Aha! I got it to build. In Termux, which currently uses clang-16: After running ./configure, 1. Add -std=gnu++11, rather than c++11, to src/Makefile and src/emacs_mode/Makefile CXXFLAGS; 2. Add #include <pthread.h> to src/Thread_context.cc and change the call near line 49 from pthread_cancel(thread) to pthread_kill(thread, 0)
In regards to pthread_cancel() ... I hope the following is not true: Termux (or Android beneath it) uses 'bionic libc' that does not implement pthread_cancel according to https://github.com/termux/termux-app/discussions/2639 Some discussion about emulating it or replacing with pthread_kill(thread, 0) here: https://github.com/axel-download-accelerator/axel/issues/150 I don't know who or what to test to see what deleterious effects, if any, using pthread_kill() instead of pthread_cancel() will have on operation. However, the main prompt comes up and I can run basic APL expressions. -Russ On Mon, Oct 2, 2023 at 6:44 PM Callahan, Brian Robert <call...@rpi.edu> wrote: > Hi Russ – > > > > On OpenBSD, clang has been the default compiler for many years.
