Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

I was looking at the NASM code. To cooperate with your segelf support do you think that the only required changes to NASM will be in the ELF output stage?...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hi @ecm-pushbx, yes I now realise your proper username is not what I typed. I guess my lapse is a consequence of Github automatically filling it in for me most...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

@tkchia I thought I'd do a few experiments around writing the MZ EXE header differently. Before I start I want to create a simple test with ia16-elf-gcc and understand the...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hi @tkchia, Ahh, I'd seen that the value was truncated in the actual header, but I hadn't realised it was intentional. Here's the output from my little header printer script....

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hello @tkchia, > For now I guess you can try to force the output format to elf32-i386 instead of binary, by using a -Wl,--oformat=elf32-i386 option. This should yield a ELF...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hello @tkchia, Thanks for the info, I'm sure it will be most useful. I'm currently thinking of doing the calculations in the linker script just as you do now. But...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hello @tkchia, I switched back to the lma != vma method rather than -msegelf. Can you tell me which linker script is in operation when I issue this command, please?...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hello, @tkchia, Sorry to keep spamming you! I have now figured out that I am using the right linker script for a base. Thank you!

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hello @tkchia, I don't understand why the functions being linked in are different according to which output is used e.g. ##### std compile/link in one operation ~~~ .text 0x0000000000000244 0x114e...

Is there any way to avoid the linker offsetting the VMA by the size of the header in .EXE files?

Hello @tkchia, That really helped, so now the output is looking similar. Thank you!
