Magic/File problems

Magic/File problems

[Jeff Mitchell]

On my host system I have the "file" utility version 5.05. The version in 
poky/in my build directories is version 5.04. I'm seeing a lot of builds 
fail with the following:

| error: magic_load(ms, /usr/share/misc/magic) failed: File 5.4 supports 
only version 7 magic files. `/usr/share/misc/magic.mgc' is version 8

Note that the version there is 5.4; this doesn't match anything as far 
as I can tell.

Any ideas?

Thanks,
Jeff

Jeff,

Which version of poky are you working with? There was a problem that we 
had with file at one point and thought was fixed. If you check in your
tmp/sysroots directory for the host machine, do you have a file.real?

We needed to create a cover script which correctly pointed file to the 
right magic.mgc file.

Hope that helped.

Sau!

Git master as of that point. Revision 
46cf540e63a848512617b20fd8492f81bfb2f704

I do have a tmp/sysroots/x86_64-linux/usr/bin/file.real -- although I'm 
building for BeagleBoard, and don't have one in that directory.

Thanks,
Jeff

I was experiencing same issue today with latest Yocto master ca394457c5d7b2cb4544de7ce2d29008ec6173ae (in Fedora R15):

| error: magic_load(ms, /usr/share/misc/magic) failed: File 5.4 supports only version 7 magic files. `/usr/share/misc/magic.mgc' is version 8

This seems to be a problem with rpmbuild using the wrong magic file from rpmfcClassify. This kind of simple fix in package_rpm.class appears to work:

Defines _rpmfc_magic_path variable:
