I have not tried it on my Apple devices. Works well on my Android devices, I cannot Chromecast it, but can display on my FirerTV devices, as well as no problems on my Windows PC's. I have tested my Linux Systems yet.

On a side note the Desktop app offers even more functions.

There is nothing to fix really.
You have a parameter in your make file for NUMA (y/n)
I changed it to no, did a build, and mailed him a new binary.
Hi Dann (and Ron...),

A little update on my Cfish compiles for old XP 64-bit computer.

Your latest compiles you sent me, Dann, still do not work with me (also not on my Win 7 old laptop).

But my problem is solved, because I received working (for me) Cfish compiles from 2 origins:
*From a guy named Zippy in the TCEC chat, although he thought they were x32 compiles, actually they were base x64 compiles. He said "I turned off the numa and native arch for 32-bit and 64-bit base", whatever that means... (maybe you know? :))
*And more importantly, because they will renew in the future (and were even a little faster), through Damir, compiles made by a user called RomeoA28 on http://mzchessforum.com/ , the mzchess forum.

So thanks again for helping.

WIth -march=native, the compiler uses the instruction sets supported by the processor of the system on which Cfish is compiled. If Dann's processor is more recent than yours, his compiles with -mnative may not work on your system.

To avoid compiling with -march=native, simply add "native=no" to the make command:

Code: Select all

C:\Cfish\src> make profile-build native=no
The Cfish Makefile defaults to 64-bit compiles.

NUMA compiles should no longer have problems on Win XP.
