this picture is from another editor (vscode)

btw the platform is windows

[karmic viper]

What build system, cmake?

[hexed isle]

Dunno im new to cpp

But im trying to use protobufs

What i do normally is just use compile_commands.json

Been stuck for hours

i got clang++ and g++ tho

should i give compile commands content ?

[karmic viper]

Yeah

Did you write it by hand?

[hexed isle]

yeah

[

i tried even using gpt

still didnt work

[karmic viper]

So where do you have this file?

[hexed isle]

same directory

well one thing i noticed

dont have
-IC:/protoc-28.0-rc-2-win64/include -LC:/protoc-28.0-rc-2-win64/lib
.cc .h files

hold up i think im cooking

[hexed isle]

im cooked

yo i found the pkgs but idk how to include them

@karmic viper

[karmic viper]

Wait, does this program compile for you at all? When you compile it in the terminal

And if so, what compiler command do you use?

[hexed isle]

@karmic viper

imma try install cmake and run it over cmake list in the folder i have

[karmic viper]

Make it compile in the terminal first, and then start fixing the red squiggles

[hexed isle]

i fixed it by just running cmake and doing extra stuff ..... but at what cost

somehow my paths got wiped 💀💀💀💀

[karmic viper]

Paths?

[karmic viper]

Yeah this doens't look good

[hexed isle]

damn shit still cooked asf

doesnt compile

wtf

displaying errors for 5 mins

[hexed isle]

mr dippy @karmic viper

well basically idk if u all ever used protobuf

but in cpp what seems to u gotta compiler the whole project which will give you something called protoc and includes files

thats what i concluded

[hard quiver]

i have not

[hexed isle]

and then link the includes to ur project

[hexed isle]

google worship it

same for games

well for now i tried compiling the protobuf with cmake

they said i should do it in readme

i get this

which seems to be just absl libraray missing

[hallow imp]

I've managed to link to protobuf without any issue.

[hexed isle]

windows ?

[hallow imp]

without zlib, without absl provider

[hallow imp]

linux.

so my question

what are you trying to do precisely

[hexed isle]

says.... it all

[hexed isle]

some private server for a game

they use protobuf

i need protobuf to be able to marshal and unmarshal msgs

[hard quiver]

im doing it on windows rn

wait a sec :)

my cpu burning rn

[hexed isle]

btw

when i do cmake

[hallow imp]

yeah it doesn do anything for me. I mean what are you doing in your project regarding protobuf.

[hexed isle]

some random errors popup 🤣

[hexed isle]

tcp connection

tcp server

well

i didnt even bulid 5% of full thing yet lol

btw im beginner, i used to use go and python but i got nice knowledge of low level

this the current code if u want to see

[hard quiver]

you can use winget

[hexed isle]

i did check it

actually nvm

i didnt try check if i will get includes error aswell

[hard quiver]

CPMAddPackage("gh:protocolbuffers/[email protected]")
target_link_libraries(${PROJECT_NAME} PRIVATE protobuf::libprotobuf)

it took 2 lines for me to link 🤔

ill see if i can include the file ur missing

[hallow imp]

took a bit more with FetchContent

include(FetchContent)

FetchContent_Declare(
    protobuf
    GIT_REPOSITORY https://github.com/protocolbuffers/protobuf.git
    GIT_TAG        v33.0
    # Faster fetch; comment these two lines if you need full history/submodules
    GIT_SHALLOW    TRUE
    SOURCE_SUBDIR  cmake
)

set(protobuf_BUILD_TESTS OFF CACHE BOOL "" FORCE)
set(protobuf_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)
set(protobuf_WITH_ZLIB OFF CACHE BOOL "" FORCE)
set(protobuf_ABSL_PROVIDER OFF CACHE STRING "" FORCE)
set(BUILD_SHARED_LIBS OFF CACHE BOOL "" FORCE)

if(PROTOBUF_ABSL_PROVIDER STREQUAL "package")
    find_package(absl QUIET)
endif()

FetchContent_MakeAvailable(protobuf)

set(Protobuf_FOUND TRUE)

[hexed isle]

You can install the protocol compiler, protoc, with a package manager under Linux, macOS, or Windows using the following commands.

this will just get compiler i assume

[hard quiver]

hmm could be

[hexed isle]

i mean u can just download the compiler by itself

but they say cpp must build it

so u get the includes aswell

so what should i do

someone told me , just use rust/zig

🤣

[hard quiver]

include(cmake/CPM.cmake)

find_package(Catch2 3)
set(protobuf_BUILD_TESTS OFF CACHE BOOL "" FORCE)
set(protobuf_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)
set(protobuf_WITH_ZLIB OFF CACHE BOOL "" FORCE)
set(protobuf_ABSL_PROVIDER OFF CACHE STRING "" FORCE)
set(BUILD_SHARED_LIBS OFF CACHE BOOL "" FORCE)
set(CMAKE_POSITION_INDEPENDENT_CODE ON)

CPMAddPackage("gh:protocolbuffers/[email protected]")
target_link_libraries(${PROJECT_NAME} PRIVATE protobuf::libprotobuf)

use CPM

works for me

[hexed isle]

what is cpm?

sorry for being noob

[hard quiver]

its a wrapper around cmake fetchcontent

basically a way to do one liner build from source stuff

[hexed isle]

dang

[hard quiver]

its not a good option for big team projects but for "just make it work" solutions, its good

basically i tell it to download and build the source from github

[hexed isle]

meh im not elon mask

space x

well any links ?

[karmic viper]

You said you fixed it, of course I dipped

So did Laci's suggestion work?

[hexed isle]

i didnt

[hexed isle]

i will try now after i try something i tried asking gpt about

[hexed isle]

yeah seems like only was fixed at editor

[karmic viper]

Ah I see

[hexed isle]

i dont use gpt, vibecoding sucks

just when im hopeless

[hexed isle]

ah.... how to use and install cpm

[hard quiver]

download CPM.cmake from github

and include it in cmake

[hexed isle]

cmake folder of protobuf ?

[hard quiver]

no

just make a cmake directory in your project

and put CPM.cmake there

and include(cmake/CPM.cmake)

its just a cmake script that does stuff for you

[hexed isle]

laugh at me

🤣

[hard quiver]

include it in cmake...

not in your cpp source files

wait are you not using cmake

[hexed isle]

im not, idk im always editing the json file

[hard quiver]

use cmake 👍

[hexed isle]

found someone doing this on google

[hard quiver]

is that zed

or what editor is that

xd

[hexed isle]

ye

vscode is bloaty

[hard quiver]

use a real ide

[hard quiver]

clion mybeloved

[hexed isle]

wym clion

i mean i got vscode

i used it before zed

[hard quiver]

its an IDE

with good cmake integration

[hexed isle]

never heard of it

[hard quiver]

i use it for all c++ stuff

[hard quiver]

its from jetbrains

its free

👍

heavyweight, but good

[hexed isle]

intresting, would it spoonfed me

fixing problems like rn /

[hexed isle]

btw gpt telling me to disable test units

that seems very promising....

[hexed isle]

bro im gonna cry

still trying fix the problem like see this

g++ ps.cpp agar_v26.pb.cc -o ps.exe -std=c++20 -IC:/Users/spn/Desktop/install/include -IC:/Users/spn/Desktop/absl-install/include -LC:/Users/spn/Desktop/install/lib -LC:/Users/spn/Desktop/absl-install/lib -lprotobuf -labsl_synchronization -labsl_base -labsl_raw_logging_internal -labsl_malloc_internal -labsl_spinlock_wait -lws2_32 -lstdc++ -static

[karmic viper]

This command is from the cmake log, right?

I recommend dropping all those custom -I and -L flags and installing those libraries in MSYS2

[hexed isle]

no

my eyes shutting

working since 4 am

12 hours straight

no avail

at this poin

t

im gonna try pay someone to do it no jokes

actually

should i just try link it on unix based system

[karmic viper]

From where then?

[hexed isle]

terminal

[karmic viper]

But like, weren't you using cmake before?

[hexed isle]

gonna give up on windows... was going to give up on cpp just bcuz of that

[karmic viper]

Or was that only for protobuf?

[hexed isle]

only for compiling protobuf

[karmic viper]

You don't need to give up on anything, just install all those libraries in MSYS2. This is the exact same thing you would do on linux

[hexed isle]

i did

[karmic viper]

Type pacman -Qe in MSYS2 and send the output

And also type gcm g++ in whatever terminal you're compiling from (not msys2 I assume?)

