Compiling the project

[JchenEng]

Hello,

I fairly inexperienced with the whole cmake software, but essentially I am encountering some issues compiling the project. I have followed the development environment (https://github.com/Lora-net/LoRaMac-node/blob/master/doc/development-environment.md). I am trying to use the CMake GUI (CMake 3.19.0), but I receive the following errors:

Please specify the TOOLCHAIN_PREFIX !
For example: -DTOOLCHAIN_PREFIX="C:/Program Files/GNU Tools ARM Embedded"
The C compiler identification is unknown
The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:18 (project):
The CMAKE_C_COMPILER:

/bin/arm-none-eabi-gcc.exe

is not a full path to an existing compiler tool.

Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

CMake Error at CMakeLists.txt:18 (project):
The CMAKE_CXX_COMPILER:

/bin/arm-none-eabi-g++.exe

is not a full path to an existing compiler tool.

Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

Where is the source code: "C:/Users/XXXXX/Desktop/Electronics/LoRaMac-node-master"
Where to build the binaries: "C:/Users/XXXXX/Desktop/Electronics/build"

I have tried adding a new entry called DTOOLCHAIN_PREFIX to where I installed the GNU tools ARM Embedded

but that did not resolve my issue.

Hi @JchenEng ,

could you please double check that you have defined every symbol which is available in the file ".vscode/settings.json"? E.g. have you defined -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain-arm-none-eabi.cmake?

In general, i would recommend to use VS Code which helps to have an easy start.

The README.md file provides the instructions on how to build the project at chapter Building Process

The commands example were provided to build periodic-uplink-lpp example for NucleoL476 platform with LR1110MB1DIS MBED shield and using LR1110 pre-provisioned secure-element.

This means that you need to adapt the command according to your needs.

$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release \
        -DTOOLCHAIN_PREFIX=""C:/9 2019-q4-major"" \
        -DCMAKE_TOOLCHAIN_FILE="../cmake/toolchain-arm-none-eabi.cmake" \

Hey everyone,

Sorry for the delay. I am using a NucleoL073 board with the radio shield (CWX1ZZABZ) which I believe is a SX1276MB1MAS.
@mluis1 I tried following the Building Process, but it returns the following error message:

I tried setting it up in visual studio code, but I get the following error compiler problem, do you know what I should look at to resolve it?
`CMake Error at C:/Program Files/CMake/share/cmake-3.19/Modules/CMakeTestCCompiler.cmake:66 (message):The C compiler

It fails with the following output:
