I am looking over all the native code in TPTP looking to adapt the 32bit |
linux version for 64bit linux. Given that other architectures that TPTP
runs on are 64bit I figure most of the hard work has already been done
with porting to 64bit platform (in relation to writing portable code
pointer/long type size changes) and its just a matter of someone
building the native parts and resolving the issues.
I am trying to build the old agent controller as per the instruction in
There appears to be some magic number added to the data to describe the
native host platform. However I would guess that 32bit and 64bit linux
should have different magic values, the following piece of code adds
that number but there is no allocation for __x86_64__ (the commented out
defined(__x86_64__) was added by me to asses how much work as needed to
make it compile.
So if I hunch is correct can someone tell me what value I should be
using for 64bit Linux here.
#elif defined(__linux__) && (defined(__i386__) /*|| defined(__x86_64__)*/)
#elif defined(__linux__) && defined(__s390__)
#elif defined(__linux__) && defined(__powerpc64__) || defined(_WIN64)
/*ts. bug 120479*/
/* traceWriteInt32LittleEndian(99); */
#error "unknown platform"
The code then goes on to write out classID information which I guess is
64bit on 64bit platforms, but the current code path truncates it into a
32bit piece of data. I guess the OS400 platform is 64bit so can anyone
confirm if I can use this method for 64bit Linux as well ?
Where is the code that reads the data, does that code need adjusting to
decode the data correctly ?
