If you set your default workspace to 'build on startup' then you won't need to recompile every time. In CodeBuilder, right-click on the Origin C Workspace root folder and select 'Build on Startup'.
Thanks Laurie! I guess recompiling it only at routine call with err = run.LoadOC("myWorkspace.ocw",[option = 2]); would be more specific, at our wish and not at every Origin session. Besides our "myWorkspece.ocw" would not be built if it was not the currently loaded at Origin startup. Best Regards,
