Legacy ImageMagick Discussions Archive

Hello,

I'm maintaining the ImageMagick package as part of the OpenCSW project for Solaris.
I've noticed the latest update, 6.8.8-2, has bumped the soname number by one:
As this is a very inconvenient change for all dependencies on those libraries, and a bit surprising for such a minor update, I would like to make sure that this was by design?

Thanks in advance,

Laurent

We changed a method signature from float to double to provide for more precision which required an SO bump. Technically it did not require a version bump since it was a private method in magick/fx-private.h, however, there is some small possibility that someone somewhere was using the private method FxEvaluateExpression() and without the version bump, bad things could happen.

Okay, thanks for the explanation

So technically, I could assume the risk of keeping it at the current soname number until 7 is released.

Correct. A SO bump is not necessary for a method signature change in a private header, however, as a courtesy to the user community we made the bump. ImageMagick version 7 avoid these problems by declaring methods public or private with GCC attributes.
