Hello cephers, I am new this ceph development although have been using it for long time. At first I started building and followed the same steps described the the github. ./do_cmake.sh cd build make I changed some code in ceph-detect init and added proper test cases as well but the test cased failed. Could you please suggest me what is going wrong here? sudo ctest --output-on-failure -R run-tox-ceph-detect-init Test project /home/muislam/ceph_upstream/ceph/build Start 15: run-tox-ceph-detect-init 1/1 Test #15: run-tox-ceph-detect-init .........***Failed 0.25 sec /home/muislam/ceph_upstream/ceph/src/ceph-detect-init/run-tox.sh: line 30: /tmp/ceph-detect-init-virtualenv/bin/activate: No such file or directory Traceback (most recent call last): File "/bin/tox", line 9, in <module> load_entry_point('tox==1.4.2', 'console_scripts', 'tox')() File "/usr/lib/python2.7/site-packages/tox/_cmdline.py", line 24, in main config = parseconfig(args, 'tox') File "/usr/lib/python2.7/site-packages/tox/_config.py", line 23, in parseconfig parseini(config) File "/usr/lib/python2.7/site-packages/tox/_config.py", line 170, in __init__ config) File "/usr/lib/python2.7/site-packages/tox/_config.py", line 223, in _makeenvconfig for depline in reader.getlist(section, "deps"): File "/usr/lib/python2.7/site-packages/tox/_config.py", line 296, in getlist s = self.getdefault(section, name, None) File "/usr/lib/python2.7/site-packages/tox/_config.py", line 389, in getdefault x = self._replace(x) File "/usr/lib/python2.7/site-packages/tox/_config.py", line 489, in _replace return rexpattern.sub(self._sub, x) File "/usr/lib/python2.7/site-packages/tox/_config.py", line 402, in _sub (key, envkey)) tox.ConfigError: ConfigError: substitution 'env:NO_INDEX:': 'NO_INDEX:' not found in environment 0% tests passed, 1 tests failed out of 1 Total Test time (real) = 0.31 sec The following tests FAILED: 15 - run-tox-ceph-detect-init (Failed) Errors while running CTest Thanks in advance.
