Taking the linyaps project org.deepin.demo, as an example, the main steps to build a linyaps application would be as follows:
Go to the org.deepin.demo project directory:
cd org.deepin.demoExecute the ll-builder build command to start building:
ll-builder buildAfter the build is complete, the build content will be automatically committed to the local ostree cache. See ll-builder export for exporting build content.
Use the --exec parameter to enter the linyaps container before the build script is executed:
ll-builder build --exec /bin/bashAfter entering the container, you can execute shell commands, such as gdb, strace, etc.
