Hello,
I have a problem installing GNU-C++ on Ultrix.
An error (namely >>undefined debug_tree<<) occurs and I do not know
how to eliminate it.
I installed  GNU-Bison Vers. 1.9 and configuered GNU-C on a >>decstation<<
and installed it in >>/usr/local<<. It seems to work.
I configured G++ also as runnnig on a >>decstation<< and set switches for
using >>ENCOFF-ENCAPSULATION<<, whatever this will be.
Unfortunetly there is that error.
-
This my systems equipment:
        machine:        DEC 3100
        OS:             Ultrix 4.1
        C-compiler:     GCC vers. 1.39 and bison 1.14
        C++-compiler:   G++ vers. 1.39.0
-
Did anybody have the same problems and managed to get G++ running?
Or does anybody know how to handle this error?
-
Everybody who has some hints for solving this problem, send them to me,
as detailed as possible, please.
Thanks in advance,
