Hi,

We are currently porting some of our vxWorks  xenomai (copperplate) APIs we use in our application to
Posix (cobalt I guess). We have started with the VxWorks "tasks" but it seems that we're getting strange behavior on
The remaining VxWorks APIs when used from the POSIX generated tasks (threads is the right word in posix) e.g. MsqQRecv function gets segfault but when it is used From a VxWorks generated task it works fine.
I understand from the comments in code it should work but I was wondering if there are known issues.

We are using currently xenomai 3 rc-6 (I saw there were fixes in xenomai 3.0.2).

Thanks in advance,
Alex Plits.

Well, if you do not know whether you are using Cobalt or Mercury, we
can not know it for you...

Could you send a self-contained, simplest possible test case which
causes the problem for you, that we can test on the latest Xenomai
release to see if the problem has not been already fixed?

Attached code that is ripped from xenomai examples and initiates 2 threads using posix api then uses VxWorks MsgQ to communicate.
Please advise if this code works as expected -  it seems that when we use WAIT_FOREVER flag we have an issue.

Sorry in advance for the #ifdef's and comments in code -
Thanks,
Alex Plits.

For the record, 3.0-rc6 won't work properly with --enable-pshared
setups. For sane shared processing involving multiple copperplate-based
APIs (such as VxWorks), you do need 3.0.2.

[Alex Plits] 
We have configured --enable-pshared on xenomai 3.0.2 and now compiling empty application (just empty main routine) using non posix skin e.g. vxworks or even alchemy causes the 
"Bus error" in runtime(see below). Removing --enable-pshared bootstrap completes successfully.

# ./posixvx --trace=1
--  xenomai_init() running
--  cobalt->init()
--  connected to Cobalt
--  memory locked
--  memory heaps mapped
--  boilerplate->init()
--  copperplate->init()
Bus error

The output of posixvx --dump-config is needed as well.

[Alex Plits] 
See below --dump-config , working to get the gdb backtrace.

# ./posixvx 
Bus error

We're not getting the symbols correctly although everything seems to be in place (debugging info, correct symbol file loaded etc.)
According to the following memory mapping dump and gdb address backtrace it seems the issue is in cooperplate but again we can't seem
to find the corresponding symbol/function.

GDB
#0  0xb6fc455c in ?? ()
Cannot access memory at address 0x6e6f6e58
