    Application don't start

    Hi all,

    I cannot start a program, or better to say, I am not sure if it started.

    I downloaded from http://lavapit.lavajumper.com/download the
    sexcoin program http://lavapit.lavajumper.com/dl/sex...4-64bit.tar.gz
    Version 64 bit which is for Ubuntu 13.04. (yeah, I want to mine some alternative Bitcoin )

    I have an Lubuntu 13.10,

    I started and get
    Code:
    istvan@mypc:~/Downloads/sexcoin$ sudo ./sexcoin-qt ./sexcoin-qt: error while loading shared libraries: libboost_system.so.1.49.0: cannot open shared object file: No such file or directory
    So I added this line to /etc/apt/sources.list :deb http://security.ubuntu.com/ubuntu quantal-security main and installed the libboost1.49-all-dev package

    Code:
    istvan@mypc:~$ sudo apt-get install libboost1.49-all-dev
    Now I start, but no response if it started..

    Code:
    istvan@mypc:~/Downloads/sexcoin$ sudo ./sexcoin-qt
    istvan@mypc:~/Downloads/sexcoin$


    - in which Ubuntu Logfile can I check when a program wanted to start ?
    - maybe with errors? which are not generated by the program itself but by Ubuntu?


    thx

    Thx for your answer.

    But this questions are Ubuntu only :

    - in which Ubuntu Logfile can I check when a program wanted to start ?

    - maybe with errors? which are not generated by the program itself but by Ubuntu itself?

    Re: Application don't start

    You can maybe use the ps command to see if a process named 'sexcoin' is running

    Code:
    ps -ef | grep sexcoin
    As to where any errors go that would be up to the writers of the application - likewise log files (since you ran it with 'sudo', there should be an entry in /var/log/auth.log but that just says that you issued the command - it doesn't tell you anything about what happened after)

    great, thx
    It also shows grep looking for "sexcoin"

    istvan@mypc:~$ ps -ef | grep sexcoin
    istvan 11080 5490 0 23:02 pts/3 00:00:00 grep --color=auto sexcoin

    Re: Application don't start

    There's a trick for that

    Code:
    ps -ef | grep [s]excoin
    (the regex doesn't match itself)
