IMHO these things are orthogonal. If BR2_PACKAGE_LINUX_PAM is selected, it will be built before busybox - what's the difference? If BR2_PACKAGE_LINUX_PAM is not selected, busybox.mk extra dependencies are not in effect - correct? If CONFIG_PAM is not selected in busybox, it is not affected by PAM other than the fact that PAM will be built earlier. The only situation when bad outcome is possible: CONFIG_PAM is selected in busybox, and BR2_PACKAGE_LINUX_PAM is not selected. But this will be obvious to the user, why busybox does not build. I don't really want to force PAM support in busybox as a consequence of user selection of BR2_PACKAGE_LINUX_PAM alone. The reverse makes more sense: I may add a sub-item in busybox config which enables PAM in both buildroot an busybox. Please let me know if this is acceptable. > > No, see > http://buildroot.org/downloads/manual/manual.html#_gettext_integration_and_interaction_with_packages. > I probably missed this, will fix. For the rest of your comment (fixing config.h post-configure) I need a closer look and some more time.

Well, the thing is that this generally not really how we handle things in Buildroot. In general, as soon as some library is available and provide a feature that can be used by a package, then we automatically use it. Some examples: (1) Having RPC or IPv6 support in the toolchain will automatically enable certain Busybox applet or options. (2) Many packages use a library if available, without having a specific option for it. See for example how bind, ctorrent or libecore use openssl when available. We could have thought of doing the opposite: if CONFIG_PAM is enabled in the Busybox configuration, then we add linux-pam to the dependencies. But unfortunately, this is not possible: we cannot add things to <foo>_DEPENDENCIES depending on the Busybox configuration :-( So, I'd say I would prefer to follow what we do for all other packages. Basically, my understanding of our rule is that we do something that makes sense by default, and if someone really wants linux-pam for something else, but not for Busybox, that someone can do a very simple modification to busybox.mk to change this. Just like if someone wants openssl for something in its system, but not for bind or ctorrent, (s)he would have to make changes in the bind.mk or ctorrent.mk files. > > No, see > > http://buildroot.org/downloads/manual/manual.html#_gettext_integration_and_interaction_with_packages. > > I probably missed this, will fix. > > For the rest of your comment (fixing config.h post-configure) I need > a closer look and some more time.
