I cant download the blockchain, getting 3kb/s and getting slower

Try
dpkg --get-selections | grep libdb
to determine your version of BerkeleyDB.
I bet it’s 5.1 or newer.

ninjaedit: with your last update to your post I think we’ve found the likely issue - libdb5.1

Have a look at https://docs.nubits.com/nu-raspberry-minting/ which contains a guide how to compile libdb4.8

[nuclits]

amnesia@amnesia:~$ dpkg --get-selections | grep libdb
libdb5.1:i386 install
libdb5.1++:i386 install
libdbus-1-3:i386 install
libdbus-glib-1-2:i386 install

[nuclits]

So what do i do, will this not work with nu or am i forced to wait on this to download?

[masterOfDisaster]

Have a look at https://docs.nubits.com/nu-raspberry-minting/ which contains a guide how to compile libdb4.8

Compile a new version of the Nu wallet using libdb4.8.
I’m not 100% sure, but quite confident that this will solve the problem.
Plus it will make the files created by your Nu wallet compatible with official releases (important for walletB.dat and walletS.dat).

[nuclits]

Is there anything from that large block of apt-get code i should remove? That nuclient was the first thing ive ever compiled and i dont know what any of that code means

[masterOfDisaster]

First
sudo apt-get remove libdb5.1++-dev
Or whatever is needed to remove libdb5.1.
Then follow the guide to compile libdb4.8.
Then compile Nu wallet using libdb4.8.

[nuclits]

I followed your guide all the way up to

make -f makefile.unix

and it gives me this error:

root@amnesia:/home/amnesia/Persistent/nubits/src# make -f makefile.unix
make: makefile.unix: No such file or directory
make: *** No rule to make target `makefile.unix’. Stop.

But i had to skip the nubits download section because i already downloaded it and did alot of editing to all the files to get it to work in the first place. I did try to make it with the makefile i previously had but it threw an error so i deleted it figuring it was based off the old dependecies. Then i tried using

qmake “RELEASE=1”

but it says command not found.

[masterOfDisaster]

That’s strange.
https://bitbucket.org/JordanLeePeershares/nubit/src/6fe88883f316b1ff3448d52438e9d122f808da51/src/?at=master clearly contains makefile.unix:
https://bitbucket.org/JordanLeePeershares/nubit/src/6fe88883f316b1ff3448d52438e9d122f808da51/src/makefile.unix?at=master

[nuclits]

i do have a makefile but its in /src/src, im trying to build from the /src directory and its looking for it in there i guess, thats how i had to do it before. Should i move it?

[masterOfDisaster]

That’s strange. The repo has no src/src directory…
I guess downloading a fresh version from https://bitbucket.org/JordanLeePeershares/nubit/get/6fe88883f316.zip doesn’t sound very well, because of the extensive editing you had to do.
Moving makefile.unix from src/src to src shouldn’t hurt. I hope that’s all then…

I wonder how you compiled the version you currently have.

[nuclits]

In the official 2.0.3 wallet there is a source folder which has nubit.tar.gz which extracts to the source files which also have another src folder in it.

I copied makefile.unix in the main directory, now it gives

root@amnesia:/home/amnesia/Persistent/nubits/src# make -f makefile.unix
make: *** No rule to make target obj/scanbalance.o', needed bynud’. Stop.

[nuclits]

Maybe if there was an equivalent of qmake that your listed dependencies would allow me to run it would resolve itself?

[masterOfDisaster]

Ok. If you use the source code that comes along with a compiled version of the wallet software, then you have to do the compiling in that folder.
Please move makrfile.unix to src/src, change into that directory and compile in there with the same command you compiled the wallet the first time.

Compiling libdb4.8 worked according to the guide?

[nuclits]

Ouch, ok that worked and it hijacked my computer and gave me this error:

error writing to /tmp/ccDo6Y3g.s: No space left on device
compilation terminated.

Yes the lib4.8 compile worked just fine, the only thing that didnt work was creating a swapfile which is probably why this didnt work. Tails is a live OS, it doesnt have a swapfile, everything is done in ram, it has persistence but no tmp-like swap files are written to it, this is done for security reasons and because its usually run on a flash drive and swap would destroy it.

Is there some way to get this to compile in ram?

[nuclits]

I looked into setting up a ramdisk but i dont think tails would allow that. There arent any options in make to change where the tmp files are stored else i could create a tmp swap in my persistent drive, and the mkswap command doesnt list any options to relocate the swap directory, at least when i try it i get “amensia/home is a directory” and it doesnt create anything, ‘Swapon’ doesnt show anything either and despite issuing those commands it still tries to create files in the locked /tmp directory.

So unless you know how to change the directory from /tmp to somewhere else during compiling short of downloading and installing an entirely new OS i dont see how to make this work, which is absurd as i just compiled it successfully without it trying to store files in locked directories.

Why again cant i use the command qmake with these dependecies?

[dysconnect]

Do you think an alternative tmpdir can be set via environment variables?

[masterOfDisaster]

Why again cant i use the command qmake with these dependecies?

I’ve never used qmake as I always only compiled nud (command line only daemon) on my RaspberrPi. That was possible with 512 MB RAM. With the RaspberryPi2 I’ve successfully compiled nud 2.0.3 using make with 1 GB RAM.
But I have no experience with qmake. Maybe that needs more RAM to build an executable.

Can you limit the number of threads when compiling with qmake (in case qmake uses more than one thread - I don’t know how to do that, though)?
Have you considered using make instead of qmake to compile nud instead of nu-qt?

I’m still not sure that it’s really related to the libdb version, although that is my best bet.
Wanna try compiling nud (make -f makefile.unix using the correct libdb version) just to find out whether the dat files I’ve uploaded work?

[nuclits]

The original libraries were:

sudo apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev libdb5.1+±dev libboost-all-dev libqrencode-dev libminiupnpc-dev

and your libraries are

sudo apt-get install checkinstall subversion git git-core build-essential libssl-dev libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libcurl4-openssl-dev libminiupnpc-dev

Looking closer i saw that qmake was an additional library so i retried it with that and it allowed me to generate my own build files, however this time it would not make, throwing some error about something missing, which i suppose is better than complaing about not having enough space and not giving me the option to give it that space.

I dont know what to do now, none of this stuff works. The code i have i know works but you say i need an older database so suddenly trying to use that older database breaks everything else.

edit: removed reundant code posted in other thread

[nuclits]

Maybe your code only works on the raspberry pi, since the original code worked just fine except for having the wrong db version i went ahead and tried it but with your db install code, however during it i found that the db did not install correctly. After using your first block of code for it:

cd ~/
wget http://download.oracle.com/berkeley-db/db-4.8.30.tar.gz
tar xvf db-4.8.30.tar.gz
cd ~/db-4.8.30/build_unix
…/dist/configure --enable-cxx
make

I did the next block

root@amnesia:~/db-4.8.30/build_unix# sudo make install

make: *** [install_lib] Error 1

edit: nevermind the error is true, all this crud ive been downloading has eaten up all my space, maybe this will work…

edit; nope. Tails system partition is only large enough to fit its own files. This berkekly package, because its not part of the apt-get repo it wants to install itself elsewhere where theres no room. So in short the old db that nubits client requires wont install on tails therefore the only way to proceed is to download and install linux and try it on there. Wonderful.

[masterOfDisaster]

I’m sorry for that.
