When working with Julia, it can be helpful to include debug symbols in the sysimage from the packagecompiler jl. This allows for easier debugging and troubleshooting of code. In this article, we will explore three different ways to accomplish this task.
Option 1: Using the PackageCompiler.jl Package
The first option is to use the PackageCompiler.jl package, which provides a convenient way to compile packages and include debug symbols in the sysimage. Here is an example code snippet:
using PackageCompiler
# Compile the package with debug symbols
create_sysimage(:MyPackage, sysimage_path="path/to/sysimage.so", precompile_execution_file="path/to/precompile.jl", debug=true)
This code snippet demonstrates how to use the create_sysimage function from the PackageCompiler.jl package to compile the package with debug symbols. The :MyPackage argument specifies the package to be compiled, while the sysimage_path argument specifies the path where the sysimage file should be saved. The precompile_execution_file argument is optional and can be used to specify a file that contains code to be executed during the precompilation process. Finally, the debug argument is set to true to include debug symbols in the sysimage.
Option 2: Manually Building the Sysimage
If you prefer a more manual approach, you can build the sysimage yourself using the Julia command line interface. Here is an example code snippet:
julia --output-ji="path/to/sysimage.ji" --compile=min sysimage.jl
This code snippet demonstrates how to use the Julia command line interface to build the sysimage. The --output-ji option specifies the path where the sysimage file should be saved, while the --compile=min option specifies the level of optimization to be applied during compilation. The sysimage.jl file should contain the necessary code to precompile the package and include debug symbols.
Option 3: Using the Julia PackageCompiler Module
Another option is to use the Julia PackageCompiler module directly. Here is an example code snippet:
using PackageCompiler
# Create a sysimage builder
builder = SysimageBuilder(debug=true)
# Add packages to the sysimage
add_package!(builder, :MyPackage)
# Build the sysimage
sysimage_path = build(builder, "path/to/sysimage.so")
This code snippet demonstrates how to use the PackageCompiler module to create a sysimage builder and add packages to it. The debug argument is set to true to include debug symbols. Finally, the build function is called to build the sysimage and save it to the specified path.
After exploring these three options, it is clear that using the PackageCompiler.jl package (Option 1) provides the most convenient and straightforward way to include debug symbols in the sysimage. It offers a high level of abstraction and simplifies the process with its dedicated functions. Therefore, Option 1 is the recommended approach for including debug symbols in the sysimage from the packagecompiler jl.
