@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

@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 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. Source:

The ccx manual has much more information about this topic: Page 12

Hey @mauritiusdadd , upgrading GCC seems to have fixed the problem. I'm running Manjaro and just found out that GCC is apparently one of the few packages that's treated differently in Manjaro and Arch. Had to move my system to testing repos in order to install GCC 10. Thanks for the help!!

Hi @steveo_155, is your system fully updated? In particular, do you have gcc 10?

I am getting the following build error:

gfortran -Wall -O2 -fallow-argument-mismatch -c absolute_relative.f gfortran: error: unrecognized command line option ‘-fallow-argument-mismatch’; did you mean ‘-Wno-argument-mismatch’? make: *** [Makefile:11: absolute_relative.o] Error 1 ==> ERROR: A failure occurred in build().

@dkcampbell thank you very much! I'have been quite busy in the last couple of days. I'll merge your patch by the end of tomorrow, thanks again.

I have problem then compiling ccx (MKL)

Im add -fallow-argument-mismatch to Makefile ( )

Hi @mauritiusdadd, the build issues @crataegus and myself are experiencing is caused by changes to the default options used by gcc, and gfortran with the release of gcc 10. For gfortran, a warning, by default is now an error, and for gcc, an ignored warning, became an error. Here's a link to a patch to fix the issue:

I applied it on top of your patch. Feel free to merge this into your existing patch.

Thanks for your work maintaining this package!
