 +====October 17, 2013====
 +Matt finished the make file for our stack program. Matt's code is included at the bottom of this entry. Information on Make files can be found [[http://lab46.corning-cc.edu/documentation/makefile|here]]. To use Matt's Make file:
  
 +__**On a lab46 terminal:**__
 +<cli>$ cd /var/public/data/fall2013/linkedlistimp</cli>
 +**Then copy the contents of the directory:**
 +  * **To copy into your ~/src/datas/ directory:**
 +<cli>$ make copy</cli>
 +  * **To copy into a different directory:**
 +<cli>$ cp -a ~/src/dir</cli>
 +
 +__**In Matt's Make file:**__
 +  * Variables are at the top.
 +  * Then there are "Labels" that run a set of "rules".
 +  * Written in "MAKEFILE" and runs set of Bash commands.
 +  * The **/inc** directory contains only headers.
 +  * The **/lib** directory contains only libraries.
 +  * The **/src** directory contains only the source code. //**Note:** The parts rule equals the running of the shell command. This means Matt's Make file will only work on a Unix system.//
 +  * **ar:** Sets up the archiver.
 +  * **cc:** Sets up the compiler.
 +  * **src:** Lists  all .c files in the src directory.
 +  * **obj:** Turns every .c file into a .o object file.
 +  * **lib:** Finds the current directory the script is in.
 +  * **all:** Compiles src, handles objects, handles libraries.
 +  * **debug rule:** Checks to see if the source code was compiled with debug symbols.
 +  * **lib rule:** Checks library information.
 +  * **clean rule:** Removes all .o object files.
 +  * **testing dir:** Makes the libraries, renames the executable from the source code, then builds the final executable.
 +
 +__**To use Matt's Make file:**__
 +  - <cli>$ make</cli>
 +  - <cli>$ ls lib</cli> Shows the newly made .lib files.
 +  - <cli>$ make clean</cli> Removes all the object files.
 +  - <cli>$ make debug</cli> Builds the source code with debugging symbols. Not required but good practice; can also use "make".

 +I'm finding that GDB is quickly becoming an indispensable and invaluable tool when finding and fixing bugs. The command alias **gcc='gcc -g'** won't negatively effect anything in the future, so I'll make it an alias. Also, Google has some nice GDB "cheat sheets" that will come in handy.
 +
 +I had the idea to use 2 lists instead of modifying just 1. My logic is complicated and that logic seems far more simpler; and hopefully simpler to implement.
 +
 +**Pseudocode/Logic steps:**
 +  - Create 2 lists: (Not sure this will work; Could copy tmp's list into tmp2's list, then call clearList() on tmp2?).
 +    - tmp  -> unsorted list.
 +    - tmp2 -> sorted list. 
 +  - Find the lowest value in tmp's list
 +  - Insert that value into tmp2's list
 +  - Remove the lowest value from tmp's list
 +  - Repeat steps 2-4 until the program is at the end of the tmp's list.
 +    - Not sure if this is needed; delete empty tmp list?
 +  - Display tmp2's sorted list.
