Hi Laurent

Very funny. PS: I am rather new to gcc and make:

#info arm-elf-gcc
(a lot of non-informative information)
# man arm-elf-gcc
No manual entry for arm-elf-gcc
#


The do***entatation is bloated with options:
http://gcc.gnu.org/onlinedocs/gcc-4.2.3/gcc/
- and this just for gcc - what then about arm-elf-gcc?

That was why I thought it was better to ask here.

Where is the best place for option "-S" in the makefile?:
"...

# ELF-file contains debug information, or not
# (possible values for DEBUG are 0 or 1)
# Extra debug flags can be specified in DBFLAGS
DEBUG   = 1
#DBFLAGS =

# Optimization setting
# (-Os for small code size, -O2 for speed)
OFLAGS  = -Os

# Extra general flags
# For example, compile for ARM / THUMB interworking (EFLAGS = 
-mthumb-interwork)
EFLAGS  =

# Program code run in ARM or THUMB mode
# Can be [ARM | THUMB]
CODE    = ARM

# List C source files here.
CSRCS   = main.cpp

# List assembler source files here
ASRCS   =
...."

kind regards,
