Missing link for Basilisk I found

Posted on by
Reply

Actually I held onto this, as I wanted to do something crazy for that Marchintosh thing but life got in the way it fell by the wayside, and well now it’s September, and I already have a Qemu instance running A/UX so my ‘at best’ hope of Basilisk II with MMU emulation is all but moot.

Captain, oh Captain!

While it may look like 2 very old emulators, which they are, the interesting thing here is that this old version of Basilisk that only has Macintosh Classic emulation is using the 68000 emulation core from UAE 0.6.8. It took a lot of downloading stuff, a lot of other nonsense, but I eventually found it, and was able to diff around to find the changes made were rather inconsequential, there by letting me rebuild UAE back on top of Basilisk.

My plan had been to either use far newer UAE cpu core, say from Previous as it has working MMU support, or Musashi.

I was building hard coded for TDM GCC 5.1.0 on MinGW. It doesn’t matter anymore but I threw it up on github since that is where all the cool kids are.

It’s absolutely pointless I guess, but maybe someone will find it interesting.

Cockatrice III 0.5a update

Here’s to US!

Well this is a ‘small’ update, but with a big change, the audio is for the most part working great now thanks to this fix from rakslice. Namely changing SDL to MSB:

desired.format = AUDIO_S16MSB;

And another MinGW tweak, and yeah it’s GREAT!

Even stuff like RealAudio work now! I’ll add some self hosted video later as it’d just get struck from anything public.

Also since the RealAudio player is timebombed for installing, I added some lazy offset to remove however many billions of ticks from the clock letting you jump in some random point in the past when it won’t care.

I guess the final if any justification for a bump would be rebuilding with GCC 8.1.0 on MinGW. I somehow butchered the slirp.h to make it too MinGW’ish so it won’t clean build on Linux or OS X, but I have re-butchered a private branch and it works.. I just need to merge and clean but I’m not in the mood at the moment.

I could be crazy but it “feels” faster.

At any rate, I found that System 7 is more agreeable to running Return to Zork, just use some toast image mounter from within MacOS, and it’ll run!

Also there is some ULONGLONG weirdness going on, so I had to backout Peter’s changes for larger disks. No doubt some standard type thing change in GCC 8.

Couldn’t reserve space for Cygwin’s heap

Posted on by

I have this old toolchain that relies on MSYS 1.0 from 20+ years ago. It’s great. I know others always love the newer, but I’m happy with this one.

Well this morning I wanted to rebuild some Qemu 0.90 thing and I got this fun error trying to run configure:

      0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x71110000, RegionSize 0x440000, State 0x10000
d:\mingw\msys\bin\bash.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0

What the heck?! MSYS uses cygwin? I guess I should have known. So the solution is to ‘rebase’ the DLL, as it tries to take a static ‘grab’ at some memory block, because…. I guess subsystems or loaded DLL’s suck?

I rebooted and got the same error.

So obviously it’s a lot more involved.

So looking the rebase I have is part of the Platform SDK. Maybe there are others.

D:\MinGW\msys\bin>"D:\MinGW\include\directx\Microsoft Visual Studio 8\VC\PlatformSDK\Bin\rebase" -b 0x50000000 msys-1.0.dll

REBASE: Total Size of mapping 0x0000000000110000
REBASE: Range 0x0000000050000000 -0x0000000050110000

And now I can run stuff again. YAY.

I’m sure this has been covered time and time again, but you know it’s mostly to remind me in another 20 years.

MinGW and missing DLL’s

Posted on by

UGH

Stuff like this drives me crazy.  Once upon a time everything was statically linked, there were no DLL’s, and all exe’s had a lot of the same code in them, and people realized that the majority of a hard disk could literally contain the same thing over and over.  Not to mention that if you were to fix some bug in say, LIBC you would have to re-compile everything.  So we entered the brave new world of dynamic linking where we now live in the proverbial DLL hell, that although we did save space, we have things where slight variations in the same DLL can break things in unforeseen ways.  People have tried various things such as weak linking, Side by side assemblies, Frameworks, and all kinds of things to try to keep things together.

Honestly it’s just easier to go back, and statically link things, and just re-build as needed.

common culprits of MinGW based stuff always include:

  • libwinpthread-1.dll
  • libgcc_s_dw2-1.dll
  • libstdc++-6.dll

ugh.

