This is for Mecway 18: i am trying below

4)** Compile CCX with MKL and a patch to enable Out-Of-Core (OOC) mode. The source code with step-by-step instructions is in ccx_win64_mkl_pardiso_source_2.19.zip in Mecway's install location. After compiling, set it in Mecway through Tools -> Options -> CalculiX -> Solver.

This are the detailed instructions contained in the installation folder of MECWAY.

In my case C:\Program Files\Mecway\Mecway17\ccxMecway/ccx/ccx_win64_mkl_pardiso_source_2.19.zip file


-Instructions for building the following on Windows:
64 bit CCX with SPOOLES single-threaded
64 bit CCX with MKL PARDISO multi-threaded and with Out-Of-Core mode available


1) Install MSYS2 64-bit
From https://www.msys2.org/


2) Update MSYS2
Open "MSYS2 MSYS" shell and enter this command
pacman -Syu
Open "MSYS2 MSYS" shell again and enter this command
pacman -Sy


3) Extract this archive's ccx folder to msys64/home// so that the paths are msys64/home//ccx/src/...


4) Install tools and compile

Open "MSYS2 MSYS" shell again and enter these commands
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-gcc-libgfortran
pacman -S mingw-w64-x86_64-gcc-fortran
pacman -S msys/make
pacman -S msys/perl
cd ~/ccx/src
./build.sh


5) Find the compiled ccx.exe, ccx_MKL.exe, and their dlls in

msys64/home//ccx/src/x64/install


I'm completely newby compiling programs and it worked following carefully the instructions. I have WIN10Pro and installed from the v.16 Mecway folder.
¿Did you execute MSYS2 with admin rights?
You laptop name seems very large and has some spaces ¿isn't it?. ¿Maybe that's a problem?.

Regarding point 3 ¿did you Extract (Unzip) the ccx folder or just copy paste?
You need to unzip.

In my case it looks like this:



Check those files "cannot stat" thye are where they should

Aftab

Thanks disla for your help. Yes , i extracted those to the relevant folder and they are there, as below.

This ones too?

Aftab

no luck so far. same error.

This error

"cp: cannot stat [...] ccx_2.19': No such file or directory"

or

"cp: cannot stat [...] ccx_2.19_MKL': No such file or directory"

means the final binary failed to be built. Look in x64/buildlog.txt and you should find error messages at the end of the file buried among all the warnings and other messages.

I think it's because your home directory has spaces in its name. That's a known problem and I haven't been able to get the build script and makefiles to work properly with spaces. Please rename it. Sorry for not making this clearer.

Many Thanks Victor, removing spaces from the username sorted the issue. Much appreciated.
