@ -3,15 +3,17 @@ Developing ARTIQ
We describe two different approaches to creating a development environment for ARTIQ.
The first method uses existing pre-compiled Anaconda packages for the development environment.
This is fast and convenient because it avoids compiling the entire toolchain but developing individual components within the toolchain requires extra care.
The first method uses existing pre-compiled Anaconda packages and the ``artiq-dev`` meta-package for the development environment.
This is fast and convenient because it avoids compiling the entire toolchain.
Consequently, some ARTIQ developers as well as the buildbot that's used for continuous integration all employ this method to build the ``artiq`` Anaconda packages and the bitstreams.
It is completely sufficient to develop and tweak the ARTIQ code and to build
bitstreams.
Some ARTIQ developers as well as the buildbot employs this method for continuous integration to build the ``artiq`` Anaconda packages and the bitstreams.
The second method builds most components in the toolchain from their sources.
This takes time and and care to reproduce precisely but it gives absolute control over the components and an immediate handle at developing them.
Some ARTIQ developers use this method.
But with the meta-pakage developing individual components within the toolchain requires extra care.
Consequently, the second method builds most components in the toolchain from their sources.
This takes time and care to reproduce accurately but it gives absolute control over the components and an immediate handle at developing them.
Some ARTIQ developers use this second method of building the entire toolchain
from sources.
It is only recommended for developers and advanced users.
