Bug 510206 – net-libs/ldns: ldns-config --libs outputs -lpython*

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Michał Górny 2014-05-13 06:18:27 UTC]

$ ldns-config  --libs
-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu  -L/usr/lib64 -lpython2.7 -L/usr/lib64   -lcrypto -ldl -lldns

I feel like -lpython2.7 got there unnecessarily, esp. that shared libldns doesn't link to it.

This seems to be dependent on the python USE flag, with this version and uses this issue doesn't happen:
# equery u ldns
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for net-libs/ldns-1.6.17:
 U I
 + + abi_x86_32                     : 32-bit (x86) libraries
 + + dane                           : Enable DNS-based Authentication of Named Entities (DANE) support
 - - doc                            : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally

Looks like this is not an issue anymore:

 # ldns-config --libs
-Wl,-O1 -Wl,--as-needed  -L/usr/lib64  -lssl  -lcrypto -lldns
