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.

+++ This bug was initially created as a clone of Bug #1134453 +++

Description of problem:

$ pkg-config --libs libvirt
-lvirt -ldl -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic 

obviously only -lvirt and possibly -ldl should be there.

Version-Release number of selected component (if applicable):

On RHEL 7: libvirt-1.1.1-29.el7.x86_64

commit 1167751fcb949b44eddf3d0bfed5473e13c7e94a

    Don't include @LIBS@ in libvirt.pc.in file
    
    The libvirt.pc file we install is ending up polluted with a
    load of compiler flags that should be private to the libvirt
    build. eg
    
    Libs: -L${libdir} -lvirt -ldl -O2 -g -pipe -Wall \
          -Wp,-D_FORTIFY_SOURCE=2 -fexceptions \
          -fstack-protector-strong --param=ssp-buffer-size=4 \
          -grecord-gcc-switches  -m64 -mtune=generic
    
    this is caused by including @LIBS@ in the Libs: line of the
    pkgconfig.pc.in file.

Install libvirt-1.2.8-13.el7.src.rpm.

# grep lvirt /root/rpmbuild/BUILD/libvirt-1.2.8/build/libvirt.pc
Libs: -L${libdir} -lvirt

# pkg-config --libs libvirt
-L/root/builder/lib -lvirt

Removed the @LIBS@ in the Libs and only -lvirt is here, move the bug to VERIFIED.

(In reply to dyuan from comment #3)
> # pkg-config --libs libvirt
> -L/root/builder/lib -lvirt

That's not good!

The output should be:

$ pkg-config --libs libvirt
-lvirt  

Having said that, I am unable to reproduce the output
you have given above.  For me, the output is correct
with the 1.2.8-13.el7 package.

Yes, you're right. Thanks for your comment.
I think there should be copy/paste error in comment3.
Re-check again and got the same output as yours.

# pkg-config --libs libvirt
-lvirt
