It will enable the installation of mod files in parallel for multiple compilers. It will install .smod files for Fortran 2018. .Sp The fortran-mod file syntax follows dh_install: pairs of sources and optional target directories. The default directory will be \f(CW$fmoddir\fR ( /usr/lib/$multiarch/fortran/$compiler_mod_directory/) If the target directory is absolute (starts with a '/'), this directory is used in the target package. If the target does not absolute, it will be treated as a subdirectory of \f(CW$fmoddir\fR. .Sp \&\f(CW$compiler_mod_directory\fR is based on the compiler module version: currently gfortran\-mod\-15 for gfortran\-9, and flang\-mod\-34 for flang\-7. These will be updated for incompatible compiler versions. There is a symlink in \f(CW$libdir\fR/fortran/ for the 'canonical' compiler name, linking to this, e.g. /usr/lib/$multiarch/fortran/x86_64\-linux\-gnu\-gfortran\-9 \-> gfortran\-mod\-15 This enables makefile fragments to construct \f(CW$fmoddir\fR as required from : .Sp .Vb 2 \& FC:=$(shell basename $(shell readlink \-f /usr/bin/gfortran)) \& FMODDIR:=/usr/lib/$(shell dpkg\-architecture \-qDEB_HOST_MULTIARCH)/fortran/$(FC) .Ve .Sp Its not clear what happens on module version changes in Flang/F18. While the version number signifies format changes, it appears the design is currently to be backward compatible and read previous versions. Hence symlinks for flang handling may be required; however a new f18 front-end is being developed, so this may change. .RE .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBdebhelper\fR\|(7) .SH "AUTHORS" .IX Header "AUTHORS" Se\*'bastien Villemot Alastair McKinstry .PP Lots of code stolen shamelessly from dh_install (Joey Hess ).
