Compiling problem

mhoroub · July 6, 2011, 2:48pm

Hi
I have checked-out the latest root version 5.30.00 by typing
svn co root.cern.ch/svn/root/tags/v5-30-00 root

then

sudo ./configure
it went ok, then
sudo make

and it crashed after sometime(see the message below)

Hi,

On which platform? Using which compiler?

If you do not need xrootd, add --disable-xrootd to the call to configure.

Cheers,
Philippe.

mhoroub · July 7, 2011, 7:53am

Hi,

gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)

Axel · July 7, 2011, 3:05pm

Hi,

looks like these object files were built with an incompatible compiler. I’d run make distclean; make.

Cheers, Axel.

Hi,

I am getting the same exact error when trying to compile root v5-30-00-rc2.

I tried a distclean and then make again but no luck.
Using Ubuntu 10.04LTS and gcc version 4.4.3.
I appreciate any help. Thanks

Hi,
I too have a similar problem. My system configuration is:
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)

zkohley · July 14, 2011, 11:45am

While it is not an absolute fix:

Philippe’s suggestion of disabling xrootd did work and allow me to compile root.

Andrey_Pozdnyakov · July 17, 2011, 9:48pm

Hi,
I have exact same problem.

Could you tell what is xrootd for?

pcanal · July 19, 2011, 7:42pm

See xrootd.slac.stanford.edu
It is also used by PROOF in some configurations.

Cheers,
Philippe.

Hi,

sorry for digging out that old thread, just stumbled upon the solution. I suppose your error is caused by this bug in the xrootd build system: savannah.cern.ch/bugs/?81746

The test for gcc’s atomics fails on some platforms (e.g. 64 bit PowerPC).

As a quick workaround you can comment out the ill-defined atomics and return to the standard in src/xrootd/src/XrdSys/XrdSysAtomics.hh or simply exhange the #ifdef by #ifndef.

 /*#ifdef HAVE_ATOMICS
 #define AtomicBeg(Mtx)
 #define AtomicEnd(Mtx)
 #define AtomicAdd(x, y)     __sync_fetch_and_add(&x, y)
 #define AtomicCAS(x, y, z)  __sync_bool_compare_and_swap(&x, y, z)
 #define AtomicDec(x)        __sync_fetch_and_sub(&x, 1)
 #define AtomicDTZ(x)        if (!(__sync_fetch_and_sub(&x, 1))) AtomicFAZ(x)
 #define AtomicFAZ(x)        __sync_fetch_and_and(&x, 0)
 #define AtomicGet(x)        __sync_fetch_and_or(&x, 0)
 #define AtomicInc(x)        __sync_fetch_and_add(&x, 1)
 #define AtomicISM(x, y)     AtomicCAS(y, AtomicInc(x), x)
 #define AtomicSub(x, y)     __sync_fetch_and_sub(&x, y)
 #else*/
 #define AtomicBeg(Mtx)      Mtx.Lock()
 #define AtomicEnd(Mtx)      Mtx.UnLock()
 #define AtomicAdd(x, y)     x += y
 #define AtomicCAS(x, y, z)  if (x == y) x = z
 #define AtomicDTZ(x)        if (!(x--)) x = 0
 #define AtomicDec(x)        x--
 #define AtomicFAZ(x)        x; x = 0
 #define AtomicGet(x)        x
 #define AtomicInc(x)        x++
 #define AtomicISM(x, y)     if (y == x++) y = x
 #define AtomicSub(x, y)     x -= y
 /*#endif*/
 #endif

It would be helpful to post your platform.

Regards
Kwyjibo

Dear Kwyjibo,
thank you very much. All my machines compiled the 5.30 ok, but one. Finally, we found that this is 64bit one and the problem was immediately solved after applying your recommendation.
