Links to Precompiled GMP-ECM versions

[kruoli]

There seems to be at least a bit of traffic at https://gmplib.org/repo/gmp/.

It says:

./gmpecmcompile: Zeile 210: tar: Kommando nicht gefunden.
./gmpecmcompile: Zeile 212: cd: /c/msys64/home/gmp-6.1.2: No such file or directory

This translates to:

./gmpecmcompile: line 210: tar: Command not found.
./gmpecmcompile: line 212: cd: /c/msys64/home/gmp-6.1.2: No such file or directory

Actually, /usr/bin does not include a tar binary.
It cannot cd since the call to tar never actually created that folder.

I'm not sure why your error is in German, I'm don't think that MSYS2 follows the Windows language?

Did you extract the file gmpecmcompile.zip with 7-zip to C:\ so the folder is called c:\msys64 ?

The file to start MSYS2 should be: C:\msys64\msys2_shell.cmd and when you start it, it should look like the screenshot. If you do a "ls -l" the tar file should be right there.

The tar file is located here: C:\msys64\home\gmp-6.1.2.tar

Could you please type which tar on your end? I have a suspicion...

It seems to do that for some reason... (see also in the screenshots):

Yes, I am using 7-zip 19.00 x64. See the screenshots, the path is correct (I actually extracted it freshly to make those screenshots).

Yes, that's not the problem. But when starting the script, it simply cannot find tar.

Indeed, see the screenshots.

Ah it was the tar program itself you were missing, I misunderstood.
I had tar.exe in my windows\system32 folder for some reason, so I did not notice it needed to be installed.

You can install it in MSYS2 with the command:
pacman -S tar

I also updated the zip file, so it is already installed.

Nice! This time, I got a working ecm.exe (if I ignore the problem with the missing libgmp-10.dll as seen previously, which I then fixed manually).

You can find libgmp-10.dll and any other needed files in the C:\msys64\mingw64\bin folder. You can add that folder to the PATH variable, or copy just that file to another folder in your PATH variable or to the folder with ecm.exe.



Anyone know why libgmp-10.dll that comes with MSYS2 is needed for MSYS2 programs? Programs still uses the GMP version you compiled yourself, you can check by making a C/C++ program printing the GMP version used:
printf("%i %i %i\n",__GNU_MP_VERSION,__GNU_MP_VERSION_MINOR,__GNU_MP_VERSION_PATCHLEVEL);

and it shows it actually uses the version you compiled yourself.

Here is even an example of a program not using GMP at all that requires libgmp-10.dll:

JIC, if anyone have 32bit static build for Linux, please share. Can't compile it by myself due to many compiler errors.

There is a 32-bit version compiled for Ivy Bridge in this post:
