uWebSocket cmake

[ionic umbra]

I would be glad if you give me such tho. Mine is literally unbuildable.

Having something like this :

cmake_minimum_required(VERSION 4.0)
project(prj)

set(CMAKE_CXX_STANDARD 20)

add_executable(prj src/main.cpp)

#============================DOWNLOAD-WEBSOCKET-LIBRARY==========================
set(BUILD_SHARED_LIBS OFF)
include(FetchContent)
FetchContent_Declare(
        uWS
        GIT_REPOSITORY https://github.com/uNetworking/uWebSockets.git
        GIT_TAG v20.73.0
)
FetchContent_MakeAvailable(uWS)

# µWebSockets requires OpenSSL and zlib. Find them on the system.
# OpenSSL::SSL and OpenSSL::Crypto are used for secure connections (WSS).
find_package(OpenSSL REQUIRED)
find_package(ZLIB REQUIRED)

(... other libs, whatever)

#============================END-DOWNLOAD-WEBSOCKET-LIBRARY======================

target_link_libraries(prj PRIVATE
        OpenSSL::SSL
        OpenSSL::Crypto
        ZLIB::ZLIB
        uWS
)

what errors into this at compilation stage:

[ 11%] Built target asio
[ 58%] Built target spdlog
[ 64%] Linking CXX executable low_latency_daemon
/usr/sbin/ld: cannot find -luWS: No such file or directory
collect2: error: ld returned 1 exit status

linking it with uWS:uWS just fails just by the same way :

[ 11%] Built target asio
[ 58%] Built target spdlog
[ 64%] Linking CXX executable low_latency_daemon
/usr/sbin/ld: cannot find -luWS:uWS: No such file or directory

this is cmake

uWS not use cmake

did you even read makefile and build.c?

@ionic umbra

[ionic umbra]

cMakeLists* with bunch of cmakes for a project in a nutshell tho

[austere wolf]

are you sure you can

FetchContent_Declare(
        uWS
        GIT_REPOSITORY https://github.com/uNetworking/uWebSockets.git
        GIT_TAG v20.73.0
)
FetchContent_MakeAvailable(uWS)

?

look at build.c

[ionic umbra]

There is no information on how to set it up at all

[austere wolf]

it clearly just build from .a and sources

btw i see no windows signature

is uWS unix only?

[ionic umbra]

Feels like so

[ionic umbra]

Based on what I've read right now from one of issues, this is possible to build on windows
Hey! I’m not sure if you still need help, but just in case — you can use the vcpkg package manager to install uWebSockets much more easily than doing it manually. Setting it up by hand usually requires multiple tools like Microsoft Build Tools, OpenSSL, zlib, and other essential libraries, plus manual environment configuration.

[austere wolf]

yes it have win signatures, but only in source

[ionic umbra]

Btw, I need this thing on a unix system

Thank you and let us know if you have any more questions!

the library doesn't seem to have cmake whatsoever, just build usockets manually and add include paths and link

uwebsockets itself seems to be header only, you don't need to do anything other than set up include paths

[ionic umbra]

No, it seems to be bloated cruise ship with ~1.3GB (with subrepos) in size and is planned to handle millions simultaneous connections

[vocal trout]

nothing i said has anything to do with “being bloated”

[austere wolf]

uSocket sublib used to make examples have TU's

but seems like it only non-header-only-lib

 strcat(CXXFLAGS, " -march=native -O3 -Wpedantic -Wall -Wextra -Wsign-conversion -Wconversion -std=c++2b -Isrc -IuSockets/src");
    strcat(LDFLAGS, " uSockets/*.o");```
