given that the Sam440ep does not have altivec wouldn't an Altivec optimized binary crash ? (Just a question).

Thank you to all devs involved for this great job !

Interesting, now I shall compile my codes for my Sam and maybe programming some dockies for Sam.

@abalaban

If it doesn't detect Altivec presence, it would crash, yes. The fix is to provide a non-altivec build. Not a 440ep optimised binary. Like I said, there are reasons why 440ep optimisation is useful, but for the most part there is really no point in using it.

"Anyone can build a fast CPU. The trick is to build a fast system." -Seymour Cray

Downloaded installed and everything working, except that I can't seem to build and amiga library (not a sobj a 'proper' amiga one )

I'm getting link errors, along the lines of duplicate _start symbol, and if I use -nostartfiles I get linker errors as the constructors aren't inlcuded.

In my old SDK I was using a specs file based on the one made by Entzila ( I think) for the asobjs package on os4depot, this drew in the needed the files without having to add explicit paths to the start up objects in the make file.

Now the -shared option has been used for making sobjs and I can find an alternate opion mentioned in the docs. Nor can I find the new specs file to have a butchers at it. (I suspect there aint one)

What am I missing?

Works here with my Commander.blanker but I don't know if it qualifies as a "shared" library.

It compiles with: CFLAGS = -D__NOLIBBASE__ -D__NOGLOBALIFACE__
And links with: LINK = -nostartfiles -lm

Not sure that's any help though.

I think the problem may be that I'm using clib2 threadsafe for my library. And the calls to _lib_init() need the constructors, thus nostartfiles removes to much.

I may be behind the times though can you use newlib for shared libraries these days?

I think the issue would not occur with alibrary that solely used dos.library etc but as I need to link againstt things like libjpeg I need a C-library as well.

There are no problems when using newlib for shared libraries, I do that with dopus.library. Here's a code snippet I think Joerg posted somewhere about using newlib with amiga type .libraries:

Quote:

struct Interface *INewlib; struct ExecIFace *IExec; BPTR g_seglist; static struct Library *LIB_Init(struct Library *library, BPTR seglist, struct ExecIFace *exec) { struct Library *newlibbase; IExec = exec; library->lib_Revision = REVISION; newlibbase = IExec->OpenLibrary("newlib.library", 52); if (newlibbase) { INewlib = IExec->GetInterface(newlibbase, "main", 1, NULL); } if (INewlib) { g_seglist = seglist; return library; } else { IExec->DebugPrintF("foobar.library couldn't open newlib.library V52\n"); IExec->Alert(AT_Recovery|AG_OpenLib|AO_NewlibLib); return NULL; } } static BPTR LIB_Expunge(struct LibraryManagerInterface *Self) { BPTR result; struct Library *library = Self->Data.LibBase; if (0 == library->lib_OpenCnt) { struct Library *newlibbase = INewlib->Data.LibBase; result = g_seglist; /* Undo what the init code did */ IExec->DropInterface(INewlib); IExec->CloseLibrary(newlibbase); IExec->Remove(&library->lib_Node); IExec->DeleteLibrary(library); } else { result = 0; library->lib_Flags |= LIBF_DELEXP; } return result; }

Wasn't newlib using the Task's UserData to store some own datas ?

I don't know about OS4/newlib, but in AROS using it's shared c lib (not based on newlib) in another library can cause problems, for example when running an app from shell. Example:

- App (Dopus) is started from Shell. Apps run directly in shell task (app task == shell task).

- App loads lib (dopus.library) which loads shared c lib which connects clib context data to
app task (== shell task).

- App quits, but shared c lib is not closed, because that happens only when dopus.library is expunged (not just closed).

- clib context data stays connected to shell task, although it shouldn't, because app is gone.

- Shared clib using apps started after that from same shell may try to re-use already existing clib context, although they shouldn't (should init/create their own one).

Excellent news! Thankyou!! Been waiting so long for this!

Hopefully now I can finally compile my own AHI driver from the Emu10k source.

Quote:

The SDK is available in two versions: A "noncontrib" version that only contains the compiler and tools plus the documentation and header files for AmigaOS 4.1, and a "Lite" version that contains additional contributions.

Now this confuses me. It looked to me as if the Lite version was the full one and nonocontrib was cut down. At leat here Lite is ~86MB and noncontrib ~54MB. And noncontrib appears to be a cutdown version of Lite.

So does that mean that Lite is the first release and a bugger and more complete one is coming after? IOW will there be a Full version?

BTW I got an error when installing. Something about the SOBJS: nit being able to be copiied. But apart from that it seems fine. Except that the AHI header files are out of date. Doh!

If something crashes that has been compiled for PowerPC, the fix is not to enable 440ep optimisations, the fix is the fix the bug in the software.

How can we be sure it's a big in the software? It runs fine on my G3 without AV. I have also noticed erratic behaviour as sometimes there is no crash. But mostly things like UAE crash.

And Rogue has stated the 440ep doesn't use a full PowerPC IIRC, he said it was a BookE CPU. That was comparing the 603/G2? to a Sam CPU SoC.
