p2pool for core 0.16 question

J1732

Okay, that resolved that error and now I get one about the neoscrypt dll, I’ve run the setup.py in the neoscrypt folder. What am I missing?

Error while requesting best block header:

You are missing he dll file containing the neoscrypt code.

Did you perform the extra steps as described in the Requirements section of the README.md file?

Especially

C:\Python27\python.exe setup.py build --compile=mingw32 install

That line creates the dll you are missing, but it does’t work, if you have not taken the other steps described in the README.md file.

J1732

Yes, I followed the steps in the readme. The neoscrypt installed into my site-packages folder. It’s still throwing that error. I’ve also added the site-packages folder into my path environment variable.

Wellenreiter

If you are on a windows server, it could be placed into the directory, where the windows dll are located. normally it should work, if the dll is in the same directory, where the p2pool binaries are, but honnestly I’ve no real clue, where windows searches for dll files.

J1732

I don’t have anything like a neoscrypt.dll file… I’ve got a neoscrypt.pyd and a neoscrypt.egg could one of these work?

IF so, where would the p2pool code be looking for the dlls?

Wellenreiter

When you did the

C:\Python27\python.exe setup.py build --compile=mingw32 install

did you get any output? it should compile the neoscrypt module, so there should be some output of your c-compiler on the console/cmd window.

Can you paste that output?

Normally the command also should create a directory ‘build’ under the neoscrypt directory, which temporary holds the files.

if you don’t have that directory try

C:\Python27\python.exe setup.py build --compile=mingw32

and check for the directory and it’s content.

J1732

When I run the setup.py for neoscrypt this is the output in the console;

C:\Python27\Lib\site-packages\p2pool-neoscrypt-master\neoscrypt>python C:\Python27\Lib\site-packages\p2pool-neoscrypt-master\neoscrypt\setup.py build --compile=mingw32 install
running build
running build_ext
running install
running install_lib
running install_egg_info
Removing C:\Python27\Lib\site-packages\neoscrypt-1.0-py2.7.egg-info
Writing C:\Python27\Lib\site-packages\neoscrypt-1.0-py2.7.egg-info

C:\Python27\Lib\site-packages\p2pool-neoscrypt-master\neoscrypt>pause
Press any key to continue . . .

Which appears like it works correctly as the build directory is created.

running install_lib
…
Writing C:\Python27\Lib\site-packages\neoscrypt-1.0-py2.7.egg-info

I think, these are the important steps.
install_lib installs the library
Writing C:\Python27\Lib\site-packages\neoscrypt-1.0-py2.7.egg-info writes the information about the library like author, email address, license and platform.

I’m at the end of my knowledge. :(

The only thing I can think of is, that the file extension of the created file is not dll.

can you do anther setup.py, but without the final ‘install’ parameter?

Then you can check the content of the build directory and see what the exact file name(s) of the creates file(s) is.

I’m working on linux and have no experience with p2pool on windows.
I found some hints with google ‘setup p2pool on windows’, but i’m not sure if that will help you, sorry

J1732

Running just the build creates the neoscrypt.pyd file. It seems like the issue is that the python scripts run when starting the pool just don’t know where to find it.

It’s odd because I’ve run this setup guide on another windows machine and not had a single issue.

Wellenreiter

may be you can google, where python looks for the pyd files on windows?

J1732

yeah, I tried that with not much luck… the only thing I could find was a path issue, and I’ve added every directory I could think of to the path just to see if it helped. It didn’t.

I hope you aded the path, where the pyd file was installed. ;)

Also, did I get it right, that you got it working on another pc with the same OS?

Then as a last try you could copy the whole p2pool directory form that pc to the one with problems and see if it works, but I’m guessing now.

I have no idea anymore how to isolate and fix the problem :(

J1732

ha! Yeah, I added the directory for the .pyd to the path variable :D

I tried copying over the whole folder and it was no good. I’m going to try a new install on a completely different machine and see what happens… this whole thing is just weird.

I more than agree…

Wellenreiter

@J1732

any news here? did you get it working?

J1732

Almost. I created a linux box and got everything to run and compile right. The only issue now is when I try and use an newly generated receipt address from my wallet it won’t work. Runs fine if I use the address you show in the example at the beginning.

Any thoughts?

Wellenreiter

Feathercoin v0.16 generates bech32 adresses, which are not recognized by the current p2pool versions.

So i think feathercoin core 0.16 and onwards will default to segwit / bech32 addresses.

To generate a legacy address that’s you can use the feathecoin-cli

the command would be something like

feathercoin-cli getnewaddress "AddressLabel" "address_type"

so for you, you could do something like

feathercoin-cli getnewaddress "PoolWallet" "legacy"
