what is your c++ version?

i think
Saro
What compiler do you use?
Saro
i am using visual studio how i check it

now i have found it thank you

Actually, you can do the same thing on C++14 just using system command from stdlib.h

Can someone explain why this testcase fails?
I might have the wrong understanding of unordered_multiset

I think the problem here is set_intersection requires sorted ranges
dearfl
if u change unorder_multiset to multiset, it works fine

Hi guys, I have to write a client/server code that works as a "bulletin board" for every client to read. I was thinking that, maybe, I could see every entry in the board like a node, and therefore the board is just a sequence of nodes, therefore a list. The problem is, if this board grows too large, is this solution too heavy to implement? Do I have other data structures that could somehow accomplish in a better way the task?
𝕷𝖔𝖗𝖊𝖓𝖟𝖔
I was thinking about trees, but the problem is that they are very hard to implement, and I am working with different types of data in each node, so it would be hard to do the research, and the project does not ask to find a certain node among others, so I don't see the advantage in using trees here

who knows about win32 api?
Alireza
my question is so basic I google it but i didn't get the point!! what is handel?
pavel
Nothing special, something like "pointer " or unique id using to control "handle" something
Saro

There are events and you are setting a handler for that event. When there is an event it will call the function which you have set as the handler.

how can i get a windows binary from a unix makefile?
Don
cygwin etc not helping i need the windows binary
r
I would try mingw32-make, but the ideal would be to have something windows-specific

cant use mingw32 because of x64 system and i cant install all the packages i need on msys
Saro

Has that makefile some constant parameters?
Saro
CC, CFLAGS, CXX, CXXFLAGS
Saro
Something like these
r
cant use mingw32 because of x64 system and i cant install all the packages i need on msys
it's not about building for 32 bits, it's about recognizing the makefile
r
but again, it's better to have something to build in somewhere like the developer powershell/prompt for VS

idek no more tried it on probably 20 shells by now
Saro
cc cdefines etc yea
I think you can change the parameters for your compilator and it seems will work.

luajit, iirc, uses the mingw32-make to regognize the unix makefile, but i'm not sure (something like this actually shouldn't be done at all :x )

but for me it throws errors because its not x32 and i cant use cygwin beacause thats unix

20$ for anyone who gets me to compile the windows binary of this

Again, mingw32 does not refer necessarily to building something for i686

yes but running make in the project folder errored saying code model large is not supported in the 32 bit mode

what is the meaning of
HMODULE Hmodule =NULL
for example when I see this code:
int x=4;
I understand that x is a variable which its type is integer and it can store number value like 1,2,......
but what about this?:
HMODULE Hmodule =NULL
pavel
HMODULE is pointer
pavel
Who knows, it's not a standard type. Looks like win api style
Alireza
so can u explain this line:HMODULE Hmodule =NULL
pavel
HMODULE is typedef of typedef of typedef of.... Handler
pavel
so can u explain this line:HMODULE Hmodule =NULL
Here he initialize it by null , mean we mark it as - we don't what to handle yet, next we will initialize it by real address
Alireza
Here he initialize it by null , mean we mark it as - we don't what to handle yet, next we will initialize it by real address
so hModule is a pointer who point to nowhere
Alireza
do u know what is the difference between a pointer with * and this kind of pointer?
r
It seens like you do not know what your setup is using, i would recommend understanding it first
Don
I don’t know. May be mingw?
ive used mingw but makefile says cc=g++ so that should be the compiler right?
Don
It seens like you do not know what your setup is using, i would recommend understanding it first
i know, where to start then
Don
can i maybe compile without makefile
r
Displaying envvars is a start
Don
i just want some small changes in the source code and this makefile stuff is costing me a week
r
can i maybe compile without makefile
Surely, check the msvcbuild script, from the example i've already mentioned, luajit
