Compile errors

[xpix]

Hello,

i love this idea and want test the Homing Feature on a smoothieboard. But first of all i try to compile the grbl-lpc on my cloud9 workspace, but:

I removed
-std=gnu++14 and "atomic" include in debug.h, but run in the next error.
I think i'm wrong :)

Can somebody help me to install the correct packages

[tbfleming]

atomic comes with newer gcc versions

[xpix]

Ok, compile local in my windows system with arm toolchain works very well. One little thing:
grbl-lpc/current_control.cpp:67:47: error: 'round' is not a member of 'std' uint8_t(std::min(255.0, std::max(0.0, std::round(amps * CURRENT_FACTOR)))), ^

I renamed this to => 'round(..)' and it works ... nice.

@xpix I want to compile GRBL-LPC for CoreXY. What tools did you install to get it working. I make make and gcc-arm-non-eabi installed but when I make, I get a compile error

Before you can make, you need to run 'git submodule init' and 'git submodule update' (as written in README.md)

I had the same error regarding 'round'.
grbl-lpc/current_control.cpp:67:47: error: 'round' is not a member of 'std'
No relation to submodule updates in this case as neither of the submodules for GRBL-LPC include GCC and this was a known GCC bug. Need to make sure you're using the latest version of GCC (arm-none-eabi-*).

Download and install the toolchain. If windows 10, manually add path to the toolchain to your PATH. If windows 7, you can probably just select "add to path" option in the installer. Today, the most current version installs to "C:\Program Files (x86)\GNU Tools ARM Embedded\6 2017-q1-update", which is what you add to PATH. This is the proper way of fixing this error. Hope this helps someone! I wish the build documentation for GRBL was better. It's terrible for TinyG and G2 as well.
