Hello I tried to compile Xrootd (from the HEAD) on Fedora Core3 using gcc 3.4.2 and './configure --build=debug'. It fails with the following error: Compiling XrdClientAbs.cc In file included from /usr/lib/gcc/i386-redhat-linux/3.4.2/../../../../include/c++/3.4.2/sstream:640, from ../XrdClient/XrdClientDebug.hh:23, from XrdClientAbs.cc:17: /usr/lib/gcc/i386-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/sstream.tcc: In member function `virtual typename std::basic_stringbuf<_CharT, _Traits, _Alloc>::int_type std::basic_stringbuf<_CharT, _Traits, _Alloc>::overflow(typename _Traits::int_type)': /usr/lib/gcc/i386-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/sstream.tcc:104: error: expected unqualified-id before '(' token gmake[4]: *** [../../obj/i386_linux26_dbg/XrdClientAbs.o] Error 1 I could fix the problem by modifying ./src/XrdClientDebug.hh, adding #undef min #undef max before the include statements (it has to be before #include <sstream>), but I don't understand why I have to do this. Is this something that has to be fixed ? Cheers, Wilko
