15:42:07 drmeister Hello.

15:42:26 drmeister I survived... anyone else?

15:43:29 frgo Hello. You got over your cold that fast? Impressive.

15:44:02 drmeister I worked through the first couple of days of it - yesterday was bad.

15:44:35 drmeister It looks like I fixed block/return-from for bclasp.

15:45:00 frgo Yeah - read that. Very nice. So on to ... what?

15:45:05 drmeister It's amazing that I could get something fundamental like that so wrong (using a runtime stack) that still worked 99.999999% of the time.

15:45:14 Bike fixing all the other problems, of course

15:45:37 Bike well returning from an inner function is fairly rare to start with, let alone those twisty scenarios

15:45:57 drmeister On to getting fixing tagbody/go the same way and getting CST's incorporated.

15:48:02 drmeister In block/return-from where the return-from is in a nested function the block has to close over some unique value that the return-from has access to so that the stack can be unwound properly.

15:52:38 frgo And how did you solve the unique value challenge?

16:20:45 drmeister I allocate a CONS cell.

17:27:19 frgo drmeister: Please see: https://github.com/dg1sbg/clasp/tree/ext-rti-dds/extensions/rti-dds - is that ok for you re publishing / communication about this extension?

18:33:05 frgo drmeister: Q: Why don't I see -D flags defines with cfg.define() when the scraper runs? - How do I add to DEFINES as in https://github.com/dg1sbg/clasp/blob/dev/wscript#L1387 ? Thx for having a look at this ...

18:51:10 drmeister Hi -

18:52:17 drmeister frgo: Yes - publishing/communicating about your extension is fine.

18:53:21 drmeister frgo: For defines I add things like this...

18:53:55 drmeister https://github.com/drmeister/clasp/blob/cst/wscript#L650

18:54:18 drmeister Then in the C++ code I can go #ifdef PROGRAM_CLASP ... #endif

18:54:51 drmeister They don't get added as -D command line options. They get added to a header file by waf and that gets included in the source code.

20:05:00 frgo drmeister: Thx. I need to have defines active when the scraper runs. I assume I need to add to "DEFINES" as then used in https://github.com/dg1sbg/clasp/blob/dev/wscript#L1387 - do you happen to know how to do this?

20:05:56 frgo Or should I simply add stuff to CXXFLAGS (will do that as a plan b)?

20:07:25 drmeister Add them in your extension wscript file like this...

20:07:26 drmeister https://github.com/drmeister/cando/blob/dev/wscript#L8

20:07:52 drmeister https://github.com/drmeister/cando/blob/dev/wscript#L12

20:08:00 drmeister You can also add additional libraries here.

20:08:21 drmeister These will be defined when the scraper runs.

20:10:14 frgo Yeah - thx.
