Hi! I am trying to build a newer swig version for el7 starting from the srpm for f27 .. locally on a el7 machine i built the rpm (with java removal from original spec) and the resulting srpm i tried to build on copr .. but i have some errors that seems not related to package : https://copr-be.cloud.fedoraproject.org/results/asevcenc/science-utils/sr... stdout: Downloading swig-3.0.12.tar.gz stderr: Could not execute srpm: 'ns2' Traceback (most recent call last): File "/usr/bin/copr-rpmbuild", line 96, in main action(args, config) File "/usr/bin/copr-rpmbuild", line 126, in build_srpm provider.produce_srpm() File "/usr/lib/python3.6/site-packages/copr_rpmbuild/providers/scm.py", line 115, in produce_srpm return run_cmd(cmd, cwd=self.repo_subpath) File "/usr/lib/python3.6/site-packages/copr_rpmbuild/helpers.py", line 66, in run_cmd raise RuntimeError(result.stderr) RuntimeError: Could not execute srpm: 'ns2' given that i am really new to copr usage i might miss some procedures .. does anyone have any idea about the error and/or workflow with copr? so far my experience is just using copr-cli to upload a srpm.. Thank you! Adrian
