I cannot compile my program ! I get the following error message :
exec: "C:\Users\papa\AppData\Local\Arduino15\packages\arduino\tools\avr-gcc\4.9.2-atmel3.5.3-arduino2/bin/avr-g++": file does not exist
Erreur de compilation pour la carte Arduino/Genuino Uno
How correct this ?
Regards
A bunch of people have had IDE 1.6.x problems, including IDE crashes and bizarre compile errors, when they had a previous 1.5.x/1.6.x installation. At least some of those problems seem to be caused by incompatible executables and preference files that the IDE saves outside the IDE installation directory. Perhaps that is what is causing your particular problem. In such cases it appears that the fix is to delete or rename the old "Arduino15" directory and re-install 1.6.x.
On Mac OS X:
/Users/(username)/Library/Arduino15 (a.k.a. ~/Library/Arduino15)
(Note: The 'Library' folder is greyed out in Finder. The folder can't be opened with a double-click. To browse the contents of 'Library', ctrl-click on it and select "Open in New Tab" from the pop-up menu.)
On Windows delete or rename both:
Arduino IDE 1.6.5r5 and previous: C:\Users(username)\AppData\Roaming\Arduino15
Arduino IDE 1.6.6 and later: C:\Users(username)\AppData\Local\Arduino15
On Linux:
/home/(username)/.arduino15 (a.k.a. ~/.arduino15)
(Note: file/folder names starting with '.' are not normally shown in directory listings. Use 'ls -a' to get a directory listing that includes the hidden files.)
I download today the 1.6.10 revision : it seems to work/compile correctly.
In the previous message, the error message contains some double anti-slash "\" in the path as below:
C:\ Users \ . . . .

1.6.10 is really flaky - lots of bugs from a bungled addition of a compiler update and avrdude update without proper testing. Broke tons of stuff.
1.6.13 and 1.6.9 are both much better.
