Ldc2 / Compile Source Without Linking
Compile Source Without Linking
Compile D source files into object files without linking.
ldc2 -c <path/to/source.d> ldc2 -c <path/to/source.d> #!/bin/bash
# Compile Source Without Linking
ldc2 -c {{path/to/source.d}} import subprocess
# Compile Source Without Linking
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"ldc2",
"-c",
"<path/to/source.d>"
]
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.")
if __name__ == "__main__":
run_command() When To Use
When building modular code and dependencies are resolved separately for linking later.
Pro Tip
Ensure the object files generated are placed in a known directory for efficient linking later.
Command Builder
Tune the command before you copy it
ldc2 -c <path/to/source.d> Anatomy of Output
Understanding the result
Compiling /path/to/source.d without linking... Compilation Start Indicates the start of compilation for an object file.
Created object file: /path/to/source.o Output Confirmation Confirms object file was generated successfully.
Total time: 32 seconds Compile Duration Time taken to complete compilation.
Power User Variants
Optimized versions
ldc2 -c path/to/source.d -g Generate debug symbols while compiling.
ldc2 -c path/to/source.d -Ofast Compile with optimizations but without linking.
Unix Pipeline
Shell combinations
ldc2 -c path/to/source.d -o object_file.o Specify output object file name directly.
Troubleshooting
Common pitfalls
Error: cannot find source file.
Solution: Verify the file path is accurate.
Error: Unsupported source file type.
Solution: Ensure the source file has a valid .d extension.
Error: Internal compiler error.
Solution: Check compiler version or run with verbose logging for additional details.
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.
-
-c - Command Option
- Tool-specific option used by this command invocation.
