Great. Thanks.

OK, not to worry. powerpc64 is after all an "experimental"
distribution. I'm not even sure it will ever be released.

Remeber, you have to do "trusted X forwarding", that is, "ssh -Y ...".

No. It's a problem in CINT however.

The problem is, that CINT does know how to deal with functions of the
type
f(const char* format, ...)
on mips - it needs to be told how to do that. In the file
"cint/inc/G__ci.h" near line 1550, try to change the lines
#elif (defined(__PPC__)||defined(__ppc__))&&(defined(__linux)||defined(__linux__))
/**********************************************
* PowerPC, Linux
**********************************************/
#define G__VAARG_INC_COPY_N 4
#define G__VAARG_PASS_BY_REFERENCE 8
to
#elif (defined(__PPC__)||defined(__ppc__))&&(defined(__linux)||defined(__linux__))
/**********************************************
* PowerPC, Linux
**********************************************/
#define G__VAARG_INC_COPY_N 4
#define G__VAARG_PASS_BY_REFERENCE 8
#elif (defined(__mips)&&defined(linux))
/**********************************************
* MIPS, Linux
**********************************************/
#define G__VAARG_INC_COPY_N 4
#define G__VAARG_PASS_BY_REFERENCE 8
[that is, add the switch on mips/linux]
Can you try to make that change and rebuild? Just make the change and
then run "fakeroot debian/rules binary" - that should be enough.
Thanks.
CINT developers: mips is a 32bit big-endian platform, running Linux and
using GCC. Is it correct to assume that this platform is similar to
powerpc w/Linux and GCC?

Right. Same problem.

The file "na49.root" is generated by the script "geom/geometry.C", and
since that fails, it means that the file is not made, so no biggy.

OK, cool.

OK, that's easily fixed. Just add
ifeq ($(ARCH),linuxmips64)
# Linux with egcs, gcc 2.9x, gcc 3.x
CXX = g++
CXXFLAGS = $(OPT2) -Wall -fPIC
LD = g++
LDFLAGS = $(OPT2)
SOFLAGS = -shared
endif
somewhere near the other "linux*" in Makefile.arch.
Thank you.
Yours,
