SUMMARY

The installation of the ARPACK library on Windows is encountering a critical error: "make (e=2): The system cannot find the file specified." This error typically arises when essential tools or files are not included in the system's PATH or are missing altogether. The user has modified the ARmake and Makefile but still faces issues, indicating potential misconfigurations. Additionally, the presence of LAPACK and BLAS files in the ARPACK directory raises questions about their necessity for successful installation.

PREREQUISITES
  • Familiarity with Windows command line operations
  • Basic understanding of Makefile syntax and structure
  • Knowledge of ARPACK library dependencies, specifically LAPACK and BLAS
  • Experience with MinGW and gfortran installation and configuration
NEXT STEPS
  • Verify and update the system's PATH variable to include MinGW and gfortran
  • Research the correct configuration of ARmake and Makefile for ARPACK installation
  • Explore precompiled ARPACK binaries for Windows to avoid manual compilation
  • Investigate the role of LAPACK and BLAS in ARPACK to determine if they are necessary
USEFUL FOR

Developers and researchers needing to install the ARPACK library on Windows, particularly those working with numerical computations that require this library for calculations.

TL;DR
I need to install the ARPACK library for windows
hi all
I am trying to install the ARPACK library for windows (another program needs the library for calculations) , I download a arpack96.tar.gz file that i found online , downloaded "make" and the mingw-gfortran and all that, modified the ARmake and the Makefile, but when i try the command "make lib" it shows the following error :
make (e=2): The system cannot find the file specified.
Makefile:57: recipe for target 'arpacklib' failed
make: *** [arpacklib] Error 2
has any one encountered the same error when trying to install ARPACK on windows, also do I need LAPACK and BLAS, because in the ARPACK folder it already has both files in its directory.
I will appreciate any help, thanks in advance.

also cant i just download an already "maked lib" library instead of going through all that hassle!

If you encounter the error message "make (e=2): The system cannot find the file specified," it usually indicates that one of the required tools or files is not in your system's PATH or is missing

the folder of the ARPACK does not contain any folder named "arpacklib" is that the missing folder?where do i get it
