emerge --info for "emerge-armv6z-hardfloat-linux-gnueabi"

I'm trying to crosscompile armv6z basic rootfs.

USE="-*" emerge-armv6z-hardfloat-linux-gnueabi pam failes with: "pam_conv_l.c:(.text+0xb20): undefined reference to `yywrap'".

It's fixed if flex is builded before pam.

pam's version: 1.1.5 and 1.1.3.

No, it's there all right. Maybe it's virtual/yacc that's needed? - Please attach the entire failing build log to this bug report.

build log

Again, it's important that it's cross-building for another arch.

Fix is simple - flex should be RDEPEND, not DEPEND.

It is bug in portage 2.2.0 (bug was at least in alpha90, can reproduce in alpha1-02 and 9999 too). Portage 2.1 works as expected.

[Comment 5 Zac Medico 2012-05-09 18:47:57 UTC]

Portage 2.2 and 2.1 have the same code. The only difference is that Portage 2.2 has some experimental features enabled, such as package sets and preserve-libs. There's no difference in handling of DEPEND and RDEPEND.

Downgrade to portage 2.1.10.57 solved this issue. Upgrade to portage-9999 or 2.2alpha* introduced again.

What's the difference? Are the packages merged in a different order, or what?

With 2.2 pam doesn't merged at all.

Minimal test-case:
mkdir -p /tmp/portage-test
USE="-*" ROOT="/tmp/portage-test" emerge -pv pam

flex should be there, but it isn't

If you move flex to RDEPEND and do that again, flex will be in deps.

This is the expected behavior, regardless of the portage version.

DEPEND - dependencies that are needed for software to compile, RDEPEND - to run, or I'm not right?

Yes, but the --root-deps or --root-deps=rdeps options change dependency resolution behavior. Are you using either of those?

[Comment 13 Vladimir Smirnov (RETIRED) 2012-05-09 19:16:59 UTC]

Created attachment 311281 [details]
emerge --debug -p pam

I've attached debug.log for last case.

[Comment 14 Vladimir Smirnov (RETIRED) 2012-05-09 19:24:15 UTC]

It's still a bug in ebuild: flex is needed on runtime too, so it should be both in RDEPENDs and DEPENDs.

The flex library is static though, right? That might mean that it's only needed at build time.

Anyway, this issue seems similar in some ways to bug 412909.

*** Bug 412909 has been marked as a duplicate of this bug. ***

[Comment 17 James Le Cuirot 2015-05-09 18:07:29 UTC]

This is what HDEPEND was for but it was rejected. Proposing a better alternative is on my rather long todo list.

[Comment 18 Sam James 2022-12-10 01:12:03 UTC]

I think this is fixed with BDEPEND?
