Hi All, 
having managed to successfully installed sudo (sudo-1.8.21p2-1) from https://www.ibm.com/developerworks/aix/library/aix-toolbox/alpha.html#S on aix 6.1 (6100-07-05-1228)

the executable  fails to run due to a missing symbol from libc.a. 

#> sudo -l

exec(): 0509-036 Cannot load program sudo because of the following errors:

        0509-130 Symbol resolution failed for /opt/freeware/libexec/sudo/libsudo_util.so because:

        0509-136   Symbol memset_s (number 100) is not exported from

                   dependent module /usr/lib/libc.a(shr.o).

        0509-026 System error: Error 0

        0509-192 Examine .loader section symbols with the

                 'dump -Tv' command.

Using the dump command to inspect the shared lib, the libc.a library is indeed missing the memset_s symbol / function. 
Checking on the libc.a on another AIX box (AIX7.1), the symbol is found. 
 

Will patching the AIX 6.1 to the latest patch level or technology level help here ? 
Any other ways to resolve this besides patching the system ? 

Much thanks in advance

I don't see any other way to resolve this.
