@Alex-Kushleyev building Ceres as a dynamically linked library solved it. You are hero material thank you!

@Alex-Kushleyev I'm quite sure that I use the g++ compiler for both builds. neither clang nor msvc are installed.

@Alex-Kushleyev Thanks for the hint. I now added the stdc++ to the linked libs like so:
target_link_libraries(${PROJECT_NAME}_tracker_node stdc++ ${CERES_LIBRARIES})
It still yields the same error sadly. I also tried linking stdc++ in a separate target_link_libraries statement which also yielded the same error.

@Alex-Kushleyev I'm not exactly sure what to look for when looking for the c++ dialect used. There are no CXX_STANDARD statements in either CMakeLists.txt file. So I suppose they are both using the default (don't know what that is).

My project does use C++14 while Ceres 1.14 which I try to include uses c++11 but I tried with c++14 there as well as mentioned previously yielding the same error.

Hi there

I am running a structure from motion pipeline on voxl2 and this pipeline needs in a prior step the bundle adjustment solver Ceres. I know that on voxl this pipeline worked but now for some reason on voxl2 I can build Ceres but when building the project that depends on Ceres I get an error saying that the std::vector = operator is an undefined reference. (see attached image)

Any ideas how to resolve this? I tried moving from c++ 11 in the cmake to c++14 but I think that's a bad approach as the assignment operator for std::vectors was introduced in c++ 98. I also tried using a specific voxl Ceres that I built using voxl docker but that yielded many other errors indicating a doubtful implementation.

Any ideas how to resolve this? Thanks in advance.

I have a stereo camera on the voxel whose images have flickering artifacts due to the auto exposure.

I tried to deactivate the auto exposure by setting the ae_mode parameter to "off" in the voxl-camera -server.config.

This doesn't solve the problem however. Auto exposure still seems to be on and yields the flickering artifact.

How can I resolve this? Did the config parameters change?

Thanks in advance
