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.

launchpad.net/.../ download

but the How-to-build-toolchain.pdf only support ubuntu and Mac OS.

Hi,

There are prebuilt binaries available for Windows. From readme.txt:

Installing executables on Windows

Run the installer (gcc-arm-none-eabi-*-yyyymmdd-win32.exe) and follow the instructions.

Best regards,

Jørgen
