So, ECL starts up without problems now, but there is an (apparently) known issue with GC. The app crashes, seemingly during the first cycle of GC, see attached backtrace.
But I noticed these lines in the 'ecl-android' project (github) of old, which has also an 'iOS' directory with an example app. There you find these lines before 'cl_boot':
int argc = 1; char *argv[256]; argv[0] = "ecl"; GC_allow_register_threads(); GC_register_my_thread((const struct GC_stack_base *)argv); GC_stackbottom = (char*)(argv+255); // corrected to 'char*' (was: 'void*') setenv("ECLDIR", "", 1); cl_boot(argc, argv);
Now, if I put the above lines before 'cl_boot', the app works.
Does anybody know why this is needed, and what it is doing? Because if my Lisp app grows (I tried to include :cl-ppcre), then the app crashes again, despite the above hack (and with the same backtrace of the attachment).
Of course I already tried bigger vector sizes (up to 8192) instead of 256, but that doesn't solve it.
What else could I try?
Thanks,
Paul
