.check_and_compile_TMB_code: Check and Compile TMB Model Code with Persistent Cache

Description

This utility function verifies whether the TMB model shared object (.so/.dll) file has already been compiled for a specified DLL name. If not, it compiles the corresponding C++ file and caches it in a persistent directory across R sessions.

Usage

.check_and_compile_TMB_code(
  dll_name,
  pkg_name = "gkwreg",
  force_recompile = FALSE,
  verbose = FALSE
)

Value

Returns (invisibly) a list with information about the compiled model, including path, normalized path, name, and compilation status. If any step fails, an error is thrown.

Arguments

dll_name

A character string specifying the base name of the C++ file and the resulting DLL. The function assumes the code file is dll_name.cpp located in the inst/tmb/ directory of the package.

pkg_name

A character string specifying the package name. Defaults to "gkwreg".

force_recompile

Logical; if TRUE, forces recompilation even if a valid compiled file exists (default is FALSE).

verbose

Logical; if TRUE, prints detailed status messages (default is TRUE).

Details

The function works through the following steps:

1. Creates a persistent cache directory for storing compiled TMB models.

2. Checks if a compiled file for the specified DLL already exists in the cache directory and whether it's up-to-date compared to the source code.

3. If a valid compiled file exists, it loads it directly.

4. If not, the function locates the corresponding C++ file inside the package, compiles it, and stores the result in the cache directory.

5. Provides diagnostic messages regarding compilation status and exported symbols.
