> Closing, because documented alternative exist. There's a documented alternative for specifying compiler flags from within the sketch's directory? I apologize for necro-ing this thread, but if that's the case...

Just wanted to bump this PR as this would be an immensely useful addition. I see that the last mention of this was nearly 2 years ago. What more needs...

@h2zero Please let me know if there are any tests or other things I should try. I'm convinced this is just a mistake on my end, since it seems to...

Yes it is, but I just did a quick `cat * | grep min` and the same for `max` and I haven't redefined them, or even used them as a...

Oh boy, I think I've found it: https://arduinojson.org/v6/error/macro-min-passed-3-arguments-but-takes-just-2/ Looks like `Arduino.h` and `std::min` conflict. I'll see if I can fix this by changing the order of the `#includes`.

Reordering does partially fix things, but still produces compilation errors from `min` and `max` in `h2zero/hardware/arm-ble/0.1.1/cores/nRF5/Arduino.h`. Specifically the whole error is: ``` /home/pcook/.arduino15/packages/h2zero/tools/gcc-arm-none-eabi/9.3.1-1/arm-none-eabi/include/c++/9.3.1/bits/stl_bvector.h: In member function 'std::vector::size_type std::vector::_M_check_len(std::vector::size_type, const char*)...

I have confirmed that the issue is indeed in the `Arduino.h` definition of `min` and `max.` Commenting those lines out results in error-free compilation.

@h2zero It's unclear to me how exactly they fixed it in the samd core. Something to do with the underlying arduino-api. But here a permanent (albeit a bit sloppy) fix...

Can confirm this issue in native, LXC container, and docker installs. Seems the plugin is completely broken at the moment.
