New package: CalculiX-2.20

[Phicem]

NEW PACKAGE - CalculiX

This new package conforms to the package requirements: YES

CalculiX is a 3D finite element program. It is an optional but important dependency of FreeCAD (for mechanical and thermal calculations). This PR is related to issue #5603.

CalculiX is split in two parts: the solver (CalculiX-ccx) and the graphical interface and pre/post-processing (CalculiX-cgx).

This PR includes 4 packages, each in a separate commit:

• spooles (build dependency for CalculiX-ccx)
• CalculiX-ccx
• CalculiX-cgx (including tetgen binary)
• CalculiX meta-package (which brings CalculiX-ccx and CalculiX-cgx)

Tests

Local build testing

• Native x86_64 (glibc and musl): OK
• Native i686 (glibc) (from an x86_64 machine) : OK
• Native armv7l (glibc): OK

Cross build testing (from x86_64 machine)

• Cross-compiling to armv7l: OK (requires using ./xbps-src binary-boostrap i686 on an x86_64 system, otherwise it fails)
• Cross-compiling to aarch64: OK

Runtime testing

• On x86_64 (glibc): OK (for CalculiX-ccx: some calculation tests differ from the official reference results files)
• On armv7l: OK (for CalculiX-ccx: some calculation differences too)
• On i686: NOT TESTED

just a couple of things i noticed. there's a lot of work to be done here, I think, but I need to look into this more

[classabbyamp]

ok I think that's everything that I can see

Suggested change

	build_style="gnu-makefile"
	make_cmd="make -C ${pkgname}${version} -f makefile"
	build_style=cmake

the cmake files provided are a bit better than the makefile

[classabbyamp]

Suggested change

	do_build() {
	make CC=$CC CXX=$CXX CFLAGS="$CFLAGS"
	}

Thank you for all your comments! I marked the PR as draft until I test all these modifications.

I think the packages are ready for review!

tetgen binary is now built directly in CalculiX-cgx package.

I took all your comments into account (with one exception: I still use make instead of cmake for tetgen binary, because it's more practical since I can't use the cmake build method of xbps-src).

I also added a -O2 flag in FFLAGS of CalculiX-ccx.

I also added a -O2 flag in FFLAGS of CalculiX-ccx.

it's already in there:

void-packages/etc/defaults.conf

Lines 36 to 38 in fedd110

	XBPS_CFLAGS="-O2 -pipe"
	XBPS_CXXFLAGS="${XBPS_CFLAGS}"
	XBPS_FFLAGS="${XBPS_CFLAGS}"

Actually I used a variable named _FFLAGS instead of FFLAGS, because an xlint warning told me to prefix custom variables with_. I did not realize that this change of name would make me lose the benefit of getting default FFLAGS.

I will fix this and use FFLAGS directly, but I'm expecting that xlint test will fail. By the way, shouln't we add FFLAGS to the list of official variables recognized by xlint?

(I keep this last change as a separate commit, I'll rebase if the change is okay.)
