Description pva 2009-02-12 06:54:14 UTC
I have net-misc/mDNSResponder installed but during configure phase I still have the following error:

checking for dns_sd.h... yes
checking for DNSServiceRegister... no
checking for DNSServiceRegister in -ldns_sd... yes
configure: error: DNS service discovery support not available

If you check ./configure script you'll find that there is no ac_cv_lib_ext_DNSServiceRegister variable anywhere there. This sed script fixes the issue for me:

sed -e 's|ac_cv_lib_ext_DNSServiceRegister|ac_cv_lib_ext_dns_sd_DNSServiceRegister|' \
 -i source/configure

Thank you for your work on samba!

This sed script is not enough. Later I see the following error:

The following patch fixes that:

This one has already been fixed meanwhile with commit 16f072809 from Björn Jacke in the master branch. It will be included in 3.3.1.

Thank you very much for reporting and providing the patch!
