I am changing the Summary as supposing EAPI=5 sets BDEPEND would not have any effect as that EAPI does not even recognise BDEPEND.
Thanks, Jeroen. scons-util.eclass tackles this 10 lines down: if [[ ${EAPI:-0} == [0123456] ]]; then DEPEND=${BDEPEND} unset BDEPEND fi
I guess I am late to the party. I have attached what I did.
Created attachment 617348 [details, diff] sci-geosciences/gpsd: Update v9999 to EAPI 7
Created attachment 617350 [details, diff] sci-geosciences/gpsd: Update v3.19 to EAPI 7
Created attachment 633108 [details, diff] Updated ebuilds for 3.19, 3.20 and 9999 Thanks Edward! Here's my latest attempt based on your changes and stuff I ran into myself recently. It adds 3.20, a more robust workaround for deleting the scons-installed python stuff, switch to the dialout group and acct-user scheme and workaround for recent changes to the build system. BTW: According to my tests, the CC and CXX variables are still required to pass the actual compiler in use (e.g. clang or cross-compiler) to scons.
Created attachment 633560 [details, diff] Updated ebuilds for 3.19, 3.20 and 9999 Latest attempt, fixing the switch to the dialout group by actually supplying the group to the build system. Also, apparently, the 3.20 ebuild was missing from the previous patch.
Created attachment 633564 [details, diff] Make systemd integration work Parking this here since it depends on the previous patch until we have decided whether and how to split these patches into separate bugs.
Nearly all of this has been addressed in one way or another in gpsd-3.20 and the updated gpsd-9999. Thanks a bunch to the folks submitting information on this bug. To avoid confusion, if I missed anything critical, please open a new bug. Thanks!
thanks for this new ebuild. one remaining issue reported in bug #734352
another issue is BDEP missing scons filed in bug #734364
