Thanks, Mat. I'll give this a try.

I've also posted the question on the ATLAS support page. If they provide a solution, I'll let you know.

Atlas compiled with pgf77. During the "make check" step, I now get these errors, though.

Is it not able to find these routines because of a naming issue between pgf77 and gcc?

Hi Jim,

It looks like you need to add "-llapack -lblas" to the "LIBS" variable in Make.inc. I'm not sure why these symbols aren't in the versions found in the "lib" directory, but they aren't.

Mat,

I am now getting:

/opt/pgi/linux86-64/13.2/bin/pgf77 -O2 -o xscblat2 c_sblat2.o c_sblas2.o \
c_s2chke.o c_xerbla.o auxiliary.o /home/jn_petersen/numerics/ATLAS3.10.1/my_build_dir/lib/liblapack.a \

I did make the change so it will search the libraries
jn_petersen@chebe-gpu:~/numerics/ATLAS3.10.1/my_build_dir$ grep LIBS Make.inc
LIBS = -lpthread -lm -llapack -lblas

It seems that it should find slmch as a part of the lapack library. Any suggestions now?

I'm not sure why it's not in you Lapack lib. Does "nm" show it in the lib? Is the symbol decorated correctly?
