Hello Rich, Orion.

I see you've managed to build pcl that was updated to 1.11 2 months ago but only built recently for Fedora 33+:

https://src.fedoraproject.org/rpms/pcl/commits/master


cloudcompare now FTBFS:


https://koschei.fedoraproject.org/package/cloudcompare?collection=f33


In file included from /usr/include/pcl-1.11/pcl/pcl_macros.h:77,
                 from /usr/include/pcl-1.11/pcl/PCLPointCloud2.h:8,
from /builddir/build/BUILD/CloudCompare-2.9.1/plugins/qPCL/PclUtils/filters/../utils/PCLConv.h:30, from /builddir/build/BUILD/CloudCompare-2.9.1/plugins/qPCL/PclUtils/filters/MLSSmoothingUpsampling.cpp:22: /usr/include/pcl-1.11/pcl/pcl_config.h:7:4: error: #error PCL requires C++14 or above
    7 |   #error PCL requires C++14 or above
      |    ^~~~~


So I've attempted a trivial workaround:

    sed -i 's/-std=c++11/-std=c++14/' $(grep -rl -- '-std=c++11')

or

    sed -i 's/-std=c++11/-std=gnu++14/' $(grep -rl -- '-std=c++11')

However the error is now:


https://koji.fedoraproject.org/koji/taskinfo?taskID=49241500


In file included from /builddir/build/BUILD/CloudCompare-2.9.1/plugins/qPCL/PclUtils/utils/cc2sm.cpp:21: /builddir/build/BUILD/CloudCompare-2.9.1/plugins/qPCL/PclUtils/utils/my_point_types.h:34:12: error: 'uint8_t' in namespace 'boost' does not name a type
   34 |     boost::uint8_t b;
      |            ^~~~~~~


And:

      |                     ^

      |                     ^
/builddir/build/BUILD/CloudCompare-2.9.1/plugins/qPCL/PclUtils/utils/cc2sm.cpp:277:21: error: 'struct OnlyRGB' has no member named 'b'
  277 |    pcl_cloud->at(i).b = static_cast<uint8_t>(rgb[2]);
      |


Any idea what needs to be changed and how? Note that my C++ skills are rusty at least. Thanks for help.
