arm-linux-gcc command not found

Forum: Linux
Mohan Saini 
Hi All.
I am getting an error arm-linux-gcc command not found while i am giving
command make zImage for mini2440. I have already given correct path as
export PATH=$PATH:/opt/FriendlyArm/toolschain/4.4.3/bin. it shows correct
path when i type echo $PATH but don't know what is the issue please help.

genpix 
may be you forgot ~ ?
is it really 
/opt/FriendlyArm/toolschain/4.4.3/bin ?
is it possible that it's actually at
~/opt/FriendlyArm/toolschain/4.4.3/bin ?

did you try to execute just "arm-linux-gcc" ?

Mohan Saini 
Yes i have tried with arm-linux-gcc it shows command not found!!

Reggie 
find where it actually is and put that in the export PATH= command instead?

Did you unpack the toolchain as root?

Juergen Beisert 
Check if you have installed the correct system libraries. Run the "ldd"
command on the "/opt/FriendlyArm/toolschain/4.4.3/bin/arm-linux-gcc"
executable and see what it tells you.
I guess a 32 bit versus 64 bit issue.

Mohan Saini 
Hi Sir,
        The previous issue has been resolved i was not unpacking toolchain
in root. But now i am getting error while i am making zImage as.

now why this error is there?

Mohan Saini,
could you please tell me how you solved that toolchain problem as you said
in your last comment here.
I am facing with same problem:arm-linux-gcc command not found.
I may also say that i did not find such a file in the necessary place.
So i eould be grateful if by anychance you could zip and mail me the folder
that contains the -gcc xecutable file.

Reggie 
export ARCH=arm

These are all relatively standard things that you might expect to set
before cross compiling a kernel, they should be very simple to find via
google.

Thanks,
i did it and
now i am getting a new error.

can anyone help me with this?

Reggie 
There are so many things wrong with whatever it is you're trying to do.

Try giving more information about what you're attempting.  We've gone from
compiling a kernel for the 2440 to compiling uboot (I think) for something
else, a xilinx chip, at least that's what it looks like.

Prateek Sahu 
i was following this link
http://www.wiki.xilinx.com/Zynq+Base+TRD+14.4
for setting up xilinx zynq board.
when i got stuck with the linux kernel make directory (7th section of the
link)
while using this command $make ARCH=arm uImage

while searching for that i came across this wiki page
http://www.wiki.xilinx.com/Build+Kernel
In this,under the heading linux for zynq ap soc
make ARCH=arm UIMAGE_LOADADDR=0x8000 uImage
command prompted error of Ygcc being not found

I searched and set the PATH for it correctly, and then when i tried 'make'
i got this error
prateek@ubuntu:/host/xilinx_example/ZYNQ_TRD_HOME/linux-xlnx$ make ARCH=arm
UIMAGE_LOADADDR=0x8000 uImage

while searching for this error i came across this video
http://www.youtube.com/watch?v=wlXbeqtW0hI
at 3:07 there is a set of instructions, for the command $make ARCH=arm
uImage
i got the error of arm-linux-gcc not found.which i posted it here.
later,before your reply,i got a .tar.gz file containing those executables.
so i cross-compiled that folder and set the path properly.
then when i tried
$make command,i got the error that i had just posted.
does this make any sense now??

Prateek Sahu 
i am sorry,i have missed a part.
after the Ygcc error when i set the path and tried make i got this error
too

 it has something to do with xilinx_devcfg.c file. i have looked into that
error with great detail and even tried out measures but with no avail.and
hence i proceeded with the $make ARCh=arm UIMAGE_LOADADDR=0x8000 uImage
command and proceeded with te error list

Juergen Beisert 
Why do you ask questions about Xilinx? Here we are talking about
FriendlyARM hardware...

Prateek Sahu 
I just came across an error whose google results brought me to this page.
when reported,one of the contributers asked to explain what exactly was i
trying to do.hence i enumerated my problems,which has to deal with xilinx
too.i am sorry,i am a newbie and hadnt really thought that i could just
post FriendlyARM queries.i was just hoping for help here.

srinivas 
hai all,
I have arm-linux-gcc-4.4.3.tgz and linux-2.6.32.2-mini2440_20110413.tgz.

Juergen Beisert 
Read the error message carefully: "arm-linux-gccgcc" :)

Try with "CROSS_COMPILE=arm-linux-" instead.

srinivas 
I tried as you said it's compiled.For building image this is the command 
make ARCH=arm CROSS_COMPILE=arm-linux- zImage. 
I think there is a another method like export ? what is that method.
Thanking you.

srinivas 
sorry sorry.. I am getting below error

what is this error,how to solve it.

Juergen Beisert 
Read about how "bash" is working

srinivas 
please tell me the process of cross compilation and building image for arm
for kernel linux-2.6.32.2 with arm-linux-gcc.

Juergen Beisert 
Sorry, I only can help you with my own kernels for the Mini2440. I never
worked with the linux-2.6.32.2 you mentioned.

srinivas 
I think kernel is not matter,the above process i mentioned is same for all
linux kernels.please tell me about that process with any linux kernel with
arm-linux-gcc cross compiler.I am using ubuntu 12.04 os.so please help.

Juergen Beisert 
> [...] the above process i mentioned is same for all linux kernels

Your are right. The correct process for all kernels is to just fix the
error.

Harsh Pandey 
It can be because you have not set the toolchain path to the bashrc file.
I would suggest you follow this link:
 https://developer.ridgerun.com/wiki/index.php/Code_Sourcery_ARM_toolchai...
Very briefly explained to install the toolchain to the required path along
with all the dependecies.
