I wrote a small utility in Linux. I want to build it for Windows.
He swears at some parts of the code like this:

A small fragment of the code used:
```d

import core.sys.posix.syslog : LOG_NOTICE, LOG_ERR, LOG_INFO,
LOG_WARNING;
import core.sys.posix.syslog : syslog;
...
void log(int priority, string message)
{
syslog(priority, (message ~ "\0").ptr);
}
...
```

Yes syslog is not available on Windows as that is a Posix API. All of your calls to syslog should be guarded by a version for Posix. The Windows Event Log which is comparable, isn't 1:1 so its a bit of a task to replace it.

They are both good in their own ways, even if they are not 1:1. I can't see anything on dub-registry or in Phobos. But its not hard to implement. I.e. here are my functions for syslog and Windows Event log (I won't copy it all, it won't be helpful & the file log function is giant compared). ```d void syslog() { version (Posix) { import core.sys.posix.syslog : syslog; syslog(prioritySyslogForLevels[level], unsafeTextMessageComposite.ptr); } } void windowsEvents() { version (Windows) { import core.sys.windows.windows : ReportEventA, WORD, DWORD, EVENTLOG_INFORMATION_TYPE, EVENTLOG_WARNING_TYPE, EVENTLOG_ERROR_TYPE; static WORD[] WTypes = [ EVENTLOG_INFORMATION_TYPE, EVENTLOG_INFORMATION_TYPE, EVENTLOG_WARNING_TYPE, EVENTLOG_ERROR_TYPE, EVENTLOG_ERROR_TYPE, EVENTLOG_ERROR_TYPE ]; static DWORD[] dwEventID = [0, 0, 0, 0, 0, 0]; const(char)*[2] messages = [ ModuleLine2.ptr, cast(char*)unsafeTextMessageComposite.ptr + unsafeDateTime.length + ModuleLine.length ]; ReportEventA(windowsEventHandle, WTypes[level], 0, dwEventID[level], cast(void*)null, 2, 0, &messages[0], cast(void*)null); } } ``` Note: you also need to setup an event source on Windows i.e. ```d import core.sys.windows.windows : RegisterEventSourceA; windowsEventHandle = RegisterEventSourceA(null, cast(char*)processName.ptr); ``` and to close it: ```d import core.sys.windows.windows : DeregisterEventSource; DeregisterEventSource(windowsEventHandle); ```Here is a starting point that I myself have used in the past:I understand that programming under Windows is a shame for a programmer, but is there really no ready-made solution for using the system log in Windows?

Sounds like a simple case of not linking against the right library: https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-reporteventa Library Advapi32.lib DLL Advapi32.dll Should be as simple as adding advapi32 to your libs directive.