The hard one is the pthread library.  If you try to link it statically it’ll try to link everything else statically and not every DLL can link statically (SDL* keep reading).  But GCC / Binutils does have the option to turn various features on and off through the link string

-static-libstdc++ -static-libgcc -Wl,-Bstatic -lstdc++ -lpthread -Wl,-Bdynamic

As you can see, everything after “-Wl,-Bstatic” will be linked statically, while everything after “-Wl,-Bdynamic” will go back to being dynamically linked.

Ok, that is great but what about SDL, you may ask.  Well sure it’s a DLL, but even DLL’s come from somewhere.  Download the source, build it yourself and you can directly link the objects that make up the DLL.  In version 1.2.15 they live in the .libs directory.

SDL-1.2.15\build\.libs\*.o

And on Windows, if you get weird errors like:

SDL_dx5events.o: In function `DX5_DInputInit’:
SDL-1.2.15/./src/video/windx5/SDL_dx5events.c:183: undefined reference to `IID_IDirectInputDevice2A’

Just add the -ldxguid library and you can link this too.  I’m sure once upon a time people may not have had DirectX 5 or higher, but this isn’t 1997.

And please at least test your programs with no path, so that way you are aware of what is needed for re-distribution.

set path=.
D:\dosbox-code-0-4068\dosbox\trunk\src>dosbox.exe

DOSBox SVN

It gets so old when people never test.  And people freak out trying to download DLL’s from weird sites, and you know that never ends well.

Oh yeah, and a static version of DOSBox is 4MB.

4,033,550 dosbox.exe

I know that was massive a long long time ago, but today?

Porting Catacomb3D to MS-DOS (DJGPP v1/GO32).

Catacomb 3-D for GO32

No really, it’s Catacomb 3-D: The Descent.  First ported to 32-bit SDL by NotStiller.  Me being the person I am, I fixed a slight bug regarding binary files on Windows, and MS-DOS, then cleaned up some of the C++ syntax (yuck!) making it far more C89 friendly.  And of course, hot off the heels of DooM for GO32 DPMI, I was able to get it to build and run using GCC 1.39 and GO32.

I know most people really won’t care, but I found it kind of interesting.  I should try to see if it’ll run on actual hardware, just as a comparison of tightly optimized Borland C++ / Assembly vs 100% pure C on DJGPP.  The best tech of 1991 for sure!

At current I just put the source up, you can git it here.

26th anniversary of Linux!

As the joke goes:

Happy 25th birthday, Linux! Here’s your f-ing cake, go ahead and compile it yourself.

So it’s always a fun time for me to push my old project Ancient Linux on Windows.  And what makes this so special?  Well it’s a cross compiler for the ancient Linux kernels, along with source to the kernels so you can easily edit, compile and run early Linux from Windows!

As always the kernels I have built and done super basic testing on are:

  • linux-0.10
  • linux-0.11
  • linux-0.12
  • linux-0.95c+
  • linux-0.96c
  • linux-0.97.6
  • linux-0.98.6

All of these are a.out kernels, like things were back in the old days.  You can edit stuff in notepad if you so wish, or any other editor.  A MSYS environment is included, so you can just type in ‘make’ and a kernel can be built, and it also can be tested in the included Qemu.  I’ve updated a few things, first with better environment variables, and only tested on Windows 10.  Although building a standalone linux EXE still requires a bit of work, it isn’t my goal here as this whole thing is instead geared around building kernels from source.  I included bison in this build, so more of GCC is generated on the host.  Not that I think it matters too much, although it ended up being an issue doing DooM on GCC 1.39.

So for people who want to relive the good old bad days of Linux, and want to do so from the comfort of Windows, this is your chance!

WSAPoll & MinGW

Posted on by

For some reason if you try to use WSAPoll, you’ll get this fine error on linking:

poll.c:(.text+0x26): undefined reference to `WSAPoll’

Yeah.

Turns out that it’s basically missing from the includes.  Thanks to this hint, just simply add this into your source/header after pulling in winsock2.h and it’ll link.

typedef struct pollfd {
SOCKET fd;
SHORT events;
SHORT revents;
} WSAPOLLFD, *PWSAPOLLFD, FAR *LPWSAPOLLFD;
WINSOCK_API_LINKAGE int WSAAPI WSAPoll(LPWSAPOLLFD fdArray, ULONG fds, INT timeout);

And now you can happily compile and link.

