Hello, developers of Aspect: I’m currently installing Aspect using candi, and I’ve encountered the following issues. There is an issue during the installation of Trilinos 14 - 4 - 0. It requires BLAS to support floating - point operations. However, I’ve already installed BLAS, LAPACK, and OpenBLAS, but I still get the following error. – Creating ETI files for Blas1\_axpby\_mv – Creating ETI files for Blas1\_update – Creating ETI files for Blas1\_update\_mv – Creating ETI files for Blas1\_sum – Creating ETI files for Blas1\_sum\_mv – Creating ETI files for Blas1\_nrm1 – Creating ETI files for Blas1\_nrm1\_mv – Creating ETI files for Blas1\_nrm2w – Creating ETI files for Blas1\_nrm2w\_mv – Creating ETI files for Blas1\_nrminf – Creating ETI files for Blas1\_nrminf\_mv – Creating ETI files for Blas1\_iamax – Creating ETI files for Blas1\_iamax\_mv – Creating ETI files for Blas1\_nrm2 – Creating ETI files for Blas1\_nrm2\_mv – Creating ETI files for Blas1\_mult – Creating ETI files for Blas1\_mult\_mv – Creating ETI files for Blas1\_reciprocal – Creating ETI files for Blas1\_reciprocal\_mv – Creating ETI files for Blas1\_rot – Creating ETI files for Blas1\_rotg – Creating ETI files for Blas1\_rotm – Creating ETI files for Blas1\_rotmg – Creating ETI files for Blas1\_swap – Creating ETI files for Blas2\_gemv – Creating ETI files for Blas2\_ger – Creating ETI files for Blas3\_gemm – Creating ETI files for Blas3\_trsm – Creating ETI files for Blas3\_trmm – Creating ETI files for Blas\_trtri – Creating ETI files for Graph\_color\_d1 – Creating ETI files for Sparse\_sptrsv\_solve – Creating ETI files for Sparse\_spmv\_struct – Creating ETI files for Sparse\_spmv\_mv\_struct – Creating ETI files for Sparse\_spmv\_bsrmatrix – Creating ETI files for Sparse\_spmv\_mv\_bsrmatrix – Creating ETI files for Sparse\_spmv – Creating ETI files for Sparse\_spmv\_mv – Creating ETI files for Sparse\_spgemm\_symbolic – Creating ETI files for Sparse\_spgemm\_numeric – Creating ETI files for Sparse\_spgemm\_noreuse – Creating ETI files for Sparse\_bspgemm\_numeric – Creating ETI files for Sparse\_spgemm\_jacobi – Creating ETI files for Sparse\_spadd\_symbolic – Creating ETI files for Sparse\_spadd\_numeric – Creating ETI files for Sparse\_spiluk\_symbolic – Creating ETI files for Sparse\_spiluk\_numeric – Creating ETI files for Sparse\_par\_ilut\_symbolic – Creating ETI files for Sparse\_par\_ilut\_numeric – Creating ETI files for Sparse\_gmres – Creating ETI files for Sparse\_sptrsv\_symbolic – Creating ETI files for Sparse\_trsv – Creating ETI files for Sparse\_gauss\_seidel\_symbolic – Creating ETI files for Sparse\_gauss\_seidel\_numeric – Creating ETI files for Sparse\_gauss\_seidel\_apply Processing enabled top-level package: RTOp (Libs) Processing enabled top-level package: Sacado (Libs) – Performing Test HAS\_C99\_TR1\_CMATH – Performing Test HAS\_C99\_TR1\_CMATH - Success Processing enabled top-level package: Epetra (Libs) – Looking for dggsvd3 – Looking for dggsvd3 - not found – Looking for dggsvd3\_ – Looking for dggsvd3\_ - found – Looking for DGGSVD3 – Looking for DGGSVD3 - not found – Looking for DGGSVD3\_ – Looking for DGGSVD3\_ - not found Found new version of lapack. dggsvd3 is available.

@YUAN The error message describes what is going wrong: ```auto This means that you are linking with a BLAS library that lacks float (S) support. Tpetra needs a BLAS implementation that supports float. ``` BLAS defines functions for single precision (`float`, “S”) and double precision (`double`, “D”) data types. Apparently your BLAS only has the latter but not the former. The question for you to answer then is why that is so – in particular, where does the BLAS installation on your system come from, and why is it missing the `float` functions? Best W. ---
