@mauritiusdadd same issue here with the check error. Adding the flag skipped the errors. For those that use YAY:

yay -S --mflags="--nocheck" calculix

@Kassar i'm not sure why those two tests are failing... I'll try to rebuild the package myself and see if I have the same problem, meanwhile you can skip the check phase passing the --nocheck option to makepkg and try to use your compiled package

I would like to use Calulix with FreeCAD but sofar was not successful with the build process. And troubleshooting this is a bit out of my league...

After running makepkg everything including the build process is completed, but in the checks two erros occur:

...
  -> testing mass2
deviation in file mass2.dat
line: 17 reference value: 2.692186e+12 value: 2.704399e+12 
        absolute error: 1.221300e+10 
        largest value within same block: 2.692186e+12 
        relative error w.r.t. largest value within same block: 0.453646 %
...
-> testing multistage
==> WARNUNG: The data file generated by ccx is not valid
deviation in file multistage.dat
line: 1511 reference value: 2.852794e-05 value: 1.677286e-04 
        absolute error: 1.392007e-04 
        largest value within same block: 3.723345e-05 
        relative error w.r.t. largest value within same block: 373.859151 %

This causes the process to be canceled. Can I just ignore these errors and try to work with my compiled version or should I be worried?

Im on 5.9.16-1-MANJARO x86_64 with everything up to date from the core repos.

@Sinasta, I cannot reproduce your error as spooles seems to build fine on my machine and it builds fine also in a clean chroot. Please, make sure your system is fully updated and try to build the package using makepkg directly. You should also check your CFLAGS variable.

getting this error when trying to build spooles:

cc1: some warnings being treated as errors make[3]: [makeG:30: iohb.o] Error 1 make[3]: Leaving directory '/var/tmp/pamac-build-sinasta/spooles/src/spooles/Utilities/src' make[2]: [makefile:31: makeLib] Error 2 make[2]: Leaving directory '/var/tmp/pamac-build-sinasta/spooles/src/spooles/Utilities/src' make[1]: [makefile:5: lib] Error 2 make[1]: Leaving directory '/var/tmp/pamac-build-sinasta/spooles/src/spooles/Utilities' make: [makefile:123: lib] Error 2 ==> ERROR: A failure occurred in build().

Just started using CCX again this week. So far no issues. Still interested in the advanced solvers, as I need to speed up my calculations. So please let me know if you managed to build it using Pastix!

And thanks for the work you do on the PKGBUILD, it would be too difficult for my basic knowledge to build it by myself!

mauritiusdadd commented on 2020-12-08 08:22

@eBDBaF @blixawillbargeld I updated the PKGBUILD, please let me know if there is any issue.

@blixawillbargeld No, i haven't tryed Pastix solver yet but I think will start to play with it in the near future

blixawillbargeld commented on 2020-12-01 13:48

@eBDBaF @mauritiusdadd thank you! Looking forward to the updated PKGBUILD than for the next project. On a sidenote: Anyone got it running with Pastix solver already?

mauritiusdadd commented on 2020-12-01 08:53

@eBDBaF thank you for pointing that out! I'll take a look at it as soon as possible

@blixawillbargeld @mauritiusdadd With the current PKGBUILD only "symmetric stiffness/mass contributions" is calculated using multithreading in static analysis with spooles. The AUR Package spooles is compiled for MT. Adding -DUSE_MT to the CFLAGS in the Makefile of calculix enables multithreading for "Factoring the system of equations" with SPOOLES solver referring to http://www.dhondt.de/ccx_2.17.README.INSTALL Successfully tested with changed PKGBUILD and the following notice:

at execution time the environment variable OMP_NUM_THREADS must have been set to the number of CPUs you want to use. In Linux this can be done by ``export OMP_NUM_THREADS=n'' on the command line, where n is the number of CPUs. Default is 1. Alternatively, you can set the number of CPUs using the environment variable CCX_NPROC_EQUATION_SOLVER. If both are set, the latter takes precedence.
