Memory/warning issues
Posted: 2012-06-20T10:28:05-07:00
Hi,
I have used the VisualMagic workspace generator to create a static multithreaded version of the ImageMagick library (the solution name is VisualStaticMT). I am able to successfully build the library. When I link this library against my projects, I get a couple of warnings along the lines of:
LINK : warning LNK4049: locally defined symbol "_xmlFree" imported (LNK4049: The symbol was both exported from and imported to the program)
To resolve this, I added the following preprocessor define to the CORE_coders project:
LIBXML_STATIC
Secondly, when I run my program via the default memory leak detection provided by Visual Leak Detector http://vld.codeplex.com/ a number of leaks are shown within ImageMagick. In order to resolve this I added the following code to the end of the LocaleComponentTerminus function:
It would be beneficial from my point of view, if the above changes were made in the ImageMagick source code repository, as it would save me making them each time I download a new version. However I appreciate there maybe some disagreements about whether the above fixes are correct or not.
Finally, I am guessing there maybe a better/more official way of submitting a patch of this nature, however I do not have any more time at the moment to spend looking further into these issues. So I thought at the very least I'd post this information to this forum in the hope someone else would be able to carry on where I left off. My apologies for not being able to do more.
Kind regards,
Steve
