[Caml-list] Test failure - why?

[Richard W.M. Jones]

This happened.  Is there a way to find out what went wrong?  There
seems to be no output saved anywhere ...

 ... testing 'debuggee.ml' with 1.1.1.1.1.1.1.1.1 (ocamldebug) => failed (Debugging program debuggee.exe: command /home/rjones/d/fedora/ocaml/master/ocaml-4.08.0+beta3/runtime/ocamlrun /home/rjones/d/fedora/ocaml/master/ocaml-4.08.0+beta3/debugger/ocamldebug -no-version -no-prompt -no-time -no-breakpoint-message -topdirs-path /home/rjones/d/fedora/ocaml/master/ocaml-4.08.0+beta3/toplevel debuggee.exe
failed with exit code 2)

Did you try to run the command manually to see what happens?

From the compiler distribution directory, going to

  testsuite/

and running

  make one DIR=tests/tools-toplevel

I observe various output (actually in the run I made I can see this failure
line as well). The test that fails in my case is find-artifacts/, so there
is a log directory

  tests/tool-debugger/find-artifacts/_ocamltest/

In particular there is a file

  cat
tests/tool-debugger/find-artifacts/_ocamltest/tests/tool-debugger/find-artifacts/debuggee/ocamlc.byte/debuggee.byte.output

which ends with

Debugger [version 4.10.0+dev0-2019-04-23] environment error:
 The files /usr/local/lib/ocaml/stdlib.cmi
 and
/home/gasche/Prog/ocaml/github-trunk/testsuite/tests/tool-debugger/find-artifacts/_ocamltest/tests/tool-debugger/find-artifacts/debuggee/ocamlc.byte/out/blah.cmi
 make inconsistent assumptions over interface Stdlib

This seems to be a problem where the testsuite environment is not
sufficiently isolated from the outside world, and another OCaml install
somewhere breaks things.

There's a bit more to this - when I run it from a straight git
checkout it (of course) doesn't fail.  It only fails when I build the
Fedora package.

However I did preserve the Fedora build root just now and was able to
run the command by hand there, and the error is:

  Fatal error: unknown C primitive `unix_fsync'

I suppose it must be linking to the wrong OCaml runtime - perhaps the
installed one (4.07.0)?

Hi Rich,

That error typically means that CAML_LD_LIBRARY_PATH is not correctly set.

Best wishes,
Nicolás

Just to keep you guys posted: at the moment I am not able to reproduce
the problem. We will see what we can do with the help of Gabriel.
