undefined reference to `RestClient::begin(unsigned char*) #7

Closed derchirurg closed 5 years ago

derchirurg commented 6 years ago

Hi,

I get the following error when using (compiling with) the library: undefined reference to `RestClient::begin(unsigned char*)

How can I fix it?

DaKaZ commented 6 years ago

Can you post any more code or a more complete stack trace? I don't have enough information to answer your question. Thanks

I think the issue is: RestClient.cpp does not implement begin(...)

DaKaZ commented 6 years ago

Can you check the contents of D:\mm\Documents\Arduino\libraries\esp8266-restclient/RestClient.cpp to make sure it matches this library's RestClient.cpp? Our line 80 is very different than what your error is reporting.

derchirurg commented 6 years ago

If I check your RestClient.cpp at master branch, the method begin() is missing. So this cannot compile. I'm now using this lib: https://github.com/fabianofranca/ESP8266RestClient

ProximaB commented 6 years ago

So first you're writing code then check if library support it. 🤔

derchirurg commented 6 years ago

Don't understand. The library does not compile at all. I just give it a try. I expected the lib will compile if it is checked in. I did not review the code.

Not sure there is anything that needs to be done here. Please create a new issue if you need additional help.

Thanks
