Native Windows 64-bit build?

ROOT
21

No problem, don’t worry, but do you (or any of your users) really need 64-bit build?

22

I am very interested in a native 64-bit build for Windows 7.

It is a requirement for us, because some of the hardware we use for data acquisition is only supported on 64-bit Windows. Our application does large scale real time cellular data analysis.

Hi buddy,

And what prevent you to run 32-bit binary of ROOT? (it runs perfectly well on 64-bit Windows 7…)

Cheers, Bertrand.

Bertrand,

What prevents that is a funny little driver, than when run in 64-bit mode, can only talk to a 64-bit app.

It is similar in my case. I write a Java software that uses some bits and pieces of ROOT through JNI. I need plenty of memory available and 32-bit ROOT forces me to use 32-bit JVM => not more than ~1.2GB of memory available on windows for my code.

Old thread but the subject is still topical: while ROOT 6 doesn’t yet support Windows at all, if/when it does, is there going to be 64-bit Windows build?

Hi,

Once ROOT 6 works on Windows, Win64 should be supported (once all pointers to long conversions are changed…)

Cheers, Bertrand.
