tlbuild: Configure options
7 Configure options
*******************
Corresponding to the large number of program and library modules there
are a large number 'configure' options, most of which are described
here. The command
'configure --help'
at the top level gives an exhaustive list of all global options and a
few important module-specific ones, whereas, e.g.,
'texk/lcdf-typetools/configure --help'
also displays the 'lcdf-typetools' specific options, which are not shown
at the top level.
The help text also mentions several influential environment
variables, but for TeX Live it is better to specify them as assignments
on the command line.
The './Build' script used to make the binaries shipped with TeX Live
invokes the top-level 'configure' with a few additional options (⇒
Building). The defaults discussed below are those for the actual
'configure' script; invoking 'configure' via './Build' yields different
results.
Defaults for most options are set at the top level and propagated
explicitly to all subdirectories. Options specified on the command line
are checked for consistency but never modified.
