Some WSL install questions

[walt.brainerd]

I do have CAF working using WSL, but I still have some questions.

The first is more a Ubuntu question, but I suspect somebody here can answer it:

What is the difference between apt and apt-get? Does it matter?

Here are the main steps of what I have done so far after installing Ubuntu:

sudo apt-get update

sudo apt-get install mpich

git clone https://github.com/sourceryinstitute/opencoarrays.git

cd opencoarrays

./install.sh

install.sh seems to find version 3.1 of mpich even though 3.2 was installed (above).

How do I tell it to find 3.2? The -M option looks like it, but I don't know what to give

as the argument to the option. (The ones in the example in install.sh-usage didn't

seem to work--there are no mpich files in either place.)

[BTW, there is a small typo in install.sh-usage: One of the examples under the -M

option uses -m (lower case).]

The -i (--install-prefix) seems to have no effect. I tried -i ${PWD} in the high-level

directory "opencoarrays" and it still installs in prerequisites/ .... /2.1.0

This works anyway, but I would like to have a little cleaner way of doing all this,

for example, so I didn't have to add that long directory name to my PATH.

I can't get "make uninstall" to do anything, but I guess that is not terribly important.

I can just remove the entire opencoarrays directory.

My understanding is that apt replaces apt-get for most users for most purposes. I have 

yet to find any differences between the two, but I've read that apt is now the recommended 

default.

Here are the main steps of what I have done so far after installing Ubuntu:

sudo apt-get update

sudo apt-get install mpich

git clone https://github.com/sourceryinstitute/opencoarrays.git

cd opencoarrays

Apologies.  The -M argument assumes that all MPI installation files are under a common

root directory.  If mpifort and mpirun are in /usr/bin and /usr/lib, respectively, then the

common root directory would be /usr.

[BTW, there is a small typo in install.sh-usage: One of the examples under the -M

option uses -m (lower case).]

Thanks!   If it's easy for you to submit a pull request with a correction, please do. 

The -i (--install-prefix) seems to have no effect. I tried -i ${PWD} in the high-level

directory "opencoarrays" and it still installs in prerequisites/ .... /2.1.0

-i only controls the location of the final package installed.  If that package is OpenCoarrays,

then all missing prerequisites will be installed in prerequisites/installations.  To ensure that

each prerequisite goes to a different location, the installer must be run separately for just

that prerequisite package installation (e.g., ./install.sh -p mpich -i /opt/mpich). I'm going to 

add a new --install-root option that will facilitate installing all prerequisites and the final

package in a common root path. 

This works anyway, but I would like to have a little cleaner way of doing all this,

for example, so I didn't have to add that long directory name to my PATH.

There should be a setup.sh (and setup.csh) file that can be sourced to set up the 

PATH. 

 

I can't get "make uninstall" to do anything, but I guess that is not terribly important.

I can just remove the entire opencoarrays directory.

We haven't implemented the uninstall option.  Thanks for expressing interest in it,

Damian
