Notes about leparagliding.f compilation
For use LEparagliding you do not need to compile the source code.
This is optional. This information is only useful to who want to or
need to compile the code. The file leparagliding.f contains all the
source code for leparagliding. Compilation is the process through which an executable program is generated from the source code. Compiling yourself, the source code, ensures total compatibility with your computer. LEparagliding may be compiled easyly in GNU/Linux, Windows, and MAC.
CASE 1) COMPILATION IN GNU/Linux, the easy way...!
The source code is the file named leparagliding.f
You will need a compiler GNU Fortran. You will need a compiler GNU
Fortran. It is recommended that you install (apt-get) the following
f77, fort77, gfortran, gfortran-8, f2c, gcc, gcc-fortran
apt-get f77, fort77, gfortran, gfortran-8, f2c, gcc, gcc-fortran
source code writing in the console some of these instructions (depends on your system):
gfortran-8 -std=legacy leparagliding.f
f77 -Nn1604 leparagliding.f
(or similar compiling instructions)
Run the program:
To set permissions, if necessary type: chmod 755 a.out
Put the executable file a.out inside a lep
folder containg all the paraglider files (leparagliding.txt,
airfoil1.txt, airfoil2.txt,...) and execute writing:
If you want, you can rename the executables file a.out as lep-3.XX.out or other name.
In the latest versions of LEparagliding (3.12) I'm using the gfortran compiler with success. Only some warning messages.
CASE 2) COMPILATION IN WINDOWS
Install the Cygwin console in your system. When installing Cygwin be sure to select and install all Fortran related packages: gcc, gcc-fortran, f77 (or g77), gfortran, gfortran-8, f2c, fort77, gcc, gcc-fortran... Open the
cygwin console, and move to the lep folder containing leparagliding.f
and all your paraglider files (leparagliding.txt, airfoil.txt,...). Latest versions of leparagliding compiles well using gfortran, f77 -Nn1694, fort77 -Nn1604
Open yours Cygwing console. Move to the lep folder (use UNIX commands
cd, cd .., ...). Compile using gfortran, gfortran-8, f77, or fort77 exactly as in Linux:
f77 -Nn1604 leparagliding.f
(Optionally rename a.exe tot lep-3.XX-win.exe or similar name)
you use a version compiled by yourself, no dll's are needed in the
working directory. System uses automatically the defaut dll's.
CASE 3) COMPILATION IN MAC
Read here: https://gcc.gnu.org/wiki/GFortranBinariesMacOS
Be sure you install gcc and gfortran
compile the code as in the case of Linux:
Since release lep-3.17, all the LEparagliding executables are "statically
compiled". This means that some Fortran libraries are automatically
added to the .out (Linux, OSX) and .exe (Windows) executable files. In
theory, this will help run the program on the computers of users who do
not have Fortran compilers installed. The regular user does not need to
know anything about this. If you are curious and want to know what
is the instruction used for static compilation is the following:
gfortran -static-libgfortran leparagliding.f
gfortran -static-libgfortran pre-processor.f
