    How To: Compile and Install GnuPG from source with Camellia and IDEA ciphers

    HowTo Compile GnuPG with IDEA and Camellia Ciphers

    **Updated to Include GPG and GPG2

    PreRequisite Packages for Both Version

    1. Dependencies:
    build-essential, linux-header files, subversion, automake

    (Cut and paste following inside terminal to install necessary dependencies)
    Code:
    sudo aptitude install build-essential linux-headers-$(uname -r) subversion automake checkinstall
    2. Working Directory Structure (Using this directory structure so guide is coherent. You may choose to download your svn sources and libs and place them in a different directory)

    Code:
    mkdir -p ~/src
    cd ~/src
    mkdir -p gnupg
    mkdir -p gnupg2
    Compilation of GnuPG (GnuPG Version 1)
    ***Platforms Tested: Ubuntu, Cygwin (Although installation steps are slightly different)

    Requirements
    1. SVN sources of GnuPG
    2. IDEA module (Optional)
    3. BZIP2 Developmental library

    We will be using the GnuPG svn stable branch

    GnuPG (Version 1) SVN Source Files

    Code:
    cd ~/src
    svn co svn://cvs.gnupg.org/gnupg/branches/STABLE-BRANCH-1-4 gnupg
    cd gnupg
    (Optional) IDEA module

    Code:
    cd ~/src/gnupg/cipher
    wget ftp://ftp.gnupg.dk/pub/contrib-dk/idea.c.gz
    gunzip idea.c.gz
    cd ~/src/gnupg
    BZIP2 library

    Code:
    sudo aptitude install libbz2-dev
    Compile GnuPG enabling camellia and idea ciphers
    Code:
    ./autogen.sh --force
    ./configure --enable-camellia --enable-idea --enable-maintainer-mode
    make
    make check
    
    Choose one of the Following Options (First Option Recommended if Installing Within the Apt Packaging System):
    sudo checkinstall -D --fstrans=no --install=yes --pkgname gnupg --pkgversion svn-`svn info|grep Revision |cut -f2 -d' '`
    sudo make install
    gnupg.exe will be installed to /usr/local/bin. You need to ensure in your PATH environment variable that /usr/local/bin is listed before /usr/bin (echo $PATH). This is normally to the case unless the path statement has been modified.

    To check the ciphers available with gpg
    Code:
    gpg --version
    Example showing installed gpg version:
    Code:
    $  gpg --version
    gpg (GnuPG) 1.4.10-svn4881

    Updating the GnuPG and GnuPG2 Installation

    Since both GnuPG and GnuPG2 were installed from svn source packages, it is easy to update the packages when new svn sources are released.


    Updating the GnuPG Installation

    Code:
    cd ~/src/gnupg
    svn up
    rm -rf autom4te.cache
    ./autogen.sh && ./configure --enable-maintainer-mode --enable-camellia --enable-idea && make
    
    Depending on the method Used to Install the Original Installation (Choose One of the following):
    sudo checkinstall -D --fstrans=no --install=yes --pkgname gnupg --pkgversion svn-`svn info|grep Revision |cut -f2 -d' '`
    sudo make install

    Updating the GnuPG2 Installation

    Code:
    cd ~/src/gnupg2
    svn up
    rm -rf autom4te.cache
    ./autogen.sh && ./configure --sysconfdir=/etc --enable-maintainer-mode --enable-camellia && make
    
    Depending on the method Used to Install the Original Installation (Choose One of the following):
    sudo checkinstall -D --fstrans=no --install=yes --pkgname gnupg2 --pkgversion svn-`svn info|grep Revision |cut -f2 -d' '`
    sudo make install

    Thank you kevdog. I have just made and installed GnuPG with IDEA, couldn't have done it without these instructions.

    I do not have msgmerge (Gutsy install), so the autogen.sh script was failing. Commenting out the check allowed it to proceed.

    Could you tell me what msgmerge is?? I'm unfamiliar with this tool and might update the instructions based on your response.

    Updated to include checkinstall method to introduce installation within the apt packaging system.

    Re: How To: Compile and Install GnuPG from source with Camellia and IDEA ciphers

    Kevdog,

    Thanks so much!! I was beginning to wonder if anyone was ever going to reply to one of my posts!

    I had seen this article you reference before, but I was leery about implementing it, because I didn't know how it would interact with apt/synaptic/etc. when new releases came out for GPG on Ubuntu. But I'll give it a shot now that you indicate it is the preferred solution.

    By the way (and this is probably better suited for the Absolute Beginner's forum), is there a way to get the source code with apt (or apt-get, etc.) and then build GPG with debuild or something like that (having included the IDEA module, of course)? I think that might be a little better to work with the Ubuntu system.

    Thanks again!

    Sincerely,
    Jeffrey Rolland

    Re: How To: Compile and Install GnuPG from source with Camellia and IDEA ciphers

    Just my opinion

    I would still use the sudo make install method rather than checkinstall to install the svn sources of gnupg. SVN are the latest and greatest releases, although they might theoretically not be stable (although Ive never run into this situation before!). The SVN version is usually many generations ahead of the version offered in the Ubuntu repositories and allows for bug fixes.

    Because you are compiling from source and installing outside the apt system (when using sudo make install), the binaries will be placed within the /usr/local tree -- such as in /usr/local/bin. Its possible to keep Ubuntu's repository version installed in the system since this is installed within the /usr tree -- such as /usr/bin. Hence its possible to have two version of gnupg on the system at the same time. The directories listed in you $PATH environment variable will show which directory path is preferred, although by default, /usr/local/bin is preferred over /usr/bin.

    There is no other way I know how to get the sources other than from svn or downloading the .tar.gz or .tar.bz2 files directly. It may be possible to grab the source using apt, however this likely gives you no advantage to using the binary version, since its the same version (although I suppose you could add the idea module into the default source tree). My recommendation -- stick with svn tree if possible.

    Hopefully that answered your questions somewhat!

    Re: How To: Compile and Install GnuPG from source with Camellia and IDEA ciphers

    OK, I followed the HowTo (so perfectly written - thank you so much!), using the checkinstall option, and gpg now runs fine - with IDEA! - from the command line.

    I didn't do the optional "Generating the gpg.conf directory" set of instructions.

    However, now I can't use Seahorse. Actually, more precisely, the program "Passwords and Encryption Keys" won't load, and when I double-click on a .gpg (or .pgp) file - or right-click a .gpg (or .pgp) file and select "Open with 'Decrypt File'" - nothing happens.

    Is there a simple fix to make this gpg work from the GUI again?

    Thanks for all your help!

    Sincerely,
    Jeffrey Rolland

    Re: How To: Compile and Install GnuPG from source with Camellia and IDEA ciphers

    I never use seahorse, so I might be out in left field here, but is there a path conflict perhaps -- meaning it can't find it located in /usr/bin?

    Re: How To: Compile and Install GnuPG from source with Camellia and IDEA ciphers

    When I try to launch seahorse from the command line, I get the error messages

    ** Message: init gpgme version 1.1.6

    ** (seahorse:16667): CRITICAL **: init_gpgme: assertion `GPG_IS_OK (err)' failed

    ** (seahorse:16667): CRITICAL **: seahorse_pgp_source_init: assertion `GPG_IS_OK (gerr)' failed
    Segmentation fault

    Does this mean anything to anyone?
