ethtool: Command not found

I am cross-compiling Linux-2.6.31.5 for my Target board.
My target board is a customized board based on MPC8548E processor from Freescale.

I am able to port the Linux onto target and run my applications.

The problem is, the default speed by which the board is working is:
10 Mbps, Full Duplex.

So, I wanted to change it to 100 Mbps, Full Duplex.

I remembered ethtool usage on the host system and tried the same on the target as:

ethtool -s eth1 speed 100 duplex full autoneg off;

But the error message displayed is:
ethtool: command not found.

Please get me a solution for this.

Note:
I am trying to use ethtool command on the target, not the host.

Then it's not in your $PATH (prefix path) or its not installed (install it).

Hi unSpawn,
Thanks for the reply.

Sorry for my English.


It is already installed on the host. But I am trying to use it on the Target. I need to install it in NFS Server path, so that I can access that command on the target.

To install it the steps given are:
./configure
make
make install

When I gave ./configure command it gave me the following error:

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether to enable maintainer-specific portions of Makefiles... no

checking whether the C compiler works... no
configure: error: in `/home/User1/MYPROJECT/MYDIRECTORY/ETHTOOL/ethtool-3.10':
configure: error: C compiler cannot create executables
See `config.log' for more details

Could you please suggest a solution for this?

Thanks in advance.

No need to apologize, it's just good to be aware. Enough said.

Did you check config.log contents? Have you compiled anything successful before using these settings? If not this could point to anything ranging from missing dependencies, wrong set of flags to mount point flags...

Yes actually I checked the config.log contents. But I didn't understand much. Need to check it again.

Yes I am able to compile all my applications and run them on the target successfully with this cross-compiler.
I think there is no problem with the cross-compiler.

If you have any idea, could you please let me know what are the flags I need to use while compiling?

Thanks in advance.

No, not that many ideas without looking at config.log (attach as plain text file?).
Could it be in requires the kernel source?..

Please Find the Attachment of config.log as text file.

Hi unSpawn,
I found few lines in config.log file which I feel the cause for errors. Please go through the following lines:

/home/User1/MYPROJECT/MYMODULE/BuildrootToolchain_GCC_GPP/host/usr/bin/../lib/gcc/powerpc-buildroot-linux-uclibcspe/4.5.4/../../../../powerpc-buildroot-linux-uclibcspe/bin/ld: cannot find crt1.o: No such file or directory

collect2: ld returned 1 exit status

How can I fix this?

Find the development package concerned. I don't know about the others but crt1.o may be part of glibc-devel?
