-The Netgen 4.5 from the web location : http://www.hpfem.jku.at/netgen/
-(CVS access) is used in the SMESH Module of Salome3 distribution.

-1. How to build Netgen for Salome
-------------------------------
+Netgen home page: http://sourceforge.net/apps/mediawiki/netgen-mesher.
-1.1. Download Netgen 4.5 from the NETGEN home site (see above).
+1. Minimal requirements
-1.2. Unpack the downloaded Netgen 4.5 archive
- (hereafter we assume that this is netgen45 directory)
+Minimal version of Netgen required for SALOME is 4.9.13.
-1.3. Patch the netgen 4.5 distribution for SALOME:
+2. How to build Netgen for SALOME NETGEN Plugin
+-----------------------------------------
-$ cd netgen45
-$ patch -p1 < patch_directory/netgen45ForSalome.patch
+2.1. Download Netgen archive (here netgen-4.9.13.tar.gz) and unpack it
-1.4. For 64-bit platform you also need to apply another patch:
+2.2. Patch the Netgen distribution for SALOME
-$ cd netgen45
-$ patch -p1 < patch_directory/netgen45lib64.patch
+ $ cd netgen45
+ $ patch -p1 < patch_directory/netgen49ForSalome.patch
-1.5. Set CASROOT environment variable to OCCT installation path,
- since Netgen 4.5 requires Open CASCADE Technology:
+ Note that patch corresponds to the version of Netgen you use.
+ For example, netgen49ForSalome.patch mentioned above is a patch
+ file for Netgen 4.9.13. The patch for Netgen can be found in
+ NETGENPLUGIN_SRC/src/NETGEN directory.
-$ setenv CASROOT <occt_installation_path>
+2.3. Configure the netgen compilation. For example
-1.6. Compile and install netgen 4.5. To do this, simply run
- makeForSalome.sh script (it is created from the patch):
+ $ cd netgen-4.9.13
+ $ ./configure --prefix=THE_INSTALLATION_PATH \
+ --with-occ=${CASROOT} \
+ --with-tcl=${TCLHOME}/lib --with-tk=${TCLHOME}/lib \
+ --with-tclinclude=${TCLHOME}/include
-$ sh makeForSalome.sh
+ Note that Netgen depends on some products like Open CASCADE
+ Technology and Tcl/Tk. These products should be specified
+ to the configure script via options.
+2.4. Compile the netgen product
+ $ make
+ $ make install
-2. Additional information for maintainers

-
-The file check_NETGEN.m4 assumes that Netgen is installed in
-the directory <netgen_installation_path> as follow:

-prompt> ls <netgen_installation_path>/include

-prompt> ls <netgen_installation_path>/lib

-libcsg.a libgeom2d.a libla.a libnginterface.a libopti.a
-libgen.a libgprim.a libmesh.a libocc.a libstlgeom.a
-
-The library files can be also installed in the LINUX or LINUX64
-subfolder of the lib directory.
-
-All the libraries *.a should be compiled without the option -DOPENGL.
-netgen45 is assumed to be the directory downloaded from the above web
-location archive of Netgen. The library
-<netgen_installation_path>/lib/libnginterface.a should contain the objects
-nglib.o (from netgen45/libsrc/interface/nglib.cpp) and ngnewdelete.o
-(from netgen45/ngtcltk/ngnewdelete.cpp).
-
-To have that kind of distribution from the version in the above web location you
-need not to compile Netgen as suggested in the netgen45/README.INSTALL file.
-Simply modify the Makefiles to remove -DOPENGL from compiler flags
-list and to add OCC include dir and flags to compiler flags, add the objects
-nglib.o and ngnewdelete.o to the library libnginterface.a and
-recompile the libraries only.
-All this job is done by applying the patch and running the script makeForSalome.sh.
-
-The suggested patch alters some Netgen sources to compile them.

+2.5. Patch the installation directory by copying include files
+ needed by NETGEN Plugin. Use the script
+ NETGENPLUGIN_SRC/src/NETGEN/netgen_copy_include_for_salome
+ to achieve that. The first argument is the directory containing
+ the Netgen sources. The second argument is THE_INSTALLATION_PATH
