Bug#947827: Missing symbols in -lblas ?

[Julien Puydt]

Package: libatlas3-base
Version: 3.10.3-9

I tried to work on the scilab package, but couldn't get very far : for
some reason, the configure script was failing to detect the umfpack
library. But looking in config.log, I found out the reason was that the
BLAS used is atlas, and linking to it gives many undefined references :

I tried to make a simpler failing test.c:
  int umfpack_di_solve();

  int main()
  {
    return umfpack_di_solve();
  }

compiles with gcc -o test test.c -lumfpack
doesn't compile with gcc -o test test.c -lumfpack -lblas
compiles with gcc -o test test.c -lumfpack -llapack -lblas

Hope it helps,
