Re: error building Fox-1.7.90 on windows

 That fixed it. Thanks.

2 questions:

1) I get a bunch of conversion warnings...are you interested in
seeing these or do you already know about them?
2) The library is called "foxlib.lib" the current one I'm using
is called "FOX-1.7.lib" Did you or I change the name?


1 observation, it's probably a c++ question:

I have a very large data structure. When the program is running
it uses about 700 MB of RAM. It runs without problems. I also
have a mode where it makes some copies of this large data
structure and runs a bunch of checks on it. When it is doing this
is used about 2.4 GB. I recently noticed that the data structure
is now being corrupted when I run these checks. After much
debugging I decided to change my app from 32-bit to 64-bit. It
now runs fine. 


Thanks,

js

Yes, this is a quaint error, and I have seen it, too.

The fix:

   start RegEdit.exe

   Goto sub-hive:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

   Change key LongPathsEnabled and set it to type DWORD value 1

You may have to reboot, I'm not sure.  Its probably best if you
reboot after this.

Symptom: fire up VStudio 2019, load FOX project, and try build
it.
This errors as VStudio needs paths longer than 260 characters due
to deep directory structure.

This is insane, and may be new to Windows 11.  I'm pretty sure
I've never seen it om Windows 10.  But we all know how royally
F***ed Windows 11 is..


Anyway, the fix is easy.
