Description Dan Horák 2016-09-12 13:32:56 UTC

Description of problem:
Although supermin builds fine on s390x with the interpreted Ocaml, it doesn't seem to work correctly. I've found it when building libguests that failed with

...
checking if we should build the appliance... yes
checking for supermin... /usr/bin/supermin
checking for --with-supermin-packager-config option... not set
checking for --with-supermin-extra-options option... not set
checking supermin is new enough... configure: error: supermin >= 5.1 must be installed, your version is too old
error: Bad exit status from /var/tmp/rpm-tmp.VHAmuM (%build)

with

in config.log

Version-Release number of selected component (if applicable):
supermin-5.1.16-4.fc25

How reproducible:
100%

Steps to Reproduce:
1. supermin --version

Actual results:
[sharkcz@devel11 ~]$ supermin --version
Unknown option --version.

Expected results:
[dan@eagle ~]$ supermin --version
supermin 5.1.16

Additional information:
Looks to me as it install only a wrapper, but no actual supermin binary, because

[sharkcz@devel11 ~]$ supermin
No bytecode file specified.

while on x86_64 I see

[dan@eagle ~]$ supermin
supermin: you must use --prepare or --build to select the mode

Comment 1 Richard W.M. Jones 2016-09-12 13:50:40 UTC

"No bytecode file specified." happens because running strip on
bytecode files damages them.

To avoid this we usually disable stripping in the RPM:

  %ifnarch %{ocaml_native_compiler}
  %global __strip /bin/true
  %endif

Comment 2 Richard W.M. Jones 2016-09-12 13:52:19 UTC

BTW there is rumoured to be an s390x backend for the OCaml compiler,
although I have not used it and it's not in our OCaml package.

looks like
%global debug_package %{nil}
is also required for supermin to work ...

Comment 4 Richard W.M. Jones 2016-09-15 09:48:42 UTC

Quite likely.  Please make sure that statement is conditional
on %{ocaml_native_compiler} too.

Comment 5 Dan Horák 2016-09-15 10:54:41 UTC

another solution - use dietlibc and no workarounds are needed
