Build error: undefined reference to symbol [...]

[ryuuji06]

Hello,

I'm using Ubuntu 18.04, I've build and installed all OpenMVS required libraries, but I got the follwing error during build, as shown below. I have no idea what is that symbol reference.

Can anyone help me?

Thank you

I run either of these commands with OpenMVS:
make
make InterfaceVisualSFM
make ReconstructMesh
make DensifyPointCloud
I always get this error:
undefined reference to symbol 'ZN5boost15program_options29options_description_easy_initclEPKcS3'
Is it the same issue?

[cdcseacave]

pls try the latest release

[elliestath]

Hello, I still get this error with the latest release

[cdcseacave]

I never tested OpenMVS with OpenCV 4.x, pls submit a patch if OpenMVS needs one

[elliestath]

It's OpenCV3.2
dpkg -s libopencv-dev | grep 'Version' Version: 3.2.0+dfsg-4ubuntu0.1

[elliestath]

ok, so it seems I have OpenCV4 under usr/local/include (required for another software) but I have also installed with sudo apt-get -y install libopencv-dev, installed in /usr/share/doc/libopencv-dev and as I wrote above grep shows this version.

I try to make with cmake . ../openMVS -DCMAKE_BUILD_TYPE=Release -DVCG_ROOT="mypath/vcglib" -DEIGEN_INCLUDE_DIR_HINTS=mypath/eigen/include/eigen3 -DEIGEN_DIR=mypath/eigen/include/eigen3 -DOpenCV_DIR="/usr/share/doc/libopencv-dev" -DBUILD_SHARED_LIBS=ON -DOpenCV_CAN_BREAK_BINARY_COMPATIBILITY=OFF
but I get the following output:

I resolve the problem with OpenCV, as I uninstall completely the 4.x and re-install and compile 3.3.1
Now all the dependencies seems to be ok, but still I get this undefined reference to symbol error for both InterfaceCOLMAP and InterfaceVisualSFM. Can I build without these?

My cmake

`cmake . ../openMVS -DCMAKE_BUILD_TYPE=Release -DVCG_ROOT="mypath/vcglib" -DEIGEN_INCLUDE_DIR_HINTS="/usr/local/include/eigen3" -DEIGEN_DIR="/usr/local/include/eigen3" -DBUILD_SHARED_LIBS=ON  -DOpenCV_CAN_BREAK_BINARY_COMPATIBILITY=OFF

[elliestath]

Ok, in my case the problem was solved by setting -DBUILD_SHARED_LIBS=OFF
Do not know if this will cause me a problem later, but for not is is built and installed with no errors.

[jiapei100]

Okay... Yes... I met exactly the same issue.... This is a kind of weird... Maybe openMVS is NOT compatible with OpenCV4 yet...

And @elliestath 's solution works for me...
