h1. Building 

 Quick build 

 *For guide for users on 100% compatible systems* systems 

 We assume that you have successfully [[downloaded]] %{color:red}alter Link nach sxlib =:% "downloaded":http://sxlib.mpie.de/wiki/Download    and unpacked the package. package, possibly including [[3rd-party packages]] %{color:red}alter Link nach sxlib =:% "3rd-party packages":http://sxlib.mpie.de/wiki/Download#third-party in sphinx/sxaccelerate/3rd-party/packages/ . 

 Please make sure that CPU throttling is deactivated when compiling (specifically: ATLAS!). 

 <pre> 
    cd sphinx 
    ./setup 
    ./configure --disable-debug 
    make all 
    make install 
 </pre> 


 If this does not work, please read the rest of this page. 

 You may want to run the [[testbed]] after compilation.

 Please make sure that CPU throttling is deactivated when compiling the third-party libraries (specifically: ATLAS!).  

 h1. Building 

 Depending on the scope of your work with S/PHI/nX please choose the best fitting building approach: 
 | | Users | Testers | Developers | 
 | build S/PHI/nX release |once | once | frequently | 
 | build S/PHI/nX debug | | once | frequently| 
 | build SxAccelerate | | | once - frequently | 
 | build numlibs | | | once - rarely | 

    * On machines with N CPUs: you may use parallel make via make -j 2N  

 h2. configure options (selection) 

 | --disable-atlas    --disable-lapack    --enable-mkl    --with-mklpath=... | use MKL for BLAS/LAPACK (support for selected versions) |  	
 | --disable-atlas    --disable-lapack    --enable-acml | use ACML for BLAS/LAPACK | 
 | --enable-mpi | compile MPI version (experimental) | 
 | --enable-openmp | compile using openmp, try to use openmp numerical libraries (experimental) | 
 | --with-numlibs=... | all external numerical libraries can be found in these paths (/path/1/:/path/2/:/path/3/) | 
 | --without-numlibs | external numerical libraries can be found in standard paths or via specified LDFLAGS and CPPFLAGS | 
 | CXX=... | set C++ compiler | 
 | CXXFLAGS=... | set additional C++ compiler flags | 
 | LDFLAGS=... | set additional linker flags (see compiler/linker docu) | 
 |CPPFLAGS=... | set additional preparser flags (see compiler docu) | 
 |CPPFLAGS='-I...' | set additional search path for external includes    | 


 h2. S/PHI/nX users 

 (Build S/PHI/nX only once to create an optimized executable.) 

     # cd sphinx 
     # ./setup 
     # ./configure --disable-debug --prefix=/instpath/to/sphinx 
     # make all install  

 If --prefix=/instpath/to/sphinx is omitted, SPHInX will be installed into the current directory. 

 h2. S/PHI/nX test users 

 (Build S/PHI/nX in debug and release only once to create an optimized executable as well as a version that can generate a memory core file.) 

     # cd sphinx 
     # ./setup 
     # ./configure --prefix=/instpath/to/sphinx --with-debug --with-release 
     # make all install  

 Read more about [[being a S/PHI/nX alpha tester]]. 

 h2. S/PHI/nX developers 

 (Suitable for developers) 


 h2. Easy build instructions 

     * As a simple alternative, you may use the build instruction for test users. 
     * Properly configured build directories for debug and release mode will be found as subdirectories in sphinx/sxaccelerate/ and sphinx/, respectively. 
     * While developing, there is no need to install (make all install -> make all). 
     * You can compile all build directories by a top-level make, ... 
     * ... but also each build directory separately (but beware: when changes are made in sxaccelerate, you typically need to rebuild sxaccelerate first, and then sphinx!). 
     * For developers, we recommend to build the external libraries separately, as described in the following. Precompiled numlibs avoid repeated installation of the numlibs when top-level make is invoked, and can be reused for concurrent SPHInX versions. 
     * use parallel make (make -j ...) 
     *use top-level sxmake wrapper instead of make  


 h2. Advanced build instructions 

 p(. 1. cd sphinx 
     2. ./setup 
     3. Possibly switch to a separate build directory (on a local file system) 

 <pre> 
     mkdir -p /build/path/sphinx 
     mkdir -p /build/path/sphinx/sxaccelerate/3rd-party 
     cd /build/path/sphinx 
 </pre> 

 p(. If a build path is used, replace ./configure by the corresponding absolute filenames to the configure scripts in the source tree. 
    
 p(. 4. Building 3rd-party numeric libraries 

      # cd sxaccelerate/3rd-party 
      # ./configure --prefix=/instpath/to/numlibs 
           where /instpath/to/numlibs refers to the folder where the compiled libraries will be installed in. 
      # make all install 
      # cd ../.. 
      # optionally clean up: 
           rm -rf sxaccelerate/3rd-party  

 p(. If --prefix=/instpath/to/numlibs is omitted, numlibs will be installed in sxaccelerate/3rd-party (NO CLEANUP!) 

 p(. 5. Compile S/PHI/nX 

         # ./setup 
         # ./configure --prefix=/instpath/to/sphinx --with-debug --with-release --with-numlibs=/instpath/to/numlibs 
         # where /instpath/to/sxaccelerate is where the libraries and headers will be installed to. 
         # make  

 h2. S/PHI/nX core developers 

 (Suitable only for freaks) 

 h2. More configure options 

 | --enable-debug | compile in debug mode (default) | 
 | --disable-debug | compile in release mode | 
 | --enable-shared/--disable-shared | enable/disable shared objects/linkage (default: enable) | 
 | --enable-static/--disable-static | enable/disable static objects/linkage (default: disable) | 
 | --enable-numlibschecks | check the numlibs install | 


 h2. Advanced build instructions 

 p(. 1. Call ./setup in /src/path/to/sphinx 
     2. Build 3rd-party numeric libraries (see instructions for developers) 
     3. Building sxaccelerate 

 <pre> 
    mkdir -p /build/path/sxaccelerate 
    cd /build/path/sxaccelerate 
    /src/path/to/sphinx/sxaccelerate/src/configure [options] --with-numlibs=/instpath/to/numlibs 
 </pre> 

 p(. For available configure options, see configure --help. You may build debug and release versions side by side using the sxaccelerate/configure --with-debug --with-release - note the omission of the src before the configure in this case!  

 p(. 4. Building sphinx on top of an existing sxaccelerate build (or install) 

 <pre> 
     mkdir -p /build/path/sphinx 
     cd /build/path/sphinx 
     /src/path/to/sphinx/src/configure --with-sxaccelerate=/build/path/sxaccelerate 
 </pre> 

 Note that ==*you cannot override any configure options set in the sxaccelerate*== that affect compiler/linker flags or numlibs selection.
