Description Robert Kuska 2015-08-18 08:04:08 EDT
unbound-libs creates dependency on python2 even though there seems to be no need for such a requires.

[fedora@localhost ~]$ rpm -q unbound-libs --requires | grep python

No file from unbound-libs doesn't seem to use python in any way. Linking to libpython is from libunbound.so.

[fedora@localhost ~]$ ldd /usr/lib64/libunbound.so.2 | grep python
	libpython2.7.so.1.0 => /lib64/libpython2.7.so.1.0 (0x00007fb8a7d18000)

From build.log:
libtool: link: gcc -I. -I/usr/include/python2.7 -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -fPIE -pie -flto -pthread -Wl,-z -Wl,relro -Wl,-z -Wl,now -pie -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -o .libs/unbound-host .libs/unbound-host.o .libs/keyraw.o .libs/sbuffer.o .libs/wire2str.o .libs/parse.o .libs/parseutil.o .libs/rrdef.o .libs/str2wire.o .libs/strlcat.o .libs/strlcpy.o  -L. -L.libs /builddir/build/BUILD/unbound-1.5.4/unbound-1.5.4_python2/.libs/libunbound.so -lssl -levent -ldl -lpython2.7 -lcrypto -pthread

My proposal is to package libunbound.so from python3 build of unbound.
Comment 1 Tomáš Hozza 2015-08-19 07:40:33 EDT
I think the libunbound.so should not be linked with python if not really necessary. I'll have to investigate if there is some good reason for that.
Comment 2 Tomáš Hozza 2015-09-03 07:55:12 EDT
There seems to be $LIBS variable in Makefile which includes '-lpythonX.Y' and is used everywhere. I'm investigating possible change.

In the meantime I reported this to upstream:
Comment 3 Tomáš Hozza 2015-09-03 14:12:28 EDT
Preferring Python3 build over Python2 for now. Leaving the ticket open.
