[petsc-users] Installing Triangle for PETSc by not using --download

[Satish Balay]

Can you try the --with-packages-download-dir option?

It tells you the URL to download - and then PETSc configure does the install.

--------

balay at p1 /home/balay/petsc (release =)
$ ./configure --with-packages-download-dir=$HOME/tmp --download-triangle
Download the following packages to /home/balay/tmp 

triangle ['git://https://bitbucket.org/petsc/pkg-triangle', 'https://bitbucket.org/petsc/pkg-triangle/get/v1.3-p2.tar.gz']

Then run the script again

balay at p1 /home/balay/petsc (release =)
$ pushd $HOME/tmp
~/tmp ~/petsc
balay at p1 /home/balay/tmp
$ git clone -q https://bitbucket.org/petsc/pkg-triangle
balay at p1 /home/balay/tmp
$ popd
~/petsc
balay at p1 /home/balay/petsc (release =)
$ ./configure --with-packages-download-dir=$HOME/tmp --download-triangle
