Hi All,
I've got a large C++ application that compiles/runs just fine on RH7.3 - I'm in
the process of porting it to RHEL3, and I am having some issues.
My program has some usage of iostreams / fstream / etc C++ constructs.
Some of the questions I have come across are:
- I noticed that there are 2 sets of C++ header files.
one is "compat-libstdc++-devel-7.3-2.96.123", and the
other is "libstdc++-devel-3.2.3-24"
Is there any rule of thumb as to which set of header files I should
use ?
- It seems that by default, libstdc++-devel-3.2.3-24 is being used.
As I have a lot of pre ISO C99 constructs, this set of header files
seems to be giving me fits. If I use -I /usr/lib/g++-3, most of my
compilation errors go away (but leave me w/ link errors). Question
is there a non-default c++ library that I need to specify ?
- What are the implications, limitations, issues, with linking together
object files created with -I /usr/lib/g++-3, and without (i.e. with
"standard" g++ header files. i.e. should this work ? Is this known to
not work ? etc.
any thoughts, or tips (or pointers) would be much appreciated.
thanks you, and best regards,
-Greg Hosler
