Build and install ecCodes C library for Windows (using MSYS2/MINGW64)
Install MSYS2

source: MSYS2

  • download installer for x86_64

  • install MSYS2 following the guide

  • uncomment MSYS=winsymlinks:nativestrict everywhere to enable symbol links

Install Mingw-w64 (run MSYS2 MinGW 64-bit shell)
pacman -S --needed base-devel git mingw-w64-x86_64-toolchain mingw-w64-x86_64-cmake
Install ecCodes dependencies (run MSYS2 MinGW 64-bit shell)
pacman -S mingw-w64-x86_64-zlib
curl -O http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-openjpeg2-2.1.2-2-any.pkg.tar.xz
pacman -U mingw-w64-x86_64-openjpeg2-2.1.2-2-any.pkg.tar.xz
pacman -S mingw-w64-x86_64-jasper
Build and install libaec

source: libaec

  • extract libaec-1.0.2.tar.gz to MSYS2 user home directory

  • replace original files by files from contrib\MSYS2\patches\libaec-1.0.2

  • run MSYS2 MinGW 64-bit shell and execute commands to build and install:

tar -xzf libaec-1.0.2.tar.gz
cd libaec-1.0.2
mkdir build
cd build
../configure
make check
make install
Build end install libeccodes

source: libeccodes

  • extract eccodes-2.5.0-Source.tar.gz to MSYS2 user home directory

  • replace original files by files from contrib\MSYS2\patches\eccodes-2.5.0-Source

  • run MSYS2 MinGW 64-bit shell and execute commands to build and install:

mkdir build
cd build
