Re: [Mingw-w64-public] how to invoke (install?) mingw64.

[patrick f. <pa...@we...>]

Thanx Tor - did as you instructed.

The hello.exe compiled with x86_64-pc-mingw32-gcc is about 10X the size 
of the one compiled with simply gcc which would seem to indicate that 
the former is a 64 bit image and the latter 32.

But how does one check an image to directly to see if it's compiled 32 
or 64 bits?  (I've googled this some already but haven't yet found a 
good answer).

Tried objdump -i on both images.  And they both reported exactly the 
same results.  With briefly, lots of references to i386 and no 
references to, say, i686.  But objdump is probably not the tool I want.

It's been many years since I more than dabbled in UNIX land.

thanx - pat
