[Mne_analysis] static executables?

Tue Oct 7 15:02:52 EDT 2014

Hi Eric,

It doesn’t work but I think I know why.
I am using a csh wrapper which executes a python script.
And within the python script I run the mne_ executables with  os.system(cmd)
I think that the python script doesn’t pass the value I’ve set for LD_LIBRARY_PATH to mne_forward_solution unless I explicitly tell it to do so.
I’ll see about getting that to  work.

But is there any way that you  could produce static executables?

Thanks.

Regards,

Don

FYI I originally got the libs from the Ubuntu repos, in case you're curious (or in case I eventually delete the libs from my site):

https://launchpad.net/ubuntu/hardy/i386/libgfortran1
https://launchpad.net/ubuntu/hardy/amd64/libgfortran1

Yes, you should be able to set the LD_LIBRARY_PATH environment variable. In fact this is one of the things that the mne_setup_sh script does to ensure that things like "libquicktime.so" can be found in the mne/lib directory, which is why I typically just put libgfortran.so.1 in there. I don't think you'll need to do anything else, but if it doesn't work you should be able to work out from the mne_setup_sh script if anything else is necessary.

Hi Eric,

Thanks for posting back so quickly.

I would be happy to upload the library with each copy of the job and I do have it.
How do I get the executables to find it in a local directory I create?
Is there an environmental variable, something like LD_LIBRARY_PATH that I can set.

Regards,

Don

Actually, I forgot I uploaded them to my website for convenience at one point:

http://faculty.washington.edu/larsoner/libgfortran.so.1s.zip

Just rename the appropriate libgfortran.so.1.i686 or libgfortran.so.1.x86_64 to libgfortran.so.1, put it in e.g. mne/lib (same place that libquicktime.so lives) and you should be good to go.

If it's easy for you to use Python, equivalent (and in some cases faster or more capable) functionality for setting up volume source spaces and computing forward solutions exists in mne-python.

If it's only the Fortran libraries (specifically libgfortran.so.1) that you need, shoot me an email and I can give you a copy of the x86_64 and i686 versions that other people have used with success (and I have used over many versions of Ubuntu). I recently set up an Ubuntu 12.04 server VM for testing recently, and all I needed to run the MNE command-line tools was a copy of libgfortran.so.1 (which I put in the mne/libs dir), and some of the X libraries which were accessible via apt-get -- I imagine a similar solution would work for you.

Dear MNE team:

I need static executables for mne_volume_source_space and mne_forward_solution .
I am using these in a processing stream which is deployed to the open science grid and am encountering many machines which lack the shared fortran libraries on which the executables in your standard distribution rely.

Is it easy to create relink them to create static versions?
Are there some out there to which you could point me?

I am using version 2.9 of mne_forward_solution (compiled 1Feb2013)
and version 1.11 of mne_volume_source_space (also compiled 1Feb2013).

Thanks for any help you can provide.
