There are only a few packages that need to be installed as root to get started:
- sudo apt-get install gcc-mingw32 mingw64 git-core wget
+ sudo apt-get install mingw-w64 git-core wget quilt
sudo apt-get build-dep tinc
Other Linux distributions may also have 64-bit MinGW packages, use their respective
package management tools to install them. Debian installs the cross-compiler
-in `/usr/amd64-mingw32msvc/`. Other distributions might install it in another
+in `/usr/x86_64-w64-mingw32/`. Other distributions might install it in another
directory however. Check in which directory
-it is installed, and replace all occurences of `amd64-mingw32msvc` in this
+it is installed, and replace all occurences of `x86_64-w64-mingw32` in this
example with the correct name from your distribution.
-At the time of writing, the gcc-mingw32 package contains the 64-bit compiler as
-well, in the future this might be put into its own package. Also, a header file
-is missing in the amd64-mingw32msvc include directory, a workaround is to
-create a symlink to the otherwise identical 32-bit version of that header file:
-
- ln -s ../../i586-mingw32msvc/include/getopt.h /usr/amd64-mingw32msvc/include/getopt.h
-
### Setting up the build directory and getting the sources
We will create a directory called `mingw64/` in the home directory. We use
mkdir $HOME/mingw64
cd $HOME/mingw64
- apt-get source liblzo2-dev zlib1g-dev
- wget http://www.openssl.org/source/openssl-1.0.0.tar.gz
- tar xzf openssl-1.0.0.tar.gz
+ apt-get source liblzo2-dev zlib1g-dev libssl-dev
git clone git://tinc-vpn.org/tinc
### Making cross-compilation easy
use the 64-bit MinGW version of GCC and binutils:
mkdir $HOME/bin
- cat >$HOME/bin/mingw64 << EOF
+ cat >$HOME/bin/mingw64 << 'EOF'
#!/bin/sh
- export CC=amd64-mingw32msvc-gcc
- export CXX=amd64-mingw32msvc-g++
- export CPP=amd64-mingw32msvc-cpp
- export RANLIB=amd64-mingw32msvc-ranlib
- export PATH="/usr/amd64-mingw32msvc/bin:$PATH"
+ PREFIX=x86_64-w64-mingw32
+ export CC=$PREFIX-gcc
+ export CXX=$PREFIX-g++
+ export CPP=$PREFIX-cpp
+ export RANLIB=$PREFIX-ranlib
+ export PATH="/usr/x86_64-w64-mingw32/bin:$PATH"
exec "$@"
EOF
chmod u+x $HOME/bin/mingw64
Cross-compiling LZO is easy:
- cd $HOME/mingw64/lzo2-2.03
- ./configure --host=amd64-mingw32msvc
+ cd $HOME/mingw64/lzo2-2.08
+ ./configure --host=x86_64-w64-mingw32
make
DESTDIR=$HOME/mingw64 make install
Cross-compiling Zlib is also easy, but a plain `make` failed to compile the
tests, so we only build the static library here:
- cd $HOME/mingw64/zlib-1.2.3.3.dfsg
- mingw64 ./configure
- mingw64 make libz.a
+ cd $HOME/mingw64/zlib-1.2.8.dfsg
+ mingw64 ./configure --static
+ mingw64 make
DESTDIR=$HOME/mingw64 mingw64 make install
-### Compiling OpenSSL
+### Compiling LibreSSL
-Although older versions will not compile, OpenSSL 1.0.0 is easy.
-However, `apt-get source` will have applied
-Debian-specific patches that break cross-compiling a Windows binary.
-You need to undo those patches first.
-Do not use the `-j` option when compiling OpenSSL, it will break.
+Tinc can use either OpenSSL or LibreSSL. The latter is recommended.
- cd $HOME/mingw64/openssl-1.0.0
- quilt pop -a
- mingw64 ./Configure --openssldir=$HOME/mingw64/usr/local mingw64
- mingw64 make
- mingw64 make install
+ cd $HOME/mingw/libressl-2.3.3
+ CC=x86_64-w64-mingw32-gcc ./configure --host=x86_64-w64-mingw32
+ make
+ DESTDIR=$HOME/mingw make install
### Compiling tinc
cd $HOME/mingw64/tinc
autoreconf -fsi
- ./configure --host=amd64-mingw32msvc --with-openssl=$HOME/mingw64/usr/local
+ ./configure --host=x86_64-w64-mingw32 --with-zlib=$HOME/mingw64/usr/local
make
