Some problems you might encounter: * GNU sed 1.06 cannot handle the sed script in mf/convert. * On a 386 machine, GNU C 1.36 does not compile tex.5 correctly when making a 32-bit TeX. 1.37 fixes this bug. * GNU Make 3.57 does not pass arguments to shell scripts (like convert), under system V. 3.56 does not have this problem, and neither does 3.58. * On the AT&T 3b2, under System V release 3.2, cc thinks that eject_penalty (which is -1000, defined at line 3216), is a very large positive number. * On a Sun 386i running 4.0.1, cc cannot compile Metafont with -O, because it can't compile x = x + y correctly. Don't use -O, or don't use cc. * Some parts of this work on an Apollo, other parts don't. Ditto for an Amiga. bsuggs@hac2arpa.hac.com is working on this, but would be happy to have help. * On a 386 machine running 386/ix, cc cannot compile itex.c, according to Reiner Petersen . Here is an ed script to get around the problem (alternatively, you can get gcc, and compile with that): : # Reiner Petersen (reiner@coma.uucp) # Technical University of Berlin # ed - $1 << end-of-edscript !echo change: / register integer for_end; i = 1 ; for_end = 31 ; if ( i <= for_end) do +1,.+2p -2,.c register integer for_end; register char j; /* 386/ix cc bug workaround rp */ i = 1 ; for_end = 31 ; if ( i <= for_end) do j = i; xchr [ j ] = chr ( i ) ; while ( i++ < for_end ) ; . !echo to: -8,.p w $1 end-of-edscript If you want, you can put this into the pipeline in ./tex/convert. * undump doesn't work under 386/ix. Here is a diff to undump.SYS_V.c to fix the around, again contributed by reiner: *** undump.SYS_V.c Mon Apr 20 00:57:23 1987 --- undump.c Fri Aug 19 17:55:27 1988 *************** *** 1,7 **** /* * undump - resurrect a core file into a running program. * ! * for UNIX System V on a 3Bx * that uses the Common Object File Format * * Author: --- 1,7 ---- /* * undump - resurrect a core file into a running program. * ! * for UNIX System V on a 3Bx or Interactive 386/ix * that uses the Common Object File Format * * Author: *************** *** 9,14 **** --- 9,19 ---- * New York University * Tue Mar 3 13:18:25 EST 1987 * + * Additions for 386/ix: + * Reiner Petersen (reiner@coma.uucp) + * Technical University of Berlin + * Thu Aug 18 13:40:20 MET DST 1988 + * * Adapted from: * Spencer Thomas's undump and the file unexec.c in GNU emacs */ *************** *** 15,22 **** --- 20,33 ---- #include #include + + #ifndef ISC_386ix /* not availible in ISC 386/ix */ + #include #include + + #endif /* ISC_386ix */ + #include #include #include *************** *** 37,46 **** --- 48,66 ---- struct scnhdr dsc; struct scnhdr bsc; + #ifdef ISC_386ix + struct scnhdr csc; /* Comment section used by ISC 386/ix */ + #endif /* ISC_386ix */ + long bias; long lnnoptr; long text_scnptr; long data_scnptr; + + #ifdef ISC_386ix + long comment_scnptr; + #endif /* ISC_386ix */ + long symlocptr; main(argc, argv) *************** *** 89,94 **** --- 109,118 ---- dsc = sc; else if (strcmp(sc.s_name, ".bss") == 0) bsc = sc; + #ifdef ISC_386ix + else if (strcmp(sc.s_name, ".comment") == 0) + csc = sc; + #endif /* ISC_386ix */ *************** *** 97,103 **** if (u.u_exdata.ux_tsize != aout.tsize || u.u_exdata.ux_dsize != aout.dsize || u.u_exdata.ux_bsize != aout.bsize) ! fprintf("mismatch between %s and %s sizes\n", a_out_name, core_name); exit(1); --- 121,128 ---- if (u.u_exdata.ux_tsize != aout.tsize || u.u_exdata.ux_dsize != aout.dsize || u.u_exdata.ux_bsize != aout.bsize) ! fprintf( stderr, "mismatch between %s and %s sizes\n", ! a_out_name, core_name); exit(1); *************** *** 122,128 **** --- 147,159 ---- bsc.s_paddr = bsc.s_vaddr = aout.data_start + aout.dsize; bsc.s_size = aout.bsize; bsc.s_scnptr = 0L; + #ifndef ISC_386ix bias = dsc.s_scnptr + dsc.s_size - lnnoptr; + #else + comment_scnptr = csc.s_scnptr; + csc.s_scnptr = dsc.s_scnptr + dsc.s_size; + bias = csc.s_scnptr + csc.s_size - lnnoptr; + #endif /* ISC_386ix */ if (fh.f_symptr > 0L) fh.f_symptr += bias; *************** *** 139,149 **** --- 170,186 ---- Perror("ds write"); if (fwrite(&bsc, sizeof(bsc), 1, nfp) != 1) Perror("bs write"); + if (fwrite(&csc, sizeof(csc), 1, nfp) != 1) + Perror("cs write"); fseek(nfp, (long)text_scnptr, 0); copy(afp, nfp, aout.tsize); fseek(cfp, off, 0); fseek(nfp, (long)data_scnptr, 0); copy(cfp, nfp, size); + #ifdef ISC_386ix + fseek(afp, (long)comment_scnptr, 0); + copy(afp, nfp, csc.s_size); + #endif /* ISC_386ix */ copy_syms(afp, nfp); fclose(nfp); fclose(afp);
