 Hi all,I'm trying to install Xenomai on ARM sam9g20.
I compiled the kernel with Xenomai patch and create the filesystem with buildroot.
crosscompiling Xenomai with these commands:

fede@domain.hid$ ./configure --host=arm-linux-gnueabi --enable-arm-eabi --enable-arm-mach=at91sam9 --disable-arm-tsc --enable-static
make DESTDIR=/home/fede/foxg20/kernel/l/ install
I copy the file in the arm-filesystem
but when I try to run / usr / Xenomai / bin
for example, the file latency
get:
./latency
-sh: ./latency:not found
any suggestions?

Could you try compiling with dynamic libraries, to see if
--enable-static could be the issue? Also, you should try running make
DESTDIR=/path/to/buildroot/nfsroot install to install the binaries.

Of course /path/to/buildroot/nfsroot is not meant to be used literally,
you were supposed to replace it with the path where you installed
buildroot on your system.

And please do not forget to CC the mailing list.

yes yes
I used the command: sudo make DESTDIR=~/buildroot/output/rootfs install
I also put directly on memory card
sudo make DESTDIR=/media/rootfs/  install
but nothing has changed
you may blame the shared library in the /rootfs/lib generated by builroot?

Usually
./latency: not found
means that the loader that would be ld-linux.so.3 with glibc, or
something a bit different with uclibc is not found in the filesystem. If
you have ldd on the filesystem, you may try it. Or run readelf on the
host and see that all the libraries are found in the filesystem.

Are you sure you are not mixing the outputs of two different toolchains,
or something along the line?

Hm... I see you running "make", but where to you tell it to use a
cross compiler?

> ./latency

Try running "file ./latency" and verify that this actually an ARM
binary - I guess you used the native compilers, and your ARM system
refuses to run x86 binaries.

Best regards,

Wolfgang Denk

The --host argument passed to configure is used as a compiler prefix.
