SV: [Dev-C++] Cannot compile using Dev-C++ 5.0 beta 7 (4.9.7.0) ( 10 MB) with Min

[Lars-Bo J. <la...@fo...>]

Well that really does not help on the stated problem. I have the exact =
same
problem, I have developed a program with the gcc 2.95.3 version of =
Dev-Cpp
then I changed my dev-Cpp to the version with gcc 3.2 because I wanted =
to
experiment with wxWindows 2.4. No problem at all, I went thru some =
tutorial
on wxWindows and everything works fine.<?xml:namespace prefix =3D o ns =
=3D
"urn:schemas-microsoft-com:office:office" />

=20

But today I needed to make a change to my original project developed =
with
gcc 2.95.3 and I get the same errors and a lot of them (and all my =
includes
are correct). But due to this thread I realize that none of my =
wxWindows
test/tutorial programs uses iostream hence the problem with gcc 3.2 =
first
appeared today.

=20

Of course I realize that the problem could lay somewhere else then in =
the
dev-cpp distribution but I have tried to install it on an NT4 and an xp
machine and the same problem arise. So I will solve this the same way =
as
Martin Clausen(copying from one ....\bits directory to the other) =
anyway I
glad I am not the only one who experienced this problem hope someone =
not as
newbies as I will have the insight to understand what's going on.

iostream.h is not proper C++. After the official ANSI/ISO C++ standard
ratification, standard library header files have no .h extension except =
of
the C subset. Everything is defined in namespace std. Example:
=20
#include <iostream>
=20
int main()
{
  std::cout<<"Hello new world!\n";
=20
  return 0;
}
=20
The C subset header files also exist in the form <cxxxx>, e.g. =
<cstdlib> and
everything in them is also defined in namespace std. Example:
=20
#include <iostream>
#include <cstdlib>
=20
int main()
{
  using namespace std;
=20
  cout<<"Hello new world!\n";
 =20
  system("pause");
=20
  return 0;
}
=20
=20
A slow thorough read of an up to date C++ book will have much to offer.

Hi again,

Thanks for input Robson. The only iostream.h file in all directories =
under=20
Dev-Cpp is in C:\Dev-Cpp\include\c++\backward.

I swear I haven't touched a single thing :-) - just installed and run =
out of

the box. How do I get the compiler to find the iostream.h file ? and =
all the

other legacy files ? or is there somthing more fundametally wrong with =
my=20
setup ? do you have iostream.h located somewhere else ?

Just so I don't waste anybodys time, the problem only arises when I =
used the

latest version with Mingw/GCC 3.2 - with Mingw/GCC 2.95.3 everything =
works=20
fine.

Martin

[Dev-C++] unicode

[Torsten C. <tc...@df...>]

I just switched my application to unicode by specifying the
"-D UNICODE" and "-D _UNICODE" compiler options.

But the STL string class refused to accept that. Though
it uses the "charT" type.

Any pointers how to switch it to unicode?

=3D=3D> Try using wchar_t *built in* type which is also portable. And for=

For example:=0D

For wide character sets, wchar_t is your type and where UNICODE is suppor=

 it usually is UNICODE.=0D
=0D
=0D
Unfortunately (& strangely) i have the impression that MINGW does not
provide wcout, so in this case you will have to use the C-subset wprintf(=

in the style:=0D
=0D
wprintf(L"%s\n", s);=0D
=0D

Try being as much portable as possible. In this way you will have fewer
incompatibilities with other compilers or even next releases of your
compiler.=0D

 and since it is fixed by using the files of a MINGW bits folder, then it=
 is
a bug of Dev-C++ for not including that path? Whether it is of Dev-C++ or
