    <p>I started studying POSIX timers, so I started also doing some exercises, but I immediately had some problems with the compiler. When compiling this code, I get some strange messages about macros like CLOCK_MONOTONIC. Those are defined in various libraries like time.h etc. but the compiler gives me errors as if they are not defined.</p> <p>It is strange because I am using a Fedora 16, and some of my friends with Ubuntu get less compiler errors than I :-O</p> <p>I am compiling with <code>gcc -O0 -g3 -Wall -c -fmessage-length=0 -std=c99 -lrt</code></p> <p>Here the errors I get:</p> <ul> <li><p><code>struct sigevent sigeventStruct</code> <strong>gives</strong>:</p> <pre><code>storage size of ‘sigeventStruct’ isn’t known unused variable ‘sigeventStruct’ [-Wunused-variable] Type 'sigevent' could not be resolved unknown type name ‘sigevent’ </code></pre></li> <li><p><code>sigeventStruct.sigev_notify = SIGEV_SIGNAL</code> <strong>gives</strong>:</p> <pre><code>‘SIGEV_SIGNAL’ undeclared (first use in this function) request for member ‘sigev_notify’ in something not a structure or union Field 'sigev_notify' could not be resolved </code></pre></li> <li><p><code>if(timer_create(CLOCK_MONOTONIC, sigeventStruct, numero1) == -1)</code> <strong>gives</strong>:</p> <pre><code>implicit declaration of function ‘timer_create’ [-Wimplicit-function- declaration] ‘CLOCK_MONOTONIC’ undeclared (first use in this function) Symbol 'CLOCK_MONOTONIC' could not be resolved </code></pre></li> </ul> <p>Here is the code:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;fcntl.h&gt; #include &lt;time.h&gt; #include &lt;stdlib.h&gt; #include &lt;errno.h&gt; #include &lt;unistd.h&gt; #include &lt;signal.h&gt; int main() { timer_t numero1; struct sigevent sigeventStruct; sigeventStruct.sigev_notify = SIGEV_SIGNAL; if(timer_create(CLOCK_MONOTONIC, sigeventStruct, numero1) == -1) { printf( "Errore: %s\n", strerror( errno ) ); } return 0; } </code></pre>

    1. COJust a suggestion, instead of having the errors in point-form, just copy them exactly as they are inside a `<pre></pre>` block in the question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
