VLINK doubts: Can't reference "re-linked" symbols?

Hello, I have worked with Motorola 68000 instruction set for some time, developing games for the Sega MegaDrive, SegaCD and Sega 32x.


Up until time ago, I have only arranged my source codes by adding all code and files to a single tree, to assemble the cartridge's ROM image "directly" (or for each individual SegaCD files depending the case).

I'm writing a new "cross-platform" engine of sorts, compatible in Megadrive and all its addons at the same time, just needing a different makefile per different target platform.
In order to do this, I have thought in a design that links many objects into individual objects, to be linked inside other layer of objects, and so on. This would allow me to arrange different layers of objects in different order according to what goes best to target platform.


I'm beginning with the "Megadrive Alone" setup; before explaining the issue, let me show you four key files:

Makefile.MD
$(SRC)\romMd.ld (Thanks Frank Wille)
$(SRC)\screens\maingameloop.asm
$(SRC)\screens\sega\main.asm

The problem here is, I seem to be unable to do jmp GM_Sega from maingameloop.asm, unless I force it as Long address or simply disable optimizations. And Bra simply doesn't work.
It throws an error I don't know what even means:

Error 35: s1built.bin (mainloop+0xc): Calculated value 0x2080c doesn't fit into relocation type R_PC (offset=0, size=16, mask=0xffffffffffffffff).

None of this is the case from $(SRC)\init\gameinit.md.asm, where I can do bra MainGameLoop just fine.
The difference on each case is that, in the former, sega.scr.o has been repacked inside screens.md.o. While in the latter, those object files haven't.

I'd miss quite a lot of optimization if I'm forced to do Long library calls!
Is re-linking objects like this even possible? Do I have to configure different settings?
Or... is it more recommended to, instead of packing inside objects, pack filenames into lists, for inside the Makefile itself or a vlink list?

I can't build it, some files are missing, but from the link-script it looks like the two relevant sections are placed about 128K apart.

Hm, I sent the source code as PM.. but actually scratch that, here it is:
EDIT: <No more :P>

You can try by enabling/disabling the optimization flags from src\screens\maingameloop.asm.

EDIT: Well that was awkward. Didn't realize it was a branch error because it didn't appear like so at first glance. Sorry for wasking your time. And thanks, Leffmann!

EDIT: Trash, it didn't appear earlier
