Try running /bin/bash ./configure ...  If that fails, your bash is likely too old (our minimum requirement is 3.x), so you will need to upgrade.  Alternatively, you can use our Makefile + user_settings.h instead of ./configure.  See our template in IDE/GCC-ARM (you can remove all of the ARM specific parts).

On Solaris, you will want to build wolfSSL as a static library using --enable-static --disable-shared, and ensure you are using gmake to build.  You may also need to disable our builtin make clean at the end of ./configure using --disable-makeclean.

Thanks,
Kareem
