Bug 242332

Summary: net/vde2: missing shared library if net/libpcap is installed during build but removed afterwards

Description Ting-Wei Lan 2019-12-01 04:01:29 UTC 
The Makefile of net/vde2 includes this line:

LIB_DEPENDS=	libpcap.so:net/libpcap

Since libpcap.so exists in base, it does not pull in any dependency:

===>   vde2-2.3.2_4 depends on shared library: libpcap.so - found (/usr/lib/libpcap.so)

However, vde2 seems to prefer libpcap from ports to the one in base. If libpcap from ports is present in the build environment, vde2 links to it but the dependency isn't registered into pkg. Therefore, it is possible for users to type 'pkg autoremove' to remove libpcap and cause 'pkg check' to show:

vde2 is missing a required shared library: libpcap.so.1

Any proposed patch? Perhaps specify rpath?
Comment 2 Dmitry Marakasov freebsd_committer freebsd_triage 2021-02-19 22:53:25 UTC 
Should be fixed by explicitly specifying required shlib version, e.g. LIB_DEPENDS=    libpcap.so.1:net/libpcap

grep libpcap.so in build.log before the change:

===>   vde2-2.3.2_5 depends on shared library: libpcap.so - found (/usr/lib/libpcap.so)
===>   vde2-2.3.2_5 depends on shared library: libpcap.so - found (/usr/lib/libpcap.so)
actual-package-depends: dependency on /usr/lib/libpcap.so not registered (normal if it belongs to base)
actual-package-depends: dependency on /usr/lib/libpcap.so not registered (normal if it belongs to base)
 0x0000000000000001 NEEDED               Shared library: [libpcap.so.8]

After the change:

===>   vde2-2.3.2_5 depends on shared library: libpcap.so.1 - not found
===>   vde2-2.3.2_5 depends on shared library: libpcap.so.1 - found (/usr/local/lib/libpcap.so.1)
===>   vde2-2.3.2_5 depends on shared library: libpcap.so.1 - found (/usr/local/lib/libpcap.so.1)
 0x0000000000000001 NEEDED               Shared library: [libpcap.so.1]
