[Xenomai] Error "field ‘pse51_si’ has incomplete type" in syscall.h after upgrading Ubuntu Distrib to 13.04

[Marc Le Douarain]

Hello everybody,

I have an application using Xenomai that do no more compile after I have 
recently upgraded from Ubuntu 12.10 to 13.04

Here the error I have in one one file including "phread.h" :
gcc -c tasks.c -o tasks.o -march=i486 ...(custom defines)... 
`xeno-config --skin posix --cflags`
In file included from /usr/xenomai/include/asm/xenomai/syscall.h:23:0,
                  from /usr/xenomai/include/nucleus/trace.h:52,
                  from /usr/xenomai/include/nucleus/system.h:27,
                  from /usr/xenomai/include/asm/xenomai/system_32.h:137,
                  from /usr/xenomai/include/asm/xenomai/system.h:2,

/usr/xenomai/include/asm-generic/xenomai/syscall.h:78:17: erreur: field 
‘pse51_si’ has incomplete type
make: *** [tasks.o] Erreur 1

gcc installed on this version is 4.7.3
My project based on Linux kernel 2.6.38.8 and Xenomai 2.5.6

any one have an idea, on something that could be done...?
else I'm thinking to install an older version in virtual machine to no 
more encounter bad surprises with upgrades !

Many thanks in advance.

You are probably lacking a #include, add the missing include and it
should be fine. Also, Xenomai 2.5.6 and Linux 2.6.38 are really old,
updating is recommended.

Thank for the tip, but I've exactly the same error, with an old little 
"hello" example,
I've included.
Example using native tasks, and that was compiling correctly before 
distrib upgrade...

Bye, bye.

Apparently, you misunderstood, so I am going to try and explain again.
The problematic line of code is "struct siginfo pse51_si", because of
the toolchain update, the header defining "struct siginfo" was included
in another header, so we made the mistake not to include this header at
the time of xenomai 2.5.6 (which was two and a half years ago). But this
code disappeared in latest versions of Xenomai. So, you have two solutions:
- add the missing #include directive in Xenomai 2.5.6 sources
- or upgrade to Xenomai 2.6.2.1 which is the latest version.
