# CTestCoverageCollectGCOV
|
|
# ------------------------
|
|
#
|
|
# This module provides the function ``ctest_coverage_collect_gcov``.
|
|
# The function will run gcov on the .gcda files in a binary tree and then
|
|
# package all of the .gcov files into a tar file with a data.json that
|
|
# contains the source and build directories for CDash to use in parsing
|
|
# the coverage data. In addtion the Labels.json files for targets that
|
|
# have coverage information are also put in the tar file for CDash to
|
|
# asign the correct labels. This file can be sent to a CDash server for
|
|
# display with the
|
|
# :command:`ctest_submit(CDASH_UPLOAD)` command.
|
|
#
|
|
# .. command:: cdash_coverage_collect_gcov
|
|
#
|
|
# ::
|
|
#
|
|
# ctest_coverage_collect_gcov(TARBALL <tarfile>
|
|
# [SOURCE <source_dir>][BUILD <build_dir>]
|
|
# [GCOV_COMMAND <gcov_command>]
|
|
# [GCOV_OPTIONS <options>...]
|
|
# )
|
|
#
|
|
# Run gcov and package a tar file for CDash. The options are:
|
|
#
|
|
# ``TARBALL <tarfile>``
|
|
# Specify the location of the ``.tar`` file to be created for later
|
|
# upload to CDash. Relative paths will be interpreted with respect
|
|
# to the top-level build directory.
|
|
#
|
|
# ``SOURCE <source_dir>``
|
|
# Specify the top-level source directory for the build.
|
|
# Default is the value of :variable:`CTEST_SOURCE_DIRECTORY`.
|
|
#
|
|
# ``BUILD <build_dir>``
|
|
# Specify the top-level build directory for the build.
|
|
# Default is the value of :variable:`CTEST_BINARY_DIRECTORY`.
|
|
#
|
|
# ``GCOV_COMMAND <gcov_command>``
|
|
# Specify the full path to the ``gcov`` command on the machine.
|
|
# Default is the value of :variable:`CTEST_COVERAGE_COMMAND`.
|
|
#
|
|
# ``GCOV_OPTIONS <options>...``
|
|
# Specify options to be passed to gcov. The ``gcov`` command
|
|
# is run as ``gcov <options>... -o <gcov-dir> <file>.gcda``.
|
|
# If not specified, the default option is just ``-b``.
|
|
#
|
|
# ``QUIET``
|
|
# Suppress non-error messages that otherwise would have been
|
|
# printed out by this function.
