    C compiler cannot create executables

    I am trying to install clamav. When I ran Adept to install clamav I received an error message saying something like "...failed because of dependencies..." or something like that. I could not find a definitive log file for an explanaction.

    Since I am running Kubuntu Feisty Fawn I decided to install Klamav and see if that was part of my problem. I did install it, but it said that Klamav was out of date and that I should upgrade, which meant downloading and compiling the source. I procdeded to do that but I received the following error message regarding the compiler--

    ***** Klamav
    ***** Running configure (./configure)...

    * See `config.log' for more details.
    ***** Return value 77

    I looked in config.log and here is a portion of that file--
    .
    .

    .
    .
    .
    And it apparently points back to gcc. How can a compiler NOT be able to create an executable file??

    Any help will be appreciated.

    Re: C compiler cannot create executables

    Can you please check if you have the package build-essential installed? Sometimes this error message appears when you have missing development packages.

      Re: C compiler cannot create executables

      You are correct, Jucato--I had build-essential installed under Dapper Drake, but when I made a new installation of Feisty Fawn I neglected to install it. I also had to install several other applications as well.

      I have successfully compiled, configured, and installed clamav, but I am unable to compile the Klamav front-end. Here are some of the lines from config.log--

      and several others.

      Somewhere it mentioned that the library qt-mt was not found, and I have not found it in the distribution using Adept.

      I presume that there is a way to run clamav without using Klamav. I'll have to read up on the clamav documentation to discover how.

      Thanks for your help.

        Re: C compiler cannot create executables

        Have you installed kde development libraries (needed to compile kde programs)?
        Try installing kdelibs4-dev package and it's dependencies.

        Of course both programs should be installable through the repositories, if you could provide the exact dependency errors reported when trying to install via the repos it might help troubleshoot the problem. (If adept doesn't show the exact errors, you can use apt-get)

          Re: C compiler cannot create executables

          Thanks, kubicle. That did it! I have now compiled and installed Klamav and it's working fine.

          I'm a former main-frame programmer, but I'm just learning about compiling and linking on a Linux box. I didn't even think about needing KDE libraries and files in order to compile Klamav, but it makes sense.

          I guess the way to learn is to try...and fail...and then ask someone for help on the Kubuntu forum! That's worked for me so far.

          Thanks again.

            Re: C compiler cannot create executables

            What those -dev or -devel packages install the headers of those libraries that you need in order to compile something that uses those libraries. Normally, binary distros (those that ship software as binary packages) do not install the headers by default, the reasoning being that you only need these to compile software, not run them. So in most cases, you have to install the package(s) that installs these header files.

            (It may also install libs that you need to link to during compile time)
