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 Michael Peters 2018-12-07 05:42:06 UTC 
Description of problem:
FT_ENCODING_PRC not defined

Version-Release number of selected component (if applicable):
freetype-2.8-12.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. Try to build something that asks for ft_encoding_gb2312
2. The freetype.h header for backwards compatibility defines that as FT_ENCODING_PRC
3. Build fails because FT_ENCODING_PRC isn't defined

Actual results:
Build fails


Expected results:
In previous freetype, ft_encoding_gb2312 is defined as FT_ENCODING_GB2312 which is defined in both.


Additional info:
freetype 2.4.11-15.el7 package:

grep -c "FT_ENCODING_PRC" freetype.h 
0
grep "FT_ENCODING_GB2312" freetype.h
  /*    FT_ENCODING_GB2312 ::                                              */
  /*      Same as FT_ENCODING_GB2312.  Deprecated.                         */
    FT_ENC_TAG( FT_ENCODING_GB2312,  'g', 'b', ' ', ' ' ),
    FT_ENCODING_MS_GB2312  = FT_ENCODING_GB2312,
#define ft_encoding_gb2312          FT_ENCODING_GB2312

But with freetype 2.8-12.el7:

grep "FT_ENCODING_PRC" freetype.h 
  /*    FT_ENCODING_PRC ::                                                 */
  /*      Same as FT_ENCODING_PRC.  Deprecated.                            */
#define ft_encoding_gb2312          FT_ENCODING_PRC

grep "FT_ENCODING_GB2312" freetype.h 
    FT_ENC_TAG( FT_ENCODING_GB2312,  'g', 'b', ' ', ' ' ),
    FT_ENCODING_MS_GB2312  = FT_ENCODING_GB2312,

It appears that a change in taking place renaming FT_ENCODING_GB2312 to FT_ENCODING_PRC but that the header only partially reflects that change ???

It breaks the build of modern ImageMagick that built fine in CentOS (and presumably RHEL) 7.5
