I'm trying to use the library ARPACK in the intel visual fortran complier(VS2008). At first, compling of ARPACK using MinGW was successful and I got arpack_x64.dll and arpack_x64.lib (object file library) files. However, now I'm stuck in liking those files to my fortran project.
My ARPACK directory is 'D:\1_STUDY\ARPACK', and following is the procedure that I have made to link the library (actually I'm not sure this is correct).
(1) Linker>Input>Additional Dependencies : D:\1_STUDY\ARPACK\arpack_x64.lib
(2) Tools>Option>Intel(R) Visual Fortran>Compilers:
- Add to Libraries: D:\1_STUDY\ARPACK\arpack_x64.lib
- Add to Includes: D:\1_STUDY\ARPACK\arpack_x64.dll
<Main.f source code>
DOUBLE PRECISION A(2,2)
CHARACTER*2 which ! Hermitian or non-Hermitian
INTEGER nev ! # of eigvalues to be computed
DOUBLE PRECISION tol ! tolerances
INTEGER ido ! reverse communication flag
INTEGER ncv ! # of Lanczos basis vectors to use
double precision, allocatable :: resid(:)
integer, allocatable :: workl(:),workd(:),v(:,:)
maxn = 256
maxnev = 10
maxncv = 25
ldv = maxn
A = 0.D0
A(1,1) = 10.D0
A(1,2) = 11.D0
A(2,1) = 11.D0
A(2,2) = 20.D0
PRINT *, A
which = 'LM' ! eigvalues largest in magnitude
bmat = 'I' ! standard eigvalue problem
n=2 ! dimension of the problem
nev = 2 ! # of eigvalues to be computed
tol = 1.d-10
IPARAM(1) = 1 ! default exact-shift strategy
IPARAM(3) = 100 ! max. # of implicit restarts allowed
IPARAM(7) = 1 ! regular mode
ido = 0
ncv = 5 ! at least nev+1 (setting ncv>2*nev is recommended)
LINK : fatal error LNK1181: 'D:\1_STUDY\1_MATERIALS\00_ARPACK\test\test\arpack_x64.lib' (cannot be opened).
So, I added the arpack_x64.lib and arpack_x64.dll files to the same directory with the main.f file. Then, the above error disappeared, but the following error occurred.
1>MAIN.obj : error LNK2019: DSAUPD (unresolved external symbol)
Then, to curcumvent this trouble, I added include 'arpack_x64.lib' just before the executable section. However, the following error occurred.
1>D:\1_STUDY\1_MATERIALS\00_ARPACK\test\test\arpack_x64.lib(2): error #5149: Illegal character in statement label field [/]

I want to save the .dll and .lib files to a canonical place and use them instead of copying the files into the local directory every time.
I'm really not sure that the procedure I followed was in right direction since I'm a novice on this library installation.
So any helps or comments are welcome.
The Tools > Options page you're using isn't for adding specific files to a build, it is where you specify the list of directories the compiler and linker will search. What you want to do instead is add the .lib to the project property Linker > Input > Additional Dependencies. You don't do anything with the DLL when building the application - that is found by Windows when you run the program using its normal rules. (Hint - one usually places the DLL in the same folder as the EXE, or add the directory with the DLL to PATH.)
You certainly should not use an INCLUDE statement to bring in a library!
The default name mangling of MinGW/GFortran differs from that of IFort. If you use the GFortran defaults, the Arpack DLL (and import library) will have lowercase names for the exported symbols (e.g., dsaupd_ rather than DSAUPD). The convention for adding underscores may also differ. You can fix things up using compiler options or by inserting directives in the source code, either with the GNU tools or with the Intel compiler, but take care to coordinate the two toolchains and make the symbol decorations compatible.
A simpler alternative is to use IFort to compile all the source files in the SRC and UTILS subdirectories of the Arpack distribution (after extracting the main tar file from the Rice University site and then the patch tar file), and combine all the resulting object files into a static library or a DLL.
There is more than one distribution of Arpack. For details and a discussion of some of the issues related to building and using Arpack, see https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/685394 .
i am beginner of Fortran90 user.
i am trying to link ARPACK to Visual studio 2010.
But i can't find any hint to making ARPACK. lib and .dll flies.
I spent whole a week. T-T
Could you please share the .lib and .dll files?
thanks you, from Lee
