4# This build script is for running the QEMU build in a container
5#
6# It expects to be run in with the qemu source present in the directory called
7# '$WORKSPACE/qemu', where WORKSPACE is an environment variable.
8#
9# In Jenkins configure the git SCM 'Additional Behaviours', 'check-out to a sub
10# directory' called 'qemu'.
11#
12# When building locally set WORKSPACE to be the directory above the qemu
13# checkout:
14#   git clone https://github.com/qemu/qemu
15#   WORKSPACE=$PWD/qemu ~/openbmc-build-scripts/qemu-build.sh

19# Script Variables:
20#  http_proxy         The HTTP address of the proxy server to connect to.
21#                     Default: "", proxy is not setup if this is not set
22#  WORKSPACE          Path of the workspace directory where the build will
23#                     occur, and output artifacts will be produced.
