Cross-compiling for Windows

Cross-compiling Windows binaries from a Linux development machine is a slightly more complicated process. Firstly you will need to install MingW and some other dependencies:
$ sudo apt install gcc mingw-w64 automake libtool make go-bindata
Next you will need to download Yara sources. Use the latest available version, which at the time of this writing is 4.0.1:
$ wget
Unpack the archive and export YARA_SRC to the newly-created folder:
$ export YARA_SRC=<folder>
Next you need to bootstrap Yara sources and compile them with MingW. These are the instructions to compile it for 32bit:
$ cd ${YARA_SRC}
$ ./
$ ./configure --host=i686-w64-mingw32 --disable-magic --disable-cuckoo --without-crypto --prefix=${YARA_SRC}/i686-w64-mingw32
$ make -C ${YARA_SRC}
$ make -C ${YARA_SRC} install
Now we can download and build go-yara for 32bit using the following command:
$ go get -d -u
$ GOOS=windows GOARCH=386 CGO_ENABLED=1 \
CC=i686-w64-mingw32-gcc \
PKG_CONFIG_PATH=${YARA_SRC}/i686-w64-mingw32/lib/pkgconfig \
go install -ldflags '-extldflags "-static"'
Now you can compile Kraken using:
$ RULES=test/ make windows
If you get errors such as undefined reference to 'yr_compiler_add_file' you might need to pass the PKG_CONFIG_PATH variable:
$ PKG_CONFIG_PATH=${YARA_SRC}/i686-w64-mingw32/lib/pkgconfig RULES=test/ make windows
