Porting programs from SGI to IBM R6000
We are facing a peculiar situation where we havn't seen a IBM Risk 6000
machine yet but are asked to port programs from SGI 4D70GT and 4D25TG machines
to a remote IBM R6000 machine within a day or so using magnetic tape. The IBM
has a so-called 3D-adapter along with a z-buffer and supports the SGI GL.
That's all we know. Questions are:
- Regarding 'tar', is the IBM byte or word or byte+word swapping
when 'tar' is invoked ? Any precautions to take when archiving
SGI programs by means of 'tar' and attempting to extract the
archive on the IBM machine ?
- What changes are to be expected regarding the make files ?
A typical makefile for our programs is:
SHELL=/bin/sh
PROGS= gener sectors times
LDFLAGS = -lgl_s -lm -lfm_s -lbsd
CFLAGS = -O -I/usr/include/gl -I/usr/include/bsd
all: $(PROGS)
.c:
$(CC) $(CFLAGS) -o $@ $< $(LDFLAGS)
- What problems are to be expected on the IBM machine for a highly
interactive multiple window program making heavy use of event
queuing ?
- Any other traps we might encounter ?
Admitting that this is a rather peculiar situation I would appreciate any
comments which might be usefull.
Thanks in advance and season's greetings.
