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:

==> ERROR: A failure occurred in build().

==> Aborting...

-> error making: mandelbulber2-exit status 4

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

mandelbulber2 - exit status 4

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

Hi, When will Mandelbulber be updated, it has speed advantages?
