[Xenomai] Installing xenomai libraries ARM OMAP4460

[Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

Hi All,

Having installed Xenomai, I am wanting to test Xenomai.

If I understood the guide correctly under the title "Installing the Xenomai
libraries and tools", I would need to compile the libraries as well as the
test apps. For that I need to do by executing the command below in the
xenomai_root which in my case is xenomai_root=xenomai-3. However, the
configure file is not found. I am totally confused of what have I done
wrong? Any helps/advise would be appreciated.

$xenomai_root/configure CFLAGS="-march=armv4t" LDFLAGS="-march=armv4t" \
  --build=i686-pc-linux-gnu --host=arm-none-linux-gnueabi- --with-core=cobalt

Thank you

Lim

-march=armv4t works for ARM processors using the ARMv4T architecture
revision. The cortex A9 in an omap4460 uses the ARMv7 architecture
revision. So, you should pass -march=armv7 instead, or -mcpu=cortex-a9

the argument to the --host option should not include the leading
dash.

the variable xenomai_root should probably be an absolute path. And
note that if you downloaded xenomai-3 from its git repository as
opposed to its latest archive, you also need to call autoreconf -i
to create the configure scrippt.

Could also be -march=armv7-a

If the toolchain you use has no support for floating point, you
probably also want to use a toolchain with floating point support,
such as the Denx ELDK 5 toolchain for the armv7a-hf architecture, or
the Linaro toolchain.

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

I downloaded ipipe-ipipe-core-3.18.20-arm-5 and tried to run ./configure,
file not found as well. In addition, I checked in the ./scripts directory,
none of the configure or autoreconf exist. It is not the right source I
have downloaded? Any comments please.

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

Thanks, I managed to get .configure by executing autoreconf -i. However, I
am facing another problem.

$xenomai_root/configure CC=arm-linux-gnueabihf- CFLAGS="-march=armv7-a
-mfpu3=vfp" LDFLAGS="-march=armv7-a -mfpu=vfp3" --build=i686-pc-linux-gnu

I have my Linaro toolchain set as
CC=/home/qws/linaro-gcc/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-
and by setting the --host=${CC}, the configure refuse to recognise it. I
tried without the suffix. See below.

qws@qws-MacBookPro:~/PandaBoard-ee/xenomai-3$ $xenomai_root/configure

Any idea how to set the --host for Linaro toolchain?

Thank in advance.

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

Hi Gilles and all,

Having had bad experience with Linaro toolchain, arm-linux-gnueabihf-, I
now change to arm-none-linux-. Unfortunately, I still get the same error
messages.

checking for arm-none-linux-gcc... arm-none-linux-gnueabi-
checking whether the C compiler works... no
configure: error: in `/home/qws/PandaBoard-ee':
configure: error: C compiler cannot create executables
I have googled for hours, but couldn't get anything positive.

Please help.

Thank you

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

Hi Gilles,

I managed to get autoreconf -if to work, and advanced to compiling the
xenomai. However, yet not to the end. I got the following error. Then I
switch xenomai-gch. The same error as well. Hence, I changed the CC to
Ubuntu arm-linux-gnueabihf package. The same error too. The errors are as
follow.

checking for ARM machine... configure: error: Selecting a machine with
--enable-arm-mach is mandatory

and the command is  ./configure CFLAGS="-march=armv7-a -mfpu=vfp3"
LDFLAGS="-march=armv7-a -mfpu=vfp3" --with-core=cobalt --enable-smp
--enable-pshared --build=x86_64-linux-gnu --host=arm-linux-gnueabihf

if I added --enable-arm-mach, I get error messages "checking for ARM
machine... configure: error: Invalid machine selected: "yes"".

Googles don't seem to get any positive resolution. Appreciate any comments.

Thank you

You are trying to compile an outdated version of Xenomai, Xenomai
version 2.5 or earlier. You can have access to the installation
instructions for that particular version in the sources (the file is
named README.INSTALL at the top of the sources tree), or on the
website, using the URL:

http://xenomai.org/documentation/xenomai-2.5/README.INSTALL

for instance, if installing the version 2.5. Replace 2.5 with the
version you are actually installing.

