# shell script for running the boost regression test suite and generating
# a html table of results.

# Set the following variables to configure the operation. Variables you
# should set, i.e. usually required are listed first. Optional variables
# have reasonable defaults for most situations.


### THESE SHOULD BE CHANGED!

#
# "boost_root" points to the root of you boost installation:
# This can be either a non-exitent directory or an already complete Boost
# source tree.
#
boost_root="$HOME/CVSROOTs/Boost/boost_regression"

#
# Wether to fetch the most current Boost code from CVS (yes/no):
# There are two contexts to use this script in: on an active Boost CVS
# tree, and on a fresh Boost CVS tree. If "yes" is specified here an attempt
# to fetch the latest CVS Boost files is made. For an active Boost CVS
# the CVS connection information is used. If an empty tree is detected
# the code is fetched with the anonymous read only information.
#
cvs_update=no

#
# "test_tools" are the Boost.Build toolsets to use for building and running the
# regression tests. Specify a space separated list, of the Boost.Build toolsets.
# Each will be built and tested in sequence.
#
test_tools=gcc

#
# "toolset" is the Boost.Build toolset to use for building the helper programs.
# This is usually different than the toolsets one is testing. And this is
# normally a toolset that corresponds to the compiler built into your platform.
#
toolset=gcc

#
# "comment_path" is the path to an html-file describing the test environment.
# The content of this file will be embedded in the status pages being produced.
#
comment_path="$boost_root/../regression_comment.html"
#
# "test_dir" is the relative path to the directory to run the tests in,
# defaults to "status" and runs all the tests, but could be a sub-directory
# for example "libs/regex/test" to run the regex tests alone.
#
test_dir="status"


### DEFAULTS ARE OK FOR THESE.

#
# "exe_suffix" the suffix used by exectable files:
# In case your platform requires use of a special suffix for executables specify
# it here, including the "." if needed. This should not be needed even in Windows
# like platforms as they will execute without the suffix anyway.
#
exe_suffix=

#
# "bjam" points to your built bjam executable:
# The location of the binary for running bjam. The default should work
# under most circumstances.
#
bjam="$boost_root/tools/jam/src/bin/bjam$exe_suffix"

#
# "process_jam_log", and "compiler_status" paths to built helper programs:
# The location of the executables of the regression help programs. These
# are built locally so the default should work in most situations.
#
process_jam_log="$boost_root/dist/bin/process_jam_log$exe_suffix"
compiler_status="$boost_root/dist/bin/compiler_status$exe_suffix"

#
# "boost_build_path" can point to additional locations to find toolset files.
#
boost_build_path="$HOME/.boost-build"
