Dear @anil_azkin ,
as pointed by Dávid, the solution provided here works for M1 chip.
For your convenience, I report here the instructions
make clean
make -j 8 DEBUG=yes
make install DESTDIR=<path to flair>
and be sure that the geoviewer.so file inside the Flair folder is the same as in the geoviewer folder.
Sometimes MacPorts installation might be corrupted, so a more drastic approach would be to clean the installation
sudo port uninstall installed
sudo port claim (answer yes to all questions)
and then reinstall python3.7
sudo port install py37-matplotlib +tkinter
sudo port select --set python3 python37
Before performing the previous commands, I recommend you to save the list of requested ports, which would be useful to reinstall all other ports previously installed
port echo requested
If you still have problems, can you provide the output of the following commands:
which python3
port select --summary
c++ -v
and share the again the error log (it can be removed from Console application among Crash Reports?
Cheers Luigi
