using JWasm with mingw headers and libs (?)

[jcfuller]

Also note I am using the 32bit MinGW TDM4.6.1 not TDM64 for these tests as it's easier to use ld and I have no interest in 64bit assembler.

I do use MinGWTDM64 for all my Bcx/Ubx/C++ work.

jcfuller,

I thought you said "elf vs coff". You meant "omf vs coff"? Indeed omf is more compatible with mingw tools-chain, nevertheless it supports coff too.

[jcfuller]

drizz,
omf  ??
As I said I'm a novice but ....
In my original bat file post I use -elf for jwasm and --format elf32-i386 for ld.

Then I tried -coff for jwasm and --format pe-i386 for ld.

Is --format pe-i386 for omf ?
If so what is coff. The information for ld is a bit confusing to me.

Thanks

James

Ignore my last post :bdg
There are so many variations on a theme that is easy to get confused.

I don't know what input format is better for ld or if there are any issues with linking elf objects to PE.
I use -elf for linux 32, -elf64 for linux 64, -coff for win32, -win64 for win64

[jcfuller]

This is confusing and tracking down the information is just as bad!

As this is stll about the TOPIC I'll add more....

This is what I understand so far along with info on what has confused me.

MinGW gcc/g++ 32bit default is coff.
jwasm default is omf
ld appears to be able to handle a mixed bag of formats
I'm not sure on MinGW ar?

I compiled a few asm routines with jwasm xxx.asm; I assume  omf  xxx.obj files
I then used ar to create a static library ar rcs *.obj libmylib.a
Next I compiled asm code with jwasm using -elf and linking with ld using MinGW Windows libraries and -lmylib
All worked fine.

I wrote a simple demo on linux and japheth added this header which started the confusion on my part.

;very simple jwasm gtk example (written by jcfuller)
; create a Linux binary
; 1. assemble:       jwasm -elf -zcw -Fo=gtk01.o gtk01.asm
; 2. link with LD:   ld -s -o gtk01 gtk01.o -I/lib/ld-linux.so.2 `pkg-config --libs gtk+-2.0`
;
; create a Win32 binary with MinGW
; ( MinGW installed at C:\MinGW, GTK+ installed at C:\GTK )
; 1. assemble:       jwasm -elf gtk01.asm
; 2. link with LD:   ld -s -o gtk01.exe gtk01.obj -Lc:/gtk/lib
;                    -lgtk-win32-2.0.dll -lgobject-2.0.dll -Lc:/mingw/lib -lmsvcrt

Time to go code some PowerBASIC and get my head straight :)

If it works why bother?  :)

OT:
James, do you perhaps have a complete set of include files for jwasm on linux? XWindows, some kind of LinInc system or anything else like that? I would be interested in that.

[jcfuller]

drizz,
  From what I remember it's a bit of this and a bit of that. I think I have a pretty complete gtk-2.
Some protos for c libraries stdio, stdlib ..... but not complete.
I ported Raymond's fpu library to linux 32bit. I really should get these a bit more organized.
