building gcc problem on Dec Alpha osf5.0

[Philip Cheng]

I am trying to build gcc on my Dec Alpha running osf5.0

When I used gcc 2.95.2, I got the error

>gcc  -DIN_GCC -DHAIFA	 -g  -DHAVE_CONFIG_H  -o cc1 toplev.o version.o tree.o print-tree.o stor-layout.o fold-const.o function.o stmt.o except.o expr.o calls.o expmed.o explow.o optabs.o intl.o varasm.o rtl.o print-rtl.o rtlanal.o emit-rtl.o genrtl.o real.o dbxout.o sdbout.o dwarfout.o dwarf2out.o xcoffout.o bitmap.o

When I used gcc 3.0, I got the error

>checking for g++ that will successfully compile libstdc++-v3... configure: error: please upgrade to GCC 3.0 or above
>make[1]: *** [configure-target-libstdc++-v3] Error 1
>make: *** [bootstrap] Error 2

Anyone knows how to solve the problem?  I just need to build gcc on my
Alpha and I don't care whether it is 2.95 or 3.0.

Did anyone build gcc successfully on osf5.0?  Should I upgrade to osf5.1?

Thanks
