CMake names environment variables using an ENV prefix and surrounding the names in curly braces. Here is an example: MESSAGE("$ENV{PATH}") Reading variables will work in any version of CMake. Writing to them works in CMake 2.2 and higher using the following syntax: SET(ENV{HELLO} "World") Note that there is currently no way to tell apart an empty environment variable value from a variable that is not set at all.

None! The most generic environment for TeX only requires that your PATH be setup appropriately. This is done by default, so you should not need to set any environment variables unless you have special requirements beyond that of most users of TeX. If you find that you do need to set some environment variables you should read the help file on Kpathsea library. The library's purpose is to look up a file in a list of directories specified by the user.

Altering the global environment is platform dependent, and there are limits no matter what you do. In Windows NT, all environment variables are actually registry entries. The system initializes the process environment block based of the registry, and also the environment block of the process that creates the process. Applications can choose to be aware of changes to environment variables by paying attention to the WM_SETTINGCHANGE message.

The cache variables listed in the GUI when you press "Configure" are used to initialize the values seen by the code in CMakeLists.txt files. Changes made by the code are used during the configure step and seen by the generators but are not stored back into the cache. For example: SET(BUILD_SHARED_LIBS ON) will turn on building of shared libraries for the directory containing the command and all subdirectories, but the change will not appear in the GUI.

Most of you will be using default - Common desktop window manager that came with Solaris. If you need to run your own window manager, please read on. You need to have /opt/X11R6/bin (Solaris 2.x) or /usr/openwin/bin in your path. In your home directory you should create a file ".xinitrc". ".xinitrc" is the script used to start up X and it is invoked when you type "xinit".

export ENVVARNAME=VALUE, so, for Full Scene Anti-Aliasing you might export __GL_FSAA_MODE=4 before running your game. See the nVidia documentation for a list of options.

Starting in maven 2.0.1, you can reference windows and unix environment variables inside your pom.xml or settings.xml using an expression of the form:

However, SLIB provides getenv. Particular implementations may provide functions, e.g. Guile provides getenv.

Save it with any name and run it on your browser. The script returns the default Environment variables. Five important environment variables are available to your CGI script to help in identifying the end user. HTTP_FROM This environment variable is, theoretically, set to the email address of the user. However, many browsers do not set it at all, and most browsers that do support it allow the user to set any value for this variable.

Alpha systems have a variety of variables with values set up within the SRM system console. These environment variables control the particular behaviour of the console program and the system hardware, the particular console interface presented to the operating system, various default values for the operating system bootstrap, and related control mechanisms---in other words, "the environment variables provide an easily extensible mechanism for managing complex console state.

You can get a listing of environment variables from your own server with the following two-line Perl program:

For Jim Hall's Help program, you need to set the PAGER and HELPPATH environment variables in Autoexec.bat. Reasonable values are: Note that Joe Cosentino has written an html Help program, and we will switch to that when we have enough support for it. Unless otherwise stated, FD-DOC HOWTO documents are copyrighted by their respective authors.

CMake build settings are stored in the CMake cache corresponding to a project's build tree. They are called CMake "cache entries" and have no relation to your command shell's environment variables. Use a CMake GUI (CMakeSetup on Windows or ccmake on UNIX) or the wizard mode (cmake -i) to edit cache entries. Initial values may also be specified for a build by using the -D command line argument to cmake when it is first run to produce a new build tree.

Edit the file ~/.Xdefaults (create it in your home directory if it does not exist) and add the following line: *loginShell:true Save the changes and logout/login. Any terminals that you open will have /etc/profile executed automatically (so that STAF's InstallShield environment variable updates will be read).

There are two timezone-related settings: $wgLocaltimezone and $wgLocalTZoffset. Set both in LocalSettings.php. $wgLocaltimezone is used for formatting the timezone in signatures, and should be set to the locale name, for example "Europe/Berlin". $wgLocalTZoffset sets the default user preference the number of hours your local time differs from server time, and is used for timestamps seen in recent changes and history views.
