[Pvfs2-users] warning msg when compiling pvfs-2.6.3

[xiangyong ouyang]

I m compiling pvfs-2.6.3 with IB support (ofed-1.2). Below is my config flag:

./configure --prefix=/tmp --with-db=/tmp/BerkeleyDB --with-openib=/usr/local/ofed --with-openib-libs=/usr
/local/ofed/lib64 --with-openib-includes=/usr/local/ofed/include --with-mpi=/home/ouyangx/mpich2-install 
--with-kernel=/usr/src/linux-2.6.20.5

make


During make, I received some warning msg. One bunch of warnings (as follows) reoccurs 3 times:


In file included from src/io/bmi/bmi_ib/openib.c:19:

It seems some local variables mask out global variables. Will this cause problems in my future programming? thanks!
