Module compile 

Package C/C++ code compilation — Makevars parser and compiler invocation.

Compiles package src/*.{c,cpp,cc,cxx} files into a shared library (.so/.dylib). Uses the cc crate for compiler detection and flag management (respects CC, CXX, CFLAGS, CXXFLAGS env vars, handles cross-compilation). Only the final linking step uses std::process::Command.

Reads src/Makevars for package-specific flags.

Structs

Makevars

Parsed Makevars key-value pairs.

Enums

AssignOp 🔒

Functions

compile_package

Compile C/C++ source files in a package’s src/ directory into a shared library.

compile_package_with_deps

Compile package native code with additional include paths from LinkingTo dependencies.

current_target_triple 🔒

Get the current platform’s target triple (e.g. “aarch64-apple-darwin”).

dylib_ext 🔒

Shared library extension for the current platform.

emulate_configure 🔒

Emulate configure scripts for known packages that need platform-specific config.h or Makevars generation. Called before Makevars parsing.

emulate_configure_fs 🔒

Generate Makevars for fs package using system libuv instead of bundled.

emulate_configure_ps 🔒

Generate config.h and Makevars for the ps package.

emulate_configure_system_lib 🔒

Generic configure emulation: replace a bundled static lib build with system library found via pkg-config. Writes a Makevars that uses system headers and libs instead of bundled source.

expand_make_vars 🔒

Expand Make variable references $(VAR) with known R values. Unknown variables are stripped (removed from the string).

extract_pkg_config_name_from_configure 🔒

Parse a configure script to extract the pkg-config library name. Looks for PKG_CONFIG_NAME="..." pattern.

find_sources 🔒

Find C and C++ source files to compile.

is_valid_makevars_key 🔒

Check if a string is a valid Makevars variable name.

parse_assignment 🔒

Parse a line as KEY = VALUE or KEY += VALUE. Returns (key, op, value_part) where value_part may have trailing \.

pkg_config_name_for_package 🔒

Known mappings from CRAN package names to their pkg-config library names. Derived from the PKG_CONFIG_NAME variable in each package’s configure script.

resolve_anticonf 🔒

Resolve @cflags@ and @libs@ placeholders in a Makevars.in file by querying pkg-config, replicating R’s “anticonf” configure pattern.

shell_split 🔒

Simple shell-like splitting of a string into words. Handles basic quoting (double quotes) but not single quotes or escapes.

strip_continuation 🔒

Strip trailing backslash continuation. Returns (line_without_backslash, has_continuation).
