Installing the Go Chilkat Package on Linux
Prerequisites
The install script will first check to verify the following command are available on your Linux system: unzip, curl, sha256sum, and tar. If any of the commands are not available, the installChilkat.sh will exit with an error message prior to doing anything.
Installing
Run the following to download, build, and install. The install script (shown below) will download the required Chilkat native "C" library based on the CPU architecture, and also the Chilkat Go sources. It will validate the SHA256 checksums against the expected values. If all is OK, the downloads are extracted and the Chilkat Go module is built.
cd ~/temp curl https://chilkatdownload.com/10.0.0/build_chilkat_go.zip -o build_chilkat_go.zip unzip build_chilkat_go.zip cd build_on_linux chmod a+x *.sh ./installChilkat.sh ./buildExample1.sh ./buildExample2.sh
The installChilkat.sh script contains the following:
