Dear Rooters, I've ported ROOT to glibc 2.2. Due to the change of several libc data types (notably fpos_t which changed from an unsigned long to a struct) the port took a bit longer than expected (one night :-)). In addition the g++ that comes with RH 7.0 is fairly buggy (see http://gcc.gnu.org/ml/gcc-bugs/2000-10/ for bugs I had to submit). Before understanding the compiler problems, finding work arounds and finding a safe optimization level quite some rebuilds were needed (it helps to have a new private 6 CPU PIII Xeon HP Netserver though). So the bottom line is ROOT compiles and works with -O, but not with -O2. It looks safe to also stay away from -O2 for your own apps. Get the latest version from CVS and build with: ./configure linuxegcs. Cheers, Fons. -- Org: CERN, European Laboratory for Particle Physics.
