#10 Redhat ES Version 4 x86 64 Bit Ed. Install

[Stanley Ezzell]

Hi,

I have been using the SAPRFC module for a couple
of years now. I am upgrading hardware from an IA32
architecture to the SUN 64bit environment. I feel
comfortable with the install process, but I can't get
past this issue and I can't seem to google anything
regarding this error.

In the /var/log/httpd/error.log file I have an entry
for:
PHP Warning: Unknown(): Unable to load dynamic
library '/usr/lib64/php4/saprfc.so' -
/usr/lib64/php4/saprfc.so: undefined symbol:
_zend_hash_index_update_or_next_insert in Unknown on
line 0

Specs:
Red Hat Enterprise Linux ES release 4 (Nahant Update
3)
Kernel: 2.6.9-34.EL-smp-x86_64
PHP Version 4.3.9
SAP RFCSDK 6.4 Non-Unicode: RFC_23-10003377.SAR

------------------------------------------------------
----------------
Libraries have been installed in:
/usr/sap/saprfc-1.4.1/modules

If you ever happen to want to link against installed
libraries
in a given directory, LIBDIR, you must either use
libtool, and
specify the full pathname of the library, or use the
`-LLIBDIR'
flag during linking and do at least one of the
following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment
variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment
variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to
`/etc/ld.so.conf'

See any operating system documentation about shared
libraries for
more information, such as the ld(1) and ld.so(8)
manual pages.

tmpnam).
