My compilation CFU (Cfish unofficial) 311219:
https://app.box.com/s/ngfw48kywk46dmlbwb0wnw4xwpqamdaj

ok after some tests i have to report hagtorp about his compile 31/12/19 ARM8 64bit:

android 9: cpu mediatek g90t(new) 2xa76+6xa55 all at 2.0ghz, 6g ram 128gb internal mem.(redmi note 8 pro)

both static and dynamic builds work perfect! initial speed at 5230 kn/sec without heat throttling for 15 mins! no bugs no time loss.
the only issue comes from droidfish 1.77 who doesnt supports up to 512mb hash

Send email to Peter O., with request to add more mb hash support. I also changed my smartphone (finally, after 3 years ), to Xiaomi Mi A1 = (android 1), 4GB RAM, 64GB storage, 8x snapdragon 625 at 2 GhZ.. Cheap beast!

Droidfish supports hash of 1 and 2 or more gigabytes. You need to put a special file in the uci folder, it unlocks a large hash. I forgot only what it's called. Google will help.

....In the meantime, here is a development version that disables the hash size limitation:

Create an empty file in a text editor. Rename it to
.unsafehash and put in the uci folder in the droidfish directory. Restart the application: the hash is unlocked.

yes unlocks more hash gb but the engine doesnt use it .it stay at max 512mb even if have checked 2gb.
on my new phone the bigger hash option is there but when i set to 2gb or 4gb its filled 100% like the 512 mb in 30 sec

Everything works. Have you forgotten to put an end to the file name unsafehash? The name of the empty text file should look like this: .unsafehash

yes within the uci folder t.unsafehash

[hagtorp]

yes within the uci folder t.unsafehash

This should be the file. Everything works.

I hope the moderator will transfer all our correspondence to the Droidfish topic. And then we litter the cfish branch.

He is empty. The role is played by its name.
