[PVFS-users] Linking Problem to libpvfs.a under glibc-2.1.2

[Phil Carns]

Hi Jeff,

Since you are using native pvfs calls (pvfs_open rather than open, for
example), you can get around this by linking against libminipvfs.a.  It is
a simpler library that only includes pvfs_XXX calls.  It is located
in the /usr/lib/ directory so the command line would just be:

gcc test.o -o test -lminipvfs -lm 

That being said, it seems like the way that you were previously doing it
with the full pvfs library should have worked, however.  What version of
pvfs are you using?  Did you build it from source, or is it an rpm?

thanks,
-Phil
