Hi All,
On RHEL-6.5 there is are two version of papi available: papi-4.1.3 for
compatibility and papi-5.1.1 for newer features. For compatibility reasons the
papi-4.1.3 is the one generally visible to configures by default. The problem
is that the pcp configuration find the older 4.1.3 version rather than the
shiny new papi-5.1.1. I have been hacking away on on the pcp configuration to
allow specifying an alternative directory for papi. There are certainly things
wrong with the patch (like it doesn't verify that includes and libraries are
really in that directory), but it does allow selection of the papi-5.1.1
directory. Suggestions on how to better handle this would be appreciated.
Maybe have separate options to specify include and lib diretories. Note that a
similar patch might be desired for the perfevent pmda because there is a newer
version of libpfm associated with papi-5.1.1 on rhel6.
Default build shows libpapi-4.1.3 being used:
$ ./configure --with-papi
$ make
$ ldd src/pmdas/papi/pmda_papi.so
linux-vdso.so.1 => (0x00007fffed675000)
libpapi.so => /usr/lib64/papi-4.1.3/libpapi.so (0x00007f5c0b630000)
libpcp_pmda.so.3 => not found
libpcp.so.3 => not found
libdl.so.2 => /lib64/libdl.so.2 (0x00007f5c0b42b000)
libc.so.6 => /lib64/libc.so.6 (0x00007f5c0b097000)

/lib64/ld-linux-x86-64.so.2 (0x0000003143400000)
Configure and build specifying the papi-5.1.1 shows papi-5.1. being linked in:
$ make clean
$ ./configure --with-papi=/usr/lib64/papi-5.1.1/usr
$ make
$ ldd src/pmdas/papi/pmda_papi.so
linux-vdso.so.1 => (0x00007fff3ecf2000)
