\`configure' configures tdl to adapt to many kinds of systems.
Usage: ./configure [OPTION]...
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
By default, \`make install' will install all the files in
\`/usr/local/bin', \`/usr/local/lib' etc. You can specify
an installation prefix other than \`/usr/local' using \`--prefix',
for instance \`--prefix=$HOME'.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--infodir=DIR info documentation [PREFIX/info]
--mandir=DIR man documentation [PREFIX/man]
--docdir=DIR other documentation [PREFIX/doc/mairix-\$version]
Other options:
--enable-gzip-mbox attempt to support gzipped mboxes (requires zlib)
--disable-gzip-mbox don't attempt to support gzipped mboxes
--enable-bzip-mbox attempt to support bzip2ed mboxes (requires bzlib)
--disable-bzip-mbox don't attempt to support bzip2ed mboxes
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
CPPFLAGS Extra C preprocessor flags, e.g. -I<include dir> if you
have header files in a nonstandard directory <include dir>
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
Use these variables to override the choices made by \`configure' or to help
it to find libraries and programs with nonstandard names/locations.
