Ldc2 / Compile Source To Executable
Compile Source To Executable
Compile D source code to a standalone executable file.
ldc2 <path/to/source.d> -of=<path/to/output_executable> ldc2 <path/to/source.d> -of=<path/to/output_executable> #!/bin/bash
# Compile Source To Executable
ldc2 {{path/to/source.d}} -of={{path/to/output_executable}} import subprocess
# Compile Source To Executable
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"ldc2",
"<path/to/source.d>",
"-of=<path/to/output_executable>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: ldc2 not found. Please install it first.")

run_command() 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
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.
Command Breakdown
What each part is doing
-
ldc2 - Base Command
- The executable that performs this operation. Here it runs Ldc2 before the shell applies any redirect operators.
-
<path/to/source.d> - path to source.d
- The value supplied for path to source.d.
-
<path/to/output_executable> - path to output executable
- The value supplied for path to output executable.
-
-of=<path/to/output_executable> - Command Option
- Tool-specific option used by this command invocation.
