+# Casaconda
+Experimental project to test BrainVISA compilation using a build environment setup using Conda.
+
+## Setup of a build environment using Conda
+
+### From scratch
+
+Install OpenGL dev packages
+```
+sudo apt install libglu1-mesa-dev
+```
+
+Select a directory
+```
+casaconda=/somewhere
+```
+
+Download project with config (and source list)
+```
+git clone https://github.com/sapetnioc/casaconda "$casaconda"
+```
+
+Download sources and setup conda directory
+```
+"$casaconda/setup_dev"
+```
+
+Build everything
+```
+"$casaconda/bv_env" bv_maker
+```
+
+At the time of this writing, documentation building is failing.
+
+### Build a repository for Anatomist
+
+It is necessary to have a complete build environment since the packaging scripts only do packages with `make install...` commands.
+
+Install Conda build
+```
+"$casaconda/conda/bin/mamba" install -y conda-build
+```
+
+Run the package creation recipe
+```
+"$casaconda/conda/bin/mamba" build ~/casaconda/recipe
+```
+
+Publish the resulting repository
+```
+rsync -a --delete "$casaconda/conda/conda-bld/" brainvisa@brainvisa.info:/var/www/html/brainvisa.info_download/conda/
+```
+
+### Install Anatomist from a repository
+
+One can use the repository located in `https://brainvisa.info/download/conda` but it can be replaced by a local directory too, for instance: `file:///home/me/casaconda/conda/conda-bld`.
+
+Install OpenGL libraries (tested on Ubuntu/Windows-WSL2)
+```
+sudo apt install libgl1-mesa-glx libopengl
+```
+
+Select an install directory:
+```
+conda=/tmp/conda
+```
+
+Install Conda. I recommend installing a version that incorporates Mamba (a really much faster C++ implementation for resolving package dependencies) and that defaults to conda-forge (a very well-maintained community package repository with no legal constraints on use).
+```
+cd /tmp
+wget https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-Linux-x86_64.sh
+sh Mambaforge-Linux-x86_64.sh -ubp "$conda"
+rm Mambaforge-Linux-x86_64.sh
+```
+
+Install Anatomist. It is possible to substitute the repository located in `https://brainvisa.info/download/conda` by a local directory, for instance: `file:///home/me/casaconda/conda/conda-bld`.
+
+```
+"$conda/bin/mamba" install -c https://brainvisa.info/download/conda -y anatomist
+```
+
+
+Activate the conda repository and use Anatomist, Aims or whatever:
+```
+. "$conda/bin/activate"
+anatomist
+```

+  description: |
+    BrainVISA provides a complete, modular, infrastructure for neuroimaging
+    software. It helps organizing heterogeneous software and data and
+    provides a common general graphical interface for users.
+    BrainVISA is thus a set of tools rather than a single software.
