So it's likely that some IBM POWER7 users -may want to install libpfm4 and build oprofile to link with it. For -example, if libpfm4 were installed in /usr/local, the user would invoke -oprofile's configure thusly: - -LDFLAGS="-L/usr/local/lib64" CPPFLAGS="-I/usr/local/include" ./configure - -But if the user happens to also have libpfm3 already installed in /usr, -then the current order of config tests would result in choosing the libpfm3 -library. This logic seems wrong. The configure checking should go from most -recent to older library versions. This patch changes the order of checking -so the libpfm4 library would be found first. - -Signed-off-by: Maynard Johnson <maynardj@us.ibm.com> ---- - configure.ac | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - -diff --git a/configure.ac b/configure.ac -index 3078393..a9b1ee4 100644 ---- a/configure.ac -+++ b/configure.ac -@@ -160,8 +160,8 @@ if test "$HAVE_PERF_EVENTS" = "1"; then - arch="`uname -m`" - if test "$arch" = "ppc64" || test "$arch" = "ppc"; then - AC_CHECK_HEADER(perfmon/pfmlib.h,,[AC_MSG_ERROR([pfmlib.h not found; usually provided in papi devel package])]) -- AC_CHECK_LIB(pfm,pfm_get_event_name, HAVE_LIBPFM3='1'; HAVE_LIBPFM='1', [ -- AC_CHECK_LIB(pfm,pfm_get_os_event_encoding, HAVE_LIBPFM3='0'; HAVE_LIBPFM='1', -+ AC_CHECK_LIB(pfm,pfm_get_os_event_encoding, HAVE_LIBPFM3='0'; HAVE_LIBPFM='1', [ -+ AC_CHECK_LIB(pfm, pfm_get_event_name, HAVE_LIBPFM3='1'; HAVE_LIBPFM='1', - [AC_MSG_ERROR([libpfm not found; usually provided in papi devel package])])]) - PFM_LIB="-lpfm" - AC_DEFINE_UNQUOTED(HAVE_LIBPFM3, $HAVE_LIBPFM3, [Define to 1 if using libpfm3; 0 if using newer libpfm]) --- -1.7.9.7 - |
