Q: When compiling Toast++, I get an error message like "undefined symbol: toast_ctrsv__" (or some similar undefined toast_xxx symbol).

A: You probably used an incompatible Fortran compiler to generate the BLAS and LAPACK libraries. If you are compiling these libararies yourself as part of the Toast++ package, make sure that you are using gfortran, and not the old g77 compiler (check the "F77" entry in Makefile.incl). To enforce the use of gfortran, type

setenv F77 gfortran

for csh, or

export F77=gfortran

for bash, before running configure.
