[En-Nut-Discussion] Nut/OS ARM eCross-EABI toolchain

Ok, it seems that the compiler is not found in the search path.

In general this looks ok to me, but I suppose that the .basrc is not
evaluated when calling the compiler from within the qnutconf.

You could try to open qnutconf from within a terminal window.
Anyway you have to logout and re-login first after the changes
of .bashrc take effekt.

If you want to be sure:

Just add the same line at the end of 

/etc/profile

(writable by root only, so edit it with root privileges)

Have you tried to call the compiler by hand from within a terminal
window? 

e.g.:

~/arm-eCross-eabi/bin/arm-eCross-eabi-gcc --version

If it does not start:

Are the attributes set correctly (the x-bit set for the user / group?)?
This should be ok, when just extracting the archive with tar.

Later down I see that you are using a 64bit system. The toolchain is
compiled for 32bit systems. Have you installed the 32bit compatibility
layer / libraries? Perhaps there is any library missing?

Have you just look into the config.log file? (which should be placed
anywhere in the build tree?)

If you can't find it try a 

find . -name config.log

Please let me know if any of the above hints could help you.

I did not yet tried to compile the toolchain on a 64 bit system, as we
still have all our systems installed as 32 bit system.

If you can _not_ start the binary directly by calling 

./arm-eCross-eabi-gcc 

from within 

~/arm-eCross-eabi/bin


then please call


ldd ~/arm-eCross-eabi/bin/arm-eCross-eabi-gcc  

and send me the output. I can than tell you which libraries are missing
on your system and should be installed.

Best regards,

Ole Reinhardt
