[Matrix-SIG] Re: [C++-SIG] CXX (Release 8) and EGCS 1.1.1

[Paul F. Dubois]

I have now learned enough Linux that I installed EGCS 1.1.1 and tried to
compile CXX, but even with some corrections to deal with the std:: problem
and the error you got, I still get internal compiler errors. I will look
into this some more. One correspondent cleverly worked around the errors but
broke the code by removing a virtual behavior. Since the error is in a
virtual function in a templated class, it is at least believable that there
is a compiler error.

g++ -fpic  -I./Include -I./Demo -g  -I/usr/local/beta/dubois/stockpython/inc
lude/python1.5 -I/usr/local/beta/dubois/stockpython/include/python1.5 -DHAVE
_CONFIG_H -c ./Demo/r.cxx
Include/CXX_Objects.h: In method `int ::Py::String::capacity() const':
In file included from Include/CXX_Extensions.h:8,
                 from Demo/r.h:3,
                 from ./Demo/r.cxx:1:
Include/CXX_Objects.h:1237: Internal compiler error.
