    <p>I'm trying to code a printf clone. I've built a library file called "libftprintf.a" but when I try to use it, I get the following error, on Mac OSX 10.8.5:</p> <pre><code>ld: warning: ignoring file ./libftprintf.a, file was built for archive which is not the architecture being linked (x86_64): ./libftprintf.a </code></pre> <p>Strangely this works fine (but I need only one lib called libftprintf, so this is not acceptable):</p> <pre><code>gcc -Wall -Wextra -Werror -I libft/includes/ -o ft_printf_test.bin -L libft -lft -L. -lftprintf ft_printf_test.c </code></pre> <p>I suspect I have misused the <code>ar</code> command to link both libs together. But I don't se my mistake yet.</p> <p><strong>What could be the cause of that?</strong></p> <p>Everything seems to compile just fine until I try to use the <code>libftprintf.a</code> file with the <code>make test</code> command. I've searched for a solution on Google, but most answers relate to XCode only.

    2. COIf you move `-L. -lftprintf` to be *after* the file arguments, does that help? http://gcc.gnu.org/onlinedocs/gcc/Link-Options.html#Link-Options says "It makes a difference where in the command you write this option; the linker searches and processes libraries and object files in the order they are specified."

    3. COYes. Everything on the same machine. Strangely, if I do `gcc -I libft/includes/ ft_printf_test.c ft_printf.c libft/libft.a`, it compiles and runs just fine. @MarkPlotnick: Moving -L. -lftprintf after the file arguments does not help.

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.
