Compiling YAFU for Windows using mingw

[swellman]

Why not just download a Windows executable? Many to choose from.

You will likely also need the ggnfs sievers on your computer if you plan on having Yafu perform NFS factoring. Yafu calls these executables from a location you specify.

And GMP-ECM if you want Yafu to run ECM, again from a location on your local machine which you specify.

Could anybody explain how to do? Best regards

Using mingw64 (I assume with msys2/ucrt64), build msieve with WIN=1 WIN64=1 on the make command line, e.g., make all NO_ZLIB=1 WIN=1 WIN64=1

This tells the build to omit -ldl, among other things.

ok, thanks for this, iappreciate. But now:
$ make -f Makefile.mingw x86_64 NFS=1 USE_SSE41=1
make: *** No rule to make target 'x86_64'. Stop.
include/factor.h:32:10: fatal error: zlib.h: No such file or directory

I forgot to say that I've build yafu (great piece of software!!!) in wsl-. And it works but is lame and slow compared to windows prebuild version. So my desire is to build it in windows either with msys2 or visual studio
Ciao, silvio

Haven't you tried the pre-built executables from his GitHub site?

Yes of course, but my joy and fun in to build myself!

This is strange to hear. For me, wsl is far superior to the pre-built windows version, which was made with visual studio. SIQS, ECM, and NFS should all run faster in wsl. Building with mingw is probably still possible but I stopped using it for the pre-built windows executables because there were too many little usability and build issues (pipes/redirects work slightly differently; mingw/msys2 was giving me fits) and the number of things I had to debug and test grew too large.

Oh, I see. What about a simple guide to building with Visual Studio? Anyone?
Infinite thanks

1.) Obtain Visual Studio 2022
2.) Obtain mpir 3.0, ecm (latest stable release), msieve, ytools, and ysieve source dependencies
3.) Build MPIR 3.0, ECM, msieve, ytools, and ysieve, in that order, with the best options for your processor
4.) Build yafu, editing the compiler general options to include the best instruction sets for your processor and editing the linker general options to point to the various libraries you previously compiled. Some of this is done for you already if you've arranged and named your directories correctly (all next to each other)

Thanks for this. I believe I'd need a step-by-step guide (for dummyes).

1) go to https://github.com/bbuhrow/yafu/blob...r/yafu-x64.exe
2) click "Download"
3) you now have a Visual Studio build of YAFU.
