Following up on my previous email, I think the "make modules_install" command
is trying to install to the host system, not the file system I'm specifying as
the target directory.
This is everything I've done so far:
export PROJECT=openctl
export PRJROOT=/home/tbj/srcroot/${PROJECT}
export PRJAT91=${PRJROOT}/at91
export PRJAT91_KERNEL=${PRJAT91}/kernel/3.2.46-rt67
export PRJAT91FS=${PRJAT91}/rootfs
echo Setup the compiler for cross-compilation
unset ARCH
ARCH=arm
export GYP_DEFINES="target_arch=arm"
export CC=arm-linux-gcc
export CXX=arm-linux-g++
export AR=arm-linux-ar
export CC_host=gcc
export CXX_host=g++
./configure --prefix=$PRJAT91FS/opt --with-linux-dir=$PRJAT91_KERNEL/headers
--enable-generic=yes --enable-8139too=no --host=i386
--target=arm-none-linux-gnueabi-
make clean
make DESTDIR=$PRGAT91FS ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make modules DESTDIR=$PRGAT91FS ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make install ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- DESTDIR=$PRGAT91FS
No problems until:
Make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- DESTDIR=$PRGAT91FS
INSTALL_MOD_PATH=$PRGAT91FS modules_install
...
An endless list of warnings....
...
FATAL: Could not open /lib/modules/3.2.46-rt67/modules.dep.temp for writing:
Permission denied
make[1]: *** [_emodinst_post] Error 1
make[1]: Leaving directory
`/home/tbj/srcroot/openctl/at91/kernel/3.2.46-rt67/headers'
Can anyone see what I'm doing wrong?

IIRC, the --with-linux-dir option cannot cope with relative paths nor ~
prefixed paths. Specify the absolute path from / instead.

Subject: [etherlab-users] Cross Compile for ARM
I'm trying to cross-compile the EtherCAT master for an ARM board. I
successfully built a Linux RT Prempt kernel for the device. On my development
machine, the source tree where I built the kernel is at:
~/srcroot/linux/linux-3.2.46
I moved into the EtherLAB directory and issued:
./configure --host=arm-linux --enable-generic
--with-linux-dir=~/srcroot/linux/linux-3.2.46
The result is:
No configured Linux kernel sources in ~/srcroot/linux/linux-3.2.46/
But I just built a kernel there. Is there something I have to do to the source
tree to get it ready to build the ethercat master?
Thanks in advance,
Tome