Just for you, lucky Spanish user, GCC 3.0.4 for Windows NT (MinGW)

I cannot understand why you want this, or why I’m even going to do it.  At this point in GCC history the winnt-3.5 target had been dumped in favour of going all in with Cygwin.  So yeah, this does not either clearly configure, or compile.  But a little bit of mashing files, and I have it at least compiling some assembly that can be translated into an object file that a later version of MinGW can actually compile.

N64 cross GCC / Binutils for Win32

Posted on by

Building GCC & Binutils for the Nintendo 64

I had a request to help get a GCC+Binutils running as native win32 exe’s something comperable to the ancient ‘ultra’ N64 toolchain done by Kyoto Microcomputer (resume pdf).  One interesting thing about their toolchain is that they used a common object format for MS-DOS, DOS/V and MS-DOS on the PC-98 format, along with Win32.  However the Win32 runtime doesn’t like Win64 environments.  On Win64 the exew32 driver just complains:

Can’t allocate memory (Error Code=487)

However the stubs in all the exe’s reference exegcc98 exegccv DOS extender’s along with a exegcc.  However googling around yields nothing.

Running on a x86 version of Windows, however the tools run and report gcc 2.7.2 release 1.2 and the binutils version is simply 2.6 with BFD version 2.6.  So going with this, and the request to keep it 1997 vintage I went ahead with Gcc 2.7.2.3 and Binutils 2.8.1 as they are the end of the line in both trains of code.

To configure is really a snap, as both support the Windows NT platform directly

sh configure --host=i386-winnt3.5 --target=mips-elf

I guess I should add that I build with TDM GCC 5.1, and I use the incredibly ancient MSYS-1.0.11-rc-1.  But it’s enough to bootstrap and build with!  Since my GCC is much newer, I did have to finagle some things.  Here is a quick list of my notes on what I had changed, and some justification.

Binutils 2.8.1 notes:

include/fopen-same.h

make sure this uses MS-DOS rb wb type constraints!

libiberty/xmalloc.c

There is no sbrk on my MinGW32 … so comment out all the sbrk stuff.

bfd/targmatch.sed

My sed LOVES UNIX style text files, so this one shouldn’t be in MS-DOS CRLF format.

binutils/objcopy.c

mkdir only accepts the path on Win32.  Also there is now chown.

Gcc 2.7.2.3 notes:

c-gperf.h

‘__inline’ for is_reserved_word needs to be commented out.

config/mips/mips.h

Set like the following for both ASM_FINAL_SPEC to prevent the t-mips from trying to be run.

#define ASM_FINAL_SPEC “\
+%{pipe:-}”

config/winnt/xm-winnt.h

OBJECT_SUFFIX “.o”

Just because we are on Windows NT, doesn’t mean we want an .obj object suffix.

gcc.c

__spawnv : __spawnvp work better as _spawnv : _spawnvp

obstack.h

*((void **)__o->next_free)++ = ((void *)datum);

confuses newer compilers, with this error message:

obstack.h:341:32: error: lvalue required as increment operand

replace it with with:

*(__o->next_free)++ = ((void *)datum);

So at the end I have a cross compiler, and I can generate object files, and link files that the final tool MILD can then use and produce N64 ROM images.  It’s not a 100% solution, as I don’t see any mention of MILD being GNU, however the compiler and binutils is running on Windows 10 x64!

GCC cross compiling to the N64 target

GCC cross compiling to the N64 target

I built a few demos and tested with the 1964 emulator.

And there you have it.  For anyone who cares, you can download the toolchain + source here: winnt3.5_i386-mips_elf-gcc-2.7.2.3_binutils-2.8.1.7z

Stupid GCC error

Posted on by

So while mixing and matching GCC on Windows, I ran into this issue with stdio.h of all things:

In file included from hi.c:1:0:
\mingw\include/stdio.h:191:65: error: unknown type name ‘size_t’
_CRTIMP int __cdecl __MINGW_NOTHROW setvbuf (FILE*, char*, int, size_t);
^~~~~~

Good grief how could stdio be all screwed up?

Well, it turns out it was my fault.  I had not rebuilt things like SDL, or copied over pcap so I figured I could incorrectly just point a -I to my old includes, and the new gcc would post-pend all use -I stuff.  NOPE it pre-pends them, meaning the old headers now take priority.  And wouldn’t you know it, things have drifted between versions.  So I just manually copied the files and libraries and all was well.

Googling around I did see other people with broken stdio.h but nobody posted the solution.  I guess it’s to embarrassing, but here we are.
