re librdmacm-devel dependency on librdmacm

[Or Gerlitz]

Hi Sean,

I just realized the librdmacm-devel (version 1.0.8-5.el5 is installed on 
the system I hit that) is dependent on librdmacm, and wasn't sure if its 
a bug or a feature... the dependency is created through 
/usr/lib64/librdmacm.so which is soft link to the obj file installed by 
librdmacm.

Or.

This is Red Hat's package, not mine, so I think they would need to answer this.  I guess I don't understand the problem, but why wouldn't the developer package depend on the real library?  Does libibverbs have a similar devel package?

Every devel package I have ever used has depended on the underlying library. 
A-lot of times the developer packages might include the header files, etc.

I don't work for Red Hat but I don't think there's any issue here.

In a 2nd thought, this dependancy isn't so terrible, and maybe even
the usual track for such packages, thx anyway.

This is a normal policy for RPM based distributions.  I believe deb
based distributions do something different, but don't recall the details.

DEB is the same. The linker requires the actual .so to be able to
link, so a -devel package without a corrisponding (MATCHING) lib
package is useless.
