[Ecls-list] Deadlock while compiling with threads (OpenBSD)

[Timo Myyrä]

Hi,

Now that OpenBSD has rthreads enabled ECL could be made to use them.
I tried to compile ECL with --enable-threads=yes but the compiling process seems
to cause deadlock in the code somewhere.

The compilation process completes compilation of C code but when it tries to
load the lisp files with minimal ecl it seems to deadlock on predlib.lsp.

Here's snippet of the part where it gets stuck:
head -8 config.log | tail -6 >> build-stamp
if [ -f CROSS-COMPILER ]; then  ./CROSS-COMPILER compile;  else  ECLDIR=`pwd`/ ./ecl_min compile;  fi
;*** Lisp core booted ****
ECL (Embeddable Common Lisp)

;;;
;;; Welcome to bare.lsp. Let's bring this instance up!
;;;
;;;
;;; About to load lsp/load.lsp
;;;
;;; Loading src:lsp;export.lsp
;;; Loading src:lsp;defmacro.lsp
;;; Loading src:lsp;helpfile.lsp
;;; Loading src:lsp;evalmacros.lsp
;;; Loading src:lsp;cmuutil.lsp
;;; Loading src:lsp;setf.lsp
;;; Loading src:lsp;predlib.lsp


While compiling the C sources I get following warnings, not sure if relevant but
I'll include those here:

Any suggestions what could cause the lock up and how to get threading working?

One quick fix to reduce warnings would be to include the newlines to the end of files on the
src/c/unicode/ directory.
