Using NASM as a C library (Windows .lib or .dll)
« on: July 26, 2011, 11:54:01 AM »
Can NASM be used (or compiled) for use as a Windows .lib or .dll library?  I would like to be able to call it's assembler functionality programmatically, e.g. someFunctionNameLike_NasmAssemble("pop eax") and have it return the x86 binary op codes.

Thanks for the help!

Not without hacking it.  You may want to look at Yasm although I'm not sure if it's interface is what you're after.

Thanks for the advice.  I am looking through Yasm (libyasm) to see if I can find the interface I want.  It doesn't appear to be able to assemble programmatically, but it has quite a few options (plus it is created to be used as a library).

If I cannot get it to work, I'll try to hack at the NASM source and try to convert it to a library.

If I do find a good library for this, I will post to the forum.  Thanks again!

suctiondart,

Microsoft has an inline assembler.  I tried it.  It caused my PC to hang whenever the VB6 environment elected to scan the source code while I was editing.

I'll be taking a look at Yasm, too.  Thanks, Rob, for that tip.
