VMime is the library we intend to use in Mail2Voice Next. It supports emails protocols such as IMAP and SMTP. Visit http://vmime.org for more informations.

Packages needed:

• git
• cmake
• build-essential
• pkg-config
• libgsasl7
• libgsasl7-dev
• libgnutls-dev
• libssl-dev
• sendmail
• doxygen

One can install all the stuff needed with the following command:

sudo apt-get install -y git cmake build-essential pkg-config libgsasl7 libgsasl7-dev libgnutls-dev libssl-dev sendmail doxygen

git clone https://github.com/kisli/vmime.git
mkdir vmime/build
cd vmime/build
cmake -DVMIME_BUILD_SAMPLES=OFF -DVMIME_SHARED_PTR_USE_BOOST=OFF -DVMIME_SHARED_PTR_USE_CXX=ON -DVMIME_SENDMAIL_PATH=/run/sendmail -DCMAKE_BUILD_TYPE=RELEASE ..
make
sudo make install

1. Download and install MinGW64 from sourceforge (https://sourceforge.net/projects/mingw-w64/).
   1. Use the following settings:
      1. Version: latest (6.2.0 on 2016-09-21)
      2. Architecture: x86_64
      3. Threads: win32
      4. Exception: seh
      5. Build revision: 1
   2. And install it on “C:\” (it will create a mingw64 directory)
2. Download MSYS (https://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/MSYS%20%2832-bit%29/ ). On 2016-09-21, the latest version is MSYS-20111123.zip.
   1. Extract the msys folder to “C:\”
   2. Run C:\msys\msys.bat, it will open a unix-like terminal
   3. From this terminal, run: sh /postinstall/pi.sh
   4. Answer “y” for the two first questions.
   5. Enter the path to your mingw64 installation (C:/mingw64) in our case. Make sure to use “/” instead of “\”.
   6. It should “Normalizing your MSYS environment”.
3. Download and install CMake (https://cmake.org/download/)
   1. When installing, choose to add CMake to the “path” environment variable.

1. Download GSASL from ftp://ftp.gnu.org/gnu/gsasl/ (latest version is 1.8.0 on 2016-09-21) and extract files.
2. Open C:\msys\msys.bat
3. Then type the following commands :

  $ cd /path/to/your/libgsasl_src_dir/ (i.e. /c/Users/MrNobody/dev/libgsasl-1.8.0/)
  $ mkdir build
  $ cd build
  $ ../configure --prefix=/path/to/your/libgsasl_src_dir/dist
  $ make
  $ make install

Fortunately, the Winbuilds project offers some precompiled dependencies we need. You can download the following packages from http://win-builds.org/doku.php/1.5.0_packages:

• gnutls
• pkg-config
• win-iconv

Finally, you can compile VMime using the following commands:

  $ git clone https://github.com/kisli/vmime.git
  $ mkdir vmime/build
  $ cd vmime/build
  $ export DEPS=/path/to/dependencies/parent/dir
  $ cmake .. -G "MinGW Makefiles" -DCMAKE_CXX_COMPILER=/C/mingw64/bin/g++.exe -DCMAKE_C_COMPILER=/C/mingw64/bin/gcc.exe \
  -DCMAKE_MAKE_PROGRAM=/C/mingw64/bin/mingw32-make.exe -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=/C/Users/MrNobody/dev/vmime-master/install \
  -DGNUTLS_INCLUDE_DIR=$DEPS/gnutls-3.2.21/include -DGNUTLS_LIBRARY=$DEPS/gnutls-3.2.21/lib64/libgnutls.dll.a \
  -DGSASL_INCLUDE_DIR=$DEPS/libgsasl-1.8.0/include -DGSASL_LIBRARIES=$DEPS/libgsasl-1.8.0/lib/libgsasl.dll.a \
  -DICONV_INCLUDE_DIR=$DEPS/win-iconv-0.0.6/include -DICONV_LIBRARIES=$DEPS/win-iconv-0.0.6/lib64/libiconv.dll.a \
  -DPKG_CONFIG_EXECUTABLE=$DEPS/pkg-config/bin/pkg-config.exe -DVMIME_CHARSETCONV_LIB=iconv \
  -DVMIME_BUILD_DOCUMENTATION=OFF -DVMIME_BUILD_SAMPLES=OFF -DVMIME_BUILD_TESTS=OFF \
  -DVMIME_HAVE_MLANG_H=OFF -DVMIME_HAVE_MLANG_LIB=OFF -DVMIME_HAVE_MESSAGING_PROTO_SENDMAIL=OFF \
  -DVMIME_SHARED_PTR_USE_BOOST=OFF -DVMIME_SHARED_PTR_USE_CXX=ON
  $ mingw32-make.exe
  $ mingw32-make.exe install

Note 1: you may encounter some errors while generating the Makefile mentioning that libglib2 is missing but you can ignore it.

Note 2: if the install step fails at the end, just copy the missing libvmime.dll file from the build/build/bin directory into the install/bin directory.
