Code won't compile with u8g2 #218

Closed nmeurer closed 2 months ago

nmeurer commented 4 months ago

Hi there, after searching for quite some time, I still can't find the issue. My main strength also isn't in programming so any help would be very much appreciated.

Describe the bug A clear and concise description of what the bug is. I can't get the generated code working. I modified nothing and just made changes in the editor.

Confirm that the bug is in the embedded library I interpret the given error as a bug in the library, but I am by no means an expert.

To Reproduce Please include a simple sketch that recreates the problem unless the problem is so easily recreated that such a sketch is not needed. Create any menu using the u8g2 quickstart with these settings:

Expected behavior I expected the code to compile

Screenshots If applicable, add screenshots to help explain your problem. Compiler error message: Screenshot 2024-06-21 004732

Device Specs An arduino mega with a ST7920 128x64 attatched via hardware SPI

Additional context I also tried using the manual u8g2 setup, but I don't seem to get it right. I'd love to see an example of how it is supposed to be done.

Regards

Hmm... It works for me. Check the contents of *_menu.h. It should contain a variable like this:

extern U8G2_SSD1309_128X64_NONAME0_F_HW_I2C gfx;

Then check *_menu.cpp whether you can see an initialization code.

U8G2_SSD1309_128X64_NONAME0_F_HW_I2C gfx(/*some parameters*/);

Third, make sure *_menu.h is included within *_menu.cpp.
