@subsection Using the GNU MP Library
@cindex GMP
Starting with version 1.1, CLN may be configured to make use of a
preinstalled @code{gmp} library for some low-level routines. Please
make sure that you have at least @code{gmp} version 3.0 installed
since earlier versions are unsupported and likely not to work. This
feature is known to be quite a boost for CLN's performance.
CLN may be configured to make use of a preinstalled @code{gmp} library
for some low-level routines. Please make sure that you have at least
@code{gmp} version 3.0 installed since earlier versions are unsupported
and likely not to work. Using @code{gmp} is known to be quite a boost
for CLN's performance.
By default, CLN will autodetect @code{gmp} and use it. If you do not
want CLN to make use of a preinstalled @code{gmp} library, then you can
explicitly specify so by calling @code{configure} with the option
@samp{--without-gmp}.
By default, CLN will autodetect @code{gmp} and use it. But if you have
installed the @code{gmp} library and its header file in some place where
your compiler cannot find it by default, you must help @code{configure}
by setting @code{CPPFLAGS} and @code{LDFLAGS}. Here is an example:
If you have installed the @code{gmp} library and its header files in
some place where the compiler cannot find it by default, you must help
@code{configure} and specify the prefix that was used when @code{gmp}
was configured. Here is an example:
@example
$ CFLAGS="-O2" CXXFLAGS="-O2" CPPFLAGS="-I/opt/gmp/include" \
LDFLAGS="-L/opt/gmp/lib" ./configure --with-gmp
$ ./configure --with-gmp=/opt/gmp-4.2.2
@end example
If you do not want CLN to make use of a preinstalled @code{gmp}
library, then you can explicitly specify so by calling
@code{configure} with the option @samp{--without-gmp}.
This assumes that the @code{gmp} header files have been installed in
@file{/opt/gmp-4.2.2/include/} and the library in
@file{/opt/gmp-4.2.2/lib/}. More uncommon GMP installations can be
handled by setting CPPFLAGS and LDFLAGS appropriately prior to running
@code{configure}.
