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 Jeff Bastian 2010-06-23 15:52:23 UTC 
Description of problem:
libtermcap has been replaced by ncurses (see bug 606588) in RHEL 6.0.  In order to provide compatibility with applications that were compiled on RHEL 5.x, the ncurses package should provide a libtermcap.so.2 symlink to libtinfo.so.5.

Version-Release number of selected component (if applicable):
ncurses-5.7-3.20090208.el6

How reproducible:
every time

Steps to Reproduce:
1. on a RHEL 5.x system:
     $ gcc -o termcap-demo termcap-demo.c -ltermcap
     $ ./termcap-demo 
     Your terminal is 80x48 characters
2. copy the termcap-demo binary to a RHEL 6.x system
     $ scp termcap-demo rhel6-system:/tmp
3. try to run the program on the RHEL 6.x system
     $ /tmp/termcap-demo 
     /tmp/termcap-demo: error while loading shared libraries: libtermcap.so.2:
     cannot open shared object file: No such file or directory
4. create a symlink to libtinfo.so.5 and try again
     $ sudo ln -s /lib64/libtinfo.so.5 /lib64/libtermcap.so.2
     $ /tmp/termcap-demo
     Your terminal is 80x48 characters

Actual results:
missing libtermcap.so.2 library prevents the program from running properly on a RHEL 6 system

Expected results:
RHEL 6 should allow applications compiled on RHEL 5 to work correctly

Comment 2 Miroslav Lichvar 2010-06-23 16:12:05 UTC 
The ABI provided by libtinfo is not 100% compatible with libtermpcap, so I'm not sure if creating the symlink is a good fix. It will probably work with most termcap applications, but some might fail.

Is this ok or do we need to resurrect libtermcap with termcap database in a compat package?
Comment 13 releng-rhel@redhat.com 2010-11-10 20:16:59 UTC 
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.

Unfortunately, compat-libtermcap-2.0.8-49.el6 does not create the links mentioned above.
