I'm running RHEL 5 Server i386 on i686 hardware, so as far as I know it
isn't a 32/64 bit issue.
# uname -p
i686
# rpm -q --queryformat="%{NAME}-%{VERSION}-%{RELEASE}\t%{ARCH}\n"
cfengine
cfengine-2.2.1-1.el5.rf i386
If the complete ldd output or nm output of the working and non-working
binaries is of any value, let me know.
One difference I did see with "ldd -v" is that the non-working binary
contains:
/usr/sbin/cfagent:
...
libc.so.6 (GLIBC_2.4) => /lib/libc.so.6
This was not present in the working binary compiled from source or SRPM.
For those, "ldd -v" looks like:
/usr/sbin/cfagent:
libm.so.6 (GLIBC_2.0) => /lib/libm.so.6
libpthread.so.0 (GLIBC_2.2) => /lib/libpthread.so.0
libpthread.so.0 (GLIBC_2.0) => /lib/libpthread.so.0
libc.so.6 (GLIBC_2.1.1) => /lib/libc.so.6
libc.so.6 (GLIBC_2.3) => /lib/libc.so.6
libc.so.6 (GLIBC_2.3.4) => /lib/libc.so.6
libc.so.6 (GLIBC_2.2) => /lib/libc.so.6
libc.so.6 (GLIBC_2.1) => /lib/libc.so.6
libc.so.6 (GLIBC_2.0) => /lib/libc.so.6
If this isn't worth investigating any further, I'm content rebuilding
from SRPM.
Thanks!
