Jeff thanks again for your help I now understand which one is the netcdf library and therefore successfully compile using netcdf. -----Original Message----- From: Jeff Whitaker [mailto:jswhit@xxxxxxxxxxx] Sent: Friday, February 02, 2007 7:39 AM To: Yair suari Cc: netcdfgroup@xxxxxxxxxxxxxxxx Subject: Re: undefined reference using netcdf library Yair suari wrote: > i dont think its finding the library but when i look at the netcdf.a > (using nm command) i can see the functions which could not be found. > during my googling i found two things related to such problems one has > something to do with added underscore to function names during > compilation and the other with the -i switch but i could stil not > solve the problem. > thanks alot for your help > yair > > On 2/2/07, *Jeff Whitaker* <jswhit@xxxxxxxxxxx > <mailto:jswhit@xxxxxxxxxxx>> wrote: > > Yair Suari wrote: > > Jeff thanks for your help > > I tried to link the compiler to the netcdf.mod file but it did > not help > > (before I had a link to that file in the compiling folder) > > The massages I get are not from not seeing netcdf.mod > > I did see people use the -I switch but did not understand where > do they > > point it to. > > Thanks again > > yair > > > > -----Original Message----- > > From: Jeff Whitaker [mailto: jswhit@xxxxxxxxxxx > <mailto:jswhit@xxxxxxxxxxx>] > > Sent: Thursday, February 01, 2007 5:47 AM > > To: Yair suari > > Cc: netcdfgroup@xxxxxxxxxxxxxxxx > <mailto:netcdfgroup@xxxxxxxxxxxxxxxx> > > Subject: Re: undefined reference using netcdf library > > > > Yair suari wrote: > > > >> i an a new user to netcdf,unix,fortran so this will probably be > easy > >> to most of you but i cant get to start using the netcdf interface. > >> when trying to compile i get the following massages: > >> > >> yair@yairsuari:~/fortran/cdfdata$ ifort create.f90 -g -o create.o > >> /tmp/ifortmAdSAz.o: In function > >> `cdfcreate':/home/yair/fortran/cdfdata/create.f90:5: undefined > >> reference to `netcdf_mp_nf90_create_' > >> /tmp/ifortmAdSAz.o: In function > >> `handle_err':/home/yair/fortran/cdfdata/create.f90:12: undefined > >> reference to `netcdf_mp_nf90_strerror_' > >> > >> i am using ubuntu (debian based linux) on x86 machine and intel > >> fortran compiler 9.1 > >> > >> when googling around for this i saw a similar problem created when > >> using a different compiler for your programs and for the netcdf > >> compilation but this is not the case, i have always used intel. > >> > >> please HELP > >> yair > >> > >> -- > >> Yair Suari > >> Hamafteach 23 Michmoret Israel 40297 > >> Phone-0528-524520, 09-8664245 > >> > > > > Yair: You need to use pass ifort (or any fortran compiler) the > location > > of 'netcdf.mod', via '-I/path/to/module' and the library via > > '-L/path/to/netcdf/library -lnetcdf'. > > > > -Jeff > > > > > > Yair: What about the -L flag?
