How to integerate this in Cmake based C++ project

[anuragvohraec]

Hi ,

I have tried various ways to integerate this into my Cmake based C++ project , without a sucess.

Steps followed:

1. I git cloned the project: git clone --recurse-submodules [email protected]:uNetworking/uWebSockets.git
2. I wanted to use the boringssl with libuv.
3. And hence first I build the boring ssl :

mkdir build
cd build
cmake ../
make

4. Then I made uSockets: WITH_BORINGSSL=1 WITH_LIBUV=1 make
5. And then tried building uWebSockets, by command WITH_BORINGSSL=1 WITH_LIBUV=1 make -f ./GNUmakefile

With gcc 10.4.0 its was not compiling, so I repeated the process with gcc: 9.4.0 (Built ssl > usockets > uWebSockets).
After which it successfully was build : ./HelloWorld example is running

I included the header files in my Cmake, and referenced the uSockets.a in my project. But still getting many errors.

Can any one summarize or give me link to how to embed uWebSockets to a C++ based project with boringssl and libuv event loop ?

My system specfications are:
OS: Ubuntu 20.04.5 LTS
GCC: 10.4.0

You literally hit "make" in the folder. That's it. It builds all the examples including uSockets.

It also literally prints the exact compiler invocation like so:

g++ -O3 -Wpedantic -Wall -Wextra -Wsign-conversion -Wconversion -std=c++2a -Isrc -IuSockets/src -flto examples/EchoServer.cpp uSockets/*.o -lz -o EchoServer

Which means that it becomes extremely easy and obvious what you need to replicate in <insert one of the 59 million different build systems for C++>. It is very rare for a project to be this clean in its invocation of the compiler, making it incredibly easy to understand and move into whatever environment or IDE or project file you may want.

OK managed to make it finally run. Thank you.

These are not uWS bugs, your compiler is broken. Report bugs to your compiler vendor, not here.
