    <p>Okay so I need to make a basic Makefile for a program I wrote. Here are the files:</p> <pre><code>list.c hash.c order_book.c libdefault_hash.a //provided already so I do not need to create. </code></pre> <p>I need to create libraries for list.c and hash.c so that orderbook can use them when it compiles. So this is what I currently have in <code>Makefile</code>:</p> <pre><code>all: orderbook orderbook: orderbook.c liblist.a libhash.a gcc -std=c99 -o orderbook order_book.c list.c -L. -llist -lhash -libdefault_hash liblist.a: list.c gcc -std=c99 -c list.c ar rcu liblist.a list.o libhash.a: hash.c gcc -std=c99 -c hash.c ar rcu libhash.a hash.o </code></pre> <p>My understanding of how makefiles work is very small but here is my thought process,</p> <ol> <li><code>all: orderbook</code> will mean that <code>orderbook:</code> will run.</li> <li><code>orderbook.c</code> will then compile, then the code will compile the libraries.</li> <li><p>Once the libraries are compiled it will run:</p> <p><code>gcc -std=c99 -o orderbook order_book.c list.c -L. -llist -lhash -libdefault_hash</code></p></li> </ol> <p>And the result should be a simple program file named orderbook, but the terminal prints out:</p> <pre><code>$ make gcc -std=c99 -o orderbook order_book.c list.c hash.c -L. -llist -lhash -libdefault_hash /usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible ./liblist.a when searching for -llist /usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -llist /usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -libdefault_hash collect2: ld returned 1 exit status make: *** [orderbook] Error 1 $ </code></pre> <p>Any help/guidance is much appreciated.</p>

    1. COnitpick: the makefile itself doesn't contain any C code; you just happen to be using it to compile something *else* written in C.

    2. COWhy does Make not attempt to build the libraries before the executable? I'll guess: you built the libraries in a previous step you're not showing us. Why does `list.c` appear in the compiler command which also calls on `liblist.a`? I'll take another guess: you haven't gotten that commands to work from the command line. **You must know how to build a file, before you can tell Make how to build it.**

    3. CONote: You may want to use -ldefault_hash while your doing this. The nomenclature seems a bit incorrect compared to your other libs. Been awhile since I did this, do ymmv. And there are considerably easier ways to do this. and `list.c` should not be on the compilation line for `orderbook`; its already in `liblist.a`

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.
