tlbuild: Variables for configure
7.4 Variables for configure
===========================
The values for these variables can be specified as 'configure' arguments
of the form 'VAR=VALUE'. They can also be defined in the environment,
but that might not work for cross compilations.
'CC'
'CXX'
'CPPFLAGS'
And plenty more. As usual with Autoconf, these variables specify
the name (or full path) of compilers, preprocessor flags, and
similar. ⇒(autoconf)Preset Output Variables.
'CLISP'
Name (or full path) of the 'clisp' executable, used to build
'xindy'.
'FT2_CONFIG'
'ICU_CONFIG'
'PKG_CONFIG'
These specify the name (or path) for the 'freetype-config',
'icu-config', and 'pkg-config' commands used to determine the flags
required for system versions of 'libfreetype', the ICU libraries,
and other libraries, respectively.
'KPSEWHICH'
Name (or path) of an installed 'kpsewhich' binary, used by 'make
check' to determine the location of, e.g., 'cmbx10.tfm'.
'MAKE'
'SED'
And more. Name (or path) of the 'make', 'sed', and similar
programs; used at the top level and propagated to all
subdirectories.
'PERL'
'LATEX'
'PDFLATEX'
Name (or full path) for the 'perl', 'latex', and 'pdflatex'
commands used, e.g., to build the 'xindy' documentation.
