Re: SFML D bindings: libsfml-system.so.2.5: cannot open shared object file:
I have tested on arch linux and everything works fine, i'll try to setup a linux mint / ubuntu VM tomorrow Thanks. It seems like an issue with my system then. I've been stuck on it for a week or so, but haven't been able to find the root cause of the issue.

Re: SFML D bindings: libsfml-system.so.2.5: cannot open shared object file:
Could someone (that uses Linux) perhaps try and emulate my bug to
see if it's an issue with the bindings or on my system? That
would be greatly appreciated!
Steps:
1. Open up the terminal and type in `sudo apt-get install
libcsfml-dev`
2. Create a new D project and add the following to `dub.json`:
```
"dependencies": {
"bindbc-sfml": "~>1.0.2",
"bindbc-loader": "~>1.0.1"
},
"versions": [
"SFML_Audio",
"SFML_Graphics",
"SFML_250"
],
```
3. Add the following code to `app.d`:
```D
import std.stdio;
import bindbc.sfml;
import std.string;
import std.exception;
import bindbc.loader;
import std.conv;
void loadDyn() {
if (!loadSFML()) {
string[] messages;
foreach (const(ErrorInfo) err; errors) {
string errorStr = to!string(err.error);
string messageStr = to!string(err.message);
messages ~= format("Error: %s, Message: %s", errorStr,
messageStr);
}
throw new Exception(format("Fatal error(s) encountered whilst
calling `loadSFML()` function: %s", messages));
}
}
void main() {
loadDyn();
sfRenderWindow* renderWindow =
sfRenderWindow_create(sfVideoMode(500, 500), "Snake Smooth
Dynamics", sfWindowStyle.sfDefaultStyle, null);
sfEvent event;
while (renderWindow.sfRenderWindow_isOpen()) {
while (renderWindow.sfRenderWindow_pollEvent(&event)) {
if (event.type == sfEventType.sfEvtClosed) {
renderWindow.sfRenderWindow_close();
}
}
renderWindow.sfRenderWindow_clear(sfYellow);
renderWindow.sfRenderWindow_display();
}
}
```
It should only take around 2-3 minutes.

Re: Logging logs in Windows
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.

Are there some helpers in Phobos equivalent to std::set_difference of ugly c++
I could not find a thing doing this. And I don't want to write it
from scratch. Getting a range as output is ok too. What I need is
the following:
```c++
const std::vector v1{1, 2, 5, 5, 5, 9};
const std::vector v2{2, 5, 7};
std::vector diff;
std::set_difference(v1.begin(), v1.end(), v2.begin(),
v2.end(),
std::inserter(diff, diff.begin()));
print(v1, "∖ ");
print(v2, "= ");
print(diff, "\n");
// yielding { 1 2 5 5 5 9 } ∖ { 2 5 7 } = { 1 5 5 9 }
```

Things I've tried:
- I found someone with a similar question:
https://stackoverflow.com/questions/41516065/linux-sfml-cannot-open-shared-object-file, tried out some answers but to no avail
- I tried to `sudo apt purge` every CSFML dependency (graphics,
audo, etc) and reinstall each component (`csfml-audio`,
`csfml-graphics`) manually etc, to no avail.
- I tried to run `sudo ldconfig`... didn't work
- As a last ditch effort I tried to manually move the shared
object files to the `/usr/local/lib` directory (to try and
perhaps trick the compiler to run the program?) but to no avail.
- I tried to run on a new VM and still didn't work
- I tried to set `LD_LIBRARY_PATH` environment variable
The amount of layers I depend on make it impossible to find where
the bug is from, there are a lot of separate things going on and
it's very multilayered, I don't know where the issue is
specifically coming from as it used to work just fine I ran the
exact same commands to install CSFML previously, now when I do
it it just refuses to run.
The weird thing is when I ran a brand new virtual machine,
installed those packages, still same issue.
I am running Linux Mint 21.1, Ubuntu based. Relatively new PC.
Help would be appreciated.
