Stupid Library Compile Warnings!!!

PubSubClient (2.8.0)

.pio/libdeps/SugarBush_SS_Climate_BME280/PubSubClient/src/PubSubClient.cpp: In member function 'boolean PubSubClient::publish_P(const char*, const uint8_t*, unsigned int, boolean)':

.pio/libdeps/SugarBush_SS_Climate_BME280/PubSubClient/src/PubSubClient.cpp:523:19: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]

     return (rc == expectedLength);

                   ^

FIX: Add unsigned to the definition of expectedLength

SimpleTimer (0.0.0-alpha+sha.b30890b8f7)

.pio/libdeps/SugarBush_SS_Climate_BME280/SimpleTimer/SimpleTimer.cpp: In member function 'void SimpleTimer::run()':

.pio/libdeps/SugarBush_SS_Climate_BME280/SimpleTimer/SimpleTimer.cpp:66:60: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]

 if (current_millis - prev_millis[i] >= delays[i]) {

                                               ^

FIX: Add unsigned to the definition of delays[]

Troubleshooting

When trying to compile things on a Linux machine...

You get silly-ass errors like fatal error: stdio.h: No such file or directory or other files missing that just don't make ANY sense...

• sudo apt update
• sudo apt install --reinstall build-essential

'Coz sumpin' borked yer compiler install...
