Hi @gdolle,

Well let's review those dependencies then? When you say 'all opt depend aren't functional' do you mean those specified by the ./configure arguments in the PKGBUILD?

(...)
./configure --prefix=/usr \
            --enable-summary \
            --with-petsc=${PETSC_DIR}/lib/petsc/conf/petscvariables \
            --with-slepc=${SLEPC_DIR}/lib/slepc/conf/slepcvariables \
            --disable-superlu \
            --disable-mumps_seq
            #--with-ipopt-include 
            #--with-superlu-include=/usr/include/superlu \
./reconfigure
(...)

i.e. petsc, slepc, superlu, mumps and coin-and-ipopt? Because since I previously installed numpy, scipy, matplotlib, julia and octave, freefem will always compile with boost, cblas, fftw, lapack and mepis, all stated as 'optional' by this pkgbuild, and those are automatically detected by the configure script, aren't they?

Anyways, from https://doc.freefem.org/introduction/installation.html#compilation-on-arch-linux we got, at least:

1. Install the following dependencies:

pacman -Syu
pacman -S git openmpi gcc-fortran wget python
    freeglut m4 make patch gmm
    blas lapack hdf5 gsl fftw arpack suitesparse
    gnuplot autoconf automake bison flex gdb
    valgrind cmake texlive-most

Just installed valgrind, and I got this ./configure output using your script:

So from those opt deps I've got installed, only boost fails to be included.

Hi @lmello, yes it's not really essential for the current build (no external pkg *), I'll change it next update.

NB: *Be aware this is a minimal dependency ff++ build and several features are missing (all opt depend aren't functional)

Follow-up: I just rebuilt the AUR package with pamac, editing the PKGBUILD accordingly. Opened a new terminal after installation and it worked just fine. So that the extra 'freefem.csh' and 'freefem.sh' source files (profile path/env scripts) are not necessary anymore with '--prefix=/usr'.

I suggest that you update the PKGBUILD with those minor edits, if only for system coherence.

@Sosthene

As of 2021-02-07, this build works flawlessly on a Manjaro box.

I was just wondering if the '--prefix=/opt/freefem' is essential for it in any way; from the looks of it, I don't see why the standard '--prefix=/usr' packaging shouldn't work.

@gdolle I became the maintainer of this package because it was orphaned an I needed it for a course I was taking. I don't really use it anymore so I have no idea whether the package works properly.

If you use It and know the build system I'd be grateful if you maintained it, and you'd probably do a better job than I.

petsc should be a strong dependency (mumps and hpddm will be provided via petsc). Otherwise a lot of solvers won't be available

It seems that unzip, m4, flex and bison are missing as dependencies.

configure: to install missing package under debian or ubuntu, try configure: sudo apt-get install unzip configure: error: Sorry missing unzip,m4,bison,flex,patch command ! ==> ERROR: A failure occurred in prepare(). Aborting... Error making: freefem

Patches are welcome.

@greyltc yes, the build process download dependencies (like mumps, etc). Not sure it's a good idea to do it appart

Am I right in that the build process downloads something besides the URLs in the source array? Can we avoid that somehow?
