rpm information generic source?

English Applications
#1

I’m not sure this question belongs in the Apps forum… I’ve been looking for a source of pertinent information on rpm’s in general. Right now, I need to know if the stock OpenSuSE12.1x64 NetCDF was compiled with both gFortran and OpenMPI support. Is there a generic online source of such information? This sort of thing usually is not carried in the YaST database and I haven’t found it anywhere else (like pbone).

THANK YOU!!!

Hi
All on the Open Build Service, if you go to software search;
http://software.opensuse.org/search?
Enter netcdf then clicking on the name and release will take you to the
Open Build Service package and you can inspect the spec file and other
details as well as the build log…
https://build.opensuse.org/package/view_file?file=netcdf.spec&package=netcdf&project=openSUSE%3A12.1&rev=f4986b5839d4de07b53fd17c631eec6e

I’ve seen some applications that let you find out at runtime what
compile options were there from the start, but I think that’s
application-specific. I would start, since this is RPM-based, by
checking the Source RPM file and viewing the SPEC file contained within.
For example, I pulled netcdf from the OpenSUSE Build Service and found
this line in the SPEC file:

export CC=gcc CXX=g++ FC=gfortran
CFLAGS="%{optflags}" CXXFLAGS="%{optflags}" FCFLAGS="%{optflags}"

That makes me think it is compiled with gfortran support, and I see
references to MPI in the file in the changelog (query from an installed
package with rpm -q --changelog packageNameHere) so I assume that’s
just there.

Good luck.

WOW!!! Thanks everyone!!!

Hi Malcom - I tried doing this with HDF5 (I need it to be built to support MPI/parallel) - but couldn’t find a link to take me to the spec file:
software.opensuse.org:
…there must be some place to click I’m forgetting because I remember figuring it out before. These “slick” interfaces tend to be nonintuitive unless you work with them all the time… How do I view a spec file again?

#6

Hi
Click the ‘unstable link’ your best to pick the devel project for the
package (which I happen to know is the devel libraries…)
https://build.opensuse.org/package/view_file?file=hdf5.spec&package=hdf5&project=devel%3Alibraries%3Ac_c%2B%2B&rev=f995c7e42cde733baca843157d33d06b

Or you can just go direct to https://build.opensuse.org/project/show?project=openSUSE%3AFactory find
the package an work back.

Well, I get as far as: openSUSE Build Service > Projects > devel:libraries:c_c++ > Packages > hdf5

but can’t find the link to the next step: openSUSE Build Service > Projects > devel:libraries:c_c++ > Packages > hdf5 > files

or to: openSUSE Build Service > Projects > devel:libraries:c_c++ > Packages > hdf5 > files > hdf5.spec

I guess being color-blind, I can’t see the links?

Oh, wait a second - I can get to openSUSE Build Service > Projects > devel:libraries:c_c++ > Packages > hdf5 > Sources
…and that seems to have the spec file in it. I would have never thought to look in “unstable” for a stock 12.1 package.

So - I do see mention of “parallel” in the spec file in a couple of places in the .spec file - does that mean it’s compiled with parallel support? (so I can use parallel-NetCDF)

Could it be? The netCDF.spec file says “parallel” - could it be the default OpenSuSE NetCFD is, in fact, a version of parallel-netcdf? If so, where is the pnetcdf.h file?

Hi
I would assume so, you would need to look at the source tarball readme
or other documentation to see the compile time options. Or else on the
OBS page fire an email off to the package maintainer to ask…
