In re the changes to CXX in release 8, I had noticed that in 1.5.2 there
were some new members in the type tables. I didn't track how far back that
change went -- 1.5, 1.5.1, ?. But if it doesn't compile you can just kill
the new members as I'm not using them for anything yet as I haven't had time
to figure them out.

As to the comment someone posted about the release 8 Windows installer not
wanting to work with 1.5.1, this is because it is supposed to set a registry
key based on the Python version. Maybe I'm not doing something right. If you
don't have the key that matches your Python then the python path is screwed
up.

I'm in the process of moving my office so please forgive the slow responses.

Subject: [C++-SIG] CXX (Release 8) and EGCS 1.1.1
Message-ID: <13980.59696.202508.732803@aragorn.harvard.edu>

Has anyone successfully used CXX (Release 8) with EGCS 1.1.1? When I
try to compile any of the examples that are distributed with CXX I get 
the following messages:

gcc -I/home/barnard/lib/include -I/usr/include/python1.5  arraytest.cxx
/home/barnard/lib/include/CXX_Objects.h: In method `class ::Py::seqref<T> ::Py::SeqBase<T>::front()':
In file included from /home/barnard/lib/include/CXX_Array.h:3,
                 from arraytest.cxx:5:
/home/barnard/lib/include/CXX_Objects.h:923: use of class template `template <class T> ::Py::seqref<T>' as expression
/home/barnard/lib/include/CXX_Objects.h: In method `class ::Py::seqref<T> ::Py::SeqBase<T>::back()':
/home/barnard/lib/include/CXX_Objects.h:931: use of class template `template <class T> ::Py::seqref<T>' as expression
/home/barnard/lib/include/CXX_Objects.h: In method `int ::Py::String::capacity() const':
/home/barnard/lib/include/CXX_Objects.h:1229: confused by earlier errors, bailing out
make: *** [all] Error 1             

I'm not sure if the problem is with the template mechanism or the
namespace mechanism (everything that's supposed to be under the std
namespace is in the global namespace for the libstdc++ distributed
with EGCS 1.1.1). Turning off namespace support in CXX doesn't help. 

I'm running Red Hat 5.2 (2.0.36) on a Pentium II.

Someone told me they had succeeded with another alteration to the config
file, but that the resulting compile times were through the roof.

This would indicate ECGS is not good at templates. If so, this is a
not-unheard-of state for a C++ compiler. I plan to try ECGS myself at some
point.

I regret that I lost this message in the process of moving recently. If the
person who sent it to me would comment about the change necessary I would
appreciate it.
