That won't compile because the program can't find proc32.inc. Actually, I can't find it either. Bummer.

Actually I found it in the link on the front page called "Examples". I saw nothing about being "deprecated" or "depreciated".

You need the set of fasm compatibility headers, available here: https://github.com/tgrysztar/fasmg/tree/master/packages/x86/include
See also the thread about migration from fasm to fasmg.

It does not have a Linux-dedicated section (yet), but as demonstrated by this example, the same headers can be helpful.

Yes, that's the page I linked. The page itself states that "Nowadays new examples are contributed on the relevant forum."

Yes, I already downloaded FASMg-master. Shouldn't something that critical be included in the FASMg package?

New problem: it won't link.

What is the format?

By itself fasmg is an universal engine that can be extended into many different frameworks and architectures. The "fasm 1 compatibility" is just one of them.

New problem: it won't link.

I thought you had the project working with fasm 1 already and then asked about migrating it to fasmg. Why didn't you start with fasm 1, for which the example was actually intended?

The very first line of the original source tells you that. It is ELF object format.

If everyone wanting to learn FASMg must first become a FASM 1 expert, put that in the documentation so everyone can know from the start the prerequisites. The advertisement for FASMg implies that it is a mature standalone product not requiring FASM 1 experience.

See what I mean? If that is what you want then put that in the documentation on page one. As for me, I don't want to learn FASM 1, I want to learn FASMg. Is that not possible? If I were a beginning programmer, I would have already given up.

As already mentioned, fasmg can be used as a base for different assemblers, not necessarily x86, and even for x86 it could implement syntaxes different than fasm 1. But if you choose to use "fasm compatibility package" then it's emulating the syntax of fasm 1, obviously.

You have taken an example written for fasm 1, from the page that mentions that explicitly.

Normally you would have even less luck trying to take an example for one language and feeding it to compiler of another one (and fasmg by itself is just a bare "data assembly language", not even an x86 assembler), but here it was possible, because fasmg can be extended with specialized headers to become an assembler for an architecture and syntax variant of choice. So with "fasm compatibility package" it becomes possible to assemble sources written in fasm 1 syntax. This is what I provided.

You mean the page with nothing but depreciated examples that say nothing about fasmg.

This section contains programs created with the flat assembler and contributed by users as sample material for others to learn from. Most of them were submitted in the early days of this website, and they all have been designed for flat assembler 1.

Nowadays new examples are contributed on the relevant forum. You may find some tutorials there as well.

Examples for flat assembler g are gathered in a dedicated thread on the message board.

If in order for fasmg to be able to assemble object files for Linux I must install fasm1 first, then I don't need fasmg to do that.

SUGGESTION: Since fasmg is allegedly a successor to fasm1, take all the macros, incs, and docs for fasm1 and put them into the fasmg package because that is what fasm1 is: fasmg plus all the macs and incs.

It is an assembly engine designed as a successor of the one used in flat assembler 1, one of the recognized assemblers for x86 processors.

Let me quote the page itself:

You told me the examples page was for depreciated code, so I believed you. So get rid of the apparently useless examples page because it contains misleading information.

Not only does it say that the examples there are for fasm 1, it also points where to look for fasmg-related material instead.

That's not what was implied. The thing is, if you first tried to compile the example with fasm 1, which the example was intended for, you would run into exactly the same problem at the linking stage. It unnecessarily complicated the discussion, because this problem was completely unrelated to the concern of migrating from fasm 1 to fasmg, which the topic at least initially seemed to be.

The exact description from the documentation is:

Quote:

So fasmg is a successor of fasm's engine, not of fasm as a whole. Even fasm 1 could be bent to become almost a different language with a right set of macros, and it was done several times by the members of this board. With fasmg I pushed it one step further and provided just a bare engine, to be used as foundation for such projects.

If fasmg was fasm 2, I would publish it as such, and it would then likely replace fasm 1 on the pages. But it is not fasm 2 and fasm 1 is already good enough at what it is.
