Description Richard W.M. Jones 2014-08-27 14:21:10 UTC
+++ 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

    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.

Comment 3 dyuan 2015-01-19 10:09:59 UTC
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.

Comment 4 Richard W.M. Jones 2015-01-19 14:27:36 UTC
(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.

Comment 5 dyuan 2015-01-20 03:02:32 UTC
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
