Monero Support

I also tried

sudo apt-get install gcc

 

sudo apt-get install g++

  
and was told that they were already installed and up to date.

Hmm, it says the error is opening the file "for writing"

That sounds like a permission problem or less likely disk full.

Do you try to do some of this stuff as root or another user?

Try "rm -rf build" to delete the build directory and start over (assuming you don't have any wallet files in there)

[binaryFate]

Try:

chown -R <your_user_name>:<your_user_name> ~/Monero/bitmonero/

Close your console if you never did after latest installations (env variables messed up?), open new one. Then:

make clean
make

Yeah, I just did this.  I sudo-deleted the build folder, and tried to reconstruct it (same error).  
  
I then backed out of the entire directory, deleted that, and redownloaded it with

sudo git clone https://github.com/monero-project/bitmonero.git

 
  
and tried re-making it, and still the same error.  
  
I only have one user account on this install, which is me with an administrator type account.  I guess the only piece of information at all relevant to my install is that I chose the encryption option and encrypted my operating system with a tough password.  
  
Sorry it's being so frustrating.

This git clone step (and then make) does NOT want sudo, only apt-get commands do.

Close your console if you never did after latest installations (env variables messed up?), open new one. Then:

make clean
make

I did everything you said, including closing out the terminal and reopening.  After using the "make clean" command it warned me it would delete my wallet, which I agreed to.  Then I used the "sudo make" and regular "make" command again and got this error both times:

Ok, I'll try deleting everything and redownloading it with a regular command and see if that helps...

[smooth]

you are getting close, I think missing openssl libraries

sudo apt-get install libssl-dev

Do not do 'sudo make' , just 'make' (nor as binaryFate pointed out, should you use sudo with anything else involved with building, cloning, etc.) -- that's probably what caused the problem before. sudo should be used only for system admin tasks, not building.

make: *** [release-all] Error 1

Given the libunbound error, berkeley db error, openssl, etc, I don't think the initial dependencies are being installed for whatever reason. I had this problem before the guide for mint was written, and just one by one installed each of them until it worked.

I'm pretty sure the install apt-get command given is correct though. I can check later to see if anything is missing.

I'm pretty sure the install apt-get command given is correct though. I can check later to see if anything is missing.

Ok, so I went word by word through this command and tried to "sudo apt-get install" them all:
 

sudo apt-get install git gcc-4.9 cmake libunbound2 libevent-2.0-5 libgtest-dev libboost1.55-dev libboost-system1.55-dev libboost-filesystem1.55-dev libboost-thread1.55-dev libboost-date_time1.55-dev libboost-chrono1.55-dev libboost-regex1.55-dev libboost-serialization1.55-dev libboost-program_options1.55-dev libunbound-dev build-essential libssl-dev libdb++-dev

 
 
It's important to note that even though I had done this mass command before, there were several (at least 5) of these libraries that did not install with the mass command.  When I tried to install them, they went through as if I had never tried before.  Something is wrong with the mass command that is not installing all the required libraries!
 
One of them could not be found, even with an individual command. 
 

sudo apt-get install libboost-program_options1.55-dev

does nothing. 
 

 
 
After manually installing all the libraries, it's compiling! 
 
Hopefully it completely compiles into a usable state, and I can play with it.  Thank you so much for all the technical support and patience!  It's nice to troubleshoot these issues so we can help future newbies understanding exactly what they have to do.... type in every one of those commands, step-by-step.

yeop, and now you can help noobs! I tried to edit my compile overview accordingly, I should probably add the "add them line by line"

I found a couple of typos in the command to install dependencies for Monero build on Linux Mint 17.2. There were a couple of _ where there should have been -

For anyone else building on Mint 17.2:

Code:

sudo apt-get update

Code:

sudo apt-get install -y git gcc-4.9 cmake libunbound2 libevent-2.0-5 libgtest-dev libboost1.55-dev libboost-system1.55-dev libboost-filesystem1.55-dev libboost-thread1.55-dev libboost-date-time1.55-dev libboost-chrono1.55-dev libboost-regex1.55-dev libboost-serialization1.55-dev libboost-program-options1.55-dev libunbound-dev build-essential libssl-dev libdb++-dev libdb-dev

Code:

git clone https://github.com/monero-project/bitmonero.git
cd bitmonero
make

Hey so here's a dumb questions from someone with general knowledge of linux (ubuntu) but certainly has gaping holes in their understanding. I can compile monero from source  and scrounge up missing dependencies, blah blah blah, but how to switch from compiling from master branch of github to the development branch. Something simple like...

Code:

git clone https://github.com/monero-project/tree/development/bitmonero.git

or some such thing? I know it gets asked all the time but can't find. Want to play with lmdb

IIRC, the LMDB is already merged to the master branch. Just compile from the latest commit -> https://github.com/monero-project/bitmonero/commits/master

Unfortunately I am not really tech-savvy, so can't really help you with your question. Also, if I am wrong in my above sentence, someone please correct me!

If so... then would bitmonerod compiled from master branch build and use the block database using lmdb if you sync from scratch, but would not if you bootstrapped for instance?

Thanks for help

I believe by default (with no switches) it'll select LMDB and ignore any current standard chain you have, meaning it'll start syncing from 0. I'm not at acomputer to check for sure though. Note: on a 50 mbps fiber connection today I synced from 0 in 47 minutes.

You'll also want to make sure you freshly compiled from today, as there's a very important fix to the daemon just merged.

As others have answered, you don't need to switch branches to compile the LMDB version. Also, so many improvements have been made that its not really a timesaver to bootstrap the blockchain with a download anymore, you can sync from zero in about 1 day max if you have a slow connection, faster if you don't.

To answer your question about how to switch branches, use this after you clone a repository:

Code:

git checkout <branch name>

[g4q34g4qg47ww]

Radical. It's synching like a mad man and using basically no memory. Here I was thinking it was brooding in some murky testing corner. Thanks for the help everyone. Luigi , i grabbed a fresh one. Saddam, I need to learn more git cli navigation .. which sounds strange...

[afbitcoins]

I really want to like monero but the barriers to entry seem huge almost to the point of me giving up.

First off there is no 32 bit linux version. Despite this being a major annoyance to me I've changed my OS to a 64 bit version. This hasn't got me much further though. I'm not a linux noob btw.

I'm trying to run the latest stable version which is 0.8.8.6 After several annoyances with dependencies with libboost i finally can start up bitmonerod

I am still unable to sync the blockchain though.

Firstly I've tried downloading the latest copy (currently about 4.2 G) but download keeps failing and I can't resume and have to start again. Can there not be a torrent or something ?

So instead I try syncing from scratch. Initially it said I am about 481 days behind. However I've tested exiting the daemon and found that regularly doesn't shutdown cleanly which results in all the syncing of that session lost.

I see message

'Stop signal sent'

but then the computer hangs and the changes to the blockchain do not appear to be saved. I've reluctant to leave it running for 2 days to sync the blockchain only to find nothing gets saved at the end!

This doesn't even yet get into the simple wallet. How does it work? Wheres the instructions ?

I am not going to buy monero until I can hold off exchange.

If you want to know why monero price is stagnant, I think these are the reasons .
