#866: Problem linking to dll's ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- I recently installed the hmatrix package on a Windows 7 system via using the Haskell Platform (installed only a few months ago). The hmatrix installation appeared to be successful (with an OK on foreign functions), and I can successfully compile Haskell programs that use hmatrix functions. However, when I attempt to run these programs I get the follow system error: "The program can't start because lapack.dll is missing from your computer. Try reinstalling the program to fix this problem." I get similar error messages if I attempt to use hmatrix functions in ghci (after importing Numeric.LinearAlgebra). The file lapack.dll is clearly visible in my folder C:\Haskell\gsl, which also includes a gsl subfolder, blas.dll, libgsl-0.dll, and libgslcblas-0.dll. I installed hmatrix with the following parameters cabal install hmatrix --extra-lib-dir=C:\Haskell\gsl --extra-include- dir=C:\Haskell\gsl Why is lapack.dll inaccessible at runtime despite successful installation of the package? -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/866 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
