linux - MQTT Auth 插件 - 构建问题

Question

我正在尝试构建 MQTT Auth Plugin和面临的问题。我已按照@ http://www.yasith.me/2016/04/securing-mqtt-connection-using.html 提供的说明进行操作为此。这是我得到的错误 -

Using mosquitto source dir: /home/vagrant/Repos/mosquitto/mqtt/mosquitto
OpenSSL install dir:        /usr/bin

If you changed the backend selection, you might need to 'make clean' first

我的 config.mk 文件看起来像 -

BACKEND_CDB ?= no
BACKEND_MYSQL ?= no
BACKEND_SQLITE ?= no
BACKEND_REDIS ?= no
BACKEND_POSTGRES ?= no

BACKEND_HTTP ?= yes
BACKEND_JWT ?= no
BACKEND_MONGO ?= no

# Specify the path to the Mosquitto sources here
MOSQUITTO_SRC =/home/vagrant/Repos/mosquitto/mqtt/mosquitto

# Specify the path the OpenSSL here

# Specify optional/additional linker flags here
LDFLAGS =

我在 LINUX 虚拟机( Vagrant )上执行此操作 - 不知道这是否会有任何不同。我能够看到所有 apt-get 都按预期安装了软件包。

有什么建议吗？

我相信这取决于您使用的 openssl 版本。 EVP_MD_CTX_new() 仅适用于 openssl 1.1.0。
