Dependencies ============ .. index:: Dependencies -XXX: List dependencies +RTEMS applications are developed using cross-development tools running on a +host computer, typically your desktop or a special build server. All RTEMS +tools and runtime libraries are built from source on your host machine. The +RTEMS Project does not maintain binary builds of the tools. This may appear be +the opposite to what you normally experience with host operating systems, and +it is, however this approach works well. RTEMS is not a host operating system +and it is not a distrbution. Providing binary packages for every possible host +operating system is to big a task for the RTEMS Project and it is not a good +use of the core developers time. Their time is better spent making RTEMS better +and faster. +Developer Computer +------------------ + +The rule for selecting a computer for a developer is `more is better` but we do +understand there are limits. Projects set up different configurations and what +is described here is not an approved set up, rather it is a guide. Some +projects have a suitable development machine per developer while others set up +a tightly controlled central build server. RTEMS is flexible and lets you +engineering a development environment that suites you. The basic specs are: + +- Multicore processor +- 8G bytes RAM +- 256G harddisk + +RTEMS makes no demands on graphics. + +Host Software +------------- + +A wide range of host operating systems and hardware can be used. The host +operating systems supported are: + +- Linux +- FreeBSD +- NetBSD +- Apple OS X +- Windows +- Solaris + +The functionality on POSIX operating such as Linux and FreeBSD is similar and +most features on Windows are supported but you are best to ask on +:r:list:`users` if you have a specific question. + +Install and set up your host operating system. We recommend you maintain your +operating system by installing any updates. |
