4 years ago Strange. Trying to create a minimal repro lead me to this:
Super_Simple_RGB_WiFi_Lamp.ion
void setup() {
a();
}
void loop() {
}Config.ino
void a() {
}Results in:
/home/lm/git/lm/brettl/Super-Simple-RGB-WiFi-Lamp/Super_Simple_RGB_WiFi_Lamp/Super_Simple_RGB_WiFi_Lamp.ino: In function 'void setup()':
Super_Simple_RGB_WiFi_Lamp:2:5: error: 'a' was not declared in this scope
a();
^
exit status 1
'a' was not declared in this scopeIt works once I add the forward declaration before the setup function:
void a();Strange. Really seems the IDE fails to add those forward declarations.

Describe the bug
I am unable to compile the sketch using arduino-1.8.10 on Ubuntu 18.04.
To Reproduce
Expected behavior
The sketch compiles.
Additional context
I haven't worked with the Arduino IDE for a while, but if I understand it correctly, the ino files are glued together and then compiled. The ino IDE should have been compiled with /tmp/arduino_build_241219/sketch/Super_Simple_RGB_WiFi_Lamp.ino.cpp at the top of the compiled file, so that forward declarations of the functions are known throughout the namespace. But I don't find these forward declarations in this file.
I just don't understand if this is a consequence of the environment, e.g. an incompatibility of the libraries or similar.
Can you give me a hint?
