DEVPAC 68881 required error

[exxos]

So my first try to compile my own GB6 ASM code isn't going well..

In the code it has..

OPT P=68040,P=68881
OPT O+

Fair enough..

But trying to compile I get a error...

Do I need a FPU lib or something for it to compile ?

Not that I have much experience with Devpac, but the syntax of the OPT P line should be different according to the manual:

Thanks, tried it, but still get the same error message :(

What is the statement in line 423, then?

EDIT: Also I wonder if the combination of 68040/68881 is even allowed in Devpac, considering that the 68040 has a builtin FPU.

Its the ASM routines for GB6.. d.m.l wrote them, and of course it compiled.. So I don't think the source is wrong, unless he used some other compiler. Will have to see if I can find his email address and ask him about it.

Could it be that to compile the code, you need to have an FPU of the correct type installed in the computer?

I tried compiling in Hatari , as a 030 with FPU already.. I thought maybe steem was being moody, but have same issue on Hatari.

[czietz]

OK, so the assembler needs a FPU on the development machine to handle floating point constants. WTF! They could have easily done that entirely in software. I know why I don't like Devpac much.

The particular line...
FMOVE.S #1.001,FP0
... compiles fine under Hatari with 68030 + FPU, if I use the 68030 version of the Devpac assembler, i.e., GEN030.TTP. I guess the regular 68000 version does not recognize the FPU if interfaced to a 68030.

[exxos]

ah so there is a 030.ttp in there, but just swapping the files gives another problem..

So back to Hatari then... see what happens...


EDIT:

Ah here we go then...

So this file should match the GB6 asm file... lets see...

[exxos]

So the only file it compiles to anything similar is "Lattice Linkable".. But the end of the file is different :shrug:
