Description Mason Jones 2016-01-12 01:24:25 UTC 
Description of problem:
Attempting to run supermin on Centos 7.2 fails because it cannot determine package manager.

Version-Release number of selected component (if applicable):
supermin 5.1.14 (built from source)
Centos 7.2.1511

How reproducible:
Easily

Steps to Reproduce:
1. Setup Centos 7.2.1511 Vagrant image
2. Download and build supermin 5.1.14
3. Run './src/supermin --list-drivers'

Actual results:
arch/pacman	not-detected
debian/dpkg	not-detected
mageia/rpm	not-detected
opensuse/rpm	not-detected
ibm_powerkvm/rpm	not-detected
fedora/rpm	not-detected

Expected results:
Should detect fedora/rpm, I assume.

Additional info:
None.
Comment 1 Richard W.M. Jones 2016-01-12 09:03:31 UTC 
This usually happens because you don't have all the dependencies
installed.  I think in this case you're likely to be missing
`rpm-devel'.  (The messaging could be a bit better though).

What's the full output from ./configure?

Output from running ./configure

This is the output from running ./configure in the Centos 7.2 Vagrant, after additionally installing rpm-devel.
Comment 3 Mason Jones 2016-01-12 17:33:03 UTC 
Thanks for the response. I tried again after installing rpm-devel, but it didn't change anything, unfortunately. The full yum install command I'm running prior to building supermin is:

yum install -y gcc ocaml ocaml-findlib e2fsprogs-devel glibc-static rpm-devel

I've attached the output from running ./configure. Thanks again for the help.
Comment 4 Mason Jones 2016-01-13 00:28:02 UTC 
Okay, I figured it out, though it took a bit since I'm totally new to ocaml! The problem was that although it detected rpm and rpm2cpio, it wasn't finding yumdownload in the fedora_detect() function in rpm.ml. I hadn't installed yum-utils, which turns out to be needed. I added that to the yum install list, and it's working now. Thanks for the pointer to investigate the dependencies more fully. Probably some additional documentation on those wouldn't hurt.
Comment 5 Richard W.M. Jones 2016-01-14 13:59:44 UTC 
A useful command is:

  # yum-builddep supermin

which will install all the build deps automatically.

This is mentioned in the README file already, but I have improved
the documentation to reference RHEL.

Closing this bug per comment 4 and comment 5.
Comment 6 Mason Jones 2016-01-14 16:41:59 UTC 
Right, I tried using that yum-builddep command, but got a message that it didn't know about supermin or couldn't get the information (I don't recall the exact message now). I'm not a yum expert so I'm not sure if there was something more to do there. In any case, problem solved this time, thanks very much.
