1/4/2023 0 Comments How to compile simply fortranA single source file, also called a compilation unit, may contain any number of procedures (main program, subroutine, function, block data, module, and so on). The Fortran compilers will accept multiple source files on the command line. n files are dynamic libraries.įortran 90 free-format is described in Appendix C of this manual. Pass names of libraries to the linker.a files are static libraries. (Template files are special assembler files see the inline(1) man page.) The compiler will use templates to expand inline calls to selected routines. Process template files for inline expansion. o suffix.Īpply the Fortran (or C) preprocessor to the Fortran 77 source file before compilation.Īpply the Fortran (or C) preprocessor to the Fortran 90 free-format source file before Fortran compiles it.Īssemble source files with the assembler.Īpply the C preprocessor to the assembler source file before assembling it. Table 2-1 File Name Suffixes Recognized by SunĬompile Fortran source files, put object files in current directory default name of object file is that of the source but with. File names with a suffix extension other than one of those listed below, or without an extension, are passed to the linker. The suffix extension attached to file names appearing on the command-line determine how the compiler will process the file. o files are generated for those source files with errors, and no executable program is written Command-Line File Name Conventions If the compilation fails, you will receive a message for each error. This convention permits easy relinking and recompilation of files. In the previous example, the compiler will automatically generate the loader object files, growth.o and fft.o, and then invoke the system linker to create the executable program on the file growth.Īfter compilation, the object files, growth.o and fft.o, will remain. In the example below, f90 is used to compile two source files to produce an executable file named growth with runtime debugging enabled: F90 extension are "free-format" Fortran 90 source files recognized only by the f90 compiler.) for options is one or more of the compiler option flags. is one or more Fortran source file names ending in. invokes the Fortran 77 compilerį90 files. The syntax of a simple compiler command invoked at a shell prompt is: f77 files.
