ragel-build.md

Build Windows 64-bit ragel executable

Use MSYS2 and UCRT64 environment. Existing ragel is required. We use existing package from UCRT64 that depends on libgcc, libstdc++ and libwinpthread.

pacman -S --needed autotools git mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-ragel

Fetch http://www.colm.net/files/kelbt/kelbt-0.16.tar.gz as prerequisite. Also included in gist on GitHub.

tar xf kelbt-0.16.tar.gz
cd kelbt-0.16
./configure
make -j
make install-exec

Fetch version 6.10 of ragel. THIS MUST DONE IN MINGW64 environment.

git -c core.eol=lf -c core.autocrlf=false clone -b ragel-6.10 https://github.com/adrian-thurston/ragel.git

Autoconf sources are quite old, run autoupdate before autogen.sh. We only build the binary. Examples build would fail on absence of demonstration language installed.

autoupdate
./autogen.sh
LDFLAGS="--static" ./configure --disable-manual
make -j

Verify this is a static binary

ldd ./ragel/ragel.exe
