How do I compile this project?

[skyformat99]

hi Want to try, how to compile it? thanks

[skyformat99]

The following method failed: aclocal autoreconf -i automake ./configure

[romuloceccon]

autoreconf -i && ./configure && make should be enough, provided you have the dependencies installed (autoconf-archive and check). What error message do you get?

P.S.: I've added a "Contributing" section to the README file explaining how to compile.

[skyformat99]

Success! thank you very much! This project is very, very cool ! ๑乛◡乛๑

The following files are in the .libs folder: -rw-rw-r-- 1 123536 Jun 28 08:17 liblightmqtt.a lrwxrwxrwx 1 18 Jun 28 08:17 liblightmqtt.la -> ../liblightmqtt.la -rw-rw-r-- 1 976 Jun 28 08:17 liblightmqtt.lai lrwxrwxrwx 1 21 Jun 28 08:17 liblightmqtt.so -> liblightmqtt.so.0.0.0 lrwxrwxrwx 1 21 Jun 28 08:17 liblightmqtt.so.0 -> liblightmqtt.so.0.0.0 -rwxrwxr-x 1 100356 Jun 28 08:17 liblightmqtt.so.0.0.0

1) are these .a .so files in Release version? 2) liblightmqtt.a --> static library, liblightmqtt.so.0.0.0 --> dynamic library? 3) I built the broker using apollo (http://activemq.apache.org/apollo/), but failed with the pingpong test because user password was needed in apollo broker. can you add user & password support in example code?

1) are these .a .so files in Release version?

It depends on the options you gave to configure. In my platform the default is -g -O2.

2) liblightmqtt.a --> static library, liblightmqtt.so.0.0.0 --> dynamic library?

Correct!

3) I built the broker using apollo (http://activemq.apache.org/apollo/), but failed with the pingpong test because user password was needed in apollo broker. can you add user & password support in example code?

Later I'm going to add some command line arguments in the examples to configure client credentials. Meanwhile you can use something like the following to make your tests. Let me know if you have any problem!

Thank you for your reply. Modify the code according to your prompt, the connection is ok, but there are errors in the ping pong test.

/home/mqtt/lightmqtt/build/examples$ ./pingpong -h 192.168.2.55 -p 61613 -i pong -t ping pong (0): st client: error

/home/mqtt/lightmqtt/build/examples$ ./pingpong -h 192.168.2.55 -p 61613 -i ping -t pong -m test ping (0):

[romuloceccon]

Ok. I'll try the examples using the Apollo broker later this week and find out the problem. Thanks for the feedback.

[romuloceccon]

@skyformat99, the issue you experienced was due to an incorrect implementation of the MQTT 3.1.1 spec regarding the handling of QoS 0 messages. It's now fixed in commit b9da4109bbe307f6c99fba2ae7f2b7bdfec41e1b.

Incidentally, the bug became evident because the Apollo broker also seems to not follow the specs correctly: even when receiving QoS 2 messages it forwards them using QoS 0.

[skyformat99]

thanks，I will try again。😃

[skyformat99]

@romuloceccon Thank you. That's ok. btw, Can you add automatic connect function? For instance, When the broker restarts, ping/pong test cannot auto connect to the broker server.

like as: typedef void (lmqtt_client_on_disconnect_t)(void , lmqtt_connect_t *, int);

[skyformat99]

In addition, can use macro definitions in code? thanks.

/**

• The available QOS levels. */ typedef enum { LMQTT_QOS0 = 0, LMQTT_QOS1 = 1, LMQTT_QOS2 = 2 } lmqtt_qos_t;

[romuloceccon]

@skyformat99, could you please open separate tickets for those requests?

[skyformat99]

ok, close it.
