5. Building the AppImage Executable
Navigate to the HOPR repository and create a build directory
mkdir build && cd build
and compile HOPR using the following cmake flags
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
and then
make install DESTDIR=AppDir
Then create an AppImage (and subsequent paths) directory in the build folder
mkdir -p AppDir/usr/share/icons/
and copy the HOPR logo into the icons directory
cp ../docs/Meshformat/pics/HOPR_logo.png AppDir/usr/share/icons/hopr.png
A desktop file should already exist in the top-level directory containing
[Desktop Entry]
Type=Application
Name=hopr
Exec=hopr
Comment=Tool create .h5 hopr meshes to be read by piclas, flexi, fluxo, etc.
Icon=hopr
Categories=Development;
Terminal=true
Next, download the AppImage executable and run
./linuxdeploy-x86_64.AppImage --appdir AppDir --output appimage --desktop-file=../hopr.desktop
If an error is encountered, see the Section Troubleshooting section for a possible solution. The executable should be created in the top-level directory, e.g.,
hopr-2de94ad-x86_64.AppImage
6. Troubleshooting
This section collects typical errors that are encountered when trying to build the AppImage.
6.1. dlopen(): error loading libfuse.so.2
If the error
dlopen(): error loading libfuse.so.2
AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE
for more information
is encountered, this might be due to a missing fuse installation. On Debian/Ubuntu systems, simply run
sudo apt install libfuse2
