[maker-devel] MAKER can't find forks in @INC, but it is there

Fields, Christopher J cjfields at illinois.edu

Just a note: when we install MAKER we generally install a clean version of perl if one isn’t already present, making sure it is on the NFS share for the cluster (which is accessible via all nodes).  This works around most of the issues you describe.

I found my errors.

1) In my machine file; the first entry was not the main node, so locate was looking on a different node than Maker
2) forks (and other modules) were not properly installed on every node in the cluster.  I used CPAN to install them on each cluster and it is now working.

I wasn't sure what modules were separated (figured it was wroth a shot), however, I did the force install of forks and I still get the same error.  I tried uninstalling and reinstalling all the forks installations that showed up and commented out the PERL5LIB export I had in my ~/.bashrc (then reloaded) to make sure I wasn't getting some kind of conflicting libraries/modules. and I'm back to:

Now it's a maker issue, not a forks issue (if I'm reading it correctly), so I reinstalled Maker (made sure to direct to mpicc and mpi.h properly) and got:

$ sudo ./Build install
Installing MAKER...
Configuring MAKER with MPI support
Skip /Data/Apps/maker/src/../perl/config-x86_64-linux-gnu-thread-multi-5.022001 (unchanged)

I don't believe that's an error or even a warning, but I get the same "can't locate forks" error when I try to run it.

forks::signals is part of forks. It’s not a separate package. If it’s missing, there is a problem with the forks installation. So you need to do a force install of forks to force the reinstall.

Example —>         cpan[1]> force install forks

I tried this and still get the same error.  Then I tried forcing a reinstall of forks/signals and got:

cpan[1]> install forks::signals
Warning: Cannot install forks::signals, don't know what it is.
Try the command

    i /forks::signals/

to find objects with matching identifiers.

but scrolling through the install scroll of the forks reinstall I do see it got installed properly.

Hi Everyone,

After sorting my MPICH/OpenMPI issue I have come across another: When I try to run MAKER on the demo data via

Since /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 is in INC I initially thought this was a Perl error.  I hit up perlmonks and found that there is an issue between forks and Storable, where Storable now has a verion number of X.Y_Z but forks is only looking for X.Y (no _Z).  I followed these instructions https://rt.cpan.org/Public/Bug/Display.html?id=102730<https://urldefense.proofpoint.com/v2/url?u=https-3A__rt.cpan.org_Public_Bug_Display.html-3Fid-3D102730&d=DwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=fbHa8Njtvh9VmSnzJxiEUTW9NWDwMMwQAzhgZDO41GQ&m=PL_vqUhNnKqhtQS6zHa9WJqgP5Vr3Qe-GdG8b6vSQ3I&s=yUtqaTYl3_yoaALp6kXKDMLyYyPeO27hCpGA9ZDa2aI&e=> and tried again.
