Thanks Eric for the hint.
I read some time ago some stuffs about the CMAKE_SIZEOF_VOID_P variable but
unfortunately, in the present case,
the problem is a bit different. It can be for example that on a 64 bit
machine, I would like to use the 32 bit
ifort version because the only version of Winteracter library I have is the
32 bit one. That's why I came to the point
that the only way to proceed was through a cmake option. I could also try to
guess the kind of build I would like from
the path of my compiler but this approach seems quite restrictive and
especially hazardous ...
This shouldn't be true.
the value of CMAKE_SIZEOF_VOID_P should follow the capacity of the
**compiler** used and not the capacity of the host.
It works for cross-compiling as well.
e.g. when I cross compile to Win32 on my Linux 64 bits host
CMAKE_SIZEOF_VOID_P is equal to 4 i.e. 32 bits.
In your case you are on 64 bit Windows host but you compile
your program using a 32 bits compiler, this should work.
The easiest way to check what happen is to try to print the value
of CMAKE_SIZEOF_VOID_P in yor case.
Hi Eric,
just put your snippet in a macros and everything worked fine: I could
"guess" the architecture properly. That's for sure from far the best way
to get rid of my architecture "problem".
thanks a lot
Eric
