joaohf opened a new issue, #4580:
URL: https://github.com/apache/couchdb/issues/4580

   [NOTE]: # ( ^^ Provide a general summary of the request in the title above. ^^ )
   
   ## Summary
   
   Prepare couchdb to support deterministic builds.
   
   ## Desired Behaviour
   
   For same use cases [deterministic build](https://reproducible-builds.org/docs/deterministic-build-systems/) is necessary. Erlang 25 supports that via [compile flags](https://github.com/erlang/otp/pull/5965) like:
   
   ```
   export ERL_COMPILER_OPTIONS="deterministic"
   ```
   
   In fact, when setting ERL_COMPILER_OPTIONS to `deterministic` the couchdb build as expected. However a few things should be fixed:
   
   ```
   WARNING: couchdb-3.3.2-r0 do_package_qa: QA Issue: File /opt/couchdb/lib/couch-3.3.2/priv/couch_js/86/util.d in package couchdb contains reference to TMPDIR
   File /opt/couchdb/lib/couch-3.3.2/priv/couch_js/86/main.d in package couchdb contains reference to TMPDIR
   File /opt/couchdb/lib/couch-3.3.2/priv/couch_ejson_compare/couch_ejson_compare.d in package couchdb contains reference to TMPDIR
   File /opt/couchdb/releases/RELEASES in package couchdb contains reference to TMPDIR [buildpaths]
   ```
   
   I'm building couchdb using Yocto Project and there is a quality assurance step which verifies if all installed files do not have references to the build host paths. It looks like the file: _/opt/couchdb/releases/RELEASES_ has some build paths inside the file.
   
   The Makefile says to install the output from rel/couchdb into the destination folder:
   
   ```
   # target: install- install CouchDB :)
   install: release
           @echo
           @echo "Notice: There is no 'make install' command for CouchDB 2.x+."
           @echo
           @echo "    To install CouchDB into your system, copy the rel/couchdb"
           @echo "    to your desired installation location. For example:"
           @echo "    cp -r rel/couchdb /usr/local/lib"
   ```
   
   But installing everything from rel/couchdb also brings some compilation files (.d, .o), I think these files is not necessary to be installed:
   
   ```
   File /opt/couchdb/lib/couch-3.3.2/priv/couch_js/86/main.d in package couchdb contains reference to TMPDIR
   File /opt/couchdb/lib/couch-3.3.2/priv/couch_ejson_compare/couch_ejson_compare.d in package couchdb contains reference to TMPDIR
   ```

   Thanks for reaching out @joaohf and for giving a it a try to build CouchDB with a deterministic option. We could probably even make that a configure option or even the default.
   
   Good find about .d .o files we do not need to installed those should not be included in the release. It's an omission on our part.
