You will find instructions for using either Macports or Homebrew below to install the compile-time dependencies.
Install MacPorts according to the instructions found here.
Ensure that Macports' binary paths (
/opt/local/sbin) are in your
PATH environment variable.
# general sudo port install mercurial # YML2 sudo port install py27-lxml # libetpan sudo port install git autoconf automake libtool # asn1c sudo port install asn1c # engine sudo port install gpgme
python is Python 2.7:
sudo port select python python27
Install Homebrew according to the instructions found here.
Ensure that Homebrew's binary path (
/usr/local/bin) is in your
PATH environment variable.
# general brew install mercurial # YML2 # If you don't have pip with your Python 2 distribution, you can install it with brew brew install python pip2 install --user lxml # libetpan brew install git autoconf automake libtool # asn1c brew install asn1c # engine brew install gpgme
To check if lxml is properly installed, you can use this lxml "hello world" command:
python2 -c 'from lxml import etree; root = etree.Element("root"); print(root.tag)'
It should generate the following output:
mkdir -p ~/code/yml2 hg clone https://pep.foundation/dev/repos/yml2/ ~/code/yml2
pEp Engine requires libetpan with a set of patches that have not been upstreamed yet.
mkdir -p ~/code/libetpan git clone https://github.com/fdik/libetpan ~/code/libetpan cd ~/code/libetpan mkdir ~/code/libetpan/build ./autogen.sh --prefix="$HOME/code/libetpan/build" make make install
The MacPorts-packaged GPGME links to a version of GNU libiconv that has files in the same include/library paths as GPGME. This version of libiconv must not be visible to the linker when the pEp Engine is build or run.
Thus the files of the GPGME distribution will have to be manually copied to separate include/library folders, so that no include or library paths used for building the pEp Engine contains files of MacPorts' libiconv distribution.
mkdir -p ~/code/gpgme/build/include cp /opt/local/include/gpg*.h ~/code/gpgme/build/include mkdir -p ~/code/gpgme/build/lib cp -r /opt/local/lib/libgpg* ~/code/gpgme/build/lib
It's of course possible to skip MacPort's version, and use a self-compiled GPGME/GPG. The default build configuration assumes this case, and assumes you have installed your GPGME with
$(HOME) as your prefix.
mkdir -p ~/code/pep-engine hg clone https://pep.foundation/dev/repos/pEpEngine/ ~/code/pep-engine cd ~/code/pep-engine mkdir ~/code/pep-engine/build
Edit the build configuration to your needs in
Makefile.conf, or create a
local.conf that sets any of the make variables documented in
Makefile.conf. All the default values for the build configuration variables on each platform are documented in
If a dependency is not found in your system's default include or library paths, you will have to specify the according paths in a make variable. Typically, this has to be done at least for YML2, and libetpan.
For a more detailed explanation of the mechanics of these build configuration files, and overriding defaults, see the comments in
Below is a sample
./local.conf file, for orientation.
PREFIX=$(HOME)/code/engine/build PER_MACHINE_DIRECTORY=$(PREFIX)/share/pEp YML2_PATH=$(HOME)/code/yml2 ETPAN_LIB=-L$(HOME)/code/libetpan/build/lib ETPAN_INC=-I$(HOME)/code/libetpan/build/include GPGME_LIB=-L$(HOME)/lib GPGME_INC=-I$(HOME)/include
The engine is built as follows:
make all make db
If your build fails with an error message similar to the following:
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/locale.py", line 477, in _parse_localename raise ValueError, 'unknown locale: %s' % localename ValueError: unknown locale: UTF-8
or any other locale-related Python error, make sure Python does not have any locale-related environment variables set.
unset LC_CTYPE is sufficient to take care of the problem, but it depends on your macOS's regional and language settings and which terminal emulator you use.
This is a bug in Python, see https://bugs.python.org/issue18378#msg215215.
The unit tests can be run without the engine library being installed, however
system.db must be installed:
make -C db install
system.db rarely changes, its installation is not needed for every build.
Tests can be compiled and executed with the following commands:
make -C test compile make test
