# This script executes the matrix loops, exclude tests and cleaning.
# The matrix can be configured with the following environment variables: MATRIX_CC,
# MATRIX_CMAKE and MATRIX_REMOTE.
: "${MATRIX_CC:=gcc clang}"
: "${MATRIX_CMAKE:=no yes}"
: "${MATRIX_REMOTE:=no yes}"
# Set this variable to "yes" before calling this script to disregard all
# warnings in a particular environment (CI or a local working copy).  Set it
# to "yes" in this script or in build.sh when a matrix subset is known to be
# not warning-free because of the OS, the compiler or whatever other factor
# that the scripts can detect both in and out of CI.
: "${LIBPCAP_TAINTED:=no}"
# Some OSes have native make without parallel jobs support and sometimes have
# GNU Make available as "gmake".
: "${MAKE_BIN:=make}"
# It calls the build.sh script which runs one build with setup environment
# variables: CC, CMAKE and REMOTE.
