ldc

All D packages depend on ldc to build, so every package must have ldc as BuildRequires. In addition, the ldc package includes some useful macros for D packages.

Compiler options

%{_d_optflags} must be used with ldc (normal %{optflags} do not apply to ldc, only to gcc).

%{_d_optflags} is defined as:

-release -w -g -O2

-release disables asserts, invariants, contracts and boundscheck + -w enables warnings + -g generates debug information + -O2 is the optimisation level

Some D packages use Makefiles, which usually use the $DFLAGS variable in the same way that C packages with Makefiles use $CFLAGS. In this case, export DFLAGS="%{_d_optflags}" is usually appropriate. In other cases, the build script in the D package has an option to pass in %{_d_optflags}. It is the responsibility of the packager to ensure that %{_d_optflags} are used with ldc when the package is built.

Header Files

D packages contain header files, which end with .d or .di. These header files must be installed into %{_d_includedir}/%{name}.

%{_d_includedir} is defined as:

/usr/include/d/

Libraries

At this time, Linux does not support shared libraries for D code (only OSX does). As a result, D packages are explicitly excluded from the restrictions against packaging static libraries.

To build static libraries in D, you use the same tools that you would for C, specifically, ar, ranlib, and strip.

If your D package contains static libraries, you must disable debuginfo generation, by adding this line to the top of your spec file:

%global debug_package %{nil}

Otherwise, it would generate an empty debuginfo package.

All static libraries must be placed in the *-devel subpackage. When doing this, you must also have Provides: %{name}-static = %{version}-%{release} in the devel package definition.

It is possible that this will leave the root package empty, if this is the case, do not list a %files section for the root package, only for the -devel package. This is illustrated in the example template below.
