64-bit Buster

Thanks for providing this AppImage.

 $ uname -a

Could you add a build for 64-bit raspberry os?

Ended up compiling a backport of libcgal-dev_5.1.1 to buster/arm64. prusa-slicer 2.3.0 compiles and runs fine with that.

Recipe: Following the procedure on Debian Wiki:

sudo apt-get install packaging-dev debian-keyring devscripts equivs

Add "deb-src http://deb.debian.org/debian/ testing main" to /etc/apt/sources.conf

sudo apt update
sudo apt source libcgal-dev/testing
cd cgal-5.1/
sudo  mk-build-deps --install --remove
dch --bpo
fakeroot debian/rules binary

Remove "deb-src http://deb.debian.org/debian/ testing main" from /etc/apt/sources.conf

Install backported libcgal-dev package

cd ..
sudo dpkg -i ./libcgal-dev_5.1-1~bpo10+1_arm64.deb

OK. Thank you for your 64-bit prusa-slicer AppImage.

I've done a clean install of 2020-08-20-raspios-buster-arm64, downloaded the AppImage, and done a

sudo apt-get install -y git cmake libboost-dev libboost-regex-dev libboost-filesystem-dev \
> libboost-thread-dev libboost-log-dev libboost-locale-dev libcurl4-openssl-dev libwxgtk3.0-dev \
> build-essential pkg-config libtbb-dev zlib1g-dev libcereal-dev libeigen3-dev libnlopt-cxx-dev \
> libudev-dev libopenvdb-dev libboost-iostreams-dev libnlopt-dev libdbus-1-dev

Starting the AppImage gives the following error message:

prusa-slicer: error while loading shared libraries: libgmpxx.so.4: cannot open shared object file: No such file or directory

so I do an additional

sudo apt-get install libgmpxx4ldbl

Trying again:

$ ./PrusaSlicer-2.3.0-alpha3-arm64.AppImage

I'm not certain what happens. I've done the following:

So I'm wondering whether AppRun

• finds the correct prusa-slicer binary?
• finds all shared libraries needed to run the binary?

I've got the feeling we're on the right track; but we're not there yet. Again thanks for the effort so far.

Hello!

Apologies for not leaving a note when the amd64 AppImage was generated, I believe I had just missed the update to this issue by a few minutes!

I also ran into your latter issue after building the AppImage. Can you try running mkdir /home/pi/Downloads/prusa-slicer? Based on this line: PrusaSlicer GUI initialization failed: boost::filesystem::canonical: No such file or directory: "/home/pi/Downloads/prusa-slicer"

Hi David. Did a mkdir /home/pi/Downloads/prusa-slicer. Now runs. Slices. Good one.
