gcc-4.7-20111022 fails to build on PA-RISC

Hello list,

For the first time I tried building gcc on PA-RISC so I configured with 
the following lines:

jimis@dingo:~/dist/src/objtmp-gcc$ export 
LD_LIBRARY_PATH=/opt/cfarm/gmp-latest/lib/:/opt/cfarm/mpfr-latest/lib/:/opt/cfarm/mpc-latest/lib/
jimis@dingo:~/dist/src/objtmp-gcc$ ../gcc-4.7-20111022/configure 
--prefix=/home/jimis/dist/src/tgt-gcc-4.7-20111022/ 
--enable-checking=assert,misc,runtime,rtl,df 
--with-gmp=/opt/cfarm/gmp-latest --with-mpfr=/opt/cfarm/mpfr-latest 
--with-mpc=/opt/cfarm/mpc-latest CFLAGS="-O -g"


After some time I got the attached error, unfortunately it's in some part 
of gcc in C++. Since I'm not coming to terms with the language could you 
please help me on this one? Am I missing something obvious?


Thanks in advance,
Dimitris

Hello again,

I tried disabling precompiled headers for libstdc++ (thanks apinski for 
pointing this) and now the build fails while trying to build atomic.o. Any 
ideas? Please take a look at the error message in the attached file. The 
culprit seems to be the following:

/usr/include/bits/pthreadtypes.h:34:8: error: no matching function for 
call to '<anonymous struct>::._3(const volatile __atomic_lock_t&)'



Thanks,
Dimitris

This looks as though it's a problem with how we used pthread_mutex_t,
which I changed a few days ago and that might have fixed it.

You could try making this change in libstdc++-v3/include/std/mutex (or
wait for the next 4.7 snapshot)

-    __native_type  _M_mutex = __GTHREAD_MUTEX_INIT;
+    __native_type  _M_mutex;

   public:
     typedef __native_type*                      native_handle_type;

 #ifdef __GTHREAD_MUTEX_INIT
-    constexpr mutex() : _M_mutex(__GTHREAD_MUTEX_INIT) { }
+    constexpr mutex() = default;
 #else

Please let me know if that helps.

What does the definition of _pthread_fastlock on line 34 of
/usr/include/bits/pthreadtypes.h look like?

Don't worry, I foudn the definition on an hppa-linux machine, and can
reproduce the problem even with the latest std::mutex code

e.g.

typedef volatile struct {
    int lock[4];
} __attribute__ ((aligned(16))) __atomic_lock_t;

struct _pthread_fastlock
{
    __atomic_lock_t __spinlock;
};

typedef struct {
    struct _pthread_fastlock lock;
} pthread_mutex_t;

struct mutex {
  pthread_mutex_t m = { };
  mutex() = default;
};

int main()
{
  mutex mx;
}

The problem is that the mutex contains a volatile type and can't be
copied by the implicit-declared copy constructor.

I'll have to look into this further tomorrow to see if it's a G++
problem or something we need to work around in the library.

Let's continue this thread on the libstdc++ list instead - it's a
problem we'll have to fix.

Hi Jonathan,

I tried applying the latest changes from svn to mutex, but it stills fails 
to build.
