gcc 3.0.4 problem

gcc 3.0.4 problem

[Professor Gustavo Carri]

	Hello, I am trying to install the High Performance Linpack Benchmark on a 
Beuwolf Cluster. Now, the compiler I use is gcc 3.0.4 on an alpha ev67. But, 
when I am installing 

/usr/local/bin/gcc -o HPL_dlacpy.o -c -fomit-frame-pointer -O3 -funroll-loops 
-Dadd_ -DF77_INTEGER=int - DStringSunStyle -DHPL_CALL_CBLAS  
-I/home/gus/hpl/include -I/home/gus/hpl/include/Linux_21264_CBLAS_gm 
/home/gus/ATLAS/include -I/home/mpich/include ../HPL_dlacpy.c

I get the error

gcc: cannot specify -o with -c or -S and multiple compilations

This is the first time I see this. Where did I make a mistake in the 
installation ?. This is what I get when I run gcc -v

Reading specs from 
/usr/local/lib/gcc-lib/alphaev67-unknown-linux-gnu/3.0.4/specs
Configured with: /home/gus/gcc-3.0.4/configure --with-gnu-as --with-gnu-ld
Thread model: single
gcc version 3.0.4

	I really need help to solve this fast. Thank you.

			Gus

Two mistakes here:

  1. there shouldn't be a space between '-' and 'DStringSunStyle'
  2. you need an '-I' before '/home/gus/ATLAS/include'

although I appreciate that these may have been introduced copying the
error into your e-mail.

You may have to correct CFLAGS or similar in your makefile.
