I think it is related to this error when I build IXWebSockets where was failed to build libzlibstatic.a:

Building IXWebSocket 11.4.5 with MBed-TLS 2.28.9 was solved. The path to libzlibstatic.a was incorrect - lib must be changed to libs:

I tried to solve them by adding libcrypto.a library from OpenSSL 1.1 folder but it didn't help:

target_link_directories(app PRIVATE C:/Qt/Tools/OpenSSL-1.1.1j/Win_x64/bin/ssl_1.1/x86_64)
target_link_libraries(app PRIVATE ixwebsocket mbedx509 ws2_32 mbedtls mbedcrypto crypto zlibstatic wsock32 SDL3::SDL3)

Added. the crypt32 library solved the problem! I have received a message from the Glitch.com and Render.com free Node.js hostings!

target_link_libraries(app PRIVATE ixwebsocket mbedx509 ws2_32 mbedtls mbedcrypto crypt32 zlibstatic wsock32 SDL3::SDL3)

P.S. So, MBed-TLS v2.28.9 must be used with IXWebSocket 11.4.5 but MBed-TLS v3.x.x have the mbedtls_pk_parse_keyfile function that requires 5 arguments (not 3)

error: no matching function for call to 'mbedtls_pk_parse_keyfile'
requires 3 arguments, but 5 were provided

So, I had this error with the latest IXWebSocket-11.4.5 and the latest Mbed-TLS 3.6.1: too few arguments to function 'int mbedtls_pk_parse_keyfile' I solved it by using MBed-TLS v2.28.9 instead of MBed-TLS v3.x.x. I have tried MBed-TLS v3.0.0 too but IXWebSocket-11.4.5 has the same error. So, the number of arguments of mbedtls_pk_parse_keyfile was changed in MBed-TLS v3.0.0 but IXWebSocket-11.4.5 uses the old version of MBed-TLS v2.x.x.

Download MBed-TLS 2.28.9 like this:

git clone --depth 1 --branch v2.28.9 https://github.com/Mbed-TLS/mbedtls.git

Set the installation path and configure it:

cmake -G "MinGW Makefiles" --fresh -S . -B dist -DCMAKE_INSTALL_PREFIX=E:/libs/mbedtls-2.28.9-prefix

Build it:

cmake --build dist -j4

Install it:

cmake --install dist

Install zlib with the same way. I use zlib v1.3.1. Download and install IXWebSocket-11.4.5 with the configuration:

cmake -G "MinGW Makefiles" --fresh -S . -B dist -DCMAKE_INSTALL_PREFIX=E:/libs/IXWebSocket-11.4.5-prefix -DZLIB_INCLUDE_DIR=E:/libs/zlib-1.3.1-prefix/include -DZLIB_LIBRARY=E:/libs/zlib-1.3.1-prefix/lib/libzlibstatic.a -DMBEDTLS_LIBRARY=E:/libs/mbedtls-2.28.9-prefix/lib/libmbedtls.a -DMBEDTLS_INCLUDE_DIRS=E:/libs/mbedtls-2.28.9-prefix/include -DMBEDX509_LIBRARY=E:/libs/mbedtls-2.28.9-prefix/lib/libmbedx509.a -DMBEDCRYPTO_LIBRARY=E:/libs/mbedtls-2.28.9-prefix/lib/libmbedcrypto.a -DUSE_TLS=ON -DUSE_WS=ON -DUSE_ZLIB=ON

This is my step by step guide to install SDL3 on Windows but it can be useful for MacOS too if you need a window Setting up SDL3 for Windows using CMake and MinGW-w64 You can draw GUI using ImGUI and SDL3: Building ImGUI statically and setting up it to the CMake project

Server:

app.js

const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', (ws) => {
    console.log('Client connected');

    ws.on('message', (message) => {
        console.log('Received message:', message);
        // Process the received message and send a response if needed
    });

    ws.on('close',
    () => {
        console.log('Client disconnected');
    });
});

Nice, thanks for sharing.

There should be an mbedtls version detection blob somewhere, as the API changed in 3.xxx.

cf c27f5a9

I tried to use the latest version of IXWebSocket 12.0.0 and mbedtls-4.1.0: #577

@bsergean

Hi @bsergean,

You are exactly right. The automated version detection didn't trip on my setup, but forcing the preprocessor definition during configuration resolved the build errors completely.

For anyone else using MinGW and Mbed TLS 3+ who runs into this compile error, you can fix it without modifying the source code by explicitly passing the macro flag to CMake:

-DCMAKE_CXX_FLAGS="-DIXWEBSOCKET_USE_MBED_TLS_MIN_VERSION_3"

My full working configuration command ended up looking like this:

cmake -G "MinGW Makefiles" --fresh -S . -B dist -DCMAKE_INSTALL_PREFIX=C:/libs/IXWebSocket-12.0.0-mingw -DZLIB_INCLUDE_DIR=C:/libs/zlib-1.3.2-mingw/include -DZLIB_LIBRARY=C:/libs/zlib-1.3.2-mingw/lib/libzs.a -DMBEDTLS_LIBRARY=C:/libs/mbedtls-3.6.6-mingw/lib/libmbedtls.a -DMBEDTLS_INCLUDE_DIRS=C:/libs/mbedtls-3.6.6-mingw/include -DMBEDX509_LIBRARY=C:/libs/mbedtls-3.6.6-mingw/lib/libmbedx509.a -DMBEDCRYPTO_LIBRARY=C:/libs/mbedtls-3.6.6-mingw/lib/libmbedcrypto.a -DUSE_TLS=ON -DUSE_WS=ON -DUSE_ZLIB=ON -DCMAKE_CXX_STANDARD_LIBRARIES="-lbcrypt -lcrypt32 -lws2_32" -DCMAKE_CXX_FLAGS="-DIXWEBSOCKET_USE_MBED_TLS_MIN_VERSION_3"

Building and installing:

cmake --build dist -j8
cmake --install dist

Since the compilation issue is fully resolved on my end, I will go ahead and close this issue. Thanks for pointing me in the right direction regarding the API change!

P.S. Building and installing Mbed TLS 3.6.6:

git clone --depth 1 --branch v3.6.6 https://github.com/Mbed-TLS/mbedtls.git
cd mbedtls
git submodule update --init --recursive
cmake -G "MinGW Makefiles" -S . -B dist -DCMAKE_INSTALL_PREFIX=C:/libs/mbedtls-3.6.6-mingw
cmake --build dist -j8
cmake --install dist
