Hello,
I had this manufacturer error when generating the FMU:

model_moyenne_me_FMU_01exo.o: model_moyenne_me_FMU_01exo.c . text + 0x1f): undefined reference to `omc_model__moyenne__me__FMU_FMI2ModelExchange_destructor '
collect2.exe: error: ld returned 1 exit status
model_moyenne_me_FMU.makefile: 32: recipe for target 'omc_main_target' failed
mingw32-make: *** [omc_main_target] Error 1
mingw32-make: Leaving directory 'C: / Users / F379876 / DOCUME ~ 1 / Project / EXEMPL ~ 1 / MODEL_ ~ 2 / MODEL_ ~ 1 / MODEL_ ~ 1'
Compilation process failed. Exited with code 2.

Thank you for your help.
