Re: [scl.org] Question about generating RPMs that depend on SCLs (like python27)





Requires:       %{scl_prefix_python}-scldevel
                                                  ^^^^^^
I think you are missing the "-"
Nope, %{scl_prefix_python} should expand to "python27-", e.g. if defined, it should already contain the "-". Alan, where are your packages coming from? We added the -scldevel packages to RHSCL 1.1 downstream and I can also see one on scl.org [1]. Are you using older builds of python27 SCL, perhaps from RHSCL 1.0?

Similar issue with this line:
Requires:       %{scl_prefix_python}scldevel

There is no scldevel package, nor a python27-scldevel

So, I'm trying to take the page you pointed at seriously - so I added this line from that page:
BuildRequires: scl-utils-build

There is no such package.  What was intended here?

OK.  It was pointed out to me off-list that I was comparing the wrong thing.
I should have been looking at python27-python.  Here's what that package shows:

bash-4.1# *rpm -q --provides python27-python*
python27-python-abi = 2.7
python27-python(abi) = 2.7
python27-Distutils
python27-python2 = 2.7.5
python27-python-sqlite = 2.3.2
python27-python-ctypes = 1.0.1
python27-python-hashlib = 20081120
python27-python-uuid = 1.31
python27-python-argparse = 2.7.5-7.el6.centos.alt
python27-python = 2.7.5-7.el6.centos.alt
python27-python(x86-64) = 2.7.5-7.el6.centos.alt
bash-4.1#

Either I'm failing to do something to appease the automagical python-version
detection (which I have no idea how it figures that out), or the property
names in python27-python should not have the "python27-" prefix.

Anyone know which it is - and how to deal with it?

It seems to me like the attributes of the provides should not be prefixed by
python27.  But I'm new to this SCL stuff...

FWIW - they "python(abi) = ##" requires is added by /usr/lib/rpm/pythondeps.sh
as part of the standard rpm dependency generation.  So yes, for this to work
with the scl, either the scl needs to provide "python(abi) = 2.7" or you will
need to disable the automatic requires generation or filter out the
python(abi) line.

We're all new to this SCL stuff.... :)



Here's the magic from https://access.redhat.com/documentation/en-US/Red_Hat_Developer_Toolset/2/html/Software_Collections_Guide/sect-Extending_the_python27_and_python33_Software_Collections.html


# Similarly, override __python_requires for automatic dependency generator
%global __python_requires %{%{scl_python}_python_requires}
