    With autotools I get this:

    [email protected]:~/Downloads/akonadi-googledata-1.2.0/build/build$ autoreconf -i -f
    Can't exec "libtoolize": No such file or directory at /usr/bin/autoreconf line 196.
    Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 196.
    autoreconf: `' or `' is required

    what does `which g++`say? Obviously there is no working c++ compiler on the system.

    It doesn't say anything. I have GCC installed if that helps.

  • Install build-essential Install build-essential if you haven't done so already. You can install it in the Software Center or with:

    sudo apt-get update && sudo apt-get install build-essential

    solved my problem!

  • gcc does not contain g++, these are different packages. Install g++ Install g++:

    apt-get install g++

    Now I'm getting this: CMake Error at /usr/share/cmake-2.8/Modules/FindKDE4.cmake:98 (MESSAGE): ERROR: cmake/modules/FindKDE4Internal.cmake not found in /home/jonquil/.kde/share/apps;/usr/share/kubuntu-default-settings/kde4-profile/default/share/apps;/usr/share/kde4/apps Call Stack (most recent call first): CMakeLists.txt:6 (find_package)

    you are missing a build environment, it's more than just compilers, you need libraries and so on. Take a look here to find out what you need:

    I KNEW there was a package I could install in Ubuntu that would give me all the necessary packages for compiling, I just couldn't remember the name of it. Thanks!

    I'm still getting the same error though. :(

    The error messages hint's at kde - kde development is not included in build-essential. Don't know if there is a meta package for this.

    Could kde-workspace-dev be it? How about kdelibs5-dev?

    I went ahead and installed them both and now it's going smoothly. Still got some unmet dependencies but I should be ok from here... if not I'll post here again!

    I thought I got all my dependencies but now when I type "make" I get this: /usr/local/bin/msgfmt: error while loading shared libraries: cannot open shared object file: No such file or directory make[2]: *** [po/bg/] Error 127 make[1]: *** [po/bg/CMakeFiles/pofiles.dir/all] Error 2 make: *** [all] Error 2

    I have libgettext installed btw. I also have libgettext-ocaml-dev installed.

    Ok, it was a package actually called libgettextsrc. I had to get the RPM version and convert it using Alien. I now have akonadi-google installed on my system. Thanks for all the help! I would vote you a few more times if I could. :D

  • I am aware that this is "Ask Ubuntu", but if someone with Fedora would meet this problem, the following helped me:

    sudo dnf install gcc-c++

    Your are correct in terms of the purpose of this particular forum. Please note that questions - and answers - relating to distros other than Ubuntu Linux should be posted at
