Issue with libpng12.0.dylib when using LateX Formula Effect

[bluefloyd]

I don't know if this is actually a bug, and since I already found a solution, I posted this issue in the forum:

http://www.inkscapeforum.com/viewtopic.php?f=29&t=1499

As you can see there, the libpng12.0.dylib which comes with the Mac version of Inkscape 0.46 seems to be outdated. Perhaps someone could bundle a more recent version with the application package.

Cheers

Could you try a recent prerelease build from <http://sourceforge.net/projects/inkscape/files/> if you still get the error messages regarding an outdated libpngxx.x.dylib?

I just downloaded the Inkscape 0.47-pre1.2 Leopard image and I don't get an error message anymore. The "Render -> LaTeX formula" effect is working fine out of the box.

I noted that it is still not possible to re-edit a LaTeX formula created with this built-in effect, in contrast to the TeX Text plugin. Are there plans for providing this feature?

There are other bugs concerning LaTex <https://bugs.launchpad.net/inkscape/+bugs?field.searchtext=LaTeX&search=Search> to be found - maybe you could spare some time and search if it's already reported? I don't use it and haven't installed any of the necessary helper applications, so I can't test the extension myself.

I propose to close this osx-specific bug as 'fixed' and (if nothing similar can be found in the bug database) to file a separate report concerning the LaTex render extension itself.

Thank you for testing the prerelase build and reporting back!

I agree on closing this bug as 'fixed'. Further, for me, the built-in LaTeX render extension is not so important, since I use the Tex text plugin anyway.

Recent prerelease packages for OS X include newer versions of several libraries, fixing the problem with the conflicting libpng versions.

Bug #392693 tracks the underlying issue: quoting Michael Wybrow
"This is an unfortunate consequence of using DYLD_LIBRARY_PATH, when Apple's system libraries have dependencies on libraries that might also be provided by Macports and bundled with Inkscape.

The right way to fix this is to further investigate and fix the problems with rewriting the install-names for all the libraries bundled with Inkscape, so that DYLD_LIBRARY_PATH is not required."
