Version 2.1 supporting LzAsm :

Switches :

QUOTE

-s : set global calling convention to STDCALL for MASM \ POASM

MessageBoxA PROTO STDCALL :DWORD,:DWORD,:DWORD,:DWORD
MessageBox equ <MessageBoxA>

-fd : output EXTERNDEFs for Fasm - direct calls

lib2inc outputs include files for direct function calls

EXTERNDEF '_MessageBoxA@16',MessageBox

-fi : output EXTERNDEFs for Fasm - indirect calls

lib2inc outputs include files for indirect function calls

EXTRNDEF '__imp__MessageBoxA@16',MessageBox

-lz : output LzAsm include files

lib2inc outputs include files for LzAsm

PROCDESC MessageBoxA :DWORD,:DWORD,:DWORD,:DWORD
MessageBox equ <MessageBoxA>

Now, since you seem to be one of the gods of the COFF/PE format, i might as well drop the bomb and ask you some questions (by all means, do not consider them as requests, i just want to know the answers from someone who knows his stuff ): 1) I'm sure you know/heard of dll2lib from binary-soft. Just for the record, that product converts a dll library to a static library, which one can then statically link to a project. My question: Is there a freeware analogous to that tool? Or any kind of alternative? I haven't found anything similar on the net... 2) Are you aware of a utility that combines multiple COFF files to a single one (COFF binder/combiner)? If not, is the COFF format subjectible to such kind of manipulation? (I mean, would it be possible for someone to actually code something such as a COFF binder?) 3) Finally, does the COFF format allow the conversion: COFF to Static Library? Would such thing be possible/feasible to be done with a tool? What are the limitations (if any) to an attempt to coding such tool? Sorry if i ask something profound, i'm nowhere near you as it comes to the COFF format / programming in general... In other words, be gentle in your reply... Again, thanks for reading this, and for sharing you tools / knowledge!

Hi Samael,

Please accept my apologies for replying late.

Thanks for your kind words.

1) I have a small project to run embedded EXEs and DLLs from memory. This method allows you to use DLLs like static libraries :

Loading and running EXEs and DLLs from memory :

2) I don't know if there is a tool to combine multiple MS COFF object modules. Studying the MS COFF object file format specification, you can modify the object modules but coding a tool to merge object files is not an easy task.

3) Using Masm's lib.exe or Pelle's Polib.exe, you can create static libraries from MS COFF object modules. It's easy :

CODE

lib /OUT:library.lib objectfile1.obj objectfile2.obj etc.

Please let me know if you have other questions.
