hi,everybody

Now I have set up wrapper/worker project successfully which generated work by hand using ./create_work according to the web page: http://boinc.berkeley.edu/trac/wiki/WrapperApp

However I shoud replace worker program with my own app, and sample_work_generator.C should be modified.And I have used ./make_project to make a skeletal project.

Here's the question: How to use the modified sample_work_generator.c to generate Daemon sample_work_generator

I bet you don't want to write your own Makefile.
backup the original sample_work_generator.C inside /$<boinc_source>/sched then modify sample_work_generator.C directly, then you run make inside that folder. There should be an executable file sample_work_generator there and copy that directly into the 'bin' folder under your project directory.
