To: info-iris@brl.mil 23-Dec-1990 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.
