Here's a patch: Source: Apply with prepare() { cd ${pkgname}-${pkgver}-${pkgrel}.orig patch -p1 < "$srcdir"/fixWriteLog.diff } If you add me to co-maintainers, I can push it.

Hm, I'm listed as the submitter, but I can't push to ssh:// git-receive-pack: permission denied: haagch fatal: Could not read from remote repository. Oh well...

Current PKGBUILD is missing a dependency, opencl-headers. Here is the error message: In file included from ../src/Render3D.h:19:0, from ../src/Render3D.cpp:30: ../src/cl_support.hpp:25:21: fatal error: CL/cl.hpp: No such file or directory compilation terminated. src/ recipe for target 'src/Render3D.o' failed This patch resolves it for me: --- PKGBUILD.old 2016-03-03 13:11:23.053661591 -0500 +++ PKGBUILD 2016-03-03 13:11:34.043867457 -0500 @@ -7,7 +7,7 @@ arch=('any') url="" license=('GPL3') -depends=('libjpeg-turbo' 'ocl-icd' 'gtk2') +depends=('libjpeg-turbo' 'ocl-icd' 'gtk2' 'opencl-headers') provides=('mandelbulber') conflicts=('mandlebulber') source=("${pkgname}::${pkgname}-${pkgver}-${pkgrel}.orig.tar.gz")

Meh, clover still doesn't support it. * -cl-denorms-are-zero still has to be removed * Still something about static, but who cares for that: for i in /usr/share/mandelbulber/cl/*; do sed -i "s/static //g" $i; done But then it's still error: cannot combine with previous 'type-name' declaration specifier A quick google search looks like this sometimes happens when clang can't parse something correctly... I tried a bit around, but the error message is not very clear. I think clang thinks that "half" is already defined, and renaming it gets rid of that error: for i in /usr/share/mandelbulber/cl/*; do sed -i "s/half /halfFOO /g" $i; done for i in /usr/share/mandelbulber/cl/*; do sed -i "s/half)/halfFOO)/g" $i; done Then I get OpenCL Build log: ERROR: ProgramSSAO::build() (-43) And then it segfaults in gobject. Well...

Hey there, thanks for the pkg. In the dependecy-list opencl-headers is missing - it doesn't compile without it.

In the newest version opencl works much better. :)

With radeon gallium opencl (I only tested radeonsi) it currently does not work because the build parameter "-cl-denorms-are-zero" is not supported. It has to be removed from src/cl_support.cpp buildParams = "-w -cl-single-precision-constant -cl-denorms-are-zero "; Then it tries to compile the opencl kernels, but fails: error: OpenCL does not support the 'static' storage class specifier static formulaOut Fractal(__constant sClInConstants *consts, float3 point, sClCalcParams *calcParam); Not sure if this is supposed to be this way or not since I don't know opencl well enough.

Hm, beignet actually compiles with clang 3.4 snapshots now. The tests work but I'm not sure how to use it with mandelbulber. I think you need an "icd" loader or so? With fglrx and switchable graphics it's strange. Either with their official "support" or with running mandelbulber on the intel gpu as root (then you get amd opencl too) I get a black screen with no effects, a pink screen with some effects and a crash with all effects. But it works when directly rendering on fglrx's X server and accessing it with vnc.
