Compiling for Windows instructions about go-yara HOT 15 CLOSED

@chennqqi

This is what I did to compile Windows 64-bit libyara.a. I did all compilation in a Ubuntu docker image using MinGW-w64

> docker run -t -i ubuntu:latest /bin/bash

And these are the exact commands I performed.

apt-get update
apt-get install build-essential git
apt-get install gcc-multilib gcc-mingw-w64 autoconf automake libtool libjansson-dev libmagic-dev libssl-dev
git clone --depth=50 https://github.com/VirusTotal/yara.git VirusTotal/yara
export CONFIGFLAGS=--host=x86_64-w64-mingw32
export CC=gcc
cd VirusTotal/yara
./bootstrap.sh
unset CC
./configure $CONFIGFLAGS
make
cd libyara/.libs
file libyara.a

Worked like a charm.... I was able to incorporate this libyara.a into this go-yara project

I had to do one modification and create a cgo_windows.go file with the following CGO instructions. I also copied the .H headers into a new ./include folder and the windows lib into a new ./lib folder

// +build windows

package yara

/*
#cgo CFLAGS: -I${SRCDIR}/include
#cgo amd64 LDFLAGS: -L${SRCDIR}/lib -lyara64
#cgo 386 LDFLAGS: -L${SRCDIR}/lib -lyara32
*/
import "C"
...

and modified the old cgo.go file to:

// +build !windows

package yara

/*
#cgo CFLAGS: -I${SRCDIR}/include
#cgo LDFLAGS: -lyara
*/
import "C"

Now I can build from my Sierra macOS both Darwin and Windows executables of my project that is using go-yara package with the following command to target Windows:

CC=/usr/local/Cellar/mingw-w64/4.0.6/bin/x86_64-w64-mingw32-gcc \
LD=/usr/local/Cellar/mingw-w64/4.0.6/bin/x86_64-w64-mingw32-ld \
  CGO_ENABLED=1 \
  GOOS=windows \
  CGO_CFLAGS=-I/usr/local/Cellar/mingw-w64/4.0.6/x86_64-w64-mingw32/include \
  CGO_LDFLAGS=-L/usr/local/Cellar/mingw-w64/4.0.6/x86_64-w64-mingw32/lib \
  go build --ldflags '-extldflags "-static"' .

And voilà !!! Works like a charm.... I have tested the binary on Windows 10 x64 and works very well... without any dependencies.

It took a while to figure it out. Hopefully this will help other people... Maybe we should move this instructions to the Readme ? Feedback ?

@chennqqi Neither -I/usr/i686-w64-mingw32/include nor -L/usr/i686-w64-mingw32/lib should be necessary, the MinGW compiler includes those search paths by default.

from go-yara.

Both msys and msys2 work correctly.
Compile libyara by mingw-gcc.

from go-yara.

@mcastilho So you are still using the libyara32 and libyara64 generated through the VS project? Do you think that it would make sense to add a build tag, say vs?

#cgo windows,vs,i386 LDFLAGS: -lyara32
#cgo windows,vs,amd64 LDFLAGS: -lyara64

from go-yara.

No. I am not using the VIsual studio output. I don't think is compatible. I am using the binaries produced by the compilation under Ubunto using MingGW

from go-yara.

In that case, the resulting libraries should simply have the name libyara.a (without a 32 or 64 prefix), shouldn't they? Unless you have renamed them, of course.

from go-yara.

Yes. I did rename them

from go-yara.

Would you mind looking at my updated build/install instructions and tell me if they work for you?

from go-yara.

@mcastilho I did that under windows and linux.

1. build static libyara and install to a libyara_path
sudo yum install mingw32-gcc
./configure --build=i686-w64-mingw32 --without-crypto --disable-shared --disable-dependency-tracking --disable-magic --disable-cuckoo --without-crypto
   make && sudo make install prefix=/usr/i686-w64-mingw32/
   `
2. build go-yara and link libyara_path
   i386-windows:
   CC=i686-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=386 CGO_CFLAGS=-I/usr/i686-w64-mingw32/include CGO_LDFLAGS='-L/usr/i686-w64-mingw32/lib -lyara' go install --ldflags '-extldflags "-static"' github.com/hillu/go-yara
   x64-linux:
   CGO_ENABLED=1 GOOS=linux GOARCH=amd64 CGO_CFLAGS=-I/usr/include CGO_LDFLAGS='-L/opt/x86_64/lib -lyara -lm' go install --ldflags '-extldflags "-static"' github.com/hillu/go-yara
3. build your app with link libyara_path
   x64-linux:
   CGO_ENABLED=1 GOOS=linux GOARCH=amd64 CGO_LDFLAGS='-L/opt/x86_64/lib -L/usr/lib64' go build --ldflags '-s -w -extldflags "-static -lm"' YOURAPPPATH
   ...other environment.

May this help you. Happy chinese new year!

I got error when I built go-yara:
could not determine kind of name for C.ERROR_INSUFICIENT MEMORY

I tried building with all of instructions, in all cases - this error. Tried on Debian and Ubuntu - same thing.
go version - 1.8

=============== [SOLVED] ====================

just correct in error.go: C.ERROR_INSUFICIENT_MEMORY to C.ERROR_INSUFFICIENT MEMORY ))) just add "F" letter

from go-yara.

oh, awesome, Fixing typos in YARA after 3.5 breaks the API...

Closing the issue since everything discussed here has been resolved.

I followed the above steps, but returned the error " /usr/bin/x86_64-w64-mingw32-ld: unable to find - lyara64 ". Could you help me solve it ?

from go-yara.

@Jacob-Dong The error

/usr/bin/x86_64-w64-mingw32-ld: unable to find - lyara64

tells you that the linker that is invoked for linking the final program or library does not find libyate64.a, libyara64.so or libyara64.dll in the search path for libraries (parameter -L, usually specified via LDFLAGS environment variable.)

If you built YARA from sources, it's most likely that libyara.a and libyara.so.* was generated, so the -lyara64 parameter would be wrong.

Thanks for answering. Actually as you said, so I modified the " -lyara64 " of cgo_windows.go to "-lyara", then the error disappered.
