On Windows, macOS, and Linux, it is best to install Anaconda for the local user, which does not require administrator permissions and is the most robust type of installation. However, if you need to, you can install Anaconda system wide, which does require administrator permissions.
You can use silent mode to automatically accept default settings and have no screen prompts appear during installation. We recommend upgrading your operating system. Most OS that are no longer supported in the latest Anaconda are no longer getting security updates.
Upgrading your OS allows you to get the latest packages, performance improvements, bug fixes, etc. To use Anaconda on older operating systems, download from our archive. You will not be able to use conda to update or install packages beyond the Anaconda version noted in the table below, unless you limit it to versions available at the time that particular version of Anaconda was released.
Any compilation that uses a sysroot other than the system sysroot is said to be "cross-compiling. Unfortunately, some software tools do not handle sysroots in intuitive ways. CMake is especially bad for this. Even though the compiler itself understands its own sysroot, CMake insists on ignoring that.
We've filed issues at:. In order to teach CMake about the sysroot, you must do additional work. In particular, you'll need to copy the cross-linux. The compiler packages listed above are small packages that only include the activation scripts and list most of the software they provide as runtime dependencies.
This design is intended to make it easy for you to customize your own compiler packages by copying these recipes and changing the flags. We have been careful to select good, general purpose, secure, and fast flags. We have also used them for all packages in Anaconda Distribution 5. When changing these flags, remember that choosing the wrong flags can reduce security, reduce performance, and cause incompatibilities.
The Clang package recipe is in the clang folder. The main material is in the llvm-compilers-feedstock folder. The name here does not matter but the output names below do. Before any packaging is done, run the build. In this recipe, values are changed here.
Those values are inserted into the activate scripts that are installed later. With those changes to the activate scripts in place, it's time to move on to installing things. Look back at the clang folder's meta. Here's where we change the package name. The script reference here is another place you might add customization. You'll either change the contents of those install scripts or change the scripts that those install scripts are installing.
Note that we make the package clang in the main material agree in version with our output version. This is implicitly the same as the top-level recipe. The clang package sets no environment variables at all, so it may be difficult to use directly.
The Anaconda configuration files are written in the INI format that can be processed by configparser. The files consist of sections, options and comments. Each section is defined by a [section] header. Each comment has to start on a new line prefixed by the character. The default configuration file provides a full default configuration of the installer.
It defines and documents all supported sections and options. The profile configuration files allow to override some of the configuration options for specific profiles and products. Anaconda previously used so called install classes for the product-specific configuration.
Install classes were completely removed and replaced by the profile configuration files. These configuration files used to be called product configuration files for some time.
Each profile has a unique profile id. It is a lower-case string with no spaces that identifies the profile. The id can be arbitrary, but the convention is to use the name of the configuration file for example, fedora-server.
The profile can be specified by the inst. Otherwise, the profile will be chosen based on the os-release values of the installation environment. The installer will use a profile with the best match.
The [Profile] section defines a profile id of the profile. Optionally, it can specify a profile id of a base profile. For example, fedora is a base profile of fedora-server. We support a simple inheritance of profile configurations. The installer loads configuration files of the base profiles before it loads the configuration file of the specified profile.
For example, it will first load the configuration for fedora and then the configuration for fedora-server. We are not going to support multiple inheritance. It would significantly increase the complexity of the profile configuration files in an unintuitive way. You can easily compare two configuration files and verify the parts they are supposed to share.
We do that in our unit tests. The [Profile Detection] defines the operating system id and the variant id that should match os-release values of the expected installation environment.
