address@hidden embedded systems
address@hidden portability
+
address@hidden uses the standard GNU system where the usual build process
+involves running
address@hidden
+$ ./configure
+$ make
+$ make install
address@hidden verbatim
+
address@hidden supports various options to be given to configure to tailor the
+binary to a specific situation.  Note that some of these options will
+remove portions of the @mhd{} code that are required for
+binary-compatibility.  They should only be used on embedded systems
+with tight resource constraints and no concerns about library
+versioning.  Standard distributions including @mhd{} are expected to
+always ship with all features enabled, otherwise unexpected
+incompatibilities can arise!
+
+Here is a list of @mhd{}-specific options that can be given to configure
+(canonical configure options such as ``--prefix'' are also supported, for a
+full list of options run ``./configure --help''):
+
address@hidden 
address@hidden ``--disable-curl''
+disable running testcases using libcurl
+
address@hidden ``--disable-largefile'' 
+disable support for 64-bit files
+
address@hidden ``--disable-messages''
+disable logging of error messages (smaller binary size, not so much fun for 
debugging)
+
address@hidden ``--disable-https''
+disable HTTPS support, even if GNUtls is found; this option must be used if 
eCOS license is desired as an option (in all cases the resulting binary falls 
under a GNU LGPL-only license)
+
address@hidden ``--disable-postprocessor''
+do not include the post processor API (results in binary incompatibility)
+
address@hidden ``--disable-dauth''
+do not include the authentication APIs (results in binary incompatibility)
+
address@hidden ``--enable-coverage''
+set flags for analysis of code-coverage with gcc/gcov (results in slow, large 
binaries)
+
address@hidden ``--with-gcrypt=PATH''
+specifies path to libgcrypt installation
+
address@hidden ``--with-gnutls=PATH''
+specifies path to libgnutls installation
