Hi,

I am planning to migrate to Windows 7-64 bits. Is there any incompatibility between Windows 7 and U++? Is there any problem with Microsoft C++ compiler for 64 bits? Are there useful tips to be considered?

Thank you,

Javier

Using a 32 bit U++ I can say that I did not find any incompatibly and everything runs smoothly. Can't say anything about 64 bit except that it compiles.

I'm not sure if it is a fault of visual studio 2010 sp1 but I debugger is not working in windows 7 64b. Everything else works fine.

Which debugger and for what code?

I am Win7 user, well, most of time, and theide debugger debugs 32-bit apps just fine.

64-bit debugging was never finished AFAIK. There are some patches applied for that, but I have never seen it working...

Mirek,

What you are saying is that it is not possible to debug a 64 bit compiled application with U++, is it not?

For example, let us say that you are planning to compile a program with U++, using the Microsoft 64 bit C++ compiler, is it possible to do it completely in U++, including its debugging?

Since you are working with a 64 bit environment (Win 7-64 bits), are not you making the most of it? I mean a 64 bit application, running in a 64 bit environment, has to be better compared with its equivalent developed in a 32 bit system.

Yes, everything works except integrated debugger.

Only marginally. And as the most executables I produce for my living have to work on 32-bit windows, it really does not matter much.

I guess for most win32 programmers this is the same. Perhaps this is why nobody bothered to fix that debugger yet Smile (Even if that should be relatively easy).

I meant TheIde's debugger in Win7 64. Two weeks ago I had to work only on my laptop (where Win7 64 is installed) and lack of debugger was really annoying Smile. It would be great Mirek if you could take a look at it (of course there is no rush).

I repeat that I am running Win7 64 and debugger works just fine, for 32-bit apps.

So, are you referring to 64-bits apps (where it is known it does not work), or something bad is with 32-bit apps debugging?

Mirek,
I think he refers to the 64 bit case; it would be great if someone fixes the debugger for this case.

Anyway, I think the migration to a full 64 bit environment is unstoppable (the same as when we passed from 16 bits to 32 bits!), so it is better to joint it!. Smile

I'm sorry I thought it was clear Smile. I was trying to debug 64b application. But if debugging 32-bit apps in 64bit environment works then no problem (why I didn't try it - I really don't know Smile ).

Well, actually, as matter of fact, 16->32 bits was a big change (a big simplification), 32->64 is negligible change.

You can debug your U++ code compiled 32bit and then compile 64 and there is 99% chance it will work. I am doing that on regular basis in my work - we share code that I get developed in 32-bit windows and later it runs (without much further testing) on 64bit linux.
