Hi hutch,
I have tested this one and it works fine in release mode but brakes in debug mode with this error message:

The procedure entry point BaseProcessInitPostimport could not be located in the dynamic link library

I have built it with VS Community 2013

[hutch--]

Hi habran,

This example was one of the earliest ones I found, it ran but was of little use. It took  a long series of test pieces in conjunction with a disassembler to get a reliable system that comprised of a prologue/epilogue pair and call automation that was free of stack twiddling.

[habran]

My intention was not to attack you, I just wanted to have one simple piece of code which i can use to compare with hjwasm and can be tested with debugger.
Maybe you have some other "Hello world" that can be run in debug mode?

[hutch--]

Is this any use ? This is about the simplest example I can think of. Attached file has the build batch file.

Unfortunately, I can not build it :(
I had earlier version of masm32 installed on my D disc but it did not contain include64\masm64rt.inc
so, I downloaded it again and installed. I have recently downloaded masm64 and put on the same disc, however, i've get this:
ml64test.asm(3): fatal error A1000: cannot open file : masm64rt.inc

[hutch--]

This is the file but it sounds like the rest of the system is not set up either. While I am working on the project it is a bit all over the place as some of its content is subject to change. It needs the 64 bit includes and libraries and the Microsoft binaries, ML64, LINK and RC. I am using the versions from VS2017.

Thanks hutch, 
However, there is missing to many things, I am not able to build it with files you supplied. :(
I am wondering if anyone except you succeeded to build anything.
Again, I am not trying to be rude, or to make you look stupid, I like competition and I appreciate your efforts.
Iwould like to have it running so that I can compare two assemblers output.

best regards   

[habran]

Don't worry, I have succeeded to build Win64_3 from JWasm-HJWasm samples which is included in HJWasm download :t

[hutch--]

The problem is I have posted things in bits and pieces but have not put it all together as a single package as it is still in development. The logic is install the 32 bit MASM32 SDK then add the stuff I have posted which gives you the include files, the library files, example code, code generation templates and a basic help file. You need to get the Microsoft binaries from Microsoft as I am not licenced to distribute them.

[TWell]

In my tests ml64.exe with -Zi create bad object-file for linkers from that demo.asm.
I tested versions v.10 and v.14.10.
Huge symbol table, all Windows functions?

I didn't find any debugger that can load that exe for debugging :(

[hutch--]

I have found that ArkDasm will step through an assembled EXE file but I doubt it would handle Microsoft symbols.

[BugCatcher]

x64dbg step thru it.

[TWell]

I got with version with debug info
