Two subjects, first the download page for unbound-1.4.9.tar.gz gives : 404 Not Found. The latest link works. second, Im trying to compile unbound-1.4.9 on Solaris 11 express x64 with Solaris Studio 12.2 A simple ./configure gives: # ./configure checking build system type... i386-pc-solaris2.11 checking host system type... i386-pc-solaris2.11 checking target system type... i386-pc-solaris2.11 checking for gcc... no checking for cc... cc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... no checking whether cc accepts -g... yes checking for cc option to accept ISO C89... none needed checking how to run the C preprocessor... cc -E checking for grep that handles long lines and -e... /usr/bin/ggrep checking for egrep... /usr/bin/ggrep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking minix/config.h usability... no checking minix/config.h presence... no checking for minix/config.h... no checking whether it is safe to define __EXTENSIONS__... yes checking for an ANSI C-conforming const... yes checking whether cc supports -g... yes checking whether cc supports -O2... yes checking whether we are using the GNU C compiler...
