I'm not quite sure what the difference is (I have gcc 4.8, but there are
probably also header differences), but when I compile the service on 14.04 I
get:
CC cr-service.o
cr-service.c: In function ‘start_page_server_req’:
cr-service.c:536:8: error: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Werror=unused-result]
write(start_pipe[1], &ret, sizeof(ret));
^
cr-service.c:544:6: error: ignoring return value of ‘read’, declared with attribute warn_unused_result [-Werror=unused-result]
read(start_pipe[0], &ret, sizeof(ret));

criu ==== An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space. The project home is at http://criu.org Pages worth starting with are * Kernel configuration, compilation, etc: http://criu.org/Installation * A simple example of usage: http://criu.org/Simple_loop * More sophisticated example with graphical app: http://criu.org/VNC
