The arm platform cannot load fonts. I need your help

[asdone7]

hello，

I can load fonts well under Ubuntu, but I can't load fonts when I use cross compilation to generate binary files for arm platform.

I added regular.ttf font in the way of "ImFont* font = io.Fonts->AddFontFromFileTTF". After the construction is completed, open the binary file, all the symbols displayed are "？"。
I checked the construction log and prompted me whether "void gui_init()': unused variable 'font'" is related to this. However, I also have this prompt when building under ubuntu, and it does not display abnormity

Thanks in advance.
