ns and getrusage (was: no title)

[Lloyd Wood <L.Wood@surrey.ac.uk>]

jang,

It's not an easily solvable problem; I've run into the same thing.

I can build and use ns 2.1b3 and later snaphots on an Ultra with
Solaris 2.5.1 easily enough, but on a Sparc20 with 2.4 (5.4
Generic_101945-38 sun4m sparc) with the latest daily snapshot:

mem-trace.h: In method `void MemInfo::checkpoint()':
In file included from scheduler.cc:49:
mem-trace.h:61: aggregate `struct rusage ru' has incomplete type and
cannot be initialized
mem-trace.h:62: warning: implicit declaration of function `int
getrusage(...)'
mem-trace.h:62: `RUSAGE_SELF' undeclared (first use this function)
mem-trace.h:62: (Each undeclared identifier is reported only once
mem-trace.h:62: for each function it appears in.)
mem-trace.h:62: confused by earlier errors, bailing out
*** Error code 1
make: Fatal error: Command failed for target `scheduler.o'

daily snapshot of 28 August, grabbed 29 August.


(and running the working Ultra binary on the '20 gets me:

ld.so.1: /user/ccsrnrpg1/eep1lw/ns/ns/ns: fatal: relocation error:
symbol not found: getrusage: referenced in
/user/ccsrnrpg1/eep1lw/ns/ns/ns
Killed)

See:

http://www-mash.cs.berkeley.edu/dist/archive/ns-users/9806/0161.html
for my previous gruntle about this.

Any chance of having another go at fixing mem-trace for portability,
John? Being limited to in-demand machines when we have Sparc20s
sitting idle isn't exactly ideal. 

thanks,

L.
