There appears to be a problem with the non-installation of the
include files in the port.
Specifically, the include file "typeinfo" is not installed,
and it seems that there is not a sperate installation of a
"include/g++28/" directory, in general, and that an installed
"/usr/local/bin/g++28" therefore uses the previous "g++"
includes, which are for g++ 2.7.2.
This results in failures when attempting to use runtime type
information (RTTI). This is just the most obvious failure;
I am sure there are other compiler/include file mismatches...
Specifically, things like:
#include <typeinfo>
// pseudocode... too lazy, too obvious, takes too much space...
class foo {
...
};
class fee : public foo {
...
};
class fum : public foo {
...
};
// real code follows...
void
gettype( char *s, foo *obj)
{
if( typeid(foo) == typeid(*obj))
printf( "object named '%s' is of type foo\n", s);
else if( typeid(fee) == typeid(*obj))
printf( "object named '%s' is of type fee\n", s);
else
printf( "object named '%s' is an unknown subclass (%s), s,
typeid(*obj).name);
}
main()
{
foo *foo1;
fee *foo2;
fum *foo3;
foo1 = new foo;
foo2 = new fee;
foo3 = new fum;
gettype( "foo1", foo1);
gettype( "foo2", foo2);
gettype( "foo3", foo3);
}
Fail because the wrong <typeinfo> gets included.
This works correctly when you use the gnu configure based install.
I recommend making the compiler reference an ./include/g++28/
directory, and installing the correct include hierarchy there,
wherever that is (probably /usr/local/) to resolve the problem.
Sorry, I don't have patches; I don't quite follow the way the
ports are supposed to actually work, and am too buried to be
able to pitch in on fixing the port. 8-(.
