I just installed Arduino 1.8.3 and I am getting the compilation error:
avr-g++: error: cannot access device-specs for 'atmega328p' expected at 'device-specs/specs-atmega328p'
Boar is nano, serial com connection OK, OS=system w10 64b -
The error happens just during compilation.
How to fix that? I have read something that this is due to gcc issue with the folder sequence but I am no th expert.
Please help.
I also have this problem, were you able to find a solution?
When attempting to upload the classic blink program (but the error appears with any program) to my Arduino Uno I get the following error (verbose information included):

Error compiling for board Arduino/Genuino Uno.
And here is some info from my computer:
OS Name Microsoft Windows 10 Home
Version 10.0.14393 Build 14393
OS Manufacturer Microsoft Corporation
System Manufacturer TOSHIBA
System Model Satellite L50-C
System Type x64-based PC
The fixes I have tried:
Restart Computer
Uninstalling Arduino, Deleting Appdata\Local\Arduino15 folder, Restarting Computer, Reinstalling Arduino
Running it also under Visual Micro
Turning off Firewall from my Antivirus software (McAfee)
Has anyone got any ideas on this one?
Did you download it from the website or via the Windows App store? If the latest, uninstall, delete the AppData and just download the installer form the website.
PS @owndbyu777, there is a major Windows update waiting for you 
I installed it from the website, Second installation - the same error.
I found somehere that this is gcc issue , it expects the uC spec in the first searching folder, so maybe if I copy uC spec into that folder it will work, but the question is : where is that folder?
Just found something:
avr-gcc expected to find the device specs in the search paths specified. But
it doesn't work as expected when device specs in different place than the
installed location.
I think I may have many avrgcc folders ,as I have avr studio also.
SO how to find the initial "the installed location" - it must be configured somewhere....
another thing tha may help to investigate the issu: I wrote the win c== console app to captur command line arguments from avr gcc. See the result below:

Do this:
Finally I found the workaround:
in short (it took me good few days of frustration)
inside the ARDUINO folder locate following file:
d:\My\AVR8\Arduino\hardware\arduino\avr\platform.txt
(your location may differ)
add path to the 4.9.2 folder of your Arduino installation:
[....]
compiler.cpp.extra_flags= -v -B d:\My\AVR8\Arduino\hardware\tools\avr\lib\gcc\avr\4.9.2\
[....]
then run Arduino as an Administrator (from windows).
I think the issue is related to the (1) Arduino and(2) Windows security.
My advises: No PATH (windows enviromet) to poin to any gcc location
So on my PC I have Arduino 1.8.3, AVR studio 7.0 and old WINAVR2010 with CodeBlocks - and everything work.
let me know if this helps
Greg
I seem to remember there was an issue with "codeblocks" some time ago co-residing with an IDE.
If you can try uninstall that and clean up afterwards just to check.

Did you read my post? Everything works now, the issue is fixed, so why do you recommend me to uninstall anything?
And it is very common and annoying when looking for help that most advises are to uninstall and install again.
Regardless...
It was a topic that was relevant !
The thing is that you shouldn't need to hardcode that path. The Arduino IDE should automatically know where avr-gcc is located. So even though it's great you got things working, it's kind of a hack. It would be best to find the true cause of the issue instead of a workaround but if the code is compiling and you're happy that's all that really matters.
Sorry about my late reply to this, I ended up just using my wifes computer to get done what I needed to do, and then got hit with heaps of stuff at work and uni...

Thanks for that Greg it definitely put me in the right direction! It wasn't the exact fix for my case but I think it led me to my fix...
After mucking around a little bit this afternoon I remembered I had to download heaps of stuff for uni and one of the things was a compiler called cygwin... I was looking around in the error messages I was getting when trying out your fixes and saw that name in there so I ended up uninstalling the stuff I had installed for uni this semester, deleted the extra stuff I added in Environment Variables, uninstalled Arduino, deleted my local install folder in Program Files, deleted my AppData/Local/Arduino15 folder, updated Arduino to 1.8.4, and it all works!
Not 100% sure the exact fix, but something in that did it! I can now compile and run programs on my Arduino from my computer!
Thanks for all your help,
Dave
In your case the fix was deleting the arduino15 directory

Good to hear yours IDE is working now.
Now, I am nearly sure the most important things to fix that issue was to run Arduino in admin mode (equivalent to some security windows settings to be alerted).
Hopefully they fix this in 1.8.4 so no need for workaround.
