+Moreover, you should never call the autotools manually since you must run
+them in a specific order with specific arguments. Most of the times, the
+makefiles will automatically call the tools for you. When it's not possible
+(such as the first time you checkout the CVS), use the ./bootstrap command
+to call them explicitely.
+
+If you need to compile the CVS version on a machine where all these
+dependencies are not met, the easiest is to do <tt>make dist</tt> in the CVS
+dir, on another machine where all dependencies are met. It will create an
+archive you may deploy on other sites just as a regular stable release.

\subsection faq_setting_MSG Setting up your own MSG code
Do not build your simulator by modifying the SimGrid examples. Go
Program (cross-)compiled with mingw32 do request an extra DLL at run-time to be
usable. For example, if you want to test your build with wine, you should do
the following to put this library where wine looks for DLLs.
-\verbatim cp /usr/share/doc/mingw32-runtime/mingwm10.dll.gz ~/.wine/c/windows/system/

+cp /usr/share/doc/mingw32-runtime/mingwm10.dll.gz ~/.wine/c/windows/system/
gunzip ~/.wine/c/windows/system/mingwm10.dll.gz

+\subsection faq_MIA_communication_time How can I get the *real* communication time ?
+
+Communications are synchronous and thus if you simply get the time
+before and after a communication, you'll only get the transmission
+time and the time spent to really communicate (it will also take into
+account the time spent waiting for the other party to be
+ready). However, getting the *real* communication time is not really
+hard either. The following solution is a good starting point.
+
+\verbatim
+int sender()
+{
+ m_task_t task = MSG_task_create("Task", task_comp_size, task_comm_size,
+ calloc(1,sizeof(double)));
+ *((double*) task->data) = MSG_get_clock();
+ MSG_task_put(task, slaves[i % slaves_count], PORT_22);
+ INFO0("Send completed");
+ return 0;
+}
+int receiver()
+{
+ m_task_t task = NULL;
+ double time1,time2;
+
+ time1 = MSG_get_clock();
+ a = MSG_task_get(&(task), PORT_22);
+ time2 = MSG_get_clock();
+ if(time1<*((double *)task->data))
+ time1 = *((double *) task->data);
+ INFO1("Communication time : \"%f\" ", time2-time1);
+ free(task->data);
+ MSG_task_destroy(task);
