LIBRESECT

This is an elaborate Pure C™ wrapper over libclang with almost no runtime dependencies and simplified ABI tailored for extracting information from C/C++ headers to create bindings to C/C++ libraries.

The goal is to return binary-compatible metadata that can be used to invoke C/C++ routines from statically or dynamically linked libraries. There's no guarantee this library would keep all types intact as they specified in a header. They might be converted to their canonical representations in some cases.

ВНИМАНИЕ

It's a work-in-progress library. Neither binary-level nor source-level compatibility is guaranteed yet.

Building

Prepare your disk and RAM - we need to build a custom LLVM dist until I push required libclang additions into upstream.

Windows

Prerequisites

choco install -y ninja git cmake gnuwin python3
pip3 install psutil

For x64 arch you will need to use this powershell target

# adapt to your version of VS
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -noe -c "&{Import-Module """C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\Microsoft.VisualStudio.DevShell.dll"""; Enter-VsDevShell 0c759dbc -DevCmdArguments '-arch=x64'}"

LLVM

# getting LLVM sources
git submodule update --init --recursive
# building LLVM and static libclang bundle, going for a walk
./build_clang.sh

libresect

Then we can build resect using usual cmake magic:

mkdir -p build/resect/ && cd build/resect/
cmake -DCMAKE_BUILD_TYPE=Release ../../ && cmake --build .

Valgrind check

valgrind --suppressions=../valgrind.sup --leak-check=full --show-leak-kinds=all --read-var-info=yes --track-origins=yes --log-file=valgrind-out.txt ./resect-test "/path/to/header.h"
