${prog} [<options>]
|
|
|
|
<options> can be one of the following:
|
|
|
|
--prefix=<val> The installation prefix (default: /usr).
|
|
--enable-debug Enable debug mode compilation (default: disabled).
|
|
--disable-allocator Disable use of internal memory allocator mechanism (default: enabled).
|
|
--enable-debug-stats Enable printing of some verbose debug info (default: disabled).
|
|
--with-libbsc=<path to libbsc source>
|
|
Enable support for libbsc (See: libbsc.com). Full path to the libbsc
|
|
source tree must be provided. It links the library statically.
|
|
--with-openssl=<path to OpenSSL installation tree> (Default: System)
|
|
This defaults to the system's OpenSSL library. You can use this option
|
|
if you want to use an alternate OpenSSL installation.
|
|
--with-zlib=<path to zlib installation tree> (Default: System)
|
|
Enable building against an alternate Zlib installation.
|
|
--with-bzlib=<path to Bzip2 library installation tree> (Default: System)
|
|
Enable building against an alternate Bzip2 and library installation.
|
|
--use-key256 Use 256-bit encryption keys. Default key length is 128-bit.
|
|
--help Display this help message.
