1:30:47 yitzi drmeister: if you catchup llvm14 with main I can test it out tomorrow.

2:36:16 drmeister What llvm14 branches in repos.sexp?

3:02:53 drmeister bclasp is building using koga in the llvm14 branch.

11:38:49 yitzi Cando has a llvm14 branch, so that needs to be updared if you are building it

12:45:53 kpoeck ::notify drmeister: I have trouble with your latest changes to boehm_gc. Building in parallel fails with thread_suspend failed. This message seems to come from here: https://github.com/ivmai/bdwgc/blob/release-8_2/darwin_stop_world.c#L635. Did you have a chance to test the change on macos?

12:45:53 Colleen kpoeck: Got it. I'll let drmeister: know as soon as possible.

12:46:08 kpoeck build fine serially with -j1

12:51:00 drmeister Hello

12:54:58 drmeister kpoeck: Yeah - the new approach was working and I'm running into trouble as well. My errors are different from yours.

12:55:48 drmeister kpoeck: Are you building the llvm14 branch? I thought I hadn't touched the main branch.

12:55:56 kpoeck I wonder a bit about the configuration. Woudn't we need the result of platform specific configuration ?

12:56:02 kpoeck No, building main

12:56:10 kpoeck with llvm13

12:56:58 kpoeck in mygc.c you put like 4 values for boehm, is that really all needed?

12:58:20 drmeister Those are to configure the boehm code that I am including in mygc.cc

12:58:21 kpoeck I am tempted to copy all of my include/config.h there

12:58:26 drmeister mygc.c

12:58:54 drmeister Do you mean bdwgc/include/config.h

12:59:07 kpoeck but mygc,c does include  "extra/gc.c" which is all of bdwgc I thought

12:59:25 drmeister What do you think of this change? It appeared harmless and now you are running into a problem.

13:00:26 kpoeck I have a copy of bdwgc vs 8.2.0 on my mac. I thought i'd steal its include/config.h

13:00:44 drmeister I didn't read through every source file to get an idea of everything that is included. Let me do that first and then we can figure out what to put in mygc.c

13:00:52 kpoeck after building it, so it should have sound values

13:02:55 kpoeck Here are my values: https://gist.github.com/kpoeck/5666c63f951b1df974dba7f996abc24d

13:03:06 drmeister Now I'm getting a "thread_suspend failed" as well. I swear I didn't see that last night.

13:03:15 drmeister At least it's reproducing

13:03:24 kpoeck I did even restart my mac

13:06:05 drmeister I'm going to read through each of the files #include'd when I go `#include "extra/gc.c"` and each of the files #include'd by them and so on. Transitively. I'll build a list and then we will have a full list of what is included.

13:06:22 drmeister Huh - maybe I can get there faster by generating the preprocessed output of compiling mygc.c

13:06:58 kpoeck the error is from GC_stop_world

13:10:17 drmeister I should have been more careful before pushing it to main - I never seem to learn. (sigh).

13:11:20 drmeister I was so excited about it. The thing I liked about MPS was including it all within mygc.c - it gives us total control of the configuration and sort of removes a dependency of a properly configured and built library.

13:12:29 kpoeck Wild guess, don't we need #define HANDLE_FORK 1

13:14:31 kpoeck The configuration flags I have are: --disable-parallel-mark --enable-threads=pthreads --enable-large-config --enable-handle-fork=yes --enable-static=yes

13:15:30 drmeister kpoeck: We do need #define HANDLE_FORK 1 - we fork when we build clasp.

13:16:30 kpoeck Is it possible that it is not set now? Can't see it in mygc.c

13:16:35 drmeister kpoeck: Ok - you are exactly right. We need a full boehm config.h file. I'm a bit behind you in thinking...

13:17:03 drmeister ./configure in the bdwgc directory builds a config.h file and the way we are pulling it we don't get that.

13:17:38 drmeister Hmm, it isn't set.

13:17:39 kpoeck Do we even execute ./configure now?

13:17:45 drmeister Nope.

13:18:11 drmeister I think your original idea was great - pull a config.h file from building the library.
