. On that PC the IDE is Visual Studio 2010 Express with ImageMagick 6.8.6.

The issue turned out to be due to conflicting versions of ImageMagick on the one PC. And make sure that MAGICK_CORE is set correctly in the environment variables. Once I had that sorted out the program compiled, linked and executed OK.
