I recently posted a note to this group that I had succeeded in getting g++-1.37.1 to work on the decstation. Several people asked for diffs and explanations, but about half my replies bounced. Here is the text of my response to one query. (Ultrix 3.1, 12 Mbyte) ...I'm happy to supply the changes I made, though. You do need gcc 1.37.1, of course. Fortunately, it installs completely without a hitch, as usual (quite an accomplishment). First, get g++ 1.37.0 and the patch to bring it up to 1.37.1, (and apply the patch). Second, create the various links described in the README, run congif.g++ decstation, etc. Then apply the Makefile patch; this isn't a bug fix, it is just the result of my editing the Makefile to configure it for the decstation. After applying this patch, you will probably want to make sure that the Makefile installation paths are set up for what you want. Now type "make". The make will chug along for quite a while, but will eventually stop when it attempts to compile aux-output.c. There is a declaration conflict from an include file, which I corrected by just commenting out the declaration from aux-output.c, relying upon the existing extern declaration from tree.h. Without really understanding the problem, this seems to fix it. Unfortunately, you have to do the patch in two steps, because aux-output.c doesn't exist until after the make starts. I'm not really sure where it comes from---so I patch when make fails. After applying this patch, type "make" again, and it should go to completion. I didn't have to do anything to it after the aux-output.c patch. I did compile up libg++, and it went just fine. %%%%%%%%%%%%%%%%%% apply this patch to Makefile %%%%%%%%%%%%%%%%%%%% 41c41 < COFFLAGS = -DUSE_COLLECT -DEXTENDED_COFF -DNO_UNDERSCORES --- > # COFFLAGS = -DUSE_COLLECT -DEXTENDED_COFF 49c49 < CFLAGS = -DGATHER_STATISTICS -O $(COFFLAGS) -B../gcc-test/ --- > CFLAGS = -g -DGATHER_STATISTICS -O $(COFFLAGS) -B../gcc-test/ 323c323 < CRT1_COMMAND=$(CC) -Um68k -c $(INCLUDES) crt1.c --- > CRT1_COMMAND=$(CC) -Um68k -g -c $(INCLUDES) crt1.c %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%% apply this patch to aux-output.c after the Make halts %%%%%%%%%%% 467,468c467 < /* the following line conflicts with a declaration in tree.h */ < /* extern char *tree_code_name[]; */ --- > extern char *tree_code_name[]; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Good luck, -john (607 255 8298) John Sahr, | Electrical Engineering - Space Plasma Physics johns@alfven.spp.cornell.edu | Cornell University, Ithaca, NY 14853 -- John Sahr, | Electrical Engineering - Space Plasma Physics johns@alfven.spp.cornell.edu | Cornell University, Ithaca, NY 14853
