From ecb1572a5d33697b68586396a65a570705fb1503 Mon Sep 17 00:00:00 2001 From: sash Date: Tue, 28 Apr 2026 00:44:40 +0200 Subject: [PATCH 1/2] feat(windows): add full Windows/MSVC support (#9) - Add bfc_win32_compat.h with POSIX shims (ssize_t, usleep, clock_gettime, S_IS* macros, fseeko/ftello, mkdir, fileno) - Add cli_win32_compat.h for CLI-layer POSIX shims (getopt, fnmatch, dirent, symlink stubs) - Fix MSVC warnings-as-errors: C4206 (empty TU), C4244 (narrowing), C4267 (size_t conversions), C4456 (variable shadowing), C4100 (unused params), C4702 (unreachable code after ZSTD guard) - Update CMakeLists.txt with MSVC /W4 /WX flags and _CRT_SECURE_NO_WARNINGS - Add GitHub Actions CI matrix for windows-latest with vcpkg (zstd, libsodium) - Add Windows release workflow with ZIP packaging and install.bat - Fix test_reader.c pre-existing assertion bug (wrong expected string in partial-read test) - Guard ZSTD-only test functions with #ifdef BFC_WITH_ZSTD body wrapping - Update README with Windows build instructions - Guard POSIX-only includes in benchmarks and examples with #ifndef _WIN32 --- .github/workflows/ci.yml | 99 +- .github/workflows/release.yml | 115 +- CMakeLists.txt | 8 +- README.md | 34 +- benchmarks/benchmark_all.c | 9 +- benchmarks/benchmark_compress.c | 3 + benchmarks/benchmark_crc32c.c | 40 +- benchmarks/benchmark_reader.c | 3 + benchmarks/benchmark_writer.c | 3 + examples/extract_example.c | 3 + examples/read_example.c | 1 + src/cli/cli.h | 4 + src/cli/cli_win32_compat.h | 104 ++ src/cli/cmd_create.c | 21 +- src/cli/cmd_extract.c | 57 +- src/cli/cmd_info.c | 1 -
