This has worked for me in the past:
```
# Template file for 'gf2x'
pkgname=gf2x
version=1.3.0
revision=1
build_style="gnu-configure"
short_desc="C/C++ library for fast arithmetic in GF(2)[x]"
maintainer="Gonzalo Tornaría <tornaria@cmat.edu.uy>"
license="GPL-3.0-or-later"
homepage="http://gf2x.gforge.inria.fr/"
distfiles="https://gforge.inria.fr/frs/download.php/file/38243/${pkgname}-${version}.tar.gz"
checksum=9472cd651972a1de38e3c4c47697a86e0ecf19d7d33454d4bc2a62bc85841b59

gf2x-devel_package() {
	depends="gf2x-${version}_${revision}"
	short_desc+=" - development files"
	pkg_install() {
		vmove "usr/include"
		vmove "usr/lib/*.a"
		vmove "usr/lib/*.so"
	}
}
```

Note that the homepage has changed, but the release file is still the same, can be downloaded, e.g. from
`https://gitlab.inria.fr/gf2x/gf2x/uploads/c46b1047ba841c20d1225ae73ad6e4cd/gf2x-1.3.0.tar.gz` and it has the same sha256.
