Free Pascal DOS: Is LFN required for work?

<< < (2/3) > >>

Milsa:
I think units, yes. Thank you.

I just found out that FP doesn't work on the Pocket 386. I got a SIGILL error.

marcov:
My guess would be that it is the floating point requirement.  So probably you need to install/configure the emu387.dxe from djgpp.

It used to be in the dos distribution iirc.

Milsa:
I tested FP on 86Box emulator. I set 80386DX + 80387.

This is bug report during FP IDE start:

You have to build fpc by yourself (setting -Cp80386 -Op80386). By default fpc is built for Pentium processors.

Building fpc dos version is challenging to say the least (but possible). 86Box emulates actual speed of processor so you are in for a long run.

To build fpc LFN support is required. To run fpc or fp LFN is not required.

You might check out Dos Navigator 2 that do have LFN support in it .Could be found in FreeDos packages. And you sill have to have LFN driver if you use MSDOS 6.22.
