I want create relocation section for MenuetOS program. Currently this operation system uses flat format without segments. I want create program with one segment (code and data with zero offset) and relocation table. Is there a way to do it except writing special program which preprocess source file? May be this way appears in future ?

You can use one of the object output formats of fasm (ELF or COFF) and use some additional program to convert it into format you need. It's actually quite easy to write such program, I once made such program (called COFF2REL) for Maverick (Fabio Bizetti), but I'm afraid I have lost it and the Maverick seems to be no longer available through internet (does anybody know what happened to him?)

I wish I knew what happened to Maverick - he stopped visiting the win32asmboard, and I haven't heard from him by email either for a long time.

Anyway, converting COFF or PE to your own format isn't too difficult, even íf you're unfamiliar with the format and have to read the documentation on it, it should take max a day to code such a tool...

1.Did you use Imagehlp.dll to find main segments?
2.Can FASM compile windows program or dll with zero base address?

1. No, I was parsing the COFF (even not MS variant, classic COFF) directly.
2. Yes, it's in the manual - but I suggest you to use object format instead of PE.
