<p>On systems ‘<samp>*-*-aix[34]*</samp>’ shared libraries are disabled by default, since

some versions of the native <code>ar</code> fail on the convenience libraries

used. A shared build can be attempted with

|
||
|
|
|

|
|
<p>Note that the ‘<samp>--disable-static</samp>’ is necessary because in a shared build
|
||
|
|
libtool makes <samp>libgmp.a</samp> a symlink to <samp>libgmp.so</samp>, apparently for
|
||
|
|
the benefit of old versions of <code>ld</code> which only recognise <samp>.a</samp>,
|
||
|
|
but unfortunately this is done even if a fully functional <code>ld</code> is
|
||
|
|
available.

|

|
<p>On systems ‘<samp>arm*-*-*</samp>’, versions of GCC up to and including 2.95.3 have a
|
||
|
|
bug in unsigned division, giving wrong results for some operands. GMP
|
||

‘<samp>./configure</samp>’ will demand GCC 2.95.4 or later.

<p>Compaq C++ on OSF 5.1 has two flavours of <code>iostream</code>, a standard one and
|
||
|
|
an old pre-standard one (see ‘<samp>man iostream_intro</samp>’). GMP can only use the
|
||
|
|
standard one, which unfortunately is not the default but must be selected by
|
||
|
|
defining <code>__USE_STD_IOSTREAM</code>. Configure with for instance
|

<p>On some systems, the hardware floating point has a control mode which can set
|
||
|
|
all operations to be done in a particular precision, for instance single,
|
||
|
|
double or extended on x86 systems (x87 floating point). The GMP functions
|
||
|
|
involving a <code>double</code> cannot be expected to operate to their full
|
||
|
|
precision when the hardware is in single precision mode. Of course this
|
||
|
|
affects all code, including application code, not just GMP.

<p><code>m4</code> in these releases of FreeBSD has an eval function which ignores

|
|
choose another m4 in the <code>PATH</code>. The bug is fixed in FreeBSD 9.3 and 10.0,
|
||
|
|
so either upgrade or use GNU m4. Note that the FreeBSD package system installs

GNU m4 under the name ‘<samp>gm4</samp>’, which GMP cannot guess.

<p>GMP releases starting with 6.0 do not support ‘<samp>ABI=32</samp>’ on FreeBSD/amd64

<p>Microsoft also publishes an Interix “Services for Unix” which can be used to

<p>On systems ‘<samp>*-*-cygwin*</samp>’, ‘<samp>*-*-mingw*</samp>’ and ‘<samp>*-*-pw32*</samp>’ by

<p>Static and DLL libraries can’t both be built, since certain export directives

in <samp>gmp.h</samp> must be different.

|

|
<p>A MINGW DLL build of GMP can be used with Microsoft C. Libtool doesn’t
|
||
|
|
install a <samp>.lib</samp> format import library, but it can be created with MS
|
||
|
|
<code>lib</code> as follows, and copied to the install directory. Similarly for
|

|
|
<samp>libmp</samp> and <samp>libgmpxx</samp>.

<p>MINGW uses the C runtime library ‘<samp>msvcrt.dll</samp>’ for I/O, so applications
|
||
|
|
wanting to use the GMP I/O routines must be compiled with ‘<samp>cl /MD</samp>’ to do
|
||
|
|
the same. If one of the other C runtime library choices provided by MS C is
|
||
|
|
desired then the suggestion is to use the GMP string functions and confine I/O
|
||
|
|
to the application.

|
<p>In GMP, CPU types ‘<samp>power*</samp>’ and ‘<samp>powerpc*</samp>’ will each use instructions
|
||
|
|
not available on the other, so it’s important to choose the right one for the
|
||
|
|
CPU that will be used. Currently GMP has no assembly code support for using
|
||
|
|
just the common instruction subset. To get executables that run on both, the
|
||
|
|
current suggestion is to use the generic C code (<samp>--disable-assembly</samp>),
|
||
|
|
possibly with appropriate compiler options (like ‘<samp>-mcpu=common</samp>’ for
|
||
|
|
<code>gcc</code>). CPU ‘<samp>rs6000</samp>’ (which is not a CPU but a family of
|
||
|
|
workstations) is accepted by <samp>config.sub</samp>, but is currently equivalent to
|
||
|
|
<samp>--disable-assembly</samp>.

|

<p>‘<samp>sparcv8</samp>’ or ‘<samp>supersparc</samp>’ on relevant systems will give a
|

significant performance increase over the V7 code selected by plain
|
||

‘<samp>sparc</samp>’.

<dd><a name="index-Sparc-1"></a>
|
||
|
|
<p>The GMP assembly code for both 32-bit and 64-bit Sparc clobbers the
|
||
|
|
“application registers” <code>g2</code>, <code>g3</code> and <code>g4</code>, the same way
|
||
|
|
that the GCC default ‘<samp>-mapp-regs</samp>’ does (see <a href="http://gcc.gnu.org/onlinedocs/gcc/SPARC-Options.html#SPARC-Options">SPARC
|
||
|
|
Options</a> in <cite>Using the GNU Compiler Collection (GCC)</cite>).
|
||
|
|
</p>
|
||
|
|
<p>This makes that code unsuitable for use with the special V9
|
||
|
|
‘<samp>-mcmodel=embmedany</samp>’ (which uses <code>g4</code> as a data segment pointer), and
|
||
|
|
for applications wanting to use those registers for special purposes. In these
|
||
|
|
cases the only suggestion currently is to build GMP with
|
||
|
|
<samp>--disable-assembly</samp> to avoid the assembly code.

<p><code>/usr/bin/m4</code> lacks various features needed to process <samp>.asm</samp>

<p>If the CPU selected has MMX code but the assembler doesn’t support it, a

warning is given and non-MMX code is used instead. This will be an inferior
|
||
|
|
build, since the MMX code that’s present is there because it’s faster than the

|
corresponding plain integer code. The same applies to SSE2.

<p>Old versions of ‘<samp>gas</samp>’ don’t support MMX instructions, in particular

version 1.92.3 that comes with FreeBSD 2.2.8 or the more recent OpenBSD 3.1
|

doesn’t.

</p>
|
||
|
|
<p>Solaris 2.6 and 2.7 <code>as</code> generate incorrect object code for register
|

|
|
to register <code>movq</code> instructions, and so can’t be used for MMX code.
|
||
|
|
Install a recent <code>gas</code> if MMX code is wanted on these systems.
