Environment Variables

Env Var	Purpose
FASTBUILD_TEMP_PATH	Override system temp path for FASTBuild to use.
FASTBUILD_BROKERAGE_PATH	Set location of the Brokerage Path for distributed compilation.
FASTBUILD_WORKERS	Set the list of workers explicitly.
FASTBUILD_CACHE_PATH	Set the location of the cache.
FASTBUILD_CACHE_PATH_MOUNT_POINT	Set the path to be verified as a mount point. (OSX & Linux)
FASTBUILD_CACHE_MODE	Set the cache mode.

FASTBuild uses the system temp dir. This can be overridden by setting the FASTBUILD_TEMP_PATH. This can be useful in certain cases, such as when certain Anti-Virus software is used that prevents executables being spawned from the temp directory.

FBuildWorkers signal their availability by writing a token to the "Brokerage Path". The location of the brokerage path can be set via the FASTBUILD_BROKERAGE_PATH.

The list of FBuildWorkers can be set explicitly as a ; delimited list via the FASTBUILD_WORKERS environment variable.

The location of the FASTBuild cache can be set via the FASTBUILD_CACHE_PATH environment variable instead of via the .CachePath option in the Settings function.

The location of the FASTBuild cache mount point for OSX and Linux can be set via the FASTBUILD_CACHE_PATH_MOUNT_POINT environment variable instead of via the .CachePathMountPoint option in the Settings function.

The cache mode can be set via the FASTBUILD_CACHE_MODE environment variable, instead of via the command line -cache options.
