Page 12 Computer Languages for Engineering - SS 131.6 The MinGW PackageThe MinGW package is a porting of the development tools which are by standard available on theLinux/Unix platform. It’s no longer necessary to use a Linux emulating layer like cygwin 8 . MinGWcontents above all compilers, a linker, a debugger and a make utility. There is no IDE available withinthe MinGW package. That means if you want to use the pure MinGW package to develop applicationsyou have to start the tool-chain manually. Because some of the tools are spawning other tools as helperapplication you have setup the correct path access to the MinGW binary folder.If we want to use the MinGW tools from the console window, we have to setup the correct path access.This is shown in figure 1.7. The MinGW binary folder is chained to the actual search path. There area lot of compiler options which are supported by the MinGW compilers. Unfortunately there is no helppage starting the compiler with the usual help option. So you have to read the manual or download somehelping informations.Figure 1.7: Setup MinGW Path AccessIf we want to compile FORTRAN sources, we can use the G77 or the GFortran compiler. The GFortrancompiler is the successor of the G77 and supports also the newer FORTRAN languages, FORTRAN 90,FORTRAN 95 and FORTRAN 2003 and parts of FORTRAN 2008.Figure 1.8 shows a simple compiler call of the GFortran compiler, which compiles the FORTRAN sourcefile and links it with the used libraries. After having called the compiler, we check the existents of theexecutable with a dir call. Then the executable is called and prints it’s legendary hello world to thescreen. The most simple call of the compiler is shown in figure 1.8. The file hello.f is selected by theinput filter *.f. The output file is set by the option -o.Figure 1.8: Create an Executable with one Compiler Call8 More information about cygwin is available on the project site http://www.cygwin.com/.E. Baeck
