MRTKLIB v0.5.7 Release Notes

Release date: 2026-03-12 Type: Feature — Port RTKLIB convbin and str2str CLI applications Branch: feat/convbin-str2str

Overview

v0.5.7 ports the two remaining RTKLIB console applications — convbin (RINEX converter) and str2str (stream relay/converter) — into the MRTKLIB build system. Both executables are fully modernized: WIN32-specific code has been removed, POSIX-only paths are retained, and all source files have been formatted with clang-tidy (mandatory braces) and clang-format (Google style).

Changes

Added

File Description
apps/convbin/convbin.c CLI application to convert receiver binary log files to RINEX obs/nav and SBAS message files
apps/str2str/str2str.c CLI application for stream-to-stream data relay with optional format conversion
src/data/mrtk_convrnx.c Core RINEX translation logic for RTCM and receiver raw data (library module)
src/stream/mrtk_streamsvr.c Stream server functions for data relay and format conversion (library module)

Changed

File Change
CMakeLists.txt Added convbin and str2str executable targets; added mrtk_convrnx.c and mrtk_streamsvr.c to mrtklib library sources

Removed

  • WIN32 code — All #ifdef WIN32 / #ifndef WIN32 preprocessor blocks and Windows-specific includes (winsock2.h, WSAStartup, etc.) have been removed. Only POSIX (Linux/macOS) code paths are retained.
  • Constellation enable macros — #ifdef ENAGLO, ENAGAL, ENACMP, etc. guards have been removed; all constellations are unconditionally enabled.

Modernization Details

The following transformations were applied to the upstream RTKLIB source:

  1. Header includes — #include "rtklib.h" replaced with #include "mrtklib/rtklib.h" (MRTKLIB compatibility wrapper).
  2. License headers — Upstream copyright blocks replaced with MRTKLIB BSD-2-Clause license headers. Original version/history information is preserved as Doxygen docstrings (/** ... */).
  3. Code formatting — clang-tidy applied for mandatory {} on all control flow statements; clang-format applied with Google style.

Scope

5 files changed, +3,216 / -1 lines.
