Audit dependency chain

[NattyNarwhal]

Testing on a fresh i 7.2 LPAR. Yum bootstrap will install these RPMs by default, so it's a matter of what needs to be installed afterwards. Install rpm-build, rpmdevtools, and curl (to fetch the tarballs). Some things I noticed, using giflib as an example:

• IBM's libtool doesn't declare grep-gnu as a dependency when libtoolize needs it.

Using giflib as an example:

• tar-gnu and bzip2 are not declared. Should this be a dependency on the part of rpm-build? Otherwise, it won't extract the tarball. I assume substitute bzip2 for gzip or xz as needed.

• Some things are declared. Yum will happily install those. It does bring in an undeclared make-gnu dependency.

Transaction Summary
================================================================================
Install       7 Packages

• Rerun, the step for autoreconf (we need to occasionally regenerate the configure scripts, otherwise they won't pick up dynamic linking with PASE svr4 sonames) can't find m4-gnu and libtoolize warns about the missing grep-gnu.

• No cc. Time to add gcc-aix, which only covers C for now.

• diff barfs at the end of packaging. Time for diffutils.

• Successful build.

I think a lot of these are the implied steps of building RPMs. Some are of the RPM's (like GCC, even if autowhatever is depended on explicitly) and undeclared dependencies of say, autotools, but some are implied steps when building the RPM you shouldn't have to worry about. Some of those I can think of:

• For rpm-build

  • Compression tools as needed and maybe tar-gnu (as it is explicitly used) for extracting.

  • make-gnu as it runs the GNU make tool explicitly when building.

  • diffutils for finalizing the package

• For autotools

  • grep-gnu for libtool

  • m4-gnu for what provides autoconf

Building libart_lgpl, triggers something that makes it need coreutils-gnu for mktemp when assembling the RPM. Hmmm.

[NattyNarwhal]

Building lzo exposing no gzip or patch-gnu.

Missing pkg-config.

Also keep in mind this is BuildDepends, not regular Depends. I haven't tested runtime dependencies, and I can do that after my binge with a new LPAR without many assumptions made.
