no_std error #186

First of all you'll need the nightly compiler for Second, I'm not very sure where that error came from. I've pushed the latest changes into master. You can try pulling it again to see if it solves your problem. Third, from the error message, it looks like you're compiling for an ARMv7 target ( From https://gist.github.com/adamgreig/b47fe9159e721e368601 it looks like you might need to install |
|
Im sure nigtly is on I even set it to default. I tried new version but it didnt worked. Also when I remove rhai project builds successfully. I think problem is on core-error libary, I removed rhai and imported core-error like in rhai's cargo.toml It gave me same error. |

How about the compilation target |

I tried installing with

I used --verbose option maybe this can help |

Looks like Try: core-error = { version = "0.0.0", features = ["alloc"] } |
|
It worked :D core-error = { version = "0.0.0", features = ["alloc"], default-features = false}using with |
|
That is because features are additive. Rhai only pull in |
|
Oh, I get it Im new in rust :D. Thank you for help. |
|
Just out of curiosity, may I ask what you're planning to use Rhai for on this microcontroller? |
|
Im trying to create a retro console which will use arm. With rhai I will give users a easy way to create games. |
|
You may find that Rhai doesn't run fast enough to create video games though... it is an interpreter. You might way to go with Lua or others. For text-based or other simple games which do not require lots of CPU power, Rhai should be OK. |
|
Games will be realy simple just like commodore games lines pixel arts etc. I actually don't know hardware is capable of doing theese. Im just prototyping it |
|
Sorry for asking again but, I didnt realy tried installing again. I tought if I set the |
|
You do not need Do you see the same error? What if you turn on verbose mode in cargo? |

For some reason |

Is it problem with |

Try compiling the I just did it on my PC and it worked. Obviously I'm not cross-compiling to ARM... |

This one looks better. It doesn't pull in |
|
So, are you gonna change Cargo.toml in rhai? |
|
Rhai only pulls in But let me change it to also put in |
|
Can you pull from my latest and see if it works now. I've taken care not to pull in |
|
It works fine now Thank you a lot! |
|
Hi |

First of all, thanks to help me! About this |

ok! Thank you @schungx |

Frankly speaking, I myself do not use |

well, i wrote many blogs to microcontrollers, circuitpython, micropython, lua, arduino, rtos, etc; now i want to write about RUST. Yes, i will do your suggestion! |
|
but, please |
|
All I know is... So I suggest you start with something bare minimum that works, something with rhai, which compiles and runs. Then add Rhai to it. |
|
@tcpipchip how is this working out for you? |

hi @schungx How are you ? Still tryng to solve that problem! tryng to install probe-run |

Hi, thanks to the feeback |

OK, closing this one for now. Feel free to open up another issue if there is a problem. |

Getting good progress in the rust programming! |
