I want to re-emerge lam-mpi but have it be built so that if I was compiling from source I could set the ./configure --without-fc option?

I don't know if I should edit the ebuild or set some kind of pre-emerge variable or edit the make.conf file.

Thanks,
Sky

The quick fix is to edit the ebuild and add the without-fc option like this..

Code: Select all

src_compile() {

    local myconf

    if use crypt; then
        myconf="--with-rsh=ssh --without-fc"
    else
        myconf="--with-rsh=rsh --without-fc"
    fi

    econf \
        --sysconfdir=/etc/lam-mpi \
        ${myconf} || die

    # sometimes emake doesn't finish since it gets ahead of itself :)

    make || die
}

but from what I read, the better fix is to add f77 to you use flags and re-compile gcc. I don't use lam-mpi so I took the quick route.

HTH.

Thanks for investigating. I did add the f77 to my USE flags and recompile gcc. This allows lam-mpi to install. I can lamboot a cluster of 2 pc's(haven't rolled the rest out yet) and but I can't install the lam-mpi test suite. A fix on another forum (non Gentoo) suggested recompiling lam-mpi --without-fc.

I'll be working with a programmer soon to make sure his mpi code works. If it does I'll just forget about getting the testing software to work.
