I still would stick to the fact that I am able to use
fftw comfortably with  Windows binaries compiled with
gcc under MinGW which I downloaded from :
ftp://ftp.fftw.org/pub/fftw/fftw3win32mingw.zip

I just link to the fftw3.lib file! There has been a
debate on wether a *.lib file can be linked. But
around 2 weeks back there was response, I do not
remember from whom, which said the *.lib files created
using the C language can be linked even under the gcc
system. I guess this is how I am able to get my work
done!

Siva Chandra.

I left out % in my answer.

This is the same as writing:

firstnamelength = firstnamelength + 10;

You can do the same thing with -, *, and /.

Do you understand ++ and -- and the ?: syntax?

It means
firstnamelength = firstnamelength + 10;
You can use it with +,-,*,/ and %. See one more example
below:
"firstnamelength /= 10;" ==> "firstnamelength = firstnamelength / 10;"

Hello,=20

As we can see the compiler complains about the class
definition in the *.cpp file.

>  \myFolder\myClass.cpp In constructor
> `myClass<Type>::myClass(const Type&)':
>=20
> 7 \myFolder\myClass.cpp syntax error before `;'

> Error 1=20

And, the complaint is about the way you have created a
new myClass object. Firtsly, you have declared a
protected member object of type Type in the class
declaration and not a pointer to an object of type
Type. So I guess the declaration code should be
changed to:

Type* count; // Declare count as a pointer.

Next, even after making such a correction, the way you
should go about initialising this object is:

count =3D new Type(item);

and not as:

count =3D new Type item;

Even here, the class of type Type should have a
logically correct copy constructor.

Hope this helps,

TCHAR is either wchar_t or char depending on if you compile for unicode
support or not.

Same with the defined string functions. They translate to a wstrxxx or
strxxx function.

You should have a tchar.h file in your mingw include directory.

Hi all.

I was working on gcc environment. For making some plugins and tools in
my office (WIN2K os), I tried to use Dev-C++ to write them. But, too
many things beat me.

First is the string, the essential stuff but rather confusable. MS
define too many typedef, such as TCHAR or LPCSTR, etc. I don't know
which types and functions I can use in GCC, wchar_t or char? wstrxxx or
strxxx?

I need a manual about porting MS to gcc, any url or hints?
