Oil Enquiry: REL_DEADLINE

[yasserfathy]

Hello and thanks for your services,

I would like to ask a question concerning RT-Druid and the oil language, I'm trying to compile a project that uses erika os, a linking error was produced stating that the variable 'EE_th_absdline' is undefined, the following are the ways 'EE_th_absdline' is used in the code:

EE_th_absdline[t] = EE_hal_gettime()+EE_th_reldline[t];

and

if (t == EE_NIL || // this test works also for the main task
(EE_stk_queryfirst() != EE_NIL &&
((EE_STIME)(EE_th_absdline[EE_stk_queryfirst()] - EE_th_absdline[t]) <= 0
|| EE_sys_ceiling >= EE_th_ready_prio[t])))

so I assumed that this array should be generated by RT-Druid from the oil file, and that it should contain the absolute deadlines for all threads.

so I checked the thread definition in the oil file and found that it contains a variable called "REL_DEADLINE" that is filled with type "string".

the problem is that I don't know how to set this variable and it isn't mentioned in the oil 2.5 documentation, and when I set it with random strings, nothing changes in the eecfg.c, eecfg.h files.

Hope you can refer me to the documentation where this variable is described so that the 'EE_th_absdline' array definition would be produced.

Thanks.

That is part of the EDF kernel, just check the examples on EDF for the dsPIC... they should work.

thanks paolo for your help,

but the linker produces errors in the semaphore files ee_spost.c, ee_swait.c , in both cases the compiler options are as follows
/***********************************************/
#if defined(__FP__)

some code

#else

the code that uses EE_th_absdline

#endif

/***********************************************/

and it isn't a part of EDF code, or is there a problem in the source code?
