# Garlic Installation

garlic, free molecular viewer and editor, free molecular visualization program, protein structure, DNA structure, PDB, molecular rendering, biological macromolecule, unix, linux, free software download, open source software, Damir Zucic.

Garlic is the most portable molecular viewer/editor in the unix world, because the only libraries required by this program are the standard C library (libc), the standard math library (libm) and the standard X library (libX11). All other molecular visualization programs require some additional libraries.
Before starting the installation, you might be interested to check the technical requirements . Most contemporary unix and unix-like systems (like linux) meet these requirements without need to change the configuration, so you can skip this text if you are impatient.
If you have Apple McIntosh running Xtools from Tenon, please read these hints , contributed by Chris from Macinchem.
To compile and install garlic, follow these instructions:

(1) | Put garlic package (garlic-1.4.tar.gz) into some empty directory.
(2) | Uncompress and unpack the package: gzip -d garlic-1.4.tar.gz tar xf garlic-1.4.tar
(3) | Change your working directory: cd garlic-1.4
(4) | Check which C compiler is available on your system. If you don't know how to find this information, try this: man -k compiler to obtain the list of available compilers.
(5) | If gcc (GNU C) compiler is not available on your system, use your favorite editor to edit Makefile. Replace gcc in: CC = gcc line with the name of your compiler (this may be cc, for example). If gcc is available on your system, do not change the CC line.

(6)

Find a directory which contains the Xlib library. Try this:
cd /
find . -name libX11\*
Check where is the file libX11.so (sharable library - prefered)
or libX11.a (static library - reserve option).
If your directory is different from /usr/X11R6/lib, modify the line:
LIBPATH = -L/usr/X11R6/lib
in Makefile. For example, if libX11.so is stored in /usr/shlib
directory on your system, the LIBPATH should be changed to:
LIBPATH = -L/usr/shlib

(7) | Compile the package - just type: make and wait, it will take some time.
(8) | If everything worked fine, copy the executable to a choosen directory. /usr/local/bin may be a good choice. This job should be done by root (system administrator): cp garlic /usr/local/bin If you don't have root privileges, ask your local administrator to install garlic, or just leave it in one of your directories.

(9)

Now the .garlicrc configuration file and the file which contains the
template residues should be copied to a directory where these files
will be accessible to everyone. If this is not done, garlic will work
anyway, using hard-coded default configuration, but you will be unable
to replace residues and to create peptides.
The recommended directory is /usr/local/lib/garlic but if directory
/usr/local/lib does not exist on your system, /usr/lib/garlic may be
may be used. This should be done by root (system administrator):
mkdir /usr/local/lib/garlic
cp .garlicrc /usr/local/lib/garlic
cp residues.pdb /usr/local/lib/garlic

(10)

It may be good idea to copy the configuration file to your home directory
or to the subdirectory garlic of your home directory. The same may be
done with the file residues.pdb. If you do this, you will be able to
personalize your garlic sessions, because your private files will override
the system-wide defaults. Of course, you don't need root privileges
to do this:
cp .garlicrc $HOME
cp residues.pdb $HOME
or:
mkdir $HOME/garlic
cp .garlicrc $HOME/garlic
cp residues.pdb $HOME/garlic

(11) | It is recommended to set the environment variable MOL_PATH, so garlic will search all directories listed in this variable to find the specified file. Click here for detailed instructions.
(12) | Clean up the mess (sources and .o files). Be sure to leave all .pdb files for later practice. Leave also the files with the extension .script, these are some garlic tutorial scripts.

If garlic refuses to work because it fails to get the TrueColor visual, try to execute
xdpyinfo and xwininfo (click into the root window); check the list of supported visuals
and the current color depth. Choose the color depth for which the TrueColor visual
is available. If you have the SGI Octane workstation, please read this text ,
