Enables building pdfalto on Windows with MSYS2/MinGW-w64, producing
a native PE64 executable without Cygwin dependency. Two files changed:
CMakeLists.txt:
- MinGW: use system libraries via pkg-config instead of vendored
static .a files (which are only built for Linux/Mac)
- Windows link libraries: ole32, uuid, ws2_32 (replacing dl/pthread)
- Conditional include directories: MinGW uses system headers for
libxml2/ICU/freetype; vendored xpdf headers still used
src/XmlAltoOutputDev.cc:
- Replaced "using namespace std;" with explicit using declarations
(17 types) to resolve std::byte conflict between GCC 15's C++17
std::byte enum and Windows SDK's byte typedef in rpcndr.h
Build instructions:
pacman -S mingw-w64-x86_64-{gcc,cmake,libxml2,zlib,libpng,freetype,icu,make}
mkdir build && cd build
cmake .. -G "MinGW Makefiles" -DNO_FONTCONFIG=ON
mingw32-make -j4
Tested: 3.9 MB PE64 binary, processes PDFs correctly with GROBID.
