Error: logical not is only applied to the left hand side of comparison

kgray9 · August 11, 2023, 7:06pm

Hi all!

I am making an anemometer project! It connects to wifi (if the network is available), and starts a AP on startup, that way I can see the webpage that displays the wind speed. Fairly simple, right?

Now, I just added Adafruit_IO to it, that way I can see past wind data on a chart, but it fails to compile! I kind of understand the error, but I am not sure why or how it is caused, or how to fix it.

Here is the error:

/Users/user/Documents/Arduino/libraries/ArduinoHttpClient/src/HttpClient.cpp: In member function 'int HttpClient::startRequest(const char*, const char*, const char*, int, const byte*)':

What do you think the "!" is supposed to do?

What logical comparison did you have in mind?

kgray9 · August 11, 2023, 7:15pm

Hi @jremington !

The "!" is a logical not. For example,
if(!wificonnected){//run code if wifi isn't connected}

The logical comparison seems to be in the ArduinoHttpClient library in the HttpClient.cpp file. It seems that the comparison is for checking if a client isn't connected.

There was no error before I tried adding Adafruit_IO. The previous code is running right now on the anemometer just fine.

jremington · August 11, 2023, 7:17pm

Yes, of course, but what do YOU expect it to do?

Do you expect the function return value to be less than zero?

kgray9 · August 11, 2023, 7:18pm

Of course not. The return value should be true (1) or false (0).

Why do you ask?

jremington · August 11, 2023, 7:19pm

I'll try again. What is the ">0" supposed to doing?

kgray9 · August 11, 2023, 7:20pm

I just went back up and reread the error before your response. I was just going to ask you why there is a ">0" and a "!" in the same if statement .

Couldn't the ">0" just be deleted?

jremington · August 11, 2023, 7:22pm

Only you know what should happen. Write the if logic accordingly.

kgray9 · August 11, 2023, 7:23pm

I'm not really sure what should happen . The error is inside the library.

kgray9 · August 11, 2023, 7:24pm

I'm confused @gcjr, sorry.

oqibidipo · August 11, 2023, 7:25pm

It should be

if (!(iClient->connect(iServerName, iServerPort) > 0))

and it has been fixed in version 0.5.0.
https://github.com/arduino-libraries/ArduinoHttpClient/releases/tag/0.5.0

kgray9 · August 11, 2023, 7:31pm

Thanks @oqibidipo for spoon feeding that to a dummy over here .

Thanks @jremington for trying to walk me through the logic! I really appreciate that.

kgray9 · August 11, 2023, 7:32pm

I just fixed that, and now I have a whole list of almost the same issues .

What on earth happened here?

You probably have two copies of the library that are now in conflict. Delete the old one.

Apparently, there was an entire second copy of all the library files (all ending with a 3) inside the library folder . I deleted them, and it compiles fine now! Thanks @jremington!
