Python plugin for linuxdeploy. Sets up miniconda inside an AppDir, and installs user-specified packages.
# get linuxdeploy and linuxdeploy-plugin-conda (see below for more information)
# configure environment variables which control the plugin's behavior
> export CONDA_CHANNELS=mychannel;myotherchannel CONDA_PACKAGES=mypackage;myotherpackage
# call through linuxdeploy
> ./linuxdeploy-x86_64.AppImage --appdir AppDir --plugin conda --output appimage --icon mypackage.png --desktop-file mypackage.desktopThere are many variables available to alter the behavior of the plugin. The current list can be obtained by calling the plugin with --help.
You can cross-build native extensions for i[3-6]86 by installing a 32-bit compiler and instructing distutils to use those.
On Debian, Ubuntu and other derivatives:
sudo apt-get install -y gcc-multilib g -multilib
export ARCH=i386 CC="gcc -m32" CXX="g -m32" LDSHARED="gcc -m32 -shared -pthread"If your system doesn't provide multilib compilers, wrappers like i686-linux-gnu-gcc also work fine.
Note: It's very important to also overwrite LDSHARED!

By default, linuxdeploy-plugin-conda redownloads the miniconda installer on every execution. This is not an issue for most people, as the installers are only 50-80 MiB in size. However, it is usually not necessary to redownload the file every time, especially while developing scripts based on the conda plugin.
Therefore, you can set a custom directory via the environment variable $CONDA_DOWNLOAD_DIR, into which downloaded files are stored then. The plugin makes use of some wget parameters to ensure that the file is only downloaded when it is incomplete (-c) or there is a newer version available (-N).
Example:
> export CONDA_DOWNLOAD_DIR=/my/own/directory
> ./linuxdeploy-x86_64.AppImage --plugin conda [...]
[...]
Using user-specified download directory: /my/own/directory
[...]Relative paths work as well.
This generates a working FreeCAD AppImage from Conda ingredients, including Qt and PyQt:
wget -c "https://raw.githubusercontent.com/TheAssassin/linuxdeploy-plugin-conda/master/linuxdeploy-plugin-conda.sh"
wget -c "https://github.com/linuxdeploy/linuxdeploy/releases/download/continuous/linuxdeploy-x86_64.AppImage"
chmod x linuxdeploy-x86_64.AppImage linuxdeploy-plugin-conda.sh
