Re: On entry to DGEMV parameter number 6 had an illegal value

  KSPSolve_BCGSL() in src/ksp/ksp/impls/bcgsl/bcgsl.c uses calls to gemv() 
directly.

  Could you please try the following. Edit the file and for alll calls to 
BLAS... and LAPACK... replace the character string by its first character.
For example replace "noTr" with "N". Next before each BLASgemv() put in
a printf("ldMZ %d\n",ldMZ); run make lib shared in that directory
then relink you code and run it. Let us know what happens.
