This might not be so great but it took me very long to get it assembled and linked. So this is for all of us that would like to try 64 bit programs using masm64. The next bit comes from jwasm site.
;--- Win64 "hello world" GUI application.
;--- Note: requires at least JWasm v2
;--- assemble: JWasm -win64 Win64_1.asm
;--- link: Link /subsystem:windows /entry:main Win64_1.obj
option casemap:none
includelib c:\masm64\lib\kernel32.lib ;added the c:\masm64\lib\
includelib c:\masm64\lib\user32.lib ;added the c:\masm64\lib\
externdef MessageBoxA : near
externdef ExitProcess : near
.data
text db 'Hello world!', 0
caption db 'Hello x86-64', 0
.code
main proc
sub rsp, 28h ; space for 4 arguments + 16byte aligned stack
xor r9d, r9d ; 4. argument: r9d = uType = 0
lea r8, [caption] ; 3. argument: r8 = caption
lea rdx, [text] ; 2. argument: edx = window text
xor rcx, rcx ; 1. argument: rcx = hWnd = NULL
call MessageBoxA
xor ecx, ecx ; ecx = exit code
call ExitProcess
main endp
end
Then I made a batch file to build and link it to get the program working:
;Test2.asm is the assembler file I used
;I needed to set the path to c:\masm64\bin because this is where ml64 and link is
;The "/c" ml64 switch will only asseble. No linking is done
;look at all those linker switches. I even had to specify the directory for lib
path = c:\masm64\bin
ml64 /c test2.asm
link /entry:main /subsystem:windows /machine:x64 /libpath:c:\masm64\lib test2.obj
your live will much easier when using jwasm instead of ml64.exe :U
I tried to use jwlink but could not get it to work. E3033 directive error near 'tried too many switches'. I"m just not getting anything to work maybe I am not typing them correctly. jwlink -windows or -form::=windows or .....
Link from masm64 did work with the object file jwasm created. Only because I got the switches right with link.
At this stage the amount of typing to get the file assembled and linked is pretty much the same between jwasm and masm64.
assembling an linking is trivial - I were referring to assemblers capabilities :bg

Welcome to the club, I tried to get ML64 to work for a simple project and its so badly crippled that its next to useless, I tried JWASM and as all the MASM clones it involved too many downloads of libs etc... that I decided it wasn't worth the effort. I'll stick to GoAsm, a single assembler,RC compiler and linker for x86 or x64 and a single set of header files and no import libraries at all.

GoAsm is indeed nice, but its macros are a bit limited if you need that sort of thing. I'm one of those 1 macro = 1 or less opcodes kind of guys, so it doesnt bother me.
EasyCode is also a nice IDE for it.
here it comes: the cli-version ;)

to build use following (without brackets):
-> ml64 [filename].asm /link /subsystem:console /entry:main
congratulations and welcome taz :U
However, as I've allready said, using japhets jWasm (and WinInc) makes live much easier :8)
