I am building Monero from source on Ubunto 16.04 LTS.

Eventually, it gets to 98% but then gives an error. However, I am still able to run monerod. Can anyone elaborate as to what has happened?

(I have tried building on Ubunto 14.04 and 17.04 with failures at around 42% many times. This is the further I have got)

However, I can run monerod:

You can set the level of process detailization through "set_log s>" command, where is between 0 (no details) and 4 (very verbose), or custom category
based levels (eg, *:WARNING).

Use the "help" command to see the list of available commands. Use "help " to see a command's documentation.

  • Could you please provide the environment you are trying to compile? – deepcell Dec 14 '18 at 6:36

The simple answer is that make will build a whole bunch of stuff (i.e., monerod, monero-wallet-cli, monero-wallet-gui, monero-blockchain-import, etc., along with all the files it compiles as precursors to those binaries). At the end of the build process, it builds tests. Your error comes at the stage of the build process where all the main binaries have already successfully been compiled, and it's the building of the tests that has failed.

Your error reflects that you have libgtest on your system, but it wasn't compiled with the -fPIC flag. You can either recompile with -fPIC, or see this SE question/answer for other possible solutions (e.g., uninstall libgtest).
