Hi ragdog,

You cannot create a library from an executable. I guess you want to create an EXE exporting functions. You could use this EXE like a DLL, right?

You need to search the old forum for some examples :

I guess you're after the dynamic lib for the latest ollydbg.exe.

1) Open a Visual Studio Command Prompt
2) dumpbin /exports ollydbg.exe > ollydbg.def
3) Open ollydbg.def in a text editor
4) Delete everything except of the function names
5) Insert EXPORTS at the top
6) lib /def:ollydbg.def /OUT:ollydbg.lib

You can use the dumpbin in masm with a batch file :

Code Select Expand

@echo off
\masm32\bin\dumpbin.exe  /exports ollydbg.exe > ollydbg.def

Pause

But with :

Code Select Expand


@echo off
\masm32\bin\lib /def:ollydbg.def /OUT:ollydbg.lib

I always seem to get error:

Code Select Expand

LINK : warning LNK4068: /MACHINE not specified; defaulting to IX86
So My ollydbg.lib is 294 KB

I don't know  how you Got a lib that is only 88.2 KB ?

you can define a subsystem when you build a dll and a lib at the same time from dll.asm with no errors
Don't know how to define "/MACHINE"  with building lib from def only?

Hi hfheatherfox07,

Code Select Expand

\masm32\bin\lib /def:ollydbg.def /OUT:ollydbg.lib /machine:IX86

Hi hfheatherfox07,

Code Select Expand

\masm32\bin\lib /def:ollydbg.def /OUT:ollydbg.lib /machine:IX86

:t
Thank you That Did it ...

But Why am I still Getting a 294 KB ollydbg.lib
And the lib in the attachment is only 88.2 KB ?

Only for learning purposes ...I do not need a ollydbg.lib

Hi hfheatherfox07,

Code Select Expand

\masm32\bin\lib /def:ollydbg.def /OUT:ollydbg.lib /machine:IX86

Just for the sake Of learning .....

If I put that batch file and that def in a folder it works!

If I put This batch file and that def in a folder with : lib.exe,link.exe,mspdb50.dll

Code Select Expand

@echo off

lib.exe /def:ollydbg.def /OUT:ollydbg.lib

Pause
if exist ollydbg.exp del ollydbg.exp

It works!!!! but I get the error

Code Select Expand

LINK : warning LNK4068: /MACHINE not specified; defaulting to IX86

How ever if I add "/machine:IX86"

So the batch file :

Code Select Expand

@echo off

lib.exe /def:ollydbg.def /OUT:ollydbg.lib /machine:IX86

Pause
if exist ollydbg.exp del ollydbg.exp

I Get this Error (And It Does not work):

Code Select Expand

LINK : fatal error LNK1117: syntax error in option "mac"

Why ? that is strange ?

try placing the options before the files

a couple more thoughts....

the lib program is a stub into the linker, so....
LINK /LIB
might work

and, i remember many of the older ms command line programs accept shortened versions of switch names
so, you might try....
LIB /MA:IX86
LIB /MAC:IX86
on some of the older ones, if the switch name was long enough to remove any ambiguities, it would work

[hfheatherfox07]

Actually non of that .....

If I had that folder on my desk top it works ,
but If I put i in another folder or yet even in a another
That gives me that error

So strange..... I will leave it at that
