Compiling on PlatformIO

[AAKFISHERMANN]

HI, i tried to compile this code on Atom PlatformIO. Using different espressif32 platform versions (1.7.0, 1.8.0 and the last 1.12.4) i have the same error at the end of compiling;

Linking .pio\build\esp32doit-devkit-v1\firmware.elf
.pio\build\esp32doit-devkit-v1\src\main.cpp.o:(.literal.startup._GLOBAL__sub_I_NMEA2000+0x10): undefined reference to vtable for tN2kDataToNMEA0183'** .pio\build\esp32doit-devkit-v1\src\main.cpp.o:(.literal._Z4loopv+0x4): **undefined reference to tN2kDataToNMEA0183::Update(tBoatData)'*
.pio\build\esp32doit-devkit-v1\src\main.cpp.o: In function loop()': main.cpp:(.text._Z4loopv+0x39): **undefined reference to tN2kDataToNMEA0183::Update(tBoatData*)'**
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32doit-devkit-v1\firmware.elf] Error 1

Is there some kind a problem in one library?
Thanks

Hi, I don’t use this environment. Regarding problems with the libraries you should check this with the author of the libraries, Timo Lappalainen. Regards Andreas

Sometimes it is quite funny the behavior of the different ESP32 chips. Errors when loading the programs maybe caused by too much current load or too long USB cables. Some chips need lower loading speeds and or pushing the boot button...
