Segment fault on Deepin 15.11.

[abcfy2]

From https://github.com/TheAssassin/AppImageLauncher/issues/127#issuecomment-553837395

Deepin 15.11 is based on Debian 9, VM can be found here: https://www.osboxes.org/deepin/#deepin-15-11-vbox

I try to build deb from source code, still segment fault.

REPO_ROOT=.
cmake "$REPO_ROOT" -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=RelWithDebInfo $EXTRA_CMAKE_FLAGS -DTRAVIS_BUILD=ON -DBUILD_TESTING=OFF
make -j $(nproc)
cmake .
cpack -V -G DEB

Then install deb package:

sudo apt install -y ./appimagelauncher_2.0.3-local~4f7bc8e_amd64.deb

Still segment fault:

Does this specific AppImage cause a segfault on other systems? Or is it just you assuming the issue is limited to Deepin 15?

Ubuntu 16.04 is working, but Debian 9 is not.

[abcfy2]

I try to install deb on Debian 9.

# Use vagrant to boot up a Debian 9 VM
vagrant init debian/stretch64
vagrant up

# Download from release page
wget https://github.com/TheAssassin/AppImageLauncher/releases/download/v2.0.3/appimagelauncher_2.0.3-travis888.4f7bc8e.xenial_amd64.deb

sudo apt install -y ./appimagelauncher_2.0.3-travis888.4f7bc8e.xenial_amd64.deb
cd ~/Applications

And also, I try to build deb package on Debian 9, still not working.

[TheAssassin]

Can you please provide a link to your AppImage?

[abcfy2]

Sure. https://github.com/abcfy2/qBittorrent-Enhanced-Edition/releases/download/v4.1.9.3/qBittorrent-Enhanced-Edition.AppImage

And the AppImage build script can be found in .travis.yml: https://github.com/abcfy2/qBittorrent-Enhanced-Edition/blob/v4_1_x/.travis.yml

fwiw, this AppImage on Deepin Linux is working fine with appimaged from https://github.com/probonopd/go-appimage/releases/tag/continuous.

[abcfy2]

Yeah, appimaged is working, but appimagelauncher is not.
