[Debichem-devel] disabling PeIGS in libglobalarrays-dev

[Drew Parsons]

Hi Michael, the ga build has been missing symbols:

    ./.libs/libga.a(ga_diag.o): In function `gai_diag_std_':
    ga_diag.F:(.text+0xc65): undefined reference to `fmemreq_'
    ga_diag.F:(.text+0xecd): undefined reference to `pdspev_'

I raised the issue upstream at 
https://github.com/GlobalArrays/ga/issues/154

Jeff explained that these are PeIGS symbols, provided by nwchem.  It 
hasn't been causing problems in practice since nwchem is the only 
program currently using GA.

Nevertheless Jeff and his upstream coauthors recommend disabling PeIGS 
in GA to avoid the problem, especially since scalapack is available for 
GA anyway.

You enabled PeIGS just in the previous Debian release, so I wanted to 
let you comment. Should we go ahead and disable peigs, or keep it 
enabled all the same?
