Kerlink provides the cross-toolchain, libraries and headers necessary to the compilation of an application.

Retreive the installation package according to the linux build machine architecture available on the ressources page:

Unzip it and make it executable (example for 32 bits arch):

gunzip poky-glibc-x86_64-keros-cortexa9hf-vfp-neon-toolchain-1.8_c8115a9.sh.gz
chmod +x poky-glibc-x86_64-keros-cortexa9hf-vfp-neon-toolchain-1.8_c8115a9.sh

Execute the script:

./poky-glibc-x86_64-keros-cortexa9hf-vfp-neon-toolchain-1.8_c8115a9.sh
Enter target directory for SDK (default: /opt/poky/1.8): /opt/toolchains/loraV2
You are about to install the SDK to "/opt/toolchains/loraV2". Proceed[Y/n]? Y
Extracting SDK...done
Setting it up...done
SDK has been successfully set up and is ready to be used.

Modify toolchain environment file (use your own toolchain directory):

echo "unset CFLAGS" >> /opt/toolchains/loraV2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
echo "unset CXXFLAGS" >> /opt/toolchains/loraV2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
echo "unset LDFLAGS" >> /opt/toolchains/loraV2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

Source the toolchain environment :

source /opt/toolchains/loraV2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

System is ready to use “make”
