Thank you Susan

My problem for LAPACK using blas.a (not atlas) was two reason.

1. as Craig Tierney points out, ./ is needed in front of each executables.

yup. i just edited the makefile and added the ./'s and it worked. thanks. 
but, there is no output in my ./xdlutime programmer. the headers come out
but there is no values???
 
2. I use 150Mhz PC with 16M Ram .. too much small memory ..

I change the the size of NMAX which is set on line 122 of stimaa.f (512) to very small number.

but I got "Segmentation Error"

but I think that's from too much small memory which you said

because I got the same "Segmentation" problems while I compile SCALAPACK because I have very small memory.
 
Thank you. Susan

Have a Nice Day

I suppose to need a little bit much faster & good memory PC.
