Dynamic variables

Dynamic variables

Compile automatically creates variables that can be used in the functions.

System variables

To help you in recipe writing, Compile gives you the following run-time variables to use, each referring to a specific filesystem hierarchy’s member.

$VARIABLE       :       DEFAULT PATH
==============================================
$goboExecutables:       /System/Index/bin
$goboHeaders    :       /System/Index/include
$goboModules    :       /System/Kernel/Modules
$goboLibraries  :       /System/Index/lib
$goboPrograms   :       /Programs
$goboSettings   :       /System/Settings
$goboTemp       :       /System/Variable/tmp
$goboVariable   :       /System/Variable

Thus, if you’re writing a recipe for some program which accepts configure options and for which you need to manually specify a library path, you can use the $goboLibraries variable like

configure_options=(
  "--with-extra-libraries=$goboLibraries/<path_to_the_library>"
)

The same applies to the remaining as well, depending on specific program’s needs.

Program variables

For every recipe there will always be variables for the program prefix as well as variables for the settings directory and the variable directory for the program.

• $target
• $settings_target
• $variable_target

For the recipe for Foobar 2.1 those variables will have the values of $goboPrograms/FooBar/2.1, $goboPrograms/FooBar/Settings and $goboPrograms/FooBar/<b></b>Variable respectively.

Dependency variables

There will also be variables for every dependency listed in the Dependency file. If for example Foo 1.2 is listed as dependency, the variables will be called

• $foo_path
• $foo_settings_path
• $foo_variable_path
