What is the recommended way to install the library uWebSockets (https://github.com/uNetworking/uWebSockets) and be able to compile the accompanying examples ? I have tried the solution provided here: How to install uWebSockets? with no success: I ran the file install-linux.sh (see link above), the installation worked (no error message). Then, when I try to compile the example HelloWorld.cpp (see https://github.com/uNetworking/uWebSockets/blob/master/examples/HelloWorld.cpp), with:
g -std=c 17 HelloWorld.cpp
I get:
HelloWorld.cpp:1:10: fatal error: App.h: no such file or directory
So, my questions are:
- How do I correctly install the library,
- What exact command should I use to compile the examples ?
I am using g with Ubuntu 20.04 LTS.

I did this:
git clone --recurse-submodules [email protected]:uNetworking/uWebSockets.git
cd uWebSockets
WITH_OPENSSL=1 make examples
It built all examples, including HelloWorld, clean.
If you want to use WolfSSL instead, then make the examples using this instead:
WITH_WOLFSSL=1 WITH_LIBUV=1 make examples
If you want to install the uWebSockets header files together with other libraries you've downloaded:
make DESTDIR=$HOME/.local prefix= install
The uSocket sub module doesn't seem to get installed - or have a proper installation procedure so you'll have to do some digging to find out which headers are needed (if any). Building the examples produced some uSocket libraries though:
./uSockets/boringssl/util/ar/testdata/linux/libsample.a
./uSockets/boringssl/util/ar/testdata/mac/libsample.a
./uSockets/uSockets.a
These should probably be copied to where you store other third party libraries ($HOME/.local/lib perhaps). I assume you need to link your uWebSockets apps with uSockets.a. You can probably figure out how by looking at the examples.
