Overlapping Access to 'N' Error #689

Closed traviskirton closed 7 years ago

traviskirton commented 7 years ago

When compiling C4iOS in Xcode 9, the following code generates an error in `

Transform.swift`:

    // LU factorisation
    dgetrf_(&N, &N, &matrix, &N, &pivot, &error)
    if error != 0 {
        return nil
    }

    // matrix inversion
    var workspace = [__CLPK_doublereal](repeating: 0, count: 4)
    dgetri_(&N, &matrix, &N, &pivot, &workspace, &N, &error)
    if error != 0 {
        return nil
    }

Error Message: Overlapping accesses to 'N', but modification requires exclusive access; consider copying to a local variable
