The instructions tell you to start out by generating make.inc.  How would anyone guess what you have done there?

There seems little point in using icc in place of gcc, particularly if you don't use ifort.

Thanks Tim.. Here are my settings: $CC environment variable is: /apps/ic/ic-2015.3.187/composerxe/bin/icc Make.inc : # # Basic include options. # CC is the C compiler, normally invoked with options CFLAGS. # LINKER and LDFLAGS function as CC and CFLAGS, but for linking stages. # LINKER = $(CC) LDFLAGS = EXTRA_LIBS = -lm # M4 macro preprocessor M4 = m4 M4_OPTS = -B65536 INDENT = indent INDENT_OPTS = -ce -i2 -nfc1 -br -brs -cs -npcs -nprs -npsl # # The name of the libraries to be created/linked to # XBLASLIB = libxblas.a # # The archiver and the flag(s) to use when building archive (library) # If your system has no ranlib, set RANLIB = echo. # ARCH = ar ARCHFLAGS = cr RANLIB = ranlib Where do I specify ifort in make.inc ? What else I should be customizing in make.inc ? Regards Armando

ICC build with -O2 will enable -fp-model:fast while the GCC's -O2 build doesn't. The sanity test for xblas goes fine with ICC when you include CFLAGS = -O2 -fp-model:precise in the make.inc file. When I build xblas with GCC and -ffast-math, the sanity test fails in a similar fashion.

Thanks and Regards
