Re: Onion Community Guidelines & Terms of Service
I am exploring the use of the Omega Dashboards for industrial controls applications,
My interest is to develop in C++, I have followed all your suggestions and articles related to cross-compiling with docker container.
the github clone that you have published has inconsistencies in the libs, after extensive work I achieved a set without errors, however when compiling with: g++ main.cpp -o lvgltest
I got the nest list of errors:
/tmp/ccz5xXaq.o: In function lv_scr_act': main.cpp:(.text+0x5): undefined reference to
lv_disp_get_default'

Can you help me with any recommendations? Do you have an update of the set of programs, without errors, for c++ cross compile?
Thanks