I use Xenomai-3 of which I use patches namely
kernel/cobalt/arch/arm/patches/ipipe-core-3.18.12-arm-4.patch patched the
kernel 3.18.12. And under Xenomai-3, I autoreconf -fi to create a configure
file and finally make it xenomai libs and test apps. Under the installed is
has two directory, dev and usr. Under the usr/ it has xenomai/bin, etc.

Have I missed out anything? in terms getting it the test apps as well as
the related device files to work.

So, you got passed the error "Selecting a machine with --enable-arm-mach
is mandatory" finally? It is a bit hard to follow your progress.

To see if xenomai is installed correctly, see:
http://xenomai.org/installing-xenomai-3-x/#Testing_the_installation

For the device files, see Lennart answer here:

So, you are not compiling xenomai-3. xenomai-3 does not have an
--enable-arm-mach option. This contradicts what you said
above. But then I do not see how you could compile the I-pipe patch
for Linux 3.18, because Xenomai 2.5 or earlier do not compile with
Linux 3.18. This all looks like nonsense to me.

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

I had tried compiling 4 versions of xenomai at on the period of time.
xenomai-gch on Pandaboard, xenomai-gch on i686 and xenomai-3 on i686 and
ipipe-core on i686 because of the latency and dev issues.

The xenomai-gch which I presumed It was the latest You are right about
that. Apologies for the confusion.

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

Having no lucks, I switched it to ipipe-ipipe-core-3.18.20-arm-5.tar.bz2
which I presume it has all the patches required. One thing puzzled me when
advanced to the second command below. I didn't see the Cobalt listed in the
menuconfig. Is it right? but after succeeded compiling it, the cat
include/generated/utsrelease.h | awk '{print $3}' | sed 's/\"//g' show the
kernel version is like 3.18.20-ipipe. Can anyone explain when Cobalt is not
listed in menuconfig, please? After installing kernel 3.18.20-ipipe, dmesg
| grep -i xenomai show nothing, but dmesg | grep -i ipipe get the
following. I had t assume it is working now. With ipipe-core-3.18.20, how
would I produce xenomai/ipipe libs and test apps?

Appreciate any comments please?

The configure script may be found in Xenomai sources tarball, it is
not added by the I-pipe patch. You will need autoreconf if
installing xenomai from a git repository checkout. autoreconf is not
part of Xenomai sources distribution, it is a tool which should be
provided by your distribution. For other requirements, see:
http://xenomai.org/installing-xenomai-3-x/#Installing_the_Xenomai_libraries_and_tools

If you have no experience building packages from sources using the
autotools, I suggest you look for general information about that
before starting and compiling xenomai, and asking question to this
list every time something is missing.

Hi Gilles,
I have switched to xenomai-gch and natively compiling on Pandaboard. See
the command below. The --build, --host have no effect since it is not
cross-compiling. However,  I face a problem here, it complains that
"checking for ARM machine... configure: error: Invalid machine selected:
"armv7"
". I have tried arm, arm-linux, arm-linux-gnueabihf, and blank. None of
them work. Appreciate any comments please.

Further search found that in configure.in, it has only omap3 defined. I

Re: [Xenomai] Installing xenomai libraries ARM OMAP4460

[vibnwis]

I managed to proceed by setting --enable-arm-mach=omap3 even though my
board is of omap4460.

./configure CFLAGS="-march=armv7-a -mfpu=vfp3" LDFLAGS="-march=armv7-a
-mfpu=vfp3" --with-core=cobalt --enable-smp --enable-pshared
--build=x86_64-linux-gnu --host=arm-linux-gnueabihf --enable-arm-mach=omap3

However, by executing make install, it ended with

Makefile:393: recipe for target 'librtdk_la-assert_context.lo' failed
make[2]: *** [librtdk_la-assert_context.lo] Error 1
make[2]: Leaving directory '/home/qws/PandaBoard-2/xenomai-gch/src/rtdk'

make[1]: Leaving directory '/home/qws/PandaBoard-2/xenomai-gch/src'
