[modern compass]

What are you trying to do with that dll?

[mortal raft]

[lament eagle]

(Or not related to mod?)

[mortal raft]

@mortal raft has reached level 1. GG!

[mortal raft]

its more a client

I made the modules etc but the src is for a old version and I tried to update the offsets etc but I need to try inject to see wich errors but Idk how to compile it has dll

[lament eagle]

There is exising DLL, and you are trying to replace it with custom one?
What are you using to build sources?

[mortal raft]

so uh I took an old source from a known client and I remade it better adding modules deleting some etc I updated some offsets etc to update the source to a newer version but there no existing dll yet I wanna create one from the source I remade and for code I get help from a friend and I use visual studio

[lament eagle]

If your solution is consist of multiple projects, just setting the target of desired project to DLL is fine I guess.

If not, you have to split existing project into multiple ones in order to build DLLs AND executables

[mortal raft]

well I just want to do a dll with this src yes

[lament eagle]

if you already have an solution and projects, just press build and it should create something.
If application(.exe) is produced, you have to change the output type

[mortal raft]

well im trying but look it keep telling me this when I build dll

oh its in french mb

[lament eagle]

Do you have any means to share the sources (like GitHub)? Since it's hard to tell what is the actual error without looking into the sources themselves.
You can just drop the zip file at worst.

Anyway, it seems that the source cannot find "stdext" identifier, followed by double colon

If you are using <hash_map> or <hash_set>, consider using <unordered_map> or <unordered_set>
not related, i think

stdext::make_checked_array_iterator is the Microsoft's extension, which is defined in <iterator> header. Do you include one?

[mortal raft]

yes sure I send u in dms if u dont mind

[mortal raft]

Thanks to @lament eagle its fixed and its done !
