For those having issues: I'm waiting on the next release of Mandelbulber2 to get this package in a proper state. It is an upstream issue that must be worked around for the time being with the current release. It's fixed in the current source, though, so that's another option if you prefer.

If you're getting the missing directory failure in the build function like cknoblauch, you need to modify the PKGBUILD as the directory structure was changed around (/deploy no longer exists):

This is the error I got from yay:

==> Aborting...

-> error making: mandelbulber2-exit status 4

-> Failed to install the following packages. Manual intervention is required:

Aborting...

-> error making: mandelbulber2-exit status 4

-> Failed to install the following packages. Manual intervention is required:

I will check their git page, but if anyone has a working "Manual intervention", preferably in a form a non developer can follow, it would be in a good place here for others to find.

Build is currently failing with this error:

Seems that this is an issue with Mandelbulber2 itself. An issue has been opened by a community member (thanks @MrBruz!): https://github.com/buddhi1980/mandelbulber2/issues/978

I did my daily system update and my favorite fractal program of all time threw up an error (NOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!! Please say it isn't so!!!:

ERROR: One or more files did not pass the validity check! -> error making: mandelbulber2-exit status 1 -> Failed to install the following packages. Manual intervention is required: mandelbulber2 - exit status 1

so what intervention is needed, and how do I intervene???

Thanks for the suggestion! I've updated libpng12 to libpng and added libtiff on this package and the opencl-git variant that I also maintain.

Is there a reason this depends on libpng12? I've tested it with libpng 1.6.48-1 and it works exactly the same for me as far as I can tell. (Saving with alpha doesn't seem to work, which I presume may be something I'm doing wrong or something I should report upstream, but that particular brokenness is also exactly the same with either libpng or libpng12.) I respectfully suggest updating that dependency to just libpng.

Additionally, I respectfully suggest adding libtiff as a dependency, which will allow this to export tiff images as well. Thank you!

qt5-multimedia should be added as a build dependency

I have an even worse situation: mandelbulber2: error while loading shared libraries: libgslcblas.so.0: cannot open shared object file: No such file or directory
