[异常解决] Make nRF51 DFU Project Appear "fatal error: uECC.h: No such file or directory"
What's the problem
When I make the nRF51's DFU project appear "no uECC.h" error:
And then find that: The uECC library is an external library that is not a part of the SDK and it must be installed by the user.
Installing micro-ecc
micro-ecc is an open source library that is required to use the cryptography library. When using micro-ecc, you must ensure compliance with the license of the library as stated in the LICENSE.txt file that is included in micro-ecc.
The cryptography library expects to find the compiled micro-ecc library in InstallFolder\external\micro-ecc\micro-ecc
.
To install micro-ecc, complete the following steps:
- Install version 4.9-2015-q3-update of the GCC compiler toolchain for ARM. You can use ARM's Launchpad to find the toolchain for your operating system.
- Make sure that make is installed (see, for example, MinGW, GNU Make, or Xcode).
- Clone the micro-ecc GitHub repository into
InstallFolder\external\micro-ecc\micro-ecc
. - Enter the subdirectory for the SoC and the toolchain that you are using to build your application:
InstallFolder\external\micro-ecc\nrf51_keil\armgcc
InstallFolder\external\micro-ecc\nrf52_keil\armgcc
InstallFolder\external\micro-ecc\nrf51_iar\armgcc
InstallFolder\external\micro-ecc\nrf52_iar\armgcc
InstallFolder\external\micro-ecc\nrf51_armgcc\armgcc
InstallFolder\external\micro-ecc\nrf52_armgcc\armgcc
- Run make to compile the micro-ecc library.
btfz@btfz-pc:~/Documents/nRF5_SDK_12..0_f012efa$ cd external/micro-ecc/
btfz@btfz-pc:~/Documents/nRF5_SDK_12..0_f012efa/external/micro-ecc$ git clone https://github.com/kmackay/micro-ecc
btfz@btfz-pc:~/Documents/nRF5_SDK_12..0_f012efa/external/micro-ecc/nrf51_armgcc/armgcc$ make
mkdir _build
Compiling file: uECC.c
Creating library: ../../nrf51_armgcc/armgcc/micro_ecc_lib_nrf51.a
/usr/bin/arm-none-eabi-ar: creating ../../nrf51_armgcc/armgcc/micro_ecc_lib_nrf51.a
Done
Another Problem
Now again make the DFU project will no this error,but show another error(we will talk about it in next blog):
