Hi All, Are Pharo linux minheadless builds itimer or threaded heartbeat? (all the listings below are extracts, not the complete file / page) The file list on bintray suggests that they are itimer: https://bintray.com/opensmalltalk/vm/cog/201907112020#files pharo.cog.spur+sdl2-cmake-minhdls_linux64x64_itimer_201907112020.tar.gz 6 days ago 4.23 MB pharo.cog.spur-cmake-minhdls_linux64x64_itimer_201907112020.tar.gz 6 days ago 4.22 MB While travis indicates that only threaded heartbeat versions are built: https://travis-ci.org/OpenSmalltalk/opensmalltalk-vm/builds/553922116 Setting environment variables from .travis.yml $ export ARCH="linux64x64" $ export FLAVOR="pharo.cog.spur" $ export CPU_ARCH="x64" $ export HEARTBEAT="threaded" $ export BUILD_WITH_CMAKE="yes" .travis.yml agrees with the travis output: - stage: "Minheadless CMake builds" - env: ARCH="linux32x86" FLAVOR="pharo.cog.spur" CPU_ARCH="x86" HEARTBEAT="threaded" BUILD_WITH_CMAKE="yes" - env: ARCH="linux64x64" FLAVOR="pharo.cog.spur" CPU_ARCH="x64" HEARTBEAT="threaded" BUILD_WITH_CMAKE="yes" And pack-vm.sh seems to be doing the right thing when determining how to name the archive: for dir in */; do if [[ "${ARCH}" == *"ARM"* || "${dir}" == *"ht/" ]]; then name="${IDENTIFIER}" else name="${IDENTIFIER_ITIMER}" fi Unfortunately figuring out which VM is being used isn't helped by the fact that "pharo --version" doesn't work with minheadless: $ ./pharo --version Opening Image: --version Opening Image: No such file or directory Error opening image file: --version Thanks, Alistair
