# Building for OS X/macOS

See also README.txt for general information.

## Dependencies

### MacPorts

Install [MacPorts](https://www.macports.org/) for your

[version of OS X/macOS](https://www.macports.org/install.php).

Note that you need [Xcode installed](https://www.macports.org/install.php)

for MacPorts, and for building the engine. You also need to accept Xcode's EULA.

*Note*: Use the script `macports_env.sh` (or a similar one) to set up a clean build environment

before building the engine:

```

. macports_env.sh

```

If you don't use that environment, please make sure you've set up all search paths correctly.

#### MacPorts dependencies

```

sudo port install mercurial

sudo port install py27-lxml

sudo port install gpgme

sudo port install autoconf

sudo port install asn1c

sudo port install zlib

```

### Other dependecies

#### [yml2](https://fdik.org/yml/toolchain)

Install into your home directory:

```

pushd ~

hg clone https://cacert.pep.foundation/dev/repos/yml2/

popd

```

#### libetpan

Note: libetpan needs libz and libiconv, but the libiconv from MacPorts is not compatible, some

functions seem to have been renamed there. Therefore the dynlib from OS X is used.

```

git clone https://github.com/fdik/libetpan libetpan-osx

cd libetpan-osx/

./autogen.sh

make

cp ./src/.libs/libetpan.a ~/lib/

```

##### libetpan with xcodebuild

The build with autoconf (see previous section) is preferred. This is just for completeness.

*Don't actually build libetpan with xcodebuild.*

```

git clone https://github.com/fdik/libetpan libetpan-osx

cd libetpan-osx/build-mac

xcodebuild -project libetpan.xcodeproj/ -target "static libetpan"

mkdir ~/lib

cp build/Release/libetpan.a ~/lib/

```

### Configuration

You can change some defaults by editing `Makefile.conf`. But this readme assumes you don't.

### Build

```

make clean

make all

make db

```

Done! The result should be (among others):

```

./src/libpEpEngine.a

./src/libpEpEngine.dylib

```

### Install

Install (you might need sudo for some commands, depending on how your system is set up):

```

make install

make -C db install

```

Since the `system.db` rarely changes, `make -C db install` is not needed for every build.

### Run tests

Make sure that you add `/opt/local/lib` to each definition of `LD_LIBRARY_PATH`

in `test/Makefile`. This ensures that libgpgme will be found:

```

test: pEpEngineTest

        LD_LIBRARY_PATH=/opt/local/lib:~/lib:../src ./pEpEngineTest

```

```

make test

```

# Building for iOS

This is done with Xcode. Simply add `pEpEngine.xcodeproj` to

your project and add a dependency to the target `pEpEngine`

(in `Target Dependencies` in your `Build Phases`.

Usually you just integrate `pEpiOSAdapter.xcodeproj`.
