I'm trying to kind of write my own x64 Hello world program in FASM on Windows
I tried to rewrite this version: How to write to the console in fasm?, to a x64 program like this:
format PE64
entry start
include 'win64a.inc'
section '.code' code readable executable
start:
push hello
call [printf]
pop rcx
push 0
call [ExitProcess]
section '.rdata' data readable
hello db 'Hello world!', 10, 0
section '.idata' import data readable writeable
library kernel,'KERNEL32.DLL', \
msvcrt,'msvcrt.dll'
import kernel, ExitProcess,'ExitProcess'
import msvcrt, printf, 'printf'
Now the problem is that this compiles fine, but when it is executed it doesn't print anything to the console.
Why does this not work, is printf of msvcrt silently incompatible with x64?
Have I overseen something?
Can someone tell me how to rewrite this for it to actually print "Hello world!"?

This Python code shows how to call some process in Windows 10 and to send to it string commands, to read its string responses through stdin, stdout pipes of the process:
Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:37:50) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from subprocess import *
>>> p = Popen("c:/python38/python.exe", stdin=PIPE, stdout=PIPE)
>>> p.stdin.write(b"print(1+9)\n")
11
>>> p.communicate()
(b'10\r\n', None)
>>>
As you can see the python.exe process returned 10 as an answer to print(1+9). Now I want to do the same in Pharo (or Squeak): in Windows 10 OS - I suppose something similar, i.e. short, simple, understandable, really working.
I installed OSProcess, ProcessWrapper (they were missing in Pharo, also its strange that I got warning that they are not marked for Pharo 8.0 and were not checked to work in Pharo 8.0, but OK), and I tried ProcessWrapper, PipeableOSProcess (copy-pasted different snippets from the Web), etc - with zero success! The results were:
nothing happens, python.exe was not started
VM errors console was opened (white console in the bottom of the Pharo, which is controlled with F2 menu)
different exceptions
etc
Would somebody show me simple working example how to start a process and to to send it commands, read answers, then send again, and so on in some loop - I plan to have such communication in a detached thread and to use it as some service, because Pharo, Smalltalk in general is missing most bindings, so then I will use subprocess communication like in "good" old days...
I know how to call a command and to get its output:
out := LibC resultOfCommand: 'dir ', aDir.
but I am talking about another scenario: a communication with a running process interactively (for example, with SSH or similar like in the example above - python.exe).
PS. Maybe it's possible to do it with LibC #pipe:mode even?
Let me start with that the PipeableOsProcess is probably broken on Windows. I have tried it and it just opened a command line and nothing else (it does not freeze my Pharo 8). The whole OSProcess does not work correctly in my eyes.
So I took a shot at LibC which is supposed to not work with Windows.
I’m a module defining access to standard LibC. I’m available under Linux and OSX, but not under Windows for obvious reasons :)
Next is to say that Python's Windows support is probably much better than Pharo's.
The solution, which is more like a workaround using files, is to use LibC and #runCommand: (I tried to come up with a similar example as you had shown above):
| count command result outputFile errorFile |
count := 9+1. "The counting"
command := 'echo ', count asString. "command run at the command line"
outputFile := 'output'. "a file into which the output is redirected"
errorFile := 'error'. "a file where the error output is redirected "
result := LibC runCommand: command, "run the command "
' >', outputFile, "redirect the output to output file"
' 2>', errorFile.
"reading back the value from output file"
outputFile asFileReference contents lines.
"reading back the value from the error file - which is empty in this case"
errorFile asFileReference contents lines.
I was trying to compile the following "hello world" source file after some time away from Idris using a nix-shell environment (direction):
module Main
import Effects
import Effect.StdIO
hello : Eff () [STDIO]
hello = putStrLn "Hello world!"
main : IO ()
main = run hello
My output was as follows during the experimentation; despite specifying what seems to be the right library, I still get the same error at the end:

Try to add -p effects to your commandline as in
idris -p effects --codegen javascript hello.idr -o hello.js
this will load the additional library/package. You can avoid doing this by defining an ipkg file, which describes your build. See here: http://docs.idris-lang.org/en/latest/reference/packages.html

In Perl 5 I would have used print "#INC"; to see what paths are searched for the lib before the error is thrown. Using say flat $*REPO.repo-chain.map(*.loaded); either is before it loads or after it throws the exception.
Any help would be much appreciated - or maybe a hint on what to put in ~/.perl6 as I can't get a symlink to work either.
The error message itself is telling you what the library paths available are. You are failing to print them because you are expecting a run time action ( say ) to take place before a compile time error -- you could print out $*REPO at compile time, but again the exception is already showing you what you wanted.
$ PERL6LIB="/GitHub/perl6-Units/lib" perl6 -e 'BEGIN say $*REPO.repo-chain; use Foo;'

You can see /GitHub/perl6-Units/lib is showing up in the available paths, which is unlike your example. I'd question if your shell/env is actually setup correctly.
I am posting here after asking the question at the openslice dds forum, and not receiving any reply.I am trying to use opensplice dds on a ubuntu machine. I am not sure if it serves as a proof of proper installation, but I have pasted my release.com file below. Now, I was able to run the ping pong example just fine. But when I ran the executable sac_helloworld_pub ( HelloWorld example in the C programming language), I got the following error

I did some searching, and it looks like I need to be running the ospl start command from the terminal. But when I do so, I get a No command ospl found message. Below is the release.comfile's contents

Sorry for the holidays-driven lack of 'reactivity' on the OpenSplice forum .. I've answered your question there though ..
Here's that same answer for completeness:
*For the 6.3 community-edition, the deployment-model changed from shared-memory (v5.x) to the so-called single-process standalone deployment mode where the middleware is simply linked (as libraries) with the application so you don't need to start any daemons first (as was the case for the federated 'shared-memory' mode that was the default in V5).
So its OK that you get the error when trying to call 'ospl' as thats not used anymore so isn't in the distribution.
Now to your issue, your release.com looks OK to me, but perhaps you didn't actually 'source' it in your environment i.e. calling it with a '.' in front of it:
promtp> . release.com
you can verify that by doing an 'echo $OSPL_HOME' in your shell and see if it actually shows the value of the env. variable as set by the release.com.
Hope that helps,
-Hans*
Basically what the title says: what's the process for compiling your average go* file? drop it on a compiler and execute the result?
*note: The OP edited the question replacing "go" with "C", before it was rolled back. So some of the answers won't make sense.
Did you take a look at the Go tutorial at http://golang.org/doc/go_tutorial.html
Here's how to compile and run our program. With 6g, say,
$ 6g helloworld.go # compile; object goes into helloworld.6
$ 6l helloworld.6 # link; output goes into 6.out
$ 6.out
Hello, world; or Καλημέρα κόσμε; or こんにちは 世界
$
With gccgo it looks a little more traditional.
$ gccgo helloworld.go
$ a.out
Hello, world; or Καλημέρα κόσμε; or こんにちは 世界
