Hi Gilles,

I've done this with the 2.5.2 version and I have had the same problem. 
It is the consequence of another one earlier in the compilation process.
After the xenomai configuration for NIOS II:
$ ./configure --host=nios2-linux

the generated src/include/xeno_config.h configuration file has 
CONFIG_XENO_FASTSYNCH not configured:
...
/* config */
/* #undef CONFIG_XENO_FASTSYNCH */
...

If you make the compilation, it fails on the src/skins/common/sem_heap.c 
compilation.
You have in this files 2 similar functions
line 100: static void xeno_init_sem_heaps_inner(void)
and
line 118: void xeno_init_sem_heaps(void)

There is a mismatch in the src/skins/common/sem_heap.h file according to 
the CONFIG_XENO_FASTSYNCH definition (during Xenomai configuration).
In this case it conflits with the macro #define xeno_init_sem_heaps() 
line 9 in the src/skins/common/sem_heap.h file and the void 
xeno_init_sem_heaps(void) in the src/skins/common/sem_heap.c

I don't know what in the right correction to do in the 
src/skins/common/sem_heap.h file according to the CONFIG_XENO_FASTSYNCH 
definition.

If I suppress the line 9 (#define ...) in the 
src/skins/common/sem_heap.h file, it compiles until problems for 
src/testsuite/unit  tool:
cond-torture.c file. Line 56: problem with the  "if else" structure when 
HAVE_PTHREAD_MUTEXATTR_SETPROTOCOL is not defined (the case here).
check-vdso.c compilation: in the src/testsuite/unit/Makefile.in file, 
the @CONFIG_XENO_FASTSYNCH_TRUE@ controls the check-vdso compilation. it 
is not completely inhibited when CONFIG_XENO_FASTSYNCH is not configured 
(the case here).

I have corrected by hand these 2 problems and Xenomai v2.5.2 is OK on my 
NIOS II board.

Gilles, what is the right modification to make on the 
src/skins/common/sem_heap.h file when CONFIG_XENO_FASTSYNCH is not 
defined during Xenomai configration?

Cheers;

Patrice
