Description Orion Poplawski 2005-09-29 17:44:23 UTC

Description of problem:
When trying to link to the netcdf library on x86_64, I get:

/usr/bin/ld: ncmex.o: relocation R_X86_64_32 against `a local symbol' can not be
used when making a shared object; recompile with -fPIC

Please recompile with -fPIC.  I already had to do this with my hdf package.

Version-Release number of selected component (if applicable):
netcdf-devel-3.6.0-6.p1.fc4

How reproducible:
everytime

Hi Orion, are you certain that you've encountered a bug in netCDF?  The
"ncmex.o" file that you list is not included in netCDF -- its usually part of an
add-on netCDF-for-MatLAB toolbox.  And if you look in the netcdf.spec file
you'll see that I am indeed using CPPFLAGS="-fPIC" so the vast majority of the
library  (which is in C) does get compiled with that flag.

Or, do I also need to pass "-fPIC" for the bits compiled with gfortran (or g77)
as well?  If so, I'll try to see how to do that...

Gah, so sorry.  I needed to compile my object -fPIC.  Sorry!

Comment 3 Ed Hill 2005-09-29 18:21:07 UTC

No worries!

And I don't think anyone is using the F90 parts of the netCDF static 
library to build any shared libs but, just to be safe, I've added "-fPIC" 
for them as well and checked that into CVS.  They're building right now 
so a new version for FC4+ will be out soon-ish.
