Download & startup File transfer, compilation, program execution

To use the Metric programs, proceed as follows:

• Save one archive file:
  metric_unix.zip  (UNIX, Linux) or
  metric_dos.zip  (MS-DOS, Windows).
  The files differ with respect to the end-of-line characters only.
   
• Uncompress the archive:
  unzip metric_unix.zip (UNIX, Linux) or
  pkzip -extr -dir metric_dos.zip (MS-DOS, Windows...)
  will do (The files have been compressed using the utility zip on a PC running Linux). This should create a directory Metric containing the C++ mode solver library files, a makefile, and a folder Apps with some examples for application programs, C++ main()-files.
   
• Obtain the Eigen subroutines: Download and uncompress the archive (version > 3.0.1) into a temporary directory. Adhering to the instructions of Method 1 in INSTALL, copy the entire folder Eigen (found one level below) incl. all sub-folders into the Metric directory.
   
• For a first program run, choose one of the example files from folder Apps, copy it to the Metric directory, edit it for your own needs, and save it by the name newapp.cpp. Only the file metric.h must be included into the main program; it summarizes the header files which are necessary to access the library routines.
   
• Edit the first lines of the supplied makefile according to the requirements of your compiler. The included file should work appropriately for the GNU  C++ compiler.
   
• Since the application programs will most likely produce some output files which are not to be mixed with the Metric source files, they should be executed in a separate 'production' directory. Therefore create a directory P in the folder Metric.
   
• The makefile has a primary target s, which is to be produced by compiling s.cpp. Hence the commands
  cp newapp.cpp s.cpp
  make
  cp s newapp
  or equivalents produce the executable newapp. Additionally, the new application must be transferred to folder P, and a copy of the source newapp.cpp may also be useful in P. This is what the script files mo or mo.bat do. Type
  mo newapp
  in folder Metric to compile your application program (maybe a chmod +x mo or the like is required).
   
• Start the application in folder P:
  cd P
  newapp.
  The stderr output channel receives the log information: analysis parameters, structure definition, progress, propagation constant values, and notes about file input/output. Therefore you might wish to collect this information:
  newapp 2>res.
