Hi Ben,

I have tried building the synApps module with seq 2.2.0.1.  I am running into some problems that I could not figure out from the release notes:

../MAX_trajectoryScan.st: In function 'seqg_action_maxTrajectoryScan_0_execute':
../MAX_trajectoryScan.st:588:40: error: called object 'seqg_var->time' is not a function

The line with the error, which is in SNL code, not escaped C code, is:
			startTime = time(0);

This is the definition of startTime at the start of the SNL code.
/* Note, this should be time_t, but SNL doesn't understand that.  This is
 * the defininition in vxWorks. */
unsigned long startTime;  

The error occurs whether or not the following line is included at the top of the SNL code:
%% #include <time.h>

The next error is:

../MAX_trajectoryScan.st:996:3: error: too few arguments to function 'seq_pvGet'

The offending line is:

		seq_pvGet(ssId, pVar->epicsMotorDoneIndex[j], 0);

This is in escaped C code at the end of the file.  The program is built with the "+r" option.

The final error is:

/corvette/home/epics/devel/seq-2-2-0-1/bin/linux-x86/snc     getFilledBuckets.i -o getFilledBuckets.c
../getFilledBuckets.st:151: error: calling built-in function delay not allowed here

Line 151 is the delay(1.0) statement in the code below:

			when((srInjectStatus ==  NOTINJECTING) &&
				(srBeamStatus) == STOREDBEAM) {
				delay(1.0);  /* 1 sec delay */

Is this error due to this change in 2.2.0:

"Since calling delay outside of the condition of a state transition never had any useful effect, it is now disallowed."

Thanks,
Mark

Hi Everyone

I am happy to (finally!) anounce the first public release of the EPICS
Sequencer version 2.2. This release contains many new features, see the
release notes [0] for details. There are also some changes to the
interface between compiler and run-time system, which may cause trouble
when trying to build existing programs, especially ones that heavily
rely on escape to C. I tried to keep the incompatibilities to a minimum,
though, so most programs should build fine with the new version. Details
about this are also in the release notes.

Building on Windows might fail because unfortunately I could not test
that yet.

Please report any problems you notice. I will go on holidays from
Thursday until the end of August, and I will probably not be able to
answer questions during this time, but I promise I'll address all of
them when I come back.

Cheers
Ben
