RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Karel Srot 2016-04-05 07:17:29 UTC
According to my testing the bug is present also on RHEL-6, tested with
rpm-4.8.0-55.el6 and rpm-4.8.0-37.el6.

+++ This bug was initially created as a clone of Bug #1246746 +++

Description of problem:
Recursively and conditionally defined macro behave differently in RHEL-6 (4.8) and RHEL-7 (4.11).
Fedora (version 4.12) behaves like RHEL-6, which seems correct)

Version-Release number of selected component (if applicable):
  rpm-build-4.11.1-25.el7

How reproducible:
  Always

Steps to Reproduce:
  Use in the spec 

  %if "%{?scl}" == "rh-php56"
  %global sub_prefix more-php56-
  %else
  %global sub_prefix %{?scl_prefix}
  %endif

  Name: %{?sub_prefix}php-pecl-%{pecl_name}

During SCL build, and %SCL = "php56"

Actual results:
  RHEL-6 and Fedora 21+
  Name is php56-php-pecl-name (correct)

  RHEL-7
  Name is php-pecl-name  (missing prefix)


Expected results:
  Name always php56-php-pecl-name


Additional info:
Example spec file : https://raw.githubusercontent.com/remicollet/remirepo/master/php/pecl/php-pecl-apfd/php-pecl-apfd.spec

Workaround: less conditionally defined macro (used in previous spec)
  %if 0%{?scl:1}
  %if "%{scl}" == "rh-php56"
  %global sub_prefix more-php56-
  %else
  %global sub_prefix %{scl_prefix}
  %endif
  %endif
