2.6 Compilation
</H2>
<P>
The compiled codes can run with any input: almost all variables are
dinamically allocated at run time. Only a few variables have fixed
dimensions, set in file <TT>Modules/parameters.f90</TT>:
<PRE>
ntypx = 10, &! max number of different types of atom
npsx = ntypx, &! max number of different PPs (obsolete)
nsx = ntypx, &! max number of atomic species (CP)
npk = 40000, &! max number of k-points
lmaxx = 3, &! max non local angular momentum (l=0 to lmaxx)
lqmax= 2*lmaxx+1 ! max number of angular momenta of Q
</PRE>
These values should work for the vast majority of cases. In case you need
more atomic types or more k-points, edit this file and recompile.
<P>
At your choice, you may compile the complete Q<SMALL>UANTUM </SMALL>ESPRESSO suite of programs
(with <TT>make all</TT>), or only some specific programs.
All executables are linked in main <TT>bin</TT> directory.
<P>
<TT>make</TT> with no arguments yields a list of valid compilation targets:
<UL>
<LI><TT>make pw</TT> self-consistent-field package <TT>PWscf</TT>
</LI>
<LI><TT>make cp</TT> Car-Parrinello package <TT>CP</TT>

</LI>
<LI><TT>make all</TT> all of the above
</LI>
<LI><TT>make epw</TT> package <TT>EPW</TT> - prerequisite
package <TT>wannier90</TT> is compiled as well
</LI>
<LI><TT>make w90</TT> downloads <TT>wannier90</TT>, unpacks it, copies an appropriate
<TT>make.inc</TT> file, produces all executables
in <TT>W90/wannier90.x</TT> and in <TT>bin/</TT>
</LI>
<LI><TT>make want</TT> downloads <TT>WanT</TT>, unpacks it, runs its
<TT>configure</TT>,
produces all executables for <TT>WanT</TT> in
<TT>WANT/bin</TT>.
</LI>
<LI><TT>make yambo</TT> downloads <TT>yambo</TT>,
unpacks it, runs its <TT>configure</TT>,
produces all <TT>yambo</TT> executables in
<TT>YAMBO/bin</TT>
</LI>
<LI><TT>make gipaw</TT> downloads <TT>GIPAW</TT>,
unpacks it, runs its <TT>configure</TT>,
produces all <TT>GIPAW</TT> executables in
<TT>GIPAW/bin</TT> and in main <TT>bin</TT> directory.
</LI>
<LI><TT>make plumed</TT> unpacks <TT>PLUMED</TT>, patches several routines
in <TT>PW/</TT>, <TT>CPV/</TT> and <TT>clib/</TT>,
recompiles <TT>PWscf</TT> and <TT>CP</TT> with <TT>PLUMED</TT>
support
</LI>
</UL>
For the setup of the GUI, refer to the <TT>PWgui-X.Y.Z /INSTALL</TT> file, where
X.Y.Z stands for the version number of the GUI (should be the same as the
general version number). If you are using sources from the git repository, see
the <TT>GUI/README</TT> file instead.
<P>
If <TT>make</TT> refuses for some reason to download additional
packages, manually download them into subdirectory
<TT>archive/</TT>, <EM>not</EM> unpacking or uncompressing them,
and try <TT>make</TT> again. Also see Sec.(<A HREF="node8.html#SubSec:Download">2.1</A>).
