Rev. 7830 build issues

[ironhead]

I've updated to rev. 7830 and I'm having issues compiling using 32-bit mingw:

I'm guessing a type issue with the 64-bit modifications?

I got this also (win7 64-bit, but 32-bit compiler).
It comes from these changes:
http://svn.berlios.de/wsvn/codeblocks/trunk/src/plugins/debuggergdb/debugger_defs.h?op=diff&rev=7828

wxString::ToULong, needs an unsigned long * as first parameter, but gets a size_t *.
size_t is defined as unsigned int on 32-bit and can not guarantee to hold the conversion to unsigned long (obviously).

What compiler are you using?

I did the same yesterday (without the win64 macro) and it works here (TDM MinGW 4.4 32-bit).

Win32 build of Code::Blocks main project compiled with the above patch did not try running or compiling contrib projects.

why not always have both variables being of type unsigned long ?

[MortenMacFly]

Because on 32 bit its unsigned long int, on 64 bit its unsigned long long (size_t).

[MortenMacFly]

did not try running or compiling contrib projects.

Contrib plugins are not yet supported for 64 bit builds, 32 bit builds should not be affected.

[ironhead]

Because on 32 bit its unsigned long int, on 64 bit its unsigned long long (size_t).

Why not just use size_t and leave it to the compiler to sort out?  32-bit MinGW will define size_t appropriately, as will 64-bit mingw-w64.

[killerbot]

Because on 32 bit its unsigned long int, on 64 bit its unsigned long long (size_t).

Yes, so, if I look at the ifdef posted above (note WIN64 --> what happens on linux 64 bit ??) :
if WIN64 bit --> size_t ==> 64 bits  BUT unsigned long is also 64 bit on 64 bits machines
else (considering this means 32 bit !!!! ??)
unsigned long ==> 32 bits, but size_t is also 32 bits here

Meaning that either unsigned long can be used in both cases, or for that matter size_t can be used for both.

When using unsigned long for printf '%lu' can be used,
and for size_t "%zu"

[MortenMacFly]

and for size_t "%zu"

Uaaah - careful here, remember that this caused a silent crash? I would prefer a solution that uses a well established standard... hence I don't know any. :-(

Win 32 -
size_t => unsigned long int

Win 64 -
size_t => unsigned long long int

Linux 32 & 64 bit
size_t => unsigned long int

So if you use size_t it'll work on all platform. However printf format identifier will be different only under Win 64. You have to use %I64u printf format string to print unsigned 64 bit integer.

[Jenna]

As far as I know size_t is usually the same as __SIZE_TYPE__

Win 32 -
size_t => unsigned long int

__SIZE_TYPE__ => unsigned int

Win 64 -
size_t => unsigned long long int

not tested

Linux 32 & 64 bit
size_t => unsigned long int

Linux 32:
__SIZE_TYPE__ => unsigned int

Linux 64:
__SIZE_TYPE__ => long unsigned int
