C program scheduler

AntBark — Mon, 08 Dec 2003 04:41:00 GMT

I recently upgraded from a D320 server to a B1000 workstation - From HPUX 10.2 to HPUX 11.00, and probably more important from 32 to 64 bit. Oracle 8.1.6 64 bit was also installed. Had some minor hickups but everything went fine untill I tried moving my C applications. All applications compiles fine on the new system - The problem though: I have got a program scheduler developed in C which doesn't operate correctly - no errors or crashes but it doesn't do what it is suppose to. I've used this scheduler on several other machines - only difference is that this is a workstation and 64 bit. Basically the program uses pstat_getproc, and execv to monitor and schedule programs. The program runs but doesn't get anywhere ??? Any suggestions ?
Thank you

There's a note on 32/64 bit compatibility in the man page.

Try compiling with -D_PSTAT64

Thank allot Graham - helped alot!

I got this error eventially :
cpp: "/usr/include/sys/stdsyms.h", line 297: error 4062: "wide mode pstat interfaces not supported in strict ANSI mode."

Does this mean I may never use -Aa in my compilation when using -D_PSTAT64 ?

cheers

Try "cc -Ae" instead of "cc -Aa". Strict
ANSI mode (-Aa) is indeed quite strict. I've
always found -Ae to be more useful.
