[Xenomai-help] Userland-compile error

[Vikram Dhillon]

Hi all,

I recently compiled and installed a xenomai patched kernel but I am
currently having some issues compiling sample code that came with the
xenomai kernel. So here's what is happening:

=================================================================================================
root@domain.hid# make
XENO=/usr/xenomai/ KSRC=/usr/src/linux-2.6.38.8-xenomai/
--xeno-cflags is deprecated, use --skin=name --cflags instead
--xeno-ldflags is deprecated, use --skin=name --ldflags instead
gcc -DCONSUMER -I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -Wall
-Werror-implicit-function-declaration -pipe -D__XENO__
-I/usr/xenomai/include/posix    -Wl,@/usr/xenomai/lib/posix.wrappers
-L/usr/xenomai/lib -lpthread_rt -lxenomai -lpthread -lrt   -Xlinker
-rpath -Xlinker /usr/xenomai/lib  satch.c   -o satch
/usr/bin/ld: /tmp/ccLV0g8I.o: undefined reference to symbol
'pthread_cancel@domain.hid'
/usr/bin/ld: note: 'pthread_cancel@domain.hid' is defined in DSO
/lib/i386-linux-gnu/libpthread.so.0 so try adding it to the linker
command line
/lib/i386-linux-gnu/libpthread.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [satch] Error 1
=================================================================================================


Linker issue here, the program satch in posix directory won't compile,
first change in the posix makefile:
=================================================================================================
CFLAGS=-DCONSUMER $(shell $(XENOCONFIG) --skin=posix --cflags) $(APP_CFLAGS)
LDFLAGS=$(shell $(XENOCONFIG) --skin=posix --ldflags) $(APP_LDFLAGS)
=================================================================================================


Then, the program still doesn't compile so I actually had to remove
the lpthread switch in compiling:
=================================================================================================
vikram@domain.hid$ gcc -DCONSUMER
-I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -Wall
-Werror-implicit-function-declaration -pipe -D__XENO__
-I/usr/xenomai/include/posix   -Wl,@/usr/xenomai/lib/posix.wrappers
-L/usr/xenomai/lib -lpthread_rt -lxenomai -lrt   -Xlinker -rpath
-Xlinker /usr/xenomai/lib  satch.c   -o satch
vikram@domain.hid$ ls
Makefile  Makefile~  README  satch  satch.c
vikram@domain.hid$ ./satch
Xenomai: binding failed: Operation not permitted.
=================================================================================================

Can anyone tell me what is causing the issue here? Thanks!

This is a strange error, are you sure you are not mixing a 64 bits
toolchain with 32 bits libraries? Did xenomai compilation run correctly
otherwise? Do xenomai tests run, such as latency for instance?

This one usually means that you are not running the example as root user.

Yes, the compile and latency tests actually work just fine, I can
execute them, the error occurs when I try to compile a program from
the examples or something that I wrote. Don't worry about the second
error, that was just to demonstrate that after removing lpthread from
compile switches, the program compiles. I'm using Ubuntu 12.04 if that
provides any help, the debian package xeno-config also gives that
deprecated error so that may just be a problem with the debian
package.

You do not answer all my questions. What machine are you running? Is it
an x86_64 or a 32 bits machine?

If you install xenomai from sources, you should not install debian
package. You will have conflict between the two.

I have a 32-bit machine. Even after removing the debian package for
xeno-config, I have the same error.

You should remove all xenomai debian packages.

Things you can try:
- try and compile a simple example not using xenomai, calling
pthread_cancel and linking it with -lpthread, passing -Wl,-t on gcc
command line to see what libpthread.so is used.
- when you compile xenomai, look at how for instance cyclictest is
compiled, and see if the flags used to compile your examples are the same.
