Jan 14 12:33:49 <pespin> Hi, I have been debugging for a while why configure's "AC_CHECK_HEADERS(netinet/sctp.h,,AC_MSG_ERROR(netinet/sctp.h not found))" fails building my recipe (I have lksctp-tools in my DEPENDS and I can see netinet/sctp.h fine under recipe-sysroot).
Jan 14 12:34:28 <pespin> I found it seems OE is providing export CONFIG_SITE with several files, one of them: meta/site/arm-common
Jan 14 12:34:36 <pespin> which contains ac_cv_header_netinet_sctp_h=${ac_cv_header_netinet_sctp_h=no}
Jan 14 12:35:14 <pespin> so my question now is, what's the expected way to specifiy in the .bb recipe that I want to drop the cache and actually do the check?
Jan 14 12:44:15 <rburton> pespin: delete it from the site file, its obviously incorrect (and a header check is trivial, so there's no advantage to having it in site)
Jan 14 12:44:33 <pespin> rburton, so shall I submit a patch against oe-core?
Jan 14 12:44:39 <rburton> eah
Jan 14 12:44:40 <rburton> yeah
Jan 14 12:45:28 <pespin> ok thanks. BTW, I confirm I got it to work by using something like: CACHED_CONFIGUREVARS += "${@bb.utils.contains('PACKAGECONFIG', 'libsctp', 'ac_cv_header_netinet_sctp_h=yes', '',d)}"
Jan 14 16:01:44 <mort> so, what's the deal with the variables named "SOMETHING_${PN}"? Why do some variables just have a normal name, while others are suffixed with _${PN}?
Jan 14 16:02:53 <LetoThe2nd> mort: _${PN} means: only relevant for the specific package. without means, relevant for the whole scope.
Jan 14 16:03:03 <LetoThe2nd> (thats a bit simplified, but catches the essence)
Jan 14 16:04:07 <mort> LetoThe2nd: what does "the whole scope" mean? And why, for example, is DEPENDS relevant for the whole scope while RDEPENDS isn't?
Jan 14 16:05:39 <LetoThe2nd> mort: DEPENDS vs. RDEPENDS is the prime use case. there it means: DEPENDS is relevant for building the whole recipe. RDEPENDS_${PN} on the other hand add the r-dependency only to the main package, and not to any other produced by the recipe. (like -dbg, -dev, ....)
Jan 14 16:51:30 <rburton> mort: RDEPENDS -> runtime depends, so is explicitly per-package
Jan 14 18:30:18 <Crofton|road> Can you linkedin cool kids share this page for us?
