Dear Martin Perina, We found some issues with the oVirt Engine master branch when updating the version via git pull. We then performed the make command: make clean install-dev PREFIX=~/ovirt_engine_master DEV_BUILD_SCL_POSTGRESQL=1 It seems a new dependency was added for isort, so the make fails with the following error: -------------------------------------------------------------------------------------------------------------------- packaging/setup/plugins/ovirt-engine-rename/ovirt-engine/database.py:313:21: E126 continuation line over-indented for hanging indent packaging/setup/plugins/ovirt-engine-rename/ovirt-engine/database.py:314:21: E126 continuation line over-indented for hanging indent packaging/setup/plugins/ovirt-engine-common/base/core/duplicated_constants_check.py:109:17: E124 closing bracket does not match visual indentation + ret=1 + which isort + echo 'WARNING: tool '\''isort'\'' is missing' WARNING: tool 'isort' is missing + exit 1 make[1]: *** [validations] Error 1 make[1]: Leaving directory `/home/srosenbe/Documents/git/ovirt-engine' make: *** [all-dev] Error 2 -------------------------------------------------------------------------------------------------------------------- To attempt to address this issue, we guessed and installed python2-isort through yum, though the readme states it is optional. Though the process continued, it then failed in the python module: /home/srosenbe/Documents/git/ovirt-engine/packaging/pythonlib/ovirt_engine/service.py That error is here: --------------------------------------------------------------------------------------------------------------------------- --- /home/srosenbe/Documents/git/ovirt-engine/packaging/pythonlib/ovirt_engine/service.py:before 2018-02-12 12:17:26 +++ /home/srosenbe/Documents/git/ovirt-engine/packaging/pythonlib/ovirt_engine/service.py:after 2018-02-26 12:07:11.233915 @@ -31,6 +31,7 @@ import time import daemon + from dateutil import tz + exit 1 make[1]: *** [validations] Error 1 make[1]: Leaving directory `/home/srosenbe/Documents/git/ovirt-engine' make: *** [all-dev] Error 2 --------------------------------------------------------------------------------------------------------------------------- Please advise if you have a quick fix or when this issue will be addressed. Thank you for your time and consideration. With Best Regards. Steven Rosenberg.
