golang build static binary with gocv

Description

I want to build a golang program static linked with gocv, which used

go build -a -ldflags '-extldflags "-static"' *.go

but it show below

command-line-arguments

How can I fixed it?

If I just build without static, it can run. But I want to put it on other computer without opencv, thks

Your Environment

  • Operating System and version: Ubuntu 18.04.3
  • OpenCV version used: 4.2.0
  • How did you install OpenCV? golang quick install
  • GoCV version used: 0.22.0
  • Go version: o1.13.5 linux/amd64
  • Did you run the env.sh or env.cmd script before trying to go run or go build? No

First, you need build opencv library static (Cmake -D BUILD_SHARED_LIBS:=OFF)

I successfully static builded go+opencv+openvino,+dlib,+ffmpeg Not only with tensorflow(

I met the same problem. Now I had compiled static opencv4.2.0 libraries, then I use externel mode to compile golang program which based on gocv. unfortunately, It cannot work find. Error: OpenCV 4.x+ requires enabled C++11 support

@cnjeffliu , please attach log with errors Maybe /usr/local/opencv/lib/libopencv_core.a need be /usr/local/lib/libopencv_core.a

try

ls /usr/local/opencv/lib/libopencv_core.a
ls /usr/local/lib/libopencv_core.a

go build --ldflags '-extldflags "-static"' -o programm .

Works for me in docker (with openvino)

Danile71 avatar Feb 10 '20 14:02 Danile71

@Danile71 I specified the installed path on /usr/local/opencv when compiled the opencv .

cnzf1 avatar Feb 12 '20 03:02 cnzf1

@cnjeffliu , CGO_LDFLAGS="-L/usr/local/opencv/lib/ -lopencv_core.a...

Danile71 avatar Feb 12 '20 03:02 Danile71

@Danile71 I get the error like 'OpenCV 4.x+ requires enabled C++11 support' as before when compiled the program which based on gocv .

@Danile71 In win 10。 build opencv library static。after go run I get too many errors like this

I had the same issue as at the first message. Then I used the advice of @Danile71 by and ran next commands:

cd ~/go/src/gocv.io/x/gocv
make download
cd /tmp/opencv/opencv-4.2.0/
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_ARCH_BIN=5.3,6.0,6.1,7.0,7.5 -D CUDA_ARCH_PTX=5.3 -D OPENCV_EXTRA_MODULES_PATH=/tmp/opencv/opencv_contrib-4.2.0/modules -D InferenceEngine_DIR=../dldt/inference-engine/build -D WITH_JASPER=OFF -D BUILD_DOCS=OFF -D BUILD_EXAMPLES=ON -D ENABLE_CXX11=ON -D WITH_INF_ENGINE=ON -D WITH_QT=OFF -D WITH_GTK=ON -D WITH_FFMPEG=OFF -D WITH_CUDA=ON -D WITH_TIFF=OFF -D WITH_WEBP=OFF -D WITH_QT=OFF -D WITH_PNG=OFF -D WITH_1394=OFF -D HAVE_OPENEXR=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_opencv_java=NO -D BUILD_opencv_python=NO -D BUILD_opencv_python2=NO -D BUILD_opencv_python3=NO -D BUILD_SHARED_LIBS=OFF -D OPENCV_GENERATE_PKGCONFIG=ON ..
make -j $(shell nproc --all)
make preinstall
sudo make install
sudo ldconfig

I tried to build my app again and it gave me an error with different output. I am not sure that I did everything right. @Danile71 could you advise me? here is my build log and Makefile I used

Does anyone have a working solution for this

I don't have the cmake gui

bnidevs avatar Oct 27 '20 16:10 bnidevs

I use ldd main(the executable file) to find the shared library of the executable file, then find the corresponding static library and link them. Could I solve it?

I met the same problem with gocv v0.25.0, I just can't build a static binary with gocv :( Am I missing something?

I met the same problem with gocv v0.25.0, I just can't build a static binary with gocv :( Am I missing something?

what is the message it prompt? If you add all the library of opencv ,you'll build it successful

meilin-shi avatar Jan 11 '21 10:01 meilin-shi

I am also struggling to achieve a static build

jschank avatar Jan 11 '21 14:01 jschank

any news? that would be a really nice feature to statically build on windows, but I also get errors.

marcown avatar Feb 01 '21 12:02 marcown

This is a new PR to address the static build issue on Linux: https://github.com/hybridgroup/gocv/pull/802

Windows will be worked on in a subsequent PR.

deadprogram avatar Feb 07 '21 18:02 deadprogram

Has the work already started for a static build on windows?

cavus700 avatar Mar 12 '21 08:03 cavus700

I tested it today on Ubuntu Linux 20.04 LTS and it works perfectly throughout all the installation and compilation process.

But after building with:

go build -tags static --ldflags '-extldflags "-static"'

It gives me the following runtime errors:

terminate called after throwing an instance of 'cv::Exception'
  what():  OpenCV(4.5.3) /tmp/opencv/opencv-4.5.3/modules/imgproc/src/smooth.dispatch.cpp:617: error: (-215:Assertion failed) !_src.empty() in function 'GaussianBlur'

Is there any news on this?

At risk of piling on the "we want to statically compile gocv so we can use anything that uses it standalone on production" - I think the main supported OS/s really need this. Throwing in MacOS here. Thanks for all the hard work on the Windows one! PS - Will check back in 2 years :D

It looks like this is almost working, I got 3 linking errors though.

I'm trying to build without using libdc1394-devel and gtk2-devel then I'm getting the following error:

command-line-arguments

/usr/lib/golang/pkg/tool/linux_amd64/link: running g++ failed: exit status 1 /usr/bin/ld: cannot find -littnotify: No such file or directory /usr/bin/ld: cannot find -llibprotobuf: No such file or directory /usr/bin/ld: cannot find -lIlmImf: No such file or directory /usr/bin/ld: cannot find -lquirc: No such file or directory /usr/bin/ld: cannot find -lippiw: No such file or directory /usr/bin/ld: cannot find -lippicv: No such file or directory /usr/bin/ld: cannot find -lade: No such file or directory /usr/bin/ld: cannot find -lquadmath: No such file or directory collect2: error: ld returned 1 exit status

using amazon linux image. Maybe those 2 missing packages could produce those errors?

I know this is only ~1.5 years later, but can this be used standalone yet?

So after some testing around i succeded in building a single binary file in windows . Consider adding it to the documentation if needed.

first as before you need to build a static opencv lib. for me in windows its as simple as using the provided batch script win_build_opencv.cmd calling it from a terminal and adding static as an argument

win_build_opencv.cmd static

when building your go excutable simply use the following command

go build -tags static -ldflags="-extldflags=-static" main.go

you can add a -x to see the output . This will result in a single excutable file that is staticly built in windows. I have not test it in linux but i assume the same principle applies there

Great to hear, and thanks so much for the info @ajmandourah! I have been thinking to try this again soon (on Linux primarily, but also Windows). Will make sure to report any progress.
