Situation
Last time we prepared the chroot-environment with debootstrap. This time we continue inside the chroot environment.
Copy to clipboard
chroot /mnt
Inside the chroot we create an user shimps and install aptitude for the other packages' installation process. YMMV.
Copy to clipboard
user="shimps"
addgroup --gid 1000 ${user}
adduser --gid 1000 --uid 1000 --disabled-password --gecos ${user},13,23,42,666 ${user}
apt-get update
apt-get install aptitude
Packages I: General
Next we do some basic preparation of the chroot, independent from the GnuPG build process later.
Copy to clipboard
aptitude install perl
aptitude install libfile-fcntllock-perl
aptitude install bzip2
aptitude install xz-utils
aptitude install libdpkg-perl
aptitude install bash-completion
aptitude install git
aptitude install libldap-common
aptitude install libsasl2-modules
aptitude install publicsuffix
aptitude install openssl
aptitude install ca-certificates
aptitude install openssh-client
aptitude install xauth
aptitude install patch
aptitude install etckeeper
aptitude install vim
update-alternatives --config editor
select-editor
aptitude install systemd-sysv- sysvinit-core
aptitude install psmisc
aptitude remove systemd
aptitude install libsystemd0- libelogind0
aptitude install lsof
aptitude install colordiff
aptitude install wget
aptitude install curl
aptitude install rsync
aptitude install gnupg
Packages II: Build Process
Now we install packages required for compiling GnuPG.
Copy to clipboard
aptitude install gcc
aptitude install libc6-dev
aptitude install libc-devtools
aptitude install manpages
aptitude install manpages-dev
aptitude install make
aptitude install zlib1g-dev
aptitude install libldap-dev
aptitude install libreadline-dev
aptitude install libsqlite3-dev
aptitude install pkgconf
aptitude install gawk
aptitude install libbz2-dev
aptitude install bzip2-doc
aptitude install gpgrt-tools
aptitude install libgnutls28-dev
aptitude install libtasn1-doc
Drop Privileges
Now we switch to a normal user, root privileges aren't needed anymore.
Copy to clipboard
su - ${user}
Clone Repository
As user shimps we clone the diy-gnupg repository from Codeberg and prepare the source code for compilation:
Copy to clipboard
mkdir -p codeberg/fmg
cd codeberg/fmg
git clone https://codeberg.org/fmg/diy-gnupg.git
diy-gnupg/self-compile/bin/fetch-source.sh
diy-gnupg/self-compile/bin/unpack-source.sh
mkdir -p /tmp/canary/install
Compile Libraries
Now things are almost straightforward, similar to what was described earlier in Compiling GnuPG VIII: Dependencies I, but the order has changed.
Copy to clipboard
cd /tmp/canary/compile/npth-1.8
./configure --prefix="/tmp/canary/install"
make
make install
cd ../libgpg-error-1.51
./configure --prefix="/tmp/canary/install"
make
make install
cd ../libassuan-3.0.2
./configure --prefix="/tmp/canary/install"
make
make install
cd ../libksba-1.6.7
./configure --prefix="/tmp/canary/install"
make
make install
cd ../libgcrypt-1.11.0
./configure --prefix="/tmp/canary/install"
make
make install
Compile GnuPG
Now we are close to run into problems with yat2m. This didn't happen before when the package pkgconf wasn't installed, but without this package it wasn't possible to build GnuPG with Sqlite3 support either. The solution is adjusting the PATH variable and to use the new compiled version of yat2m.
Copy to clipboard
PATH="/tmp/canary/install/bin:${PATH}"
cd ../gnupg-2.5.5
./configure --prefix="/tmp/canary/install"
make
make install
LD_LIBRARY_PATH="/tmp/canary/install/lib" gpg --version

Thanks
Many thanks to Andreas for pointing me to the missing pkgconf package problem on the gnupg-devel mailing list.
