-To compile libjunbound

-

-Linux (libunbound, libldns and lcrypto shared):

-----------------------------------------------

-a) With autoconf

-autoreconf --install

-./configure

-make

-cp ./libs/libjunbound.so ../../lib/native/linux

-

-b) With manual makefile

-make -f makefile.linux

-

-Linux (libunbound statically linked, lcrypto shared):

-----------------------------------------------------

-Use make-linux.sh

-

-Mac:

----

-Use make-mac.sh

-

-Windows:

--------

-- Get ldns, libexpat, unbound and compile them

-- make -f makefile.w32

-

-Expat Win64:

-./configure --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32

-

-Unbound Win64:

-The configure script wrongly detects getaddrinfo as Unix. Break the detection

-script at line 16085 (1.4.12)

-

-OpenSSL Win64:

-configure mingw64 -no-capieng -no-asm

-make

-make check (http://stackoverflow.com/questions/7256087/error-compiling-openssl-with-mingw-msys)

-mkdir lib

-cp libcrypto.a lib

-cp libssl.a lib

-/**
- * \file
- *
- * This file contains functions to resolve DNS queries and 
- * validate the answers. Synchonously and asynchronously.
- *
- * Several ways to use this interface from an application wishing
- * to perform (validated) DNS lookups.
- *
- * All start with
- *	ctx = ub_ctx_create();
- *	err = ub_ctx_add_ta(ctx, "...");
- *	err = ub_ctx_add_ta(ctx, "...");
- *	... some lookups
- *	... call ub_ctx_delete(ctx); when you want to stop.
- *
- * Application not threaded. Blocking.
- *	int err = ub_resolve(ctx, "www.example.com", ...
- *	if(err) fprintf(stderr, "lookup error: %s\n", ub_strerror(err));
- *	... use the answer
- *
- * Application not threaded. Non-blocking ('asynchronous').
- *      err = ub_resolve_async(ctx, "www.example.com", ... my_callback);
- *	... application resumes processing ...
- *	... and when either ub_poll(ctx) is true
- *	... or when the file descriptor ub_fd(ctx) is readable,
- *	... or whenever, the app calls ...
- *	ub_process(ctx);
- *	... if no result is ready, the app resumes processing above,
- *	... or process() calls my_callback() with results.
- *
- *      ... if the application has nothing more to do, wait for answer
- *      ub_wait(ctx); 
- *
- * Application threaded. Blocking.
- *	Blocking, same as above. The current thread does the work.
- *	Multiple threads can use the *same context*, each does work and uses
- *	shared cache data from the context.
- *
- * Application threaded. Non-blocking ('asynchronous').
- *	... setup threaded-asynchronous config option
- *	err = ub_ctx_async(ctx, 1);
- *	... same as async for non-threaded
- *	... the callbacks are called in the thread that calls process(ctx)
- *
- * If no threading is compiled in, the above async example uses fork(2) to
- * create a process to perform the work. The forked process exits when the 
- * calling process exits, or ctx_delete() is called.
- * Otherwise, for asynchronous with threading, a worker thread is created.
- *
- * The blocking calls use shared ctx-cache when threaded. Thus
- * ub_resolve() and ub_resolve_async() && ub_wait() are
- * not the same. The first makes the current thread do the work, setting
- * up buffers, etc, to perform the work (but using shared cache data).
- * The second calls another worker thread (or process) to perform the work.
- * And no buffers need to be set up, but a context-switch happens.

-/**
- * \file
- *
- * This file contains functions to resolve DNS queries and 
- * validate the answers. Synchonously and asynchronously.
- *
- * Several ways to use this interface from an application wishing
- * to perform (validated) DNS lookups.
- *
- * All start with
- *	ctx = ub_ctx_create();
- *	err = ub_ctx_add_ta(ctx, "...");
- *	err = ub_ctx_add_ta(ctx, "...");
- *	... some lookups
- *	... call ub_ctx_delete(ctx); when you want to stop.
- *
- * Application not threaded. Blocking.
- *	int err = ub_resolve(ctx, "www.example.com", ...
- *	if(err) fprintf(stderr, "lookup error: %s\n", ub_strerror(err));
- *	... use the answer
- *
- * Application not threaded. Non-blocking ('asynchronous').
- *      err = ub_resolve_async(ctx, "www.example.com", ... my_callback);
- *	... application resumes processing ...
- *	... and when either ub_poll(ctx) is true
- *	... or when the file descriptor ub_fd(ctx) is readable,
- *	... or whenever, the app calls ...
- *	ub_process(ctx);
- *	... if no result is ready, the app resumes processing above,
- *	... or process() calls my_callback() with results.
- *
- *      ... if the application has nothing more to do, wait for answer
- *      ub_wait(ctx); 
- *
- * Application threaded. Blocking.
- *	Blocking, same as above. The current thread does the work.
- *	Multiple threads can use the *same context*, each does work and uses
- *	shared cache data from the context.
- *
- * Application threaded. Non-blocking ('asynchronous').
- *	... setup threaded-asynchronous config option
- *	err = ub_ctx_async(ctx, 1);
- *	... same as async for non-threaded
- *	... the callbacks are called in the thread that calls process(ctx)
- *
- * If no threading is compiled in, the above async example uses fork(2) to
- * create a process to perform the work. The forked process exits when the 
- * calling process exits, or ctx_delete() is called.
- * Otherwise, for asynchronous with threading, a worker thread is created.
- *
- * The blocking calls use shared ctx-cache when threaded. Thus
- * ub_resolve() and ub_resolve_async() && ub_wait() are
- * not the same. The first makes the current thread do the work, setting
- * up buffers, etc, to perform the work (but using shared cache data).
- * The second calls another worker thread (or process) to perform the work.
- * And no buffers need to be set up, but a context-switch happens.
