Anybody know where logger(1) went?

logger seems to be part of util-linux-systemd nowadays. But coolo added today to the Factory prjconf FileProvides: /bin/logger util-linux-systemd

So you should be able to require /bin/logger (or util-linux-systemd).

Thanks... but in e.g. 13.1 logger is /usr/bin/logger, not /bin/logger... So then won't this package (and every other package that uses logger(1)) still need a conditional test for factory vs. others? -Archie -- Archie L.

You tell me 13.1 has no /bin/logger ?

My mistake: `which logger` says /usr/bin/logger, but I didn't realize there is also a symlink /bin/logger -> /usr/bin/logger. However, now 13.1 doesn't build with either /bin/logger or /usr/bin/logger as the requirement: Building twilio-utils.spec for openSUSE_13.1/i586 Getting buildinfo from server and store to /home/archie/obs/network:telephony/twilio-utils/.osc/_buildinfo-openSUSE_13.1-i586.xml Getting buildconfig from server and store to /home/archie/obs/network:telephony/twilio-utils/.osc/_buildconfig-openSUSE_13.1-i586 buildinfo is broken... it says: unresolvable: nothing provides /bin/logger Building twilio-utils.spec for openSUSE_13.1/i586 Getting buildinfo from server and store to /home/archie/obs/network:telephony/twilio-utils/.osc/_buildinfo-openSUSE_13.1-i586.xml Getting buildconfig from server and store to /home/archie/obs/network:telephony/twilio-utils/.osc/_buildconfig-openSUSE_13.1-i586 buildinfo is broken... it says: unresolvable: nothing provides /usr/bin/logger So it still appears a conditional test of some kind will be necessary... unless I'm still missing something.

You can add this to your prj's prjconf %if %suse_version < 1320 FileProvides: /bin/logger util-linux %endif

Except (a) I don't think I have the rights to do that (network:telephony and/or factory) and (b) shouldn't this problem be solved in a more global way so that every other program that requires logger(1) will not face the same issue? Apologies if I'm missing something; I have not mucked with prjconf before. Thanks, -Archie -- Archie L.

Yeah, the package probably should just BuildReqiure: util-linux.

Which takes us neatly right back to where this whole thread started :) In summary... it appears the best I can do is this conditional, package-specific solution, unless someone has a more elegant one. %if %suse_version < 1320 Requires: util-linux %else Requires: util-linux-systemd %endif Thanks, -Archie -- Archie L.

From your build log:

I'm far from being an expert on this, and I don't know twilio-utils, but why would a package need a logger at *build time*?

This is a very common portability trick: locate a utility via AC_PATH_PROG() at build time, instead of making non-portable assumptions about its location that will only fail at runtime. logger(1) is a perfect example - e.g. it could be in /bin/logger or /usr/bin/logger, and in openSUSE it's in fact in both locations (with a symlink), but on other Linux systems... who knows?? Hence the use of AC_PATH_PROG() to find it at build time. -Archie -- Archie L.

Well, if your configure can find it in $PATH, your exec is most likely to do the same.

Yeah - that's the whole point :) In any case, it is the reverse situation which is more critical. If you DON'T check for it at build time, then if it's NOT there you'll only discover the error at runtime. With the ./configure test, you discover the problem at build time instead. This is the whole point of using ./configure - figure out where stuff is at build time (or figure out that stuff can't be found and report an error), so that the following assertion is true: IF the thing builds successfully, THEN it will work properly at runtime - no matter what O/S you build it on. -Archie -- Archie L.

The problem with this: if your program hard codes the path in the binary, your spec file doesn't need to require util-linux but the exact path hardcoded.

Fine - except I already tried that and it didn't work and there's no way for me to fix it!
