Corentin ping?

[Comment 5 LABBE Corentin 2013-12-23 09:19:05 UTC]

The problem was detected by the configure:
checking for headers required to compile python extensions...   File "<string>", line 1
    import sys; print sys.prefix
                        ^
SyntaxError: invalid syntax
  File "<string>", line 1
    import sys; print sys.exec_prefix
                        ^
SyntaxError: invalid syntax
not found

Does this still happen with recent version of openscap ?

This issue was opened against what was and still is the most recent version,  app-forensics/openscap-0.9.12.  Updating the file attachments with the most recent attempt.

Do you have multiple Pythons installed?

If so, care to switch to Python 2.<something>? The syntax shown is not valid for Python 3, so we might need to mark it for Python-2 only (or fix it ourselves, but that might be a *very* *deep* rabbithole ;)

Switching to python2.7 from my current default of python3.3 did the trick.  As that is apparently a strict dependency, openscap should require it, or look for an installed instance of 2.7 and actually use it, don't you think?  Relying on system default when python 2.7 is readily available seems, well, unreliable.

[Comment 13 Sven Vermeulen (RETIRED) 2013-12-23 20:05:08 UTC]

True. The ebuilds already mention this, but it hasn't been implemented further in the src_* functions I guess...

"""
PYTHON_DEPEND="2"
PYTHON_COMPAT=( python{2_5,2_6,2_7} )
"""

Seems like adding "python_setup" at the beginning of the src_configure() phase does the trick. If anyone else can confirm this, I'll gladly commit it.

Works for me.  `emerge app-forensics/openscap` with python3.3 set as system default completed successfully.

Looks like openscap-1.0.1.ebuild was released to us without integrating this patch, or for that matter without openscap-0.9.12.ebuild being updated.  Should I open a new ticket for openscap-1.0.1 or is this one sufficient?

[Comment 17 Sven Vermeulen (RETIRED) 2013-12-26 16:48:25 UTC]

The confirmation was still pending; no need for a new bugreport, I'll update the ebuilds accordingly.

[Comment 18 Sven Vermeulen (RETIRED) 2013-12-26 16:53:09 UTC]

There ya go, fix implemented for 0.9.12, 1.0.1 and 9999.
