    <p>I installed Cilk successfully on my home computer, a 32-bit machine running Ubuntu. I replicated the process to the best of my knowledge on my 64-bit Ubuntu netbook, excepting, of course, that I downloaded the 64-bit version instead of the 32-bit version. When attempting to run the very simple cilkexample.c copied below, however, I get very very many errors, all seeming related to it not having access to library files:</p> <pre><code>In file included from /usr/include/stdio.h:28, from cilkexample.c:1: /usr/include/features.h:323:26: error: bits/predefs.h: No such file or director\ y /usr/include/features.h:356:25: error: sys/cdefs.h: No such file or directory /usr/include/features.h:388:23: error: gnu/stubs.h: No such file or directory In file included from cilkexample.c:1: /usr/include/stdio.h:36:25: error: bits/types.h: No such file or directory /usr/include/stdio.h:161:28: error: bits/stdio_lim.h: No such file or directory /usr/include/stdio.h:846:30: error: bits/sys_errlist.h: No such file or directo\ ry In file included from /usr/include/stdio.h:34, from cilkexample.c:1: /usr/local/cilk/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.2.4/include/stddef.h:\ 214: error: expected constructor, destructor, or type conversion before ‘typede\ f’ In file included from cilkexample.c:1: /usr/include/stdio.h:49: error: expected constructor, destructor, or type conve\ rsion before ‘typedef’ </code></pre> <p>et cetera, et cetera, et cetera.</p> <p>Here is the file I attempted to compile with the command <code>cilk++ -o cilkexample cilkexample.c</code>:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;cilk.h&gt; int foo() { return 100; } int bar() { return 50; } int cilk_main(int argc, char **argv) { int x, y; x = cilk_spawn foo(); y = cilk_spawn bar(); cilk_sync; printf("Got %d %d, expecting %d %d\n", x, y, 100, 50); return 0; } </code></pre> <p>Again, I think this has to be a configuration problem. The code is unmodified from the working version our professor distributed, which I tested on a separate machine.</p> <p>Last bit of information I can think of is the PATH.</p> <pre><code>******@********:~/Path/To/Cilk$ echo $PATH /usr/local/cilk/bin/:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games </code></pre> <p>Thanks for your help!</p>

    1. COIt looks like your installation is messed up and you're missing lots of header files, but not all, since your inclusion of stdio.h works.

    2. CO@jv42, I think you're right, but I don't know what to do about this. :)

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.
