Can someone kindly advise me what the issue is with Ubuntu 14 LTS installation? I'm a Ubuntu newbie but have followed the instructions and running sudo bash ./install-sx.sh file from / (root) always gives this install error:

sim@ubuntu:/$ sx
The program 'sx' is currently not installed. You can install it by typing:
sudo apt-get install lrzsz

Everything is fine up until this point.

Any help would be greatly appreciated; have literally spent 2 days trying to work this out with LTS 12 now LTS 14 (ie I'm not here as first resort, I've RTFM!)

TL;DR:

Ubuntu 14 LTS, how to fix this error?

Code:

utility/ec_keys.cpp: In function 'bool libbitcoin::ec_multiply(libbitcoin::ec_secret&, const ec_secret&)':
utility/ec_keys.cpp:133:64: error: 'secp256k1_ecdsa_privkey_tweak_mul' was not declared in this scope

I had the same issue and fixed it.

Make sure you have:
1- secp256k1 installed
2- libbitcoin installed

To install secp256k1:

Code:

$ git clone https://github.com/bitcoin/secp256k1
$ cd secp256k1
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

To install libbitcoin:

Code:

$ git clone https://github.com/libbitcoin/libbitcoin
$ cd libbitcoin
$ autoreconf -i
$ ./configure --enable-leveldb
$ make
$ sudo make install
$ sudo ldconfig

You will likely need to do the following as well:

Code:

$ sudo apt-get install build-essential autoconf automake libtool libboost-all-dev pkg-config libcurl4-openssl-dev libleveldb-dev libssl-dev

I still get HeadsOrTails's error of "utility/ec_keys.cpp:134:1: warning: control reaches end of non-void function" whenever I try to make libbitcoin after the configure step. Any advice or things to try?

That's just a warning, you should be able to build it despite that message. If it isn't building successfully, it must be another error.

To get rid of the warning, find the function and have it return something at the end.
