Hi,

With :
      --disable-hipe --disable-threads --disable-smp-support --without-javac

I've been able to build Erlang and to launch the tests by:  ct_run -suite ../compiler_test/andor_SUITE -case t_orelse

However, it fails at beginning: "Failed to start CTH", and it talks about a file "see the CT Log for details"" that I have no idea where it is.

I've only found at: otp_src_19.2/release/tests/test_server :
   .//tests.compiler_test.andor_SUITE.t_orelse.logs/run.2017-01-17_11.14.50/suite.log
but it does not help a lot

Any idea which document/file I should have a look at in order to understand the root cause of the failing testing ?
Any idea about the root cause of the failure ?


I've also tried with : erl -s ts install -s ts run all_tests -s init stop .

But it crashes:  init terminating in do_boot

Crash dump

Looking at: erl_crash.dump , I see:  Current Process CP: 0x00000000 (invalid)

erl_crash.dump file is attached to this email. REMOVED


I guess that I have to learn a little bit ( ;) ) more about how Erlang works.

See below for details.


Thanks

Tony

After building with Hipe, I've tried without Hipe.
And I got the same result: an infinite loop, in read() from
signal_dispatcher_thread_func().
  In: ERLC   ../ebin/hipe_rtl.beam              with Hipe (--enable-hipe)
  In: ERLC   ../ebin/hipe_consttab.beam   without Hipe (--disable-hipe)
. No idea why "hipe" appears here also.
So, for now, I have a common issue, with or without hipe.

I can provide some info regarding the behavior you are experiencing:

 - Certain modules of the 'hipe' application, though not all. are compiled independently of whether HiPE is enabled or not because they are used by 'dialyzer'.

 - It just so happens that 'hipe' is the first application that is compiled in the bootstrapping process, so the infinite loop you are getting is not related to HiPE but shows some deeper problem in the system you have built.

Bottomline: what you are experiencing is not HiPE-related.  Your system is broken.
