Compilation of OpenEB on RHEL8

[stephetw]

Hello,

I was able to successfully build openeb-5.0.0 on RHEL8. Admittedly, I am green with this, there are a few things that I modified that I do not understand what implications may be as a result. Of course, this is on an unsupported OS, so I understand if this is discarded.

The following are errors during the compilation step:

<OPENEB_SRC_DIR>/sdk/modules/core/cpp/src/utils/video_writer.cpp:354:33: error: no matching function for call to ‘Metavision::VideoWriter::write(const cv::_InputArray&)’
     cv::VideoWriter::write(image);

Solution:

Modify <OPENEB_SRC_DIR>/sdk/modules/core/cpp/src/utils/video_writer.cpp, starting line 351:

#if CV_MAJOR_VERSION >= 3 && CV_MINOR_VERSION == 2
    cv::VideoWriter::write(image.getMat(-1));
#else
    cv::VideoWriter::write(image);
#endif

To just:
cv::VideoWriter::write(image.getMat(-1));

<OPENEB_SRC_DIR>/sdk/modules/core/cpp/src/utils/video_writer.cpp:377:72: error: no matching function for call to ‘Metavision::VideoWriter::operator<<(const cv::UMat&)’
     return static_cast<VideoWriter &>(cv::VideoWriter::operator<<(image));

Solution:

Modify <OPENEB_SRC_DIR>/sdk/modules/core/cpp/src/utils/video_writer.cpp, starting line 373:

#if CV_MAJOR_VERSION >= 3 && CV_MINOR_VERSION == 2
    MV_SDK_LOG_ERROR() << "VideoWriter :" << Metavision::Log::function << "not implemented";
    return *this;
#else
    return static_cast<VideoWriter &>(cv::VideoWriter::operator<<(image));
#endif

To:

#if CV_MAJOR_VERSION >= 3 && CV_MINOR_VERSION == 2
    MV_SDK_LOG_ERROR() << "VideoWriter :" << Metavision::Log::function << "not implemented";
    return *this;
#else
    return *this;
#endif

Various errors with:

undefined reference to `std::filesystem::__cxx11::path::_M_split_cmpts()'

Solution:

Prepend link_libraries(stdc++fs) to <OPENEB_SRC_DIR>/CMakeLists.txt

error: ‘setw’ is not a member of ‘std’

In Files:

• <OPENEB_SRC_DIR>/hal/cpp/src/facilities/i_ll_biases.cpp
• <OPENEB_SRC_DIR>/hal_psee_plugins/src/devices/genx320/genx320_roi_driver.cpp

error: ‘put_time’ is not a member of ‘std’

In File:

• <OPENEB_SRC_DIR>/sdk/modules/stream/cpp/src/synced_camera_system_factory.cpp

Solution:

Add header: #include <iomanip>

@stephetw
Thanks for reporting those various issues.
I tried fixing them in this PR: #133
Could you confirm whether this fixes things on your end?

One thing I am not sure we'll want to keep is the link_libraries(stdc++fs) as it appears to be only necessary for compilers older than GCC-9 . And I am not sure we want to support this since it is a bit old.

@jthierry-psee
Awesome thank you for the quick response!

I can confirm that this PR fixes all of the issues I saw.

I did try again with GCC 12.2.1, and removing link_libraries(stdc++fs). This built successfully, but there were various errors:
