Further to my previous posting, I have now put a quantity of gcc binaries and patches for MINIX/68k on plains.nodak.edu (Thanks Glen !!) They are rooted in pub/Minix/uk/mincen/68k/gcc, with some other goodies lying around in directories at the same level, including binaries for TeX. I have provided binaries and patches for gcc-1.39 and gas-1.37. Binaries are also present for flex-2.3.6 and bison-1.12; you need bison to recompile gcc. A complete set of libraries for both 16 and 32-bit compilation are included. Please note that this is my flavour of gcc-1.39, rather than CvW's, so it doesn't contain his patches for sizeof(). Nothing personal here - the tar file was on its way to plains before I saw his patches, otherwise I would have included them. I will include them next time, because they save having to cast several sizeof's in the MINIX-1.5 kernel sources. Here is the README file from pub/Minix/uk/mincen/68k/gcc. ---------------------------------------------------------------------------- This is a collection of gcc and other gnu utilities for MINIX-68k. All were current versions at the time of assembling this archive. The main constituents are gcc-1.39 and gas-1.37, but flex, bison and gnu diff are included as well. The diffs for gcc and gas are based on those originally devised by Jhawar Bammi, to whom I am eternally grateful ! My changes to his work are as follows: (a). The root of the gnu tree is now /usr/gnu, rather than /usr/local. My /usr/local directory got rather full, and /usr/gnu was suggested by the author of bash. This means that the contents of the enclosed bin directory should be copied to /usr/gnu/bin, and the lib directory to /usr/gnu/lib. Remember to put /usr/gnu/bin in your $PATH. If you want to use a different directory structure, you will have to alter the patches and recompile. (b). Bammi's original mods included provision for gcc under TOS. I have removed all these modifications for the sake of readability as much as anything else. The Makefiles still support cross-compilation; define NATIVE_MINIX or CROSS_MINIX as desired. I havn't tested the cross compilation option since gcc-1.37.1. (c). Bammi removed the 68881 and 68851 code generation from gas. I have replaced it due to the likelihood of gcc running on Amigas with '020 and '030 processors. Note that this code won't be generated unless you actually ask gcc or gas to do it, so there is no problem on 68000s. (d). I have made gcc compatible with MINIX-1.5 include files and libraries. This obviates the need for an entirely separate gcc-include directory, because gcc will now work with (patched) MINIX-1.5 include files. I have therefore altered bammi's patches for the include directory back to the normal behaviour, i.e. gcc will look in /usr/include unless a file already exists in the directory /usr/gnu/lib/gcc-include. I have altered the MINIX-1.5 <curses.h> to the BSD version supplied with bammi's gcc. The appropriate curses libraries are therefore enclosed as well. Note that there also two versions of gcc-ar, one for 1.5 and one for earlier versions of MINIX. As several people have discovered, the pre-1.5 gcc-ar won't run under MINIX-1.5. Since the 1.5 version only requires recompilation with the later libraries, my diffs for gcc-ld aren't any different to bammi's other than for changing the gcc root directory. I therefore havn't bothered to include them. I have included Fred Fish's pml maths library, with slight alterations for MINIX-1.5. I'm not entirely convinced that all is well with the gcc floating point; I will have a look when I get the time (joke !) This version of gcc should work quite happily on the Amiga, although I havn't yet had the chance to test it. I suspect that the Mac probably uses rather different libraries, so you might have problems. Then again, you might not. If you want to re-compile gcc, you will need a machine with about 2.5Mb of ram. To re-compile gas, you need 4Mb - the file m68k.c is huge, and takes a 4Mb STE about 14 minutes to compile ! Enjoy !!
