I have some code, which happily runs on Ubuntu. Now, I have to port
this code to OS X. However, on compiling I get (hundreds of) errors
like:

/usr/include/c++/4.0.0/bits/localefwd.h:124: error: 'mbstate_t' was
not declared in this scope

Seems like 'mbstate_t' is undeclared... Are you sure your compiler
and library were correctly installed?

/usr/include/c++/4.0.0/bits/localefwd.h:124: error: template argument

/usr/include/c++/4.0.0/bits/localefwd.h:126: error: 'mbstate_t' was

/usr/include/c++/4.0.0/bits/localefwd.h:132: error: expected `>'
before 'istreambuf_iterator'
/usr/include/c++/4.0.0/bits/localefwd.h:132: error: expected
unqualified-id before '>' token
.....

I am using a (qmake generated) Makefile, with the following call for
each cpp-file:

c++ -c -pipe -Wno-deprecated -I/sw/include -g3 -D_REENTRANT -
D_GNU_SOURCE -fPIC -DNDEBUG -g -g -Wall -W -DQT_GUI_LIB -DQT_CORE_LIB

-F/usr/ local/Trolltech/Qt-4.3.2/lib -o objects/iGRLVQ_Demo.o
iGRLVQ_Demo.cpp

Any suggestions? This is (unfortunately) somewhat urgent because I
have to give a talk and a deadline on this on Thursday and would like
to use os x for it. It should be pretty easy (I hope)..

Suggestion: Switch to Ubuntu for your talk. Without seeing the code
all I can recommend is to ask in OS X newsgroup.
