Description Eugeniy Meshcheryakov 2006-09-17 18:57:16 UTC 
After configuring and building with --enable-perfmon:

% readelf -d /usr/bin/stap | grep NEEDED
 0x00000001 (NEEDED)                     Shared library: [libpfm3.so.3]
 0x00000001 (NEEDED)                     Shared library: [libelf.so.1]
 0x00000001 (NEEDED)                     Shared library: [libstdc++.so.6]
 0x00000001 (NEEDED)                     Shared library: [libm.so.6]
 0x00000001 (NEEDED)                     Shared library: [libgcc_s.so.1]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]
% readelf -d /usr/bin/lket-b2a | grep NEEDED
 0x00000001 (NEEDED)                     Shared library: [libpfm3.so.3]
 0x00000001 (NEEDED)                     Shared library: [libglib-2.0.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]
% readelf -d /usr/lib/systemtap/stpd | grep NEEDED
 0x00000001 (NEEDED)                     Shared library: [libpfm3.so.3]
 0x00000001 (NEEDED)                     Shared library: [libpthread.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]

But only stap binary actually uses libpfm.

This was fixed incidentally to the suspension of the perfmon code in the
translator.  Once it returns, we'll make sure that such LIBS are
kept to the appropriate binaries.
