Lots of error in make showing struct rt_task’ has no member named ‘XXX‘

[songzeceng]

I tried to compile pgm with litmusRT(linux-4.9-litmus)，but I got lots of errors as following:

I cannot find member named split in the source code of litmusRT of branch linux-4.9-litmus or master-before-2013.1or master-before-2014.2...

Besides nothrow in the code below is of no use with build error, so I comment it out.

 // pgm.cpp line 1637
 gGraphs = new (nothrow) struct pgm_graph[PGM_MAX_GRAPHS];

struct rt_task is defined by Litmus in include/litmus/rt_param.h. I can't recall what the split field was for. I can't find it it in any of the versions of Litmus that I have. What happens if you simply comment it out?

[songzeceng]

Thanks for help.I comment out every nonexist rt_task field used in tools/pgmrt.cpp，but I still got some new errors as below showing undefined fields in some macro definition

I see the related codes in tools/pgmrt as following and macros like litmus_pgm_wait are used somwhere else in this file. So I don`t know how to handle it

#ifdef _USE_LITMUS
// waiting task's priority is boosted as needed
#define litmus_pgm_wait(statements) \
	enter_pgm_wait(); \
	statements \
	exit_pgm_wait();
// signalling task's priority is unconditionally boosted,
// so just enter a non-preemptive section.
#define litmus_pgm_complete(statements) \
	enter_pgm_send(); \
	statements \
	exit_pgm_send();

[songzeceng]

I solved it by comment all the codes related to such macros. They are

// litmus_pgm_complete(CheckError(pgm_complete(cfg.node)););

and

// litmus_pgm_wait(ret = pgm_wait(cfg.node););

with macro definition

/*#define litmus_pgm_wait(statements) \
	enter_pgm_wait(); \
	statements \
	exit_pgm_wait();*/
// signalling task's priority is unconditionally boosted,
// so just enter a non-preemptive section.
/*#define litmus_pgm_complete(statements) \
	enter_pgm_send(); \
	statements \
	exit_pgm_send();*/

I am worried the impact on the functionality but at least I get my compliation passed.
Maybe you should update the source code of pgm
