RPM and libmagic

RPM and libmagic

[Saul Wold]

Mark,

I recently found a problem with RPM and libmagic, specificly the rpmdeps 
command as it's used in package.bbclass. The issue being that it was not 
finding the correct magic.mgc file.  I notice that we wrap the other RPM 
commands, but not rpmdeps.

Additionally, as I have discovered the wrappers that we have in place 
currently does not define a MAGIC environment variable to correct the 
location.

I know rpm and friends are an important part of OE packaging, so I 
wanted to check with you first about the correct location to set this, 
if we should use the MAGIC or pass a --define '%_rpmfc_magic_path ...' 
on the command line.

Please advise, I know you are traveling, and I can implement the change 
once we figure out the correct approach.

Thanks

That is likely a bug.

Is the proper variable "MAGIC" or is it's something else?

I believe the intention is to pass the _rpmfs_magic_path..  that patch can be
made up of other potential dynamic results.  If the wrapper is building up
_librpm (something like that), then we can use:

%_rpmfc_magic_path %{_rpmlib}/../../share/magic

Note about is ramblings, not actual code.. ;)
