Unable to send data to libwebsocket server

问题 I'm trying to write a small plugin for X-Plane, to create a simple websocket server with libwebsocket. I'm able to connect to the websocket from Google Chrome, however, when I send data to the server, X-Plane immediately crashes. I'm pretty certain the following code is causing the problem: unsigned char *buf = (unsigned char*) malloc(LWS_SEND_BUFFER_PRE_PADDING + 13 + LWS_SEND_BUFFER_POST_PADDING); buf = (unsigned char*) "Hello World!"; libwebsocket_write(wsi, buf, len, LWS_WRITE_TEXT); free

Compiling libuv with libwebsockets

由 邮差的信 提交于 2019-12-10 18:36:00
问题 I am trying to run the "libwebsockets-test-server" that is installed with the LWS library, but it will not run because "lwsts[31616]: libuv support not compiled in". I have checked that libuv is installed (1.8.0). I also changed the setting for LIBUV in cmake and recompiled the library. LWS_USE_LIBUV = 1 How do I get the project compiled with libuv? I am on Ubuntu 16.04, cross-compiling using arm-linux-gcc. I have successfully compiled programs, loaded them to the embedded board (TS-7800),

Setting CLion build and binary directory

问题 I'm trying to build libwebsockets inside of my project in CLion. During build libwebsockets creates a header file that is required by other files and puts it in PROJECT_BINARY_DIR.

I've tried: Setting the websockets_BINARY_DIR variable Setting the CMAKE_RUNTIME_OUTPUT_DIRECTORY variable Setting CMAKE_LIBRARY_OUTPUT_DIRECTORY variable Changing every variable in the

系统版本centos7 X64 1.设置保存安装包路径 # cd /usr/local/src 2、开始下载源包 官网资源： https://mosquitto.org/files/source/ # wget https://mosquitto.org/files/source/mosquitto-1.6.7.tar.gz 3、解压 解压后得到mosquitto-1.6.7文件目录 # tar zxvf mosquitto-1.6.7.tar.gz# mv mosquitto-1.6.7 /usr/local/mosquitto-1.6.7 4、安装MQTT运行依赖环境 1） 以下三个必须安装，不然make时无法通过。 另外安装MQTT之前，我们也可以# cat compiling.txt文件阅读一下官方的说明。 # yum -y install openssl-devel # yum -y install gcc-c++ # yum -y install cmake 2） 以下可选扩展功能，不安装也不影响MQTT使用，只是缺少部分对应的功能 c-ares（用于DNS-SRV支持，默认禁用）c-ares官网： http://c-ares.haxx.se tcp-wrappers（可选，包名libwrapp0 dev） lib-uuid（支持为每个连接客户端生成唯一uuid）
