GCC 6.2 toolchain for AmigaOS 3
https://github.com/bebbo has ported cross-compiler toolchains for Windows, Linux and Mac OS. I have not tried them yet but it's a very recent version of GCC.

Nice! Finally a more recent version of GCC. I'll give it a go!

I tried to build this last week. Run into a couple of problems I couldn't solve.
I made some notes, which I was intending to post after I got everything working: 1. The page has: # git clone git://github.com/cahirwpz/amigaos-cross-toolchain.git But this should be: # git clone git://github.com/bebbo/amigaos-cross-toolchain.git otherwise you will build gcc 2.95 like me :-) 2. You are going to need 32bit gcc and libs (anyone know why?). Didn't keep all my notes but I needed at least these: sudo apt-get install libgmp-dev:i386 libmpfr-dev:i386 libmpc-dev:i386 gcc-multilib g++-multilib 3. Don't forget the "--gcc 6" parameter! It says it right at the top of the page but wasn't obvious to me. 4. You need a github account with a ssh key! I think this is because the scripts use ssh:// instead of https:// (which shouldn't be necessary for a RO checkout). You can add a key here: https://github.com/settings/ssh After all this I get 2 errors. Code:
/usr/bin/install: cannot create regular file '/home/paul/source/gcc6.2/amigaos-cross-toolchain/.build-m68k/host/man/man1/flex.1': No such file or directory Makefile:180: recipe for target 'install.man' failed GCC actually builds OK but libnix fails. submodules/libnix/sources/stubs/../nix/misc/__request.c Code:

Seems to be a problem with the inlines or protos:
Code:
#include <proto/dos.h> void test() { Open("",MODE_OLDFILE); } Code:

This is from gcc3.4.0
Code:
void test() { ({ CONST_STRPTR _Open_v1 = (""); LONG _Open_v2 = (1005); BPTR _Open_re2 = ({ register int _d1 __asm("d1"); register int _a0 __asm("a0"); register int _a1 __asm("a1"); register BPTR _Open_re __asm("d0"); register void *const _Open_bn __asm("a6") = (DOSBase); register CONST_STRPTR _n1 __asm("d1") = _Open_v1; register LONG _n2 __asm("d2") = _Open_v2; __asm volatile ("jsr a6@(-""0x1e"":W)" : "=r" (_Open_re), "=r" (_d1), "=r" (_a0), "=r" (_a1) : "r" (_Open_bn), "rf"(_n1), "rf"(_n2) : "fp0", "fp1", "cc", "memory"); _Open_re; }); _Open_re2; }); } Interestingly enough, the 6.x says that a0,a1 are clobbered and 3.x does not.

Tested 2.95 vs 6.20 and they both produce identical code for the Open() wrapper.
I wonder if fd2sfd needs work? I don't think Debian is an issue but I will spin up a 32bit Ubuntu VM just in case. The compiler is working but OS support would be useful :-) |

Mac has the same issue, so I doubt it's the OS. Would be nice if we could get the author to this thread so he's aware.

... committed it without testing 2.93. Then the libnix will build partially. Relative code is not yet working. Last edited by bebbo; 10 January 2017 at 00:35. |

The latest commits made it go much further for me on Debian!
EDIT: I do get a lot of these: Code:

As long you are not using the -fbaserel option you should be able to compile and link Amiga executables now. |

I don't feel like the whole toolchain has successfully been compiled though, and I get funky stuff like this when trying to compile the example files that did compile with gcc-2 Code:

No one said it's a release version.
If I have time I'll continue working on building libnix without errors. |

Thanks Bebbo :-) I didn't realise you are on this board. I will have a play.

Late home today due to a train drivers strike in Southern England. 2 hours to get home from work :-(
This seems to be the cause of the problems. Error: Unknown pseudo-op: `.section' Confirmed that m68k-amigaos-as does not support .section Example: Code:
paul@debian:cd ~/source/gcc6.2/amigaos-cross-toolchain/submodules/libnix/sources/stubs/stubs /opt/m68k-amigaos/bin/m68k-amigaos-gcc __dtor_list__.c /tmp/cctMPpYM.s: Assembler messages: /tmp/cctMPpYM.s:3: Error: Unknown pseudo-op: `.section' /opt/m68k-amigaos/bin/m68k-amigaos-gcc -S __dtor_list__.c cat __dtor_list__.s #NO_APP .globl ___DTOR_LIST__ .section .bss .align 2 ___DTOR_LIST__: .skip 8 Thanks for the great work Bebbo, we appreciate it :-) |
