{you can safely skip this paragraph, it’s an apology}
I know that it says on the community page to ask questions about installation on the mailing list, but I have the suspicion that the “love” that I have for Google is reciprocal (I never got an e-mail to join the list).
I am trying to install Dolfin (my end goal is Dolfin_Warp). I created an AUR package for basix which I could install. It does not work.
This leads to an error when compiling dolfin-git (see below). How do I compile basix from source as a package for AUR? (I use an Arch-derivative). Thanks.
==== Edit 1 (30/08/2021) ====
May be I should be more specific: to install with a PKGBUILD,
- one needs to specify a temporary installation path
- which is later compressed into an actual package.
This path is independent of the building path and - part of it is stripped from file names during compression (e.g. /my/pkg/usr/ becomes /usr).
If you look at the link which I provide above, you will find that I do:
_realname=basix
cmake -DCMAKE_BUILD_TYPE="Release" \
-B "${srcdir}"/build \
-S "${srcdir}"/"${_realname}" \
-DCMAKE_INSTALL_PREFIX=/usr \
-DCMAKE_PREFIX_PATH="${srcdir}"/build \
-DXTENSOR_OPTIMIZE=TRUE \
-Dxtensor_DIR=\
"$(pacman -Ql xtensor |
awk '/xtensorConfig\.cmake/{print $NF}')"
cmake --build "${srcdir}"/build
# --- skipped lines ---
cd "${pkgdir}"
make -C "${srcdir}"/build DESTDIR="${pkgdir}" install
(${srcdir}
is the folder where the git repository of basix lives)
The following error happens with the installation of dolfin-git (from AUR). I suspect that my basix installation is wrong.
