Hello,
I have the following issue on macOS with latest git:
I'm compiling ecl with:
ABI=32 CFLAGS="-m32" LDFLAGS="-m32" ./configure --prefix=/opt/ecl/tmp
--enable-threads=yes
This test fails about 50% of the time:
(defun safe-system (string)
;; (cmpnote "Invoking external command:~% ~A~%" string)
(let ((result (ext:system string)))
(unless (zerop result)
(cerror "Continues anyway."
"(SYSTEM ~S) returned non-zero value ~D"
string result))
result))
(safe-system "sh -c 'echo OK'")
(si:quit 0)
$ /opt/ecl/tmp/bin/ecl -load test.lsp
;;; Loading "/Users/sylvain/src/lisp/ecl/test.lsp"
OK
$ /opt/ecl/tmp/bin/ecl -load test.lsp
;;; Loading "/Users/sylvain/src/lisp/ecl/test.lsp"
OK
An error occurred during initialization:
(SYSTEM "sh -c 'echo OK'") returned non-zero value -1.
$ /opt/ecl/tmp/bin/ecl -load test.lsp
;;; Loading "/Users/sylvain/src/lisp/ecl/test.lsp"
OK
* The call to "system" is failing with ECHILD (The calling process has no
existing unwaited-for child processes).
* I could pinpoint it to commit a7000ca0f9f360fc1e0697b1c879096aa189e10e
(Reimplementation of the SIGCHILD handler).
* It doesn't happen when compiling 64 bits or compiling with threads disabled
Unrelated to this, the following patch should fix an issue that "ar" is called
in some build steps instead of $(AR). This can cause some problems when
cross-compiling:
