It seems there is some kind of regarding relocatable code and the LEPTON_SDK.a library.

/usr/bin/ld: ../grabber_lib/Lepton_SDK/lib/LEPTON_SDK.a(bbb_I2C.o): relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC

I do not have this error... I follow the suggestion and I recompile with -fPIC

@jadonk Possible solution with commit https://github.com/Myzhar/Lepton3_BBB/commit/c0786a77e677ad22685225ce75a4460e072ff6da

@jadonk have you tried to add the -fPIC flag to your CMakeFiles.txt. I think that the problem is with your configuration...
