Links to Precompiled GMP-ECM versions

[ATH]

Sorry I always forget to consider which dll files are needed with the binaries. I added libwinpthread-1.dll to the zip files.

Anyone willing to supply the latest linux binaries please?

Had issues while making ecm-params.
The file README.gpu is still missing.
I had to look bk to the configure files to find the -enable_gpu parameter.

I recommend that you get the svn version.

I found the rc1 in the inria forge, and still no README.gpu

I will recheck, maybe I did something wrong...

I meant to get svn checkout https://scm.gforge.inria.fr/anonscm/svn/ecm/ SVN repository direct from inria. Thereafter svn update will keep you on the bleeding edge.

Good luck!

Anyone have a foolproof way of compiling this version of the software? I'm trying to compile it on my i7 5820K with Windows. I have tried Cygwin64, mingw64 and Visual Studio and I receive different errors on each program.

I've even tried the SVN latest version.

I'm open to suggestions since I've never had trouble compiling a program before and I've been working on this for over a week now.

Thanks,


John

It is easy to compile once you have your environment set up for it. Since you didn't say what you've tried specifically, or what errors you ran into, I'll give you a run down based on how I compile GMP and GMP-ECM.

First, you'll need MSYS. I get the one from here:
https://sourceforge.net/projects/min...nary-packages/
The current latest is from 2013-05-15, and is called msys+7za+wget+svn+git+mercurial+cvs-rev13.7z
I then extract that to:
c:\msys\msys-20130515\

Then you'll need mingw64. You can get that here:
https://sourceforge.net/projects/min.../mingw-builds/
Choose which compiler version you want, the latest is 4.8.5, 4.9.3, or 5.3.0. Probably go with 4.9.3, unless you want 5.3.0. Then choose "threads-posix", then choose "seh", then download the latest available. Once I've done that I extract it to:
c:\mingw64\mingw64-4.9.3-20150903\

Then, go back into the msys folder and edit the following file:
c:\msys\msys-20130515\etc\profile
to change:

if [ $MSYSTEM == MINGW32 ]; then
  export PATH=".:/usr/local/bin:/mingw/bin:/bin:$PATH"

to this:

if [ $MSYSTEM == MINGW32 ]; then
#    export PATH=".:/usr/local/bin:/mingw/bin:/bin:$PATH"
  export PATH=".:/c/mingw64/mingw64-4.9.3-20150903/bin:/usr/local/bin:/bin:$PATH"

Then, download the latest GMP from https://gmplib.org/ The current latest is 6.1.0.
Open up an msys shell by double clicking the c:\msys\msys-20130515\msys.bat file. Let's say you extracted GMP to c:\gmp\gmp-6.1.0\, then in the msys shell, you would run the following commands:
cd /c/gmp/gmp-6.1.0/
./configure
make
make check

If all of that completes successfully, then you need to copy two files:
1) copy gmp.h from c:\gmp\gmp-6.1.0\ to c:\mingw64\mingw64-4.9.3-20150903\x86_64-w64-mingw32\include\
2) copy libgmp.a from c:\gmp\gmp-6.1.0\.libs\ to c:\mingw64\mingw64-4.9.3-20150903\x86_64-w64-mingw32\lib\

Now you have msys, mingw64, and gmp set up correctly. To get gmp-ecm compiled, download the latest svn, let's say you save those files to:
c:\gmp-ecm\svn_2915\
Then, in the msys shell, you would:
cd /c/gmp-ecm/svn_2915/
autoreconf -i
./configure --enable-asm-redc --build=x86_64-w64-mingw32 --disable-assert
make
make check

This should all complete successfully for you. If you run into any errors, let us know and we can try to help you resolve them. If you don't run into any errors, then you will have a working ecm.exe file that you can use to factor numbers!

The latest, as of last night, is SVN 2916 and it works well for me. Note that 2914 and below have a serious bug in the GPU portion of GMP-ECM.

I would (and did last night)also run make ecm-params between make and make check for (near) optimal performance.

It builds fine for me with Visual Studio 2013 and CUDA 7.5 (for the GPU build). It won't build with Visual Studio 2015 at the moment becasuse NVIDIA has yet to update its CUDA toolkit to work with this compiler.

If you can let me know what issues you ran into in using the Visual Studio build, I might be able to help.
