> Please remember, that not every package out there does use an autotools based build system, we also have custom configure scripts, custom makefiles, things like cmake, qmake or even completly different things like ant based build systems for java. All those build systems wont benefit neither from --disable-dependency-tracking nor from --disable-silent-rules. Also, as already pointed out, a package, which currently exists may be unmaintained and useless in the future, so if i dont do the work now and remove the then unneeded package later, i did not spend any additional time for this change. Your requirement would either mean wasted time or another open bug until the package gets removed. Beside that, i did ask you about the case, where "the ebuild does the same and the result is the same". And you did not answer my question, why an EAPI-bump in such cases should be done. And finally, as already pointed out by Rich, you should not talk about any specific EAPI you like/prefer/want to be used everyhwere, but instead about the issue you want to solve. So just point out the issue and ask the maintainer to fix it. If he uses a newer EAPI, good. If he uses another solution, which also fixes the issue, also good. We should not discuss about a specific way to solve some issues, since this is the maintainers choice. Our goal should instead be to fix as many issues as possible with our limited amount of time we have for Gentoo. -- Thomas Sachau Gentoo Linux Developer
