go-yara

Go bindings for YARA, staying as close as sensible to the library's C-API while taking inspiration from the yara-python implementation.

YARA 3.4.0 is required. For a version of go-yara that is compatible with YARA 3.3.0, please use the "compat-yara-3.3" branch.

Installation

Unix

On a Unix system with libyara properly installed, this should work, provided that GOPATH is set:

$ go get github.com/hillu/go-yara
$ go install github.com/hillu/go-yara

Depending on what location libyara and its headers have been installed, proper CFLAGS and LDFLAGS may have to be added to cgo.go or be specified via environment variables (CGO_CFLAGS and CGO_LDFLAGS)

Windows

I have not yet built go-yara on Windows, only used the MinGW-w64 provided on Debian. The YARA library was built like this:

$ ./configure --host=i686-w64-mingw32 --disable-magic --disable-cuckoo --without-crypto CFLAGS=-D__MINGW_USE_VC2005_COMPAT
[...]
$ make
$ make install prefix=/path/to/i686-w64-mingw32

I found that the CFLAGS parameter was necessary to avoid problems due to a missing time32 symbol when linking 32bit Windows executables.

Compiling and linking go-yara against this library was achieved like this:

$ CC=i686-w64-mingw32-gcc \
  CGO_ENABLED=1 \
  GOOS=windows GOARCH=386 \
  CGO_CFLAGS=-I/path/to/i686-w64-mingw32/include \
  CGO_LDFLAGS=-L/path/to/i686-w64-mingw32/lib \
  go install --ldflags '-extldflags "-static"' github.com/hillu/go-yara
