I attached the modifications that are needed in gcc3strm.cxx to compile with gcc 3.4.0. There are 2 problems. One is that I could not find any trace of ostream& operator<< (ostream&,const streampos&); in the gcc 3.3.1 or the gcc 3.4.0 header files. However it is in cint/lib/gcc3strm/iostrm.h and of course in gcc3strm.cxx The second problem is more fundamental. In gcc 3.4.0, streamoff is defined as (include/c++/3.4.0/bits/postypes.h) #ifdef _GLIBCXX_HAVE_INT64_T typedef int64_t streamoff; #else typedef long long streamoff; #endif in turn int64_t is platform dependent. In particular, on my node int64_t is typedef to an int. In gcc 3.3.1, streamoff was a long. This leads to the compilation error: cint/src/gcc3strm.cxx: In function `int G__G__stream_6_4_0(G__value*, const char*, G__param*, int)': cint/src/gcc3strm.cxx:149: error: 'const class std::fpos<mbstate_t>' has no member named 'operator long int' As a quick fix, I simply replaced the implementatio of the wrapper so that it does not do an explicit call to the operator long: const fpos<mbstate_t>*pos = (const fpos<mbstate_t>*)(G__getstructoffset()); G__letint(result7,108,(long)(*pos)); instead of G__letint(result7,108,(long)((const fpos<mbstate_t>*)(G__getstructoffset()))->operator long()); Of course, this is fundamentally wrong, since on a 64 bit platform, this will truncate the long long into a long. I am not sure what would be good solution (theoritically, it would require to make sure that the dictionary for fpos<mbstate_t> is different (long vs long long) on the appropriate platforms). git-svn-id: http://root.cern.ch/svn/root/trunk@9367 27541ba8-7e3a-0410-8455-c3a389f83636
