AX_PTHREAD requires _REENTRANT to confirm that pthread support is enabled. Solaris 11.4 headers no longer use the macro, and GCC 16 therefore no longer defines it for -pthread. Detect XPG7 support in the target headers and require _REENTRANT only on older Solaris releases. The existing pthread compile and link test remains the final capability check. This follows the canonical Autoconf Archive change: https://github.com/autoconf-archive/autoconf-archive/pull/341 Regenerate configure with Autoconf 2.71. Tested on Solaris 11.4 with GCC 15.2 and GCC 16.1. The Autoconf Archive change was also tested on Solaris 11.3. Co-authored-by: Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE>
Unbound
Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards. If you have any feedback, we would love to hear from you. Don’t hesitate to create an issue on Github or post a message on our community forum. You can learn more about Unbound by reading our documentation.
Compiling
Make sure you have the C toolchain, OpenSSL and its include files, and libexpat installed. If building from the repository source you also need flex and bison installed. Unbound can be compiled and installed using:
./configure && make && make install
You can use libevent if you want. libevent is useful when using many (e.g.,
10000) outgoing ports.
Use the --with-libevent configure option to compile Unbound with libevent
support.
If not, the default builtin alternative opens max 256 ports at the same time and is equally capable and a little faster.
Unbound configuration
All of Unbound's configuration options are described in the unbound.conf(5)
man page, which will be installed and is also available on the Unbound
documentation page
for the latest version.
An example configuration file, with minimal documentation, is located in doc/example.conf.