[karmic viper]

Do you want to use g++ or clang++ ? I saw you use clang before, but now you're using gcc

[hexed isle]

i got both lol

should i get rid of one of them

i assume clang

[karmic viper]

No, keeping both is fine

[hexed isle]

hmmm

[karmic viper]

Does your program need abseil?

[hexed isle]

yeah

[karmic viper]

pacman -S mingw-w64-x86_64-abseil-cpp

[hexed isle]

i did on my desktop and cmake it but lets see on msys2

ok installed

what now

[karmic viper]

I'm not sure if you did it right, and it's faster to install in msys2 than to check

Now just g++ ps.cpp agar_v26.pb.cc -o ps.exe -std=c++20 -lprotobuf -labsl_synchronization -labsl_base -labsl_raw_logging_internal -labsl_malloc_internal -labsl_spinlock_wait -lws2_32

This is your command, but I removed all -I, -L, and -static too for now

If this doesn't work, send the first ~10 errors

So?

[hexed isle]

sorry

i had to dip

[hexed isle]

in msys terminal ?

labsl_malloc_internal -labsl_spinlock_wait -lws2_32

lemme try edit so it uses the protobuf i compiled in desktop

g++ ps.cpp agar_v26.pb.cc -o ps.exe -std=c++20 -lC:\Users\spn\Desktop\install\include -labsl_synchronization -labsl_base -labsl_raw_logging_internal -labsl_malloc_internal -labsl_spinlock_wait -lws2_32

still cooked

but its Protobuf C++ gencode is built with an incompatible version of

btw im not running in msys

[karmic viper]

Doesn't matter, because gcm g++ showed you're running the same msys2 GCC even outside of the msys2 terminal

[karmic viper]

Ok, so regenerate the headers using the protobuf you installed in msys2

[hexed isle]

..

[hexed isle]

Yeah

[hexed isle]

Where to find the protobuf installed in msys if u mind me asking

[karmic viper]

Uhh, you mean protoc?

I never used it, is this you generate the headers?

You should be able to directly run it from your terminal. It's at C:\msys64\bin\protoc.exe, but this is the same location where you have g++.exe, and since you can run that directly, you should be able to run protoc directly too

[hexed isle]

Well

From where tf its pulling the includes of protobuf when i do -lprotobuf

nuh uh

[karmic viper]

Ah sorry, C:\msys64\mingw64\bin\protoc.exe

[karmic viper]

It searches C:\msys64\mingw64\include by default

You can confirm this by adding -H, it'll dump all headers it includes

[hexed isle]

yep exists

[karmic viper]

Good. But does just protoc alone not work?

[hexed isle]

protoc compiles .proto to .cc, .h files

but they need the includes

[karmic viper]

Ok, but what does this have to do with my question

[hexed isle]

@karmic viper i got rid of this version error

[karmic viper]

Good

[hexed isle]

means

no

but im back at the many errors

[karmic viper]

Can you run gcm protoc? I'm curious

[karmic viper]

You mean after you fixed the version error?

Can you show the first ~10 errors again?

[hexed isle]

ye

[hexed isle]

sure

[karmic viper]

Ok, let's try pacman -S mingw-w64-x86_64-lld, and then build with clang++ -fuse-ld=lld instead of g++

[karmic viper]

[hexed isle]

alr

[karmic viper]

Then both protoc and C:\msys64\mingw64\bin\protoc.exe should do the same thing. But I guess this doesn't really matter

[hexed isle]

fr thats weird

what i do with clang++ -fuse-ld=lld?

[karmic viper]

Same command as you used before, but replace g++ with clang++ -fuse-ld=lld

[hexed isle]

alright

[karmic viper]

Clang with LLD isn't sensitive to the order of the -l flags, unlike GCC. If this works, this'll mean that the order is wrong

[hexed isle]

less error msgs , i got only those

well

its absl again

[karmic viper]

Okay, let's get rid of -lprotobuf -labsl_synchronization -labsl_base -labsl_raw_logging_internal -labsl_malloc_internal -labsl_spinlock_wait -lws2_32 and get all the flags from pkg-config

Install pacman -S mingw-w64-x86_64-pkgconf

[hexed isle]

i feel we are cooking

[karmic viper]

🙂

Try running pkg-config --libs --cflags absl_log, what does it print?

spn@DESKTOP-VEKLTVB MINGW64 ~

should this command work outside msys

maybe i should try compile inside msys ?

