teensy arduino linking problem after upgrade to PIO2.0

[gandy92]

Since upgrading to 2.0, I get an error when compiling a project for teensy3.1-arduino:

''' ../lib/gcc/arm-none-eabi/4.8.3/../../../../arm-none-eabi/bin/ld: cannot open linker script file /home/andy/.platformio/packages/ldscripts/mk20dx256.ld: No such file or directory collect2: error: ld returned 1 exit status scons: *\ [.pioenvs/teensy31/firmware.elf] Error 1 '''

already deleted .pioenv and even reinstalled everything from scratch, but to no avail.

what can I do?

Hi @gandy92

It seems ldscript package has been updated incorrectly. This file mk20dx256.ld should be in this directory: /home/user/.platformio/packages/ldscripts If it's not there, try to update your packages via platformio update. If this does not help, delete your appstate.json file from /home/user/.platformio and install teensy platform again.

Thanks, that helped - apparently, a few file permissions in ~/.platformio/packages got corrupted during a previous sudo platformio upgrade. After fixing the file permissions, deleting the appstate.json file and installing teensy platform during the next platformio run, my build system is back to normal.

@gandy92 Im glad to hear you! :blush:

Since PlatformIO 2.0 each upgrade operation to the new version will force platformio platforms update automatically. It should allow to avoid the similar problems like yours.

I'm not sure but I gather the problem was a sudo platform upgrade which not only upgraded platformio in /usr/local/ with root permissions, but also updated libs and packages residing in $HOME/.platformio with root permissions. This left some of the files (including packages/ldscripts) owned by root instead of myself, making it impossible to update the files or even whole subdirectories without sudo.

Next time I run into this kind of problem I know I have to check permissions in my ~/.platformio.

Would it be possible to check if platformio update is running with root permissions and fix file ownership in non-system directories?

I've just fixed it. PlatformIO will not run updating process for the packages/libs when user runs platformio upgrade command.

P.S: Since PlatformIO 2.0 automatic library/package updates were disabled by default.

Perfect, thanks! :+1:

Must have happened some while ago. I remember having encountered problems during some updates but each time, rerunning platformio update appeared to resolve the problem. Now, in retrospect, what really might have happened was that the appstate.json was updated without the complete update ever happening.

@gandy92 what do you think about new feature Continuous Integration in PlatformIO 2.0?
