Ldc2 / Compile Source To Executable

Compile Source To Executable

Compile D source code to a standalone executable file.

$
Terminal
ldc2 <path/to/source.d> -of=<path/to/output_executable>

When To Use

When preparing a D program for deployment or testing in a production-like environment.

Pro Tip

Linking issues can arise if path dependencies are not correctly specified in the environment.

Command Builder

Tune the command before you copy it

$
Generated Command
ldc2 <path/to/source.d> -of=<path/to/output_executable>

Anatomy of Output

Understanding the result

Compiling /path/to/source.d... Compilation Start

Indicates the beginning of the compilation process.

Linking /path/to/output_executable... Linking Stage

Refers to successfully linking all required libraries.

/path/to/output_executable created successfully Success Message

Confirms the output executable file was generated.

Total time: 57 seconds Compile Duration

Total compile time for the process.

Power User Variants

Optimized versions

ldc2 path/to/source.d -Ofast

Compile with optimizations turned on.

ldc2 path/to/source.d --split

Split output into multiple components.

Unix Pipeline

Shell combinations

ldc2 path/to/source.d -of=output_executable > build.log

Capture build process output in a log file.

Troubleshooting

Common pitfalls

Error: cannot open source file.

Solution: Check that the specified source path is correct and the file exists.

Error: linking failed for output_executable.

Solution: Ensure all necessary libraries are correctly linked.

Error: Unsupported version of D compiler.

Solution: Verify you are using a compatible version of the D compiler.
