Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I read through troubleshooting guide, and updated FTDI chip driver. I keep getting collect2 error. Mac OS X Lion 10.7.5.

Thank you

Enable verbose compile output in settings, try a compile, and post the full text of the error here. I have never seen that error before.

Please enclose it in code tags using the </> button so it's easier for people to read (per how to use this forum thread - see that for more info if needed)

Does the error occur with 1.6.12? I see that you're using an hourly build - if you want the IDE to work, you should use a released version, not the hourly builds. The hourly builds are frequently busted.

Reply: yes error is still present with 1.6.12. I also enabled verbose as requested. Hope I have included all that is required.

Thank you

Weird - the compiler's choking as it tries to load the lto plugin, complaining of missing symbol.

I would suggest editing title of thread to something like:

Mac OS compile error: Symbol not found: _environ

The issue has a distinct and unusual error message, and it has nothing to do with uploading - that's the compiler barfing. People generally aren't inclined to help someone with a generic "it won't upload" thread - 9 times out of ten, you click it and they've got a sync error and no clue (because it's their first arduino) - trying to help people with that is rarely a rewarding experience. But your error is a weird one, certainly more interesting - and probably something that has a single solution that we can give the next guy.

Tks advice implemented.

Have the same issue with this version on MacOS 10.7.5.
So i downloaded an older version of Arduino IDE 10.6.3 which runs okay.

7

Same issue error: OSX, 1.8.0 IDE, AAVR 1.6.16, compiling the default void/void sketch

8

I have the exact same issue..

9

I'm on 10.7.5 and need to compile 'Marlin' reprap code.

Marlin requires Arduino IDE >=1.6.8, however 1.6.8+ doesn't compile on Lion.
It has the error identified above.

Has anyone found any solutions to this issue yet?
Thanks.
Paul.

Having the same issue Mac OS X 10.7.5 with unoR3. Did anyone find a solution for this problem?

I found an answer:

pert:
You should be able to fix this by:

  • Tools > Board > Boards Manager > Arduino AVR Boards(click on it) > select 1.6.11 from the "select version" drop down menu > Install
  • Wait for the installation to complete and then click the "Close" button

As to the actual cause of the issue I don't know. The LTO stuff that's causing the issue was added in Arduino AVR Boards 1.6.12, this is why you need to go back to Arduino AVR Boards 1.6.11 to fix it.