[karmic viper]

Everything that you install via pacman -S mingw-w64-x86_64-... gets installed to C:\msys64\mingw64. And since you apparently have C:\msys64\mingw64\bin in the PATH, no surprise that it works

[karmic viper]

It shouldn't change anything

[karmic viper]

Ok, so try those

[hexed isle]

ye ik but sometimes random things happens

[karmic viper]

When they do, it's usually a skill issue 😛

[hexed isle]

copy all and put it in the command ?

[karmic viper]

Yes

[hexed isle]

lmao

[karmic viper]

In general, you should try to get all your library-specific flags from pkg-config instead of trying to guess them yourself

[karmic viper]

Ok, apparently protobuf works with pkg-config file too. So you can drop -lprotobuf and do pkg-config --libs --cflags absl_log protobuf

[karmic viper]

So does this work?

[hexed isle]

lmao absl still missing

[hexed isle]

include all of em

[karmic viper]

pkg-config --libs --cflags absl_log protobuf absl_check

This maybe?

FYI instead of copypasting the flags you can do clang++ -fuse-ld=lld ps.cpp agar_v26.pb.cc -o ps.exe -std=c++20 $(pkg-config --libs --cflags absl_log protobuf absl_check)

[hexed isle]

hold up

oo

[karmic viper]

What does gcm clang++ print?

It should be C:\msys64\mingw64\bin\clang++.exe, but it's probably not

[karmic viper]

Hah interesting

Try replacing clang++ -fuse-ld=lld back with g++

[hexed isle]

yeah just asked gpt

[karmic viper]

I gotta go, will reply later 🙂

[hexed isle]

i hope it works

ye wtf

gpt says just rebulid whole shit with g++ again

[karmic viper]

This is super weird

Probably just missing something from pkg-config

[karmic viper]

Can you paste this as text so I can google the error?

[hexed isle]

lmao nothing on google @karmic viper

[karmic viper]

Try with -DGOOGLE_PROTOBUF_NO_THREADLOCAL

[hexed isle]

okay

btw i didnt include those

[karmic viper]

Didn't include them from where?

From pkg-config output?

[hexed isle]

ye

[karmic viper]

If so, try adding them first, and ignore -DGOOGLE_PROTOBUF_NO_THREADLOCAL for now

[karmic viper]

But why?

[hexed isle]

idk i thought only those with -l

[karmic viper]

All of them

[hexed isle]

it compiled 💀💀💀💀

[hexed isle]

when i added those

lemme try run

[karmic viper]

🔥

[hexed isle]

lemme try connect

and send packet

[hexed isle]

fr at day 4

[karmic viper]

Btw, you tried static linking before. To do that, both add --static to pkg-config (it'll probably print even more flags), and also pass -static to the compiler

[hexed isle]

shall i try rn ?

tho

[karmic viper]

[hexed isle]

if i do -static

it wont need dependencies in another machine right

[karmic viper]

Yeah. Or you can just copy dlls next to your executable, and zip them together

[hexed isle]

nah static seems better

lemme try just do -static before compiling and see if it compiles

then check pkg-config

[karmic viper]

Even if it happens to work now, it's not supposed to work in general

[hexed isle]

ye doesnt compile

ok so i did this

lemme try copy

it compiled with -static flag now 🔥 @karmic viper

wait so how to use pkg_config again ?

[karmic viper]

Wdym, you just used it?

[hexed isle]

i mean if i needed other stuff

like what it does is search what dependencies another dependency is using

[karmic viper]

The library names you pass to it, like absl_log and protobuf, correspond to files in C:\msys64\mingw64\lib\pkgconfig

So e.g. when you give it absl_log, it loads the flags from the file named absl_log.pc in that directory. Most libraries include those .pc files

[hexed isle]

ah

thanks bro i thought i will never solve it

well

if i wanna include zlib

do same steps if i get any error

[karmic viper]

Yeah, same steps should work.

https://packages.msys2.org/packages/mingw-w64-x86_64-zlib here you can see that it includes zlib.pc, so pkg-config should understand zlib once you install this package

[hexed isle]

pacman -S mingw-w64-x86_64-zlib

seems like its already installed

if i wanted to include it

just do

-lzlib ?

[karmic viper]

Run pkg-config --libs --cflags zlib and see what it tells you

[hexed isle]

alr

just

-lz

lol zed and vscode are cooked

i think they use clang

[delicate seal]

@hexed isle Has your question been resolved? If so, type !solved :)
