These issues include software that isn't specific to Arch Linux but provides solutions assuming this software is operating within Arch Linux by some means or another. These are also specific to my own personal experience through my own requirements/preferences and assumptions and may be one of many possible solutions to that same problem.
They may also be more than likely not the most optimal solutions to these issues in regard to what others with greater understanding and experience with this software would suggest.
These are just solutions that worked for my own needs.

Programming - Application Unable To Reference Shared Library In Local Lib
By default only the /usr/lib directory can be referenced by developed applications but it is preferable to install custom application libraries into the /usr/local/lib directory.
There are two methods to fix this, one using the ldconfig command and the other by modifying the LD_LIBRARY_PATH environment variable in the bashrc file. The first method is preferred as it is sometimes unadvisable to manually modify the LD_LIBRARY_PATH for linking purposes.
Method 1 actually modifies the environment system wide and doesn't require a shell restart where Method 2 just modifies the local user shell environment only and the shell must be restarted for the changes to take effect.
Method 1: LDCONFIG
| Navigate to the ld.so.conf.d directory |
# cd /etc/ld.so.conf.d
|
| Create/Open new liblocal.conf file |
# micro locallib.conf
|
| Add line |
/usr/local/lib
|
| Save & Exit Micro Text Editor |
CTRL+S, CTRL+Q
|
| Update LDCONFIG
|
# ldconfig
|
Method 2: BASHRC
| Modify user BASHRC file |
$ micro ~/.bashrc
|
| Append line |
export LD_LIBRARY_PATH="/lib:/usr/lib:/usr/local/lib"
|
| Save & Exit Micro Text Editor |
CTRL+S, CTRL+Q
|
| Restart Shell/Terminal Session |
As Required |

QMMP - New Theme Skins Won't Add
In Settings/Appearance/Skins. Adding a new skin file will not add the new skin into the selection list. Even if the Refresh button is pressed and/or the program restarted.
It was noticed though that the archive file for the skin is still copied into the ~./config/qmmp/skins folder.
A little research brought around the fact that the unzip package needs to be installed to allow the extraction of the skin archives. Which in my case is wasn't. The Arch qmmp package didn't include this as a dependancy so it happily installed without unzip; obviously allowing this problem to occur unexpectedly.
So, to fix this just run;
| Install The unzip Archive Extracter/Viewer |
# pacman -S unzip
