Description Dave Love 2016-01-21 11:42:51 UTC

Description of problem:

The soname of libpapi is libpapi.so (without a version number).  That's obviously wrong, but it specifically breaks anything using it if you have another version of papi installed (in my case as an SCL), e.g. for Lustre support (#1262015).

$ readelf -d /usr/lib64/libpapi.so* | grep SONAME
 0x000000000000000e (SONAME)             Library soname: [libpapi.so]
 0x000000000000000e (SONAME)             Library soname: [libpapi.so]
 0x000000000000000e (SONAME)             Library soname: [libpapi.so]

Version-Release number of selected component (if applicable):

papi-5.1.1-11.el6.x86_64

Comment 2 William Cohen 2016-01-21 14:14:12 UTC

The lack of so version for the older papi library is not ideal. Changing it to be versioned may break existing code customer code already linked with this particular library, so versioning it is not really an option.

You should take a look at how the RHEL-6 pcp srpm package is built to use access an alternative version papi libraries. It uses the papi-5.1.1 libraries on RHEL-6 without issue.
